It sits at the center of a long-running tension in competition policy: most such contracts encourage dealers to specialize in promoting a brand, yet a web of them can lock up distribution and keep an entrant from ever reaching the scale needed to compete<sup>[1](https://www.ftc.gov/advice-guidance/competition-guidance/guide-antitrust-laws/dealings-supply-chain/exclusive-dealing-or-requirements-contracts)</sup>.\n\n| Key fact | Detail |\n|---|---|\n| Definition | An arrangement inducing a buyer to purchase most or all requirements for a period from one supplier; judged under the rule of reason in the US<sup>[1](https://www.ftc.gov/advice-guidance/competition-guidance/guide-antitrust-laws/dealings-supply-chain/exclusive-dealing-or-requirements-contracts)</sup><sup> • </sup><sup>[3](https://download.pli.edu/WebContent/pm/357816/pdf/10-12-2023_0905_141661_Handout2.pdf)</sup> |\n| US thresholds | Older agency guidance describes foreclosure of 30% or less as generally safe; Section 1 concern usually requires 40–50%; no safe harbor for monopolists under Section 2<sup>[4](https://appliedantitrust.com/20_exclusive_contracts/doj_section2_report_exclusive_dealing.pdf)</sup><sup> • </sup><sup>[5](https://www.thesedonaconference.org/sites/default/files/publications/43-50%20Baker_0.pdf)</sup> |\n| EU thresholds | Vertical block exemption requires supplier and buyer shares each at or below 30%; non-competes capped at five years; cumulative networks above 50% can lose exemption<sup>[6](https://eur-lex.europa.eu/eli/reg/2022/720/oj/eng)</sup> |\n| Landmark US cases | Standard Stations (1949), Tampa Electric (1961), Dentsply (2005), Microsoft (2001), Surescripts, Google (2025)<sup>[7](https://www.thesedonaconference.org/sites/default/files/publications/51-56%20Rosch_0.pdf)</sup><sup> • </sup><sup>[8](https://digitalcommons.law.villanova.edu/cgi/viewcontent.cgi?article=2495&context=thirdcircuit_2005)</sup><sup> • </sup><sup>[9](https://www.ftc.gov/enforcement/competition-matters/2026/02/how-loyalty-discounts-between-firms-harm-competition-when-there-are-network-effects-ftc-v-surescripts)</sup> |\n| Economic mechanism | With a minimum efficient scale, an incumbent can profitably exclude by signing enough customers that no rival can reach scale; 86 of 100 customers can suffice when the scale threshold is 15<sup>[10](https://rasmusen.org/published/Rasmusen_91.AER.exclusion.htm)</sup> |\n| Efficiency rationale | Exclusivity protects relationship-specific investments (special equipment, training) and encourages dealer marketing support<sup>[2](https://www.internationalcompetitionnetwork.org/wp-content/uploads/2018/07/UCWG_UCW_Ch5.pdf)</sup><sup> • </sup><sup>[11](https://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=intcom%3AC%282022%294238)</sup> |\n\n## What exclusive dealing is\n\nThe term covers a family of arrangements with the same economic effect. An exclusive dealing contract prevents a distributor from selling the products of a different manufacturer; a requirements contract prevents a manufacturer from buying inputs from a different supplier<sup>[1](https://www.ftc.gov/advice-guidance/competition-guidance/guide-antitrust-laws/dealings-supply-chain/exclusive-dealing-or-requirements-contracts)</sup>. The International Competition Network's workbook adds the reverse case, where a downstream purchaser requires an upstream seller not to sell to competing downstream purchasers, and notes that exclusivity can arise de facto through discounts or rebates conditional on buying all or a substantial part of requirements from one supplier<sup>[2](https://www.internationalcompetitionnetwork.org/wp-content/uploads/2018/07/UCWG_UCW_Ch5.pdf)</sup>.