How the Tunney Act Could Shape the Future of Crypto: Antitrust in the Blockchain Era

The Tunney Act, formally known as the Antitrust Procedures and Penalties Act of 1974 (15 U.S.C. § 16), is a U.S. federal law that governs the judicial review process for consent decrees in antitrust cases brought by the Department of Justice (DOJ).

It ensures transparency and public interest considerations in settlements between the DOJ and companies accused of violating antitrust laws, such as monopolistic practices or anti-competitive behavior.

The Act requires courts to evaluate whether proposed settlements are in the public interest before approving them, mandates public disclosure of settlement details, and allows for public comments and judicial hearings to assess the decree’s impact.

Below, I’ll explore the potential application of the Tunney Act to the cryptocurrency market, considering its structure, regulatory challenges, and antitrust concerns.

Since the Tunney Act specifically applies to DOJ antitrust settlements, its relevance to crypto depends on whether and how antitrust issues arise in this market. I’ll also address the current regulatory landscape for cryptocurrencies and how the Tunney Act could theoretically intersect with it.

1. Understanding the Tunney Act in Context
   The Tunney Act was enacted to address concerns that DOJ antitrust settlements (consent decrees) were sometimes negotiated without sufficient public scrutiny or oversight, potentially allowing powerful companies to escape meaningful accountability. Key provisions include:
   • Public Interest Review: Courts must determine if a proposed consent decree serves the public interest, considering factors like the settlement’s effectiveness in addressing competitive harm and its impact on consumers.
   • Transparency: The DOJ must publish the proposed decree, a competitive impact statement, and any related materials in the Federal Register, allowing public access.
   • Public Participation: The Act permits a 60-day public comment period and allows third parties (e.g., competitors, consumers) to submit concerns about the settlement.
   • Judicial Oversight: Courts may hold hearings to evaluate the decree, ensuring it adequately remedies the alleged antitrust violations.

   
   

   The Act applies to civil antitrust cases under laws like the Sherman Act (15 U.S.C. §§ 1-7) or Clayton Act (15 U.S.C. §§ 12-27), which address monopolies, price-fixing, market allocation, and other anti-competitive practices.

   
   

2. The Cryptocurrency Market and Antitrust Concerns
   The cryptocurrency market, encompassing digital assets like Bitcoin, Ethereum, stablecoins, and decentralized finance (DeFi) platforms, is a rapidly evolving sector with unique characteristics that could raise antitrust concerns.

   
   

   To apply the Tunney Act, we first need to identify potential antitrust issues in the crypto market that might lead to DOJ enforcement actions and subsequent consent decrees.

   
   

   Potential Antitrust Issues in the Crypto Market

   • Market Concentration in Exchanges:
   • Major centralized cryptocurrency exchanges (e.g., Binance, Coinbase, Kraken) control significant portions of trading volume, custody services, and liquidity provision. For example, Binance has historically handled over 50% of global crypto trading volume at times.
   • If an exchange engages in anti-competitive practices, such as predatory pricing, exclusive dealing (forcing users to trade only on their platform), or leveraging dominance to exclude competitors, the DOJ could investigate under the Sherman Act.
   • Example: In 2023, the DOJ and Commodity Futures Trading Commission (CFTC) took action against Binance for violations including anti-money laundering (AML) failures, but no antitrust-specific case has been prominent. However, dominance in trading could hypothetically trigger scrutiny.

   
   

   • Stablecoin Market Dominance:
   • Stablecoins like Tether (US ABOVE) and USD Coin (USDC) dominate the stablecoin market, with Tether alone accounting for over 60% of stablecoin market capitalization as of 2025. Stablecoins are critical for liquidity in crypto trading and DeFi.
   • If a stablecoin issuer colludes with exchanges or engages in practices to exclude competing stablecoins (e.g., by pressuring platforms to delist rivals), this could raise antitrust concerns under Section 1 (collusion) or Section 2 (monopolization) of the Sherman Act.

   
   

   • DeFi and Protocol Control:
   • Decentralized finance platforms- (DeFi) platforms like Uniswap or Aave operate via smart contracts, but governance is often controlled by a small group of token holders or developers. If a DeFi protocol’s governance structure enables anti-competitive behavior (e.g., excluding competitors or manipulating markets), it could attract scrutiny, though decentralization complicates enforcement.
   • The decentralized nature of DeFi makes traditional antitrust enforcement challenging, but the DOJ could target centralized entities (e.g., developers or exchanges) facilitating such practices.