\n\nExclusivity is distinct from tying. Tying is an agreement to sell one product only on condition that the buyer also purchases a different product, and it remains the vertical restraint to which the per se rule nominally applies; exclusive dealing instead induces a buyer to concentrate purchases over time with one supplier<sup>[3](https://download.pli.edu/WebContent/pm/357816/pdf/10-12-2023_0905_141661_Handout2.pdf)</sup>. Loyalty rebates and fidelity discounts achieve the same concentration of purchases through pricing rather than contract terms, and Section 1 of the Sherman Act covers de facto and partial exclusive dealing achieved this way<sup>[3](https://download.pli.edu/WebContent/pm/357816/pdf/10-12-2023_0905_141661_Handout2.pdf)</sup>. Recent US case law extends the concept further: in *CoStar Group v. CoStar Exchange* (9th Cir. 2025) the Ninth Circuit held that technological barriers and contractual terms preventing customers from dealing with competitors constitute de facto exclusive agreements sufficient to state a claim<sup>[12](https://verdict.com/case-law/topics/national/restraint-of-trade/exclusive-dealing-substantial-foreclosure-doctrine-tc7p1w)</sup>.\n\n## How the mechanism works\n\n**Foreclosure through scale.** The core concern is that exclusive contracts restrict rivals' access to inputs, distribution, customers, or complements, raising rivals' costs and enabling the defendant to gain pricing power<sup>[13](https://antitrustcasebook.org/download/Chapter%20VI%20-%20Vertical%20Restraints.pdf)</sup>. The mechanism turns on minimum efficient scale, the smallest volume at which a firm can produce competitively. If several exclusive arrangements in a market are staggered so that only a few come up for renewal in any given year, only a small portion of demand is contestable at any time; even arrangements covering most but not all of a partner's purchases can produce substantial foreclosure because rivals cannot reach the scale they need<sup>[2](https://www.internationalcompetitionnetwork.org/wp-content/uploads/2018/07/UCWG_UCW_Ch5.pdf)</sup>. Dentsply illustrates the point: its direct-selling competitors Ivoclar and Vita held only about 5% and 3% market shares, showing that selling outside the dealer channel posed little threat<sup>[8](https://digitalcommons.law.villanova.edu/cgi/viewcontent.cgi?article=2495&context=thirdcircuit_2005)</sup>.\n\n**Divide and conquer.** Economic models sharpen the mechanism. Rasmusen, Ramseyer, and Wiley showed that with 100 customers and a minimum efficient scale of 15, a monopoly need only lock up 86 customers to forestall entry, exploiting customer disorganization so that exclusion is profitable even though each customer would be better off refusing<sup>[10](https://rasmusen.org/published/Rasmusen_91.AER.exclusion.htm)</sup>. Segal and Whinston showed the incumbent need not rely on disorganization at all: by exploiting externalities among buyers with discriminatory offers, a divide-and-conquer strategy can profitably exclude rivals; conversely, when offers must be nondiscriminatory and buyers can coordinate, exclusion never succeeds<sup>[14](https://web.stanford.edu/~isegal/comment.pdf)</sup>. In two-sided platform markets the arithmetic compounds: with loyalty contracts on both sides each covering 90% of volume, contestable demand falls to 1% of total transactions, since (1 − 0.9) × (1 − 0.9) = 1%<sup>[9](https://www.ftc.gov/enforcement/competition-matters/2026/02/how-loyalty-discounts-between-firms-harm-competition-when-there-are-network-effects-ftc-v-surescripts)</sup>.\n\n**The efficiency side.** The same contracts can solve real problems. Non-compete type restrictions help overcome free riding between suppliers and address the [hold-up problem](https://www.edgepedia.org/hold-up-problem) from relationship-specific investments such as specific equipment or training<sup>[11](https://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=intcom%3AC%282022%294238)</sup>. The FTC states that most exclusive dealing contracts are beneficial because they encourage marketing support for the manufacturer's brand, such as trained salespeople, inventory, and fast warranty service<sup>[1](https://www.ftc.gov/advice-guidance/competition-guidance/guide-antitrust-laws/dealings-supply-chain/exclusive-dealing-or-requirements-contracts)</sup>. The classic example is the 1919 GM–Fisher contract, which Klein attributed to the need to protect Fisher's investments in stamping machines and dies specific to GM's car designs<sup>[15](https://web.stanford.edu/~isegal/rje_Winter'00_Segal.pdf)</sup>.\n\n## By the numbers\n\nUS law has accumulated a set of percentage benchmarks, none of them absolute:\n\n- **30% safe harbor.** An ICN report summarized U.S. agency statements as describing a 30% safe harbor and saying that in most instances foreclosure must exceed 50% to raise competitive concern<sup>[16](https://www.internationalcompetitionnetwork.org/wp-content/uploads/2018/07/UCWG_SR_SingBrndExcDealing.pdf)</sup>. The DOJ's report recognized a safe harbor below 30% while stressing that above 30% was neither automatically nor presumptively illegal<sup>[4](https://appliedantitrust.com/20_exclusive_contracts/doj_section2_report_exclusive_dealing.pdf)</sup>.\n- **40–50% for Section 1.** In *United States v. Microsoft*, Judge Jackson held Microsoft's exclusive dealing arrangements were legal under Section 1 because they did not foreclose as much as 40% of the market; on appeal the D.C. Circuit stated in dicta that a \"40% or 50% share is usually required\" for a Section 1 violation<sup>[5](https://www.thesedonaconference.org/sites/default/files/publications/43-50%20Baker_0.pdf)</sup>.\n- **Case shares.** Standard Fashion held about 40% of the US dress-pattern market<sup>[17](https://www.wsgr.com/a/web/179/jacobson_foreclosure.pdf)</sup>; Dentsply held a 75–80% revenue share (67% on a unit basis)<sup>[18](https://www.wsgr.com/PDFSearch/AntitrustSource_may05_sher.pdf)</sup>; Surescripts held 95% and its loyalty contracts foreclosed at least 70% of each market<sup>[9](https://www.ftc.gov/enforcement/competition-matters/2026/02/how-loyalty-discounts-between-firms-harm-competition-when-there-are-network-effects-ftc-v-surescripts)</sup>.\n- **Low-end benchmarks.** Courts generally find that an arrangement foreclosing 20% or less of the relevant market presumptively does not adversely affect competition<sup>[3](https://download.pli.edu/WebContent/pm/357816/pdf/10-12-2023_0905_141661_Handout2.pdf)</sup>, and a general rule of thumb requires a market share of at least 55% to demonstrate market power<sup>[18](https://www.wsgr.com/PDFSearch/AntitrustSource_may05_sher.pdf)</sup>.\n\nTwo case figures are reported differently across sources. For Standard Stations, one account gives the individual agreement's foreclosure as 6% of the market<sup>[7](https://www.thesedonaconference.org/sites/default/files/publications/51-56%20Rosch_0.pdf)</sup> while another gives 6.7% of gasoline sales<sup>[5](https://www.thesedonaconference.org/sites/default/files/publications/43-50%20Baker_0.pdf)</sup>. For [Tampa Electric](https://www.edgepedia.org/tampa-electric), one account puts the contract at about 1% of total eastern US bituminous coal sales<sup>[17](https://www.wsgr.com/a/web/179/jacobson_foreclosure.pdf)</sup> while another gives 0.77% of the relevant market<sup>[3](https://download.pli.edu/WebContent/pm/357816/pdf/10-12-2023_0905_141661_Handout2.pdf)</sup>. Both figures make the same qualitative point: the foreclosed share was tiny.\n\n## Legal treatment: United States\n\n**Statutory bases.