   
   

   • Mining Pools and Network Dominance:
   • In proof-of-work cryptocurrencies like Bitcoin, mining pools (e.g., Foundry USA, AntPool) control significant portions of the network’s hash rate. If a small number of pools collude to manipulate transaction confirmations or exclude smaller miners, this could be construed as anti-competitive.
   • However, the global and decentralized nature of mining complicates antitrust enforcement.

   
   

   • Mergers and Acquisitions:
   • The crypto market has seen consolidation, such as FTX’s acquisition of smaller platforms (before its collapse) or Binance’s strategic partnerships. If a dominant player acquires competitors to stifle competition, the DOJ could investigate under the Clayton Act, which governs anti-competitive mergers.

   
   

   • A proposed merger between two major exchanges could trigger a DOJ review, potentially leading to a consent decree subject to the Tunney Act.

   
   

   • Collusion and Price Manipulation:
   • Crypto markets are susceptible to price manipulation schemes, such as pump-and-dump or spoofing, often coordinated by groups of traders or whales (large holders). If evidence emerges of collusion among major players to fix prices or manipulate markets, the DOJ could pursue a Sherman Act case.
   • For example, the DOJ’s National Cryptocurrency Enforcement Team (NCET), established in 2021, focuses on crypto-related crimes, including fraud, which could overlap with antitrust violations.

   
   

   Regulatory Landscape and Challenges

   
   

   The crypto market lacks a unified regulatory framework in the U.S., with oversight split among agencies:

   • SEC: Treats many crypto assets as securities, focusing on investor protection and securities fraud.
   • CFTC: Regulates cryptocurrencies as commodities under the Commodity Exchange Act, particularly for derivatives markets.
   • DOJ: Investigates criminal activity, including fraud and money laundering, via the NCET.
   • FinCEN: Enforces AML and know-your-customer (KYC) rules for crypto businesses.
   • State Regulators: States like New York (BitLicense) impose additional requirements.

   
   

   This fragmented regulation creates gaps where anti-competitive behavior could thrive, as no single agency has comprehensive authority over crypto antitrust issues. The absence of clear rules also makes it harder for the DOJ to build antitrust cases, as market definitions (e.g., whether Bitcoin competes with Ethereum) and competitive harms are ambiguous in decentralized systems.

   
   

3. Applying the Tunney Act to the Crypto Market
   To apply the Tunney Act, we must consider scenarios where the DOJ pursues an antitrust case against a crypto entity, reaches a settlement, and submits a consent decree for court approval. Below are hypothetical scenarios and how the Tunney Act would function:

   
   

   Scenario 1: Antitrust Case Against a Dominant Crypto Exchange

   • Case: The DOJ investigates a leading exchange (e.g., Binance) for monopolistic practices, such as using its market dominance to impose high fees, exclude rival exchanges, or manipulate trading volumes. Evidence shows Binance colluded with stablecoin issuers to favor its own stablecoin (e.g., BUSD) over competitors.
   • Settlement: The DOJ and Binance agree to a consent decree requiring Binance to:
   • Lower trading fees to competitive levels.
   • Cease exclusive partnerships with stablecoin issuers.
   • Allow third-party audits of its trading algorithms to ensure fairness.
   • Divest certain assets (e.g., a proprietary token) to reduce market control.
   • Tunney Act Process:
   • Publication: The DOJ publishes the consent decree and a competitive impact statement in the Federal Register, outlining how the settlement restores competition in the crypto trading market.
   • Public Comment: Competitors (e.g., Coinbase, Kraken), consumer groups, and crypto investors submit comments. Some argue the settlement is too lenient, failing to address Binance’s global dominance, while others claim it’s too harsh, risking market instability.
   • Judicial Review: A federal court holds a hearing, reviewing public comments, DOJ arguments, and Binance’s compliance plan. The court may request additional remedies, such as mandatory interoperability with rival platforms, if it finds the decree insufficient.
   • Outcome: If approved, the decree is enforced, with Binance reporting compliance to the DOJ. If rejected, the DOJ and Binance must renegotiate or proceed to trial.

   
   

   Scenario 2: Stablecoin Issuer Collusion

   
   

   • Case: The DOJ finds that two major stablecoin issuers (e.g., Tether and USDC) colluded with exchanges to delist smaller stablecoins, reducing competition and inflating their market share. This violates Section 1 of the Sherman Act (collusion).

   
   

   • Settlement: The issuers agree to:
   • Stop coordinating with exchanges on listings.
   • Fund a consumer protection program to educate investors about stablecoin risks.
   • Submit to regular audits to verify reserve backing (ensuring transparency).

   
   

   • Tunney Act Process:

   
   

   • Publication: The DOJ details how the settlement promotes fair competition and protects investors, noting stablecoins’ role in DeFi and trading.
   • Public Comment: DeFi protocols argue the settlement doesn’t address underlying reserve risks, while smaller stablecoin issuers demand stronger penalties. Public comments highlight the global nature of stablecoins, questioning U.S. jurisdiction.
   • Judicial Review: The court evaluates whether the settlement adequately deters future collusion, considering global market dynamics. It may request cross-border cooperation clauses to strengthen enforcement.
   • Outcome: An approved decree could set a precedent for stablecoin regulation, while a rejected one might push the DOJ to pursue broader legislation.

   
   

   Scenario 3: Merger of Crypto Platforms

   
   

   • Case: Two major DeFi platforms propose a merger, which the DOJ challenges under the Clayton Act, arguing it would create a near-monopoly in decentralized lending. The platforms settle by agreeing to maintain open APIs for competitors and limit governance concentration.
   • Settlement: The consent decree includes:
   • A commitment to open-source certain protocols to foster competition.
   • Restrictions on voting power for large token holders.
   • A monitoring trustee to oversee compliance.
   • Tunney Act Process:
   • Publication: The DOJ explains how the settlement preserves DeFi’s competitive landscape, crucial for innovation.
   • Public Comment: Developers and users debate whether open-sourcing protocols stifles proprietary innovation or promotes fairness. Consumer groups demand stronger consumer protections.
   • Judicial Review: The court assesses whether the decree balances innovation and competition, potentially adding requirements for user fund safeguards.
   • Outcome: An approved decree could shape DeFi governance, while a rejected one might deter future mergers.

   
   

4. Challenges in Applying the Tunney Act to Crypto

   
   

   Applying the Tunney Act to crypto antitrust cases faces unique hurdles due to the market’s structure and regulatory gaps:

   
   

   • Decentralization:
   • Many crypto entities (e.g., DeFi protocols, Bitcoin miners) lack a central authority, complicating DOJ enforcement. Identifying a defendant for an antitrust case is harder than in traditional markets.
   • Decentralized governance (e.g., DAOs) may shield actors from liability, as no single entity controls decisions.

   
   

   • Global Nature:
   • Crypto markets operate globally, with many platforms based offshore (e.g., Binance in Malta, Tether in Hong Kong). The DOJ’s jurisdiction is limited, and enforcing a consent decree abroad is challenging.
   • Public comments under the Tunney Act may highlight this, urging courts to consider international cooperation, as seen in Tunisia’s 2024 crypto laws.

   
   

   • Market Definition:
   • Antitrust cases require defining the relevant market (e.g., all cryptocurrencies, stablecoins, or DeFi lending). Crypto’s novelty makes this contentious, as Bitcoin, Ethereum, and stablecoins serve different functions.
   • Courts reviewing a consent decree may struggle to assess competitive harm if the market is undefined.

   
   

   • Rapid Evolution:
   • The crypto market evolves faster than regulatory processes. A consent decree approved in 2025 may be obsolete by 2026 if new technologies (e.g., layer-2 solutions) shift market dynamics.
   • Public comments may push for flexible decrees with periodic reviews.

   
   

   • Regulatory Fragmentation:
   • Overlapping SEC, CFTC, and state regulations create confusion. The DOJ must coordinate with other agencies, which could delay settlements and complicate Tunney Act reviews.
   • For example, the SEC’s focus on securities laws may conflict with the DOJ’s antitrust priorities.