** Courts have condemned exclusive dealing under four provisions: Section 1 and Section 2 of the Sherman Act, Section 3 of the Clayton Act, and Section 5 of the FTC Act<sup>[4](https://appliedantitrust.com/20_exclusive_contracts/doj_section2_report_exclusive_dealing.pdf)</sup>. The Clayton Act of 1914 specifically prohibited certain exclusive dealing agreements, among other practices, reducing the judicial discretion left by the Sherman Act<sup>[19](https://ios23.classes.ryansafner.com/files/readings/Kovacic-Shapiro-2000.pdf)</sup>. Before 1914, exclusive dealing was regarded as a \"partial\" restraint and generally upheld except where it created an actual monopoly<sup>[17](https://www.wsgr.com/a/web/179/jacobson_foreclosure.pdf)</sup>.\n\n**The doctrinal arc.** In *Standard Oil Co. v. United States* (Standard Stations, 1949) the Court rejected per se treatment and held legality turns on whether competition has been foreclosed in a substantial share of the commerce affected; the individual agreement foreclosed only about 6% of the market, but the aggregate of such agreements foreclosed 65%, held sufficient for illegality under Clayton Section 3<sup>[7](https://www.thesedonaconference.org/sites/default/files/publications/51-56%20Rosch_0.pdf)</sup>. In *Tampa Electric* (1961) the Supreme Court replaced this \"quantitative substantiality\" test with a \"qualitative substantiality\" analysis considering duration, purpose, and effect<sup>[7](https://www.thesedonaconference.org/sites/default/files/publications/51-56%20Rosch_0.pdf)</sup>. The FTC's 1982 Beltone decision marked the shift toward rule-of-reason treatment, upholding exclusive dealing covering 16% of the hearing aid market, and post-Beltone decisions routinely sustained arrangements with foreclosure of 40% or less<sup>[17](https://www.wsgr.com/a/web/179/jacobson_foreclosure.pdf)</sup>. In *Barry Wright Corp. v. ITT Grinnell*, Judge Breyer upheld a purchase agreement accounting for some fifty percent of annual sales in the relevant market, citing the buyer's desire for assurance of adequate supply; since 1997 courts increasingly focus on the effect of the arrangement on the defendant's market power rather than bare foreclosure percentages<sup>[17](https://www.wsgr.com/a/web/179/jacobson_foreclosure.pdf)</sup>.\n\n**Duration and terminability.** The Seventh Circuit in *Roland Machinery* (1984, Posner) held that exclusive dealing contracts terminable in less than a year are presumptively lawful under Section 3, and required proof of exclusion of a significant competitor plus probable price-raising effects<sup>[7](https://www.thesedonaconference.org/sites/default/files/publications/51-56%20Rosch_0.pdf)</sup>. The Dentsply court distinguished such assertions, holding that exclusive dealing arrangements terminable at will can be as effective as written contracts in foreclosing competition<sup>[8](https://digitalcommons.law.villanova.edu/cgi/viewcontent.cgi?article=2495&context=thirdcircuit_2005)</sup>.\n\n**Section 2 cases.** In *Dentsply* (Third Circuit, 2005), the court held that Dentsply's refusal to sell to distributors carrying other manufacturers' artificial teeth violated Sherman Act Section 2 by unlawfully maintaining monopoly power, keeping sales of competing teeth below the critical level needed for any rival to pose a real threat; its efficiency justifications were found pretextual<sup>[4](https://appliedantitrust.com/20_exclusive_contracts/doj_section2_report_exclusive_dealing.pdf)</sup>. In 2001 the D.C. Circuit upheld condemnation of exclusivity agreements between Microsoft and OEMs, internet access providers, independent software vendors, and Apple under Section 2 because they barred rivals from means of distribution<sup>[4](https://appliedantitrust.com/20_exclusive_contracts/doj_section2_report_exclusive_dealing.pdf)</sup>. Unlike Section 1, no safe harbor exists for monopolists under Section 2<sup>[5](https://www.thesedonaconference.org/sites/default/files/publications/43-50%20Baker_0.pdf)</sup>.\n\n**Recent decisions.** In *FTC v. Surescripts*, the court ruled Surescripts held a 95% market share since 2010 in electronic prescription routing markets and has had monopoly power since that time; its web of loyalty contracts foreclosed at least 70% of each market, eliminating competitive attempts such as Emdeon's<sup>[9](https://www.ftc.gov/enforcement/competition-matters/2026/02/how-loyalty-discounts-between-firms-harm-competition-when-there-are-network-effects-ftc-v-surescripts)</sup>. In *United States v. Google LLC* (D.D.C. 2025), the court found Google's exclusive distribution agreements with browser developers, OEMs, and carriers locked up the most efficient search-distribution channels <sup>[12](https://verdict.com/case-law/topics/national/restraint-of-trade/exclusive-dealing-substantial-foreclosure-doctrine-tc7p1w)</sup>. By contrast, in *Sanofi-Aventis v. Mylan* (10th Cir. 2022) summary judgment was affirmed despite over 90% market share and long contract durations, because there was no evidence of actual consumer harm such as higher prices or reduced output<sup>[12](https://verdict.com/case-law/topics/national/restraint-of-trade/exclusive-dealing-substantial-foreclosure-doctrine-tc7p1w)</sup>.\n\n## Legal treatment: European Union\n\nThe EU addresses exclusive dealing both under Article 101 for vertical agreements and under Article 102 for dominant firms. The 2022 Vertical Guidelines state that [vertical restraints](https://www.edgepedia.org/vertical-restraints) can lead to foreclosure, softening of competition, or collusion, and that the degree of market power required for a restriction under Article 101(1) is less than that required for dominance under Article 102<sup>[11](https://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=intcom%3AC%282022%294238)</sup>.\n\n**The VBER.** Regulation (EU) 2022/720 exempts vertical agreements under Article 101(3) on condition that the supplier's and the buyer's market shares each do not exceed 30% of the relevant markets<sup>[6](https://eur-lex.europa.eu/eli/reg/2022/720/oj/eng)</sup>. The exemption of non-compete obligations is limited to obligations not exceeding a duration of five years<sup>[6](https://eur-lex.europa.eu/eli/reg/2022/720/oj/eng)</sup>, and where parallel networks of similar vertical restraints cover more than 50% of a relevant market, the Commission may declare the Regulation inapplicable<sup>[6](https://eur-lex.europa.eu/eli/reg/2022/720/oj/eng)</sup>. The Regulation entered into force on 1 June 2022, replacing Regulation 330/2010, which expired on 31 May 2022<sup>[6](https://eur-lex.europa.eu/eli/reg/2022/720/oj/eng)</sup><sup> • </sup><sup>[20](https://competition-policy.ec.europa.eu/antitrust-and-cartels/legislation/vertical-block-exemptions_en)</sup>.\n\n**Article 102 case law.** The CJEU in *Michelin II* inferred that any loyalty-inducing rebate system applied by a dominant undertaking has foreclosure effects prohibited by Article 102, creating what commentators describe as a near-irrebuttable presumption against dominant firms<sup>[21](https://repository.law.umich.edu/cgi/viewcontent.cgi?article=1134&context=law_econ_current)</sup>. In *Delimitis*, the Court articulated a two-part test for exclusive dealing-type agreements: whether the agreement foreclosed market participation by rivals, and the significance of the agreement at issue<sup>[21](https://repository.law.umich.edu/cgi/viewcontent.cgi?article=1134&context=law_econ_current)</sup>. In *Van den Bergh*, the Court of First Instance held that an undertaking with a market share of more than 75% tying outlets in the relevant market by an exclusivity clause constituted an abuse<sup>[16](https://www.internationalcompetitionnetwork.org/wp-content/uploads/2018/07/UCWG_SR_SingBrndExcDealing.pdf)</sup>. The German Bundeskartellamt found anti-competitive foreclosure in long-term gas supply contracts where 70% of customers were tied to the dominant supplier through contracts covering 100% of their respective demand<sup>[16](https://www.internationalcompetitionnetwork.org/wp-content/uploads/2018/07/UCWG_SR_SingBrndExcDealing.pdf)</sup>.