   
   

   • Public Interest Definition:
   • The Tunney Act’s “public interest” standard is vague. In crypto, it could mean investor protection, market stability, or innovation. Courts may struggle to balance these, especially if public comments conflict.
   • For instance, consumers may prioritize low fees, while developers emphasize decentralization.

   
   

5. Current and Proposed Crypto Regulations (Context for Tunney Act)

   
   

   The crypto market’s regulatory landscape shapes how antitrust issues arise and how the Tunney Act might apply.

   
   

   Key developments include:

   • Pending Legislation:
   • The Financial Innovation and Technology for the 21st Century Act (FIT21) aims to clarify SEC and CFTC roles in crypto regulation, potentially streamlining antitrust enforcement. It passed House committee votes in 2024 and awaits a floor vote.
   • Stablecoin bills (e.g., Clarity for Payment Stablecoins Act, Lummis-Gillibrand Act) propose oversight for stablecoin issuers, which could address collusion or dominance.
   • These bills, if passed, could lead to DOJ investigations of stablecoin or exchange practices, triggering Tunney Act reviews.

   
   

   • SEC and CFTC Actions:
   • The SEC’s Crypto Task Force (2025) seeks to clarify securities laws for crypto, potentially overlapping with DOJ antitrust cases if securities violations involve anti-competitive conduct.
   • The CFTC has pursued enforcement against crypto platforms (e.g., Binance, Uniswap) for commodity-related violations, which could complement DOJ efforts.

   
   

   • State Regulations:
   • New York’s BitLicense and proposed Crypto Regulation, Protection, Transparency, and Oversight (CRPTO) Act (2023) impose strict rules on exchanges, including conflict-of-interest bans, which align with antitrust goals.
   • California’s Department of Financial Protection and Innovation takes a lighter approach, potentially creating regulatory arbitrage.

   
   

   • Global Trends:
   • The EU’s Markets in Crypto-Assets (MiCA) regulation (2025) sets a comprehensive framework, including stablecoin oversight, which could influence U.S. policy.
   • Tunisia’s 2024 crypto laws emphasize AML/KYC and consumer protection, offering a model for balancing innovation and oversight.

   
   

   These developments suggest growing momentum for crypto regulation, which could increase DOJ antitrust scrutiny and Tunney Act applications. For example, a stablecoin collusion case could arise under FIT21, with a consent decree reviewed for public interest alignment with MiCA-like standards.

   
   

6. Hypothetical Tunney Act Impact on Crypto Market

   
   

   If the Tunney Act were applied to a crypto antitrust settlement, its impact would depend on the decree’s scope and enforcement:

   
   

   • Positive Impacts:
   • Enhanced Competition: A decree forcing an exchange to lower fees or divest assets could level the playing field, benefiting smaller platforms and consumers.
   • Investor Protection: Requiring audits or transparency (e.g., for stablecoin reserves) could reduce fraud and build trust, as seen in Tunisia’s approach.
   • Innovation: By curbing monopolistic practices, the decree could encourage new entrants, fostering DeFi or blockchain innovation.
   • Public Engagement: The Tunney Act’s comment period ensures diverse voices (e.g., miners, developers, investors) shape the outcome, aligning with crypto’s ethos of decentralization.

   
   

   • Negative Impacts:
   • Regulatory Overreach: A poorly designed decree could stifle innovation, as seen with New York’s BitLicense, which drove firms offshore.
   • Market Instability: Divesting assets or restricting trading could disrupt liquidity, especially in volatile crypto markets.
   • Global Disadvantage: Strict U.S. decrees could push firms to jurisdictions with lax rules (e.g., Singapore, Malta), undermining DOJ goals.
   • Enforcement Costs: Monitoring compliance in a decentralized, global market is resource-intensive, potentially weakening the decree’s impact.

   
   

   • Long-Term Effects:
   • A successful Tunney Act review could set precedents for crypto antitrust, clarifying market definitions and competitive standards.
   • It could push Congress to pass FIT21 or similar laws, reducing reliance on ad hoc DOJ settlements.
   • Globally, U.S. decrees could influence regulators in the EU or Asia, creating harmonized standards, as Tunisia aims to do.