\n\n**2025 developments.** On 8 May 2025, the CJEU held in *Beevers Kaas* (C-581/23) that the mere absence of active sales by non-exclusive distributors is insufficient to satisfy the block-exemption conditions for exclusive distribution; a supplier must impose a parallel active-sales ban on its other distributors, shown by an express restriction or by explicit or tacit acquiescence following the *Super Bock* \"concurrence of wills\" approach<sup>[22](https://www.ashurstperkinscoie.com/en/insights/cjeu-sharpens-stance-on-active-sales-bans-in-exclusive-distribution/)</sup>. The Commission has also adopted new Guidelines on exclusionary abuses of dominance under Article 102, dated 3 September 2026, covering exclusive dealing, loyalty rebates, tying, self-preferencing, and other conduct<sup>[23](https://competition-policy.ec.europa.eu/document/download/ac0e592e-2c8e-4a45-aae5-d82e7327b022_en?filename=Guidelines_on_exclusionary_abuses_of_dominance_102TFEU.pdf)</sup>.\n\n## How economists model exclusion\n\n**Naked exclusion.** Rasmusen, Ramseyer, and Wiley's 1991 model requires no precommitment to future prices, liquidated damages, or cost differences; entry is certain absent exclusionary tactics, yet exclusion can still be profitable<sup>[10](https://rasmusen.org/published/Rasmusen_91.AER.exclusion.htm)</sup>. Their reply states the conditions for profitable, socially inefficient exclusion: a minimum efficient scale, and customers who expect exclusion to succeed and cannot coordinate to defeat it; at a theoretical limit the excluding firm can gain exclusionary rights for free<sup>[24](https://www.rasmusen.org/published/Rasmusen_00.AER.exclusion.pdf)</sup>. They also note that the leading Supreme Court cases (Standard Stations, Tampa Electric, Jefferson Parish) violate the assumptions of the theory, so it does not support a per se ban on exclusive dealing<sup>[24](https://www.rasmusen.org/published/Rasmusen_00.AER.exclusion.pdf)</sup>.\n\n**Investment protection and its limits.** Segal and Whinston formally examined when exclusive contracts protect noncontractible relationship-specific investments, distinguishing complementary from substitutable investment effects<sup>[15](https://web.stanford.edu/~isegal/rje_Winter'00_Segal.pdf)</sup>. But when the external source's investment is an entry cost, exclusivity discourages entry, and the buyer and supplier have a socially excessive incentive to use it, as in Aghion and Bolton<sup>[15](https://web.stanford.edu/~isegal/rje_Winter'00_Segal.pdf)</sup>. A 2012 *Journal of Industrial Economics* paper shows a model in which exclusive dealing both promotes the incumbent seller's investment and can exclude a more efficient entrant, inviting a more cautious attitude toward investment-promotion defenses<sup>[25](https://onlinelibrary.wiley.com/doi/10.1111/joie.12006)</sup>.\n\n**Ambiguity and newer theories.** Bernheim and Whinston (1998) show that exclusionary contractual provisions may be irrelevant, anticompetitive, or efficiency-enhancing, depending on the setting, including anticompetitive effects in markets other than the ones in which exclusive dealing is practiced<sup>[26](https://www.journals.uchicago.edu/doi/10.1086/250003)</sup>. Calzolari and Denicolò (AER 2015) propose a theory in which a dominant firm with a competitive advantage and privately informed buyers can impose exclusive contractual restrictions without necessarily compensating buyers, making exclusive dealing both profitable and anticompetitive<sup>[27](https://ideas.repec.org/a/aea/aecrev/v105y2015i11p3321-51.html)</sup>. Calzolari, Denicolò, and Zanchettin (RAND 2020) show that with distorted prices, exclusive dealing can be directly profitable and anticompetitive when the dominant firm enjoys a competitive advantage, gaining from a demand boost when buyers sign exclusive contracts<sup>[28](https://onlinelibrary.wiley.com/doi/10.1111/1756-2171.12338)</sup>.\n\n## Loyalty rebates and other exclusivity variants\n\nLoyalty rebates and fidelity discounts reach the same result as outright exclusivity but through pricing. In Europe the contingency governing loyalty rebates is called a \"suction effect\", the heavy pressure on the buyer near the end of the contract period to continue purchasing from the original supplier<sup>[29](https://scholarship.law.umn.edu/cgi/viewcontent.cgi?article=1894&context=faculty_articles)</sup>. A scholarly account describes EU enforcement as applying an as-efficient-competitor standard to predation, loyalty rebates, and bundling<sup>[29](https://scholarship.law.umn.edu/cgi/viewcontent.cgi?article=1894&context=faculty_articles)</sup>, and *Michelin II* was read to presume that loyalty-inducing rebates by a dominant firm have foreclosure effects<sup>[21](https://repository.law.umich.edu/cgi/viewcontent.cgi?article=1134&context=law_econ_current)</sup>.\n\nUS courts have begun applying reduced thresholds to such programs. In *American President Lines v. Matson* (D.D.C. 2022), a loyalty discount program requiring a 90% volume commitment was held to be de facto exclusive dealing, with a reduced foreclosure threshold of approximately 35% because the defendant was a monopolist<sup>[12](https://verdict.com/case-law/topics/national/restraint-of-trade/exclusive-dealing-substantial-foreclosure-doctrine-tc7p1w)</sup>. In *LePage's Inc. v. 3M*, the Third Circuit saw 3M's bundle pricing as a mechanism for excluding LePage's transparent tape, achieving the results of predatory pricing without selling any item below cost<sup>[29](https://scholarship.law.umn.edu/cgi/viewcontent.cgi?article=1894&context=faculty_articles)</sup>. The FTC's Section 5 policy statement identified loyalty rebates, tying, bundling, and exclusive dealing arrangements that have the tendency to ripen into violations as exemplary violations, and as an incipiency statute Section 5 requires no showing of actual harm<sup>[30](https://download.pli.edu/WebContent/pm/357689/pdf/05-01-2023_1600_140240_Falls.pdf)</sup>.\n\n## Recent developments\n\nThree developments mark the recent shift. First, the Surescripts settlement prohibits Surescripts from using exclusivity or loyalty contracts requiring 50% or more of a customer's transactions<sup>[9](https://www.ftc.gov/enforcement/competition-matters/2026/02/how-loyalty-discounts-between-firms-harm-competition-when-there-are-network-effects-ftc-v-surescripts)</sup>. Second, the 2025 Google decision found exclusive distribution agreements locked up the most efficient search-distribution channels <sup>[12](https://verdict.com/case-law/topics/national/restraint-of-trade/exclusive-dealing-substantial-foreclosure-doctrine-tc7p1w)</sup>. Third, in the EU the *Beevers Kaas* judgment tightened the conditions for relying on the vertical block exemption for exclusive distribution<sup>[22](https://www.ashurstperkinscoie.com/en/insights/cjeu-sharpens-stance-on-active-sales-bans-in-exclusive-distribution/)</sup>, and the Commission adopted new Article 102 exclusionary-abuse Guidelines covering exclusive dealing and loyalty rebates<sup>[23](https://competition-policy.ec.europa.eu/document/download/ac0e592e-2c8e-4a45-aae5-d82e7327b022_en?filename=Guidelines_on_exclusionary_abuses_of_dominance_102TFEU.pdf)</sup>. As of 2023, other notable matters included FTC v. Syngenta and Corteva (\"pay to block\") and Qualcomm/Apple cases<sup>[30](https://download.pli.edu/WebContent/pm/357689/pdf/05-01-2023_1600_140240_Falls.pdf)</sup>.\n\n## References\n\n1.