   
   

7. Critical Analysis: Is the Tunney Act Fit for Crypto?

   
   

   The Tunney Act is a robust tool for ensuring antitrust settlements serve the public interest, but its application to crypto reveals limitations:

   
   

   • Strengths:
   • Transparency: Public disclosure and comments align with crypto’s open-source ethos, ensuring accountability.
   • Flexibility: Courts can tailor decrees to crypto’s unique features, unlike rigid securities laws.
   • Precedent-Setting: Successful decrees could guide future crypto regulation, filling gaps left by Congress.

   
   

   • Weaknesses:
   • Outdated Framework: The Tunney Act, designed for traditional industries, struggles with crypto’s decentralization and global scope.
   • Slow Process: The 60-day comment period and judicial review are too slow for crypto’s fast-moving market.
   • Jurisdictional Limits: The Act can’t address offshore entities, a major issue in crypto.
   • Ambiguity: The “public interest” standard is subjective, and crypto’s diverse stakeholders (miners, traders, developers) may disagree on priorities.

   
   

   • Alternative Approaches:
   • Legislation: Passing FIT21 or a dedicated crypto antitrust law could reduce reliance on Tunney Act reviews by setting clear rules.
   • International Cooperation: The DOJ could partner with global regulators (e.g., EU’s MiCA framework) to enforce decrees, as Tunisia does.
   • Sandbox Regulation: A regulatory sandbox, like Nevada’s for emerging tech, could test crypto business models before antitrust scrutiny.
   • Industry Self-Regulation: Crypto trade groups (e.g., Japan’s JVCEA) could develop voluntary codes to preempt DOJ action, though enforcement is weak.

   
   

   Critically, the Tunney Act assumes a centralized market with clear defendants, which doesn’t fully map onto crypto’s decentralized reality. For example, suing a DAO for anti-competitive governance is nearly impossible under current law. The Act’s judicial focus also risks overemphasizing consumer harm (e.g., high fees) over crypto’s broader goals, like financial inclusion or censorship resistance. A hybrid approach—combining Tunney Act reviews with new legislation and global coordination—would better suit the crypto market.

   
   

8. Conclusion

   
   

   The Tunney Act could apply to the cryptocurrency market in cases where the DOJ settles antitrust violations involving exchanges, stablecoin issuers, DeFi platforms, or other entities engaging in monopolistic or collusive practices. The Act’s process—publication, public comments, and judicial review—would ensure settlements align with the public interest, potentially enhancing competition, protecting investors, and fostering innovation. However, crypto’s decentralized, global, and fast-evolving nature poses challenges, including jurisdictional limits, market definition disputes, and regulatory fragmentation.

   
   

   Hypothetical scenarios, like a Binance monopoly case or stablecoin collusion, show how the Tunney Act could shape the market, but its effectiveness depends on clear market definitions and enforceable decrees. Current regulatory efforts (e.g., FIT21, SEC Task Force) and global trends (e.g., MiCA, Tunisia’s laws) suggest growing scrutiny of crypto, increasing the likelihood of DOJ antitrust actions and Tunney Act reviews.

   
   

   For the Act to work effectively, it must adapt to crypto’s unique features, possibly through new legislation or international partnerships. Without such adaptations, Tunney Act reviews risk being too slow, U.S.- Limited liability companies (LLCs) are not typically subject to antitrust laws directly, but their activities could still trigger DOJ scrutiny if they engage in anti-competitive practices. The crypto market’s future hinges on balancing regulation with innovation, and the Tunney Act could play a role—if it evolves with the times.

   
   

9. Recommendations for Further Research

   
   

   To deepen understanding of the Tunney Act’s application to crypto:

   • Analyze Past Tunney Act Cases: Study DOJ consent decrees in tech (e.g., Microsoft, Google) to draw parallels with crypto.
   • Track FIT21 and Stablecoin Bills: Monitor legislative progress to assess impacts on DOJ enforcement.
   • Study Global Crypto Laws: Compare U.S. antitrust approaches with the EU’s MiCA or Tunisia’s framework.
   • Examine DeFi Governance: Investigate how DAOs could face antitrust scrutiny and whether the Tunney Act applies.
   • Engage Crypto Communities: Gather insights from X posts or forums to understand stakeholder views on regulation.

   
   

   By combining legal analysis, regulatory trends, and community input, researchers can better predict how the Tunney Act might shape the crypto market’s future.
