Polymarket traders have dramatically reduced the CLARITY Act's chances of becoming law, with odds falling below 20% as the September 15 Senate vote approaches. According to American Banker, the odds had declined from a high of 82% on February 19, reflecting months of uncertainty over whether the Senate can advance the crypto market-structure legislation. Galaxy Digital slashed its own estimate to just 10% on August 14, marking a dramatic collapse from the 82% consensus in February. The decline follows the Senate's confirmation on August 6 that it would not vote on the 309-page market structure bill before the August 7 recess, with Senate Majority Leader Thune scheduling a vote for September 15 before lawmakers left town. American Banker described September 30 as the last clear deadline before Congress turns more fully toward campaigns and partisanship, making the upcoming vote critical for the bill's prospects.
The House passed its version of the CLARITY Act by a 294-134 vote in July 2025, with 78 Democrats supporting the measure. The Senate Banking Committee later advanced its version by a 15-9 vote in May 2026, but the proposal has not received a floor vote. Senate Majority Leader John Thune filed cloture on August 8, with the motion ripening on September 15, as reported by American Banker. The Senate is scheduled to return on September 14, leaving a limited period before government funding negotiations and the midterm election calendar consume floor time. Under Senate rules, supporters need 60 votes to overcome a filibuster and begin final consideration, with Republicans holding 53 seats meaning the proposal requires at least eight Democrats to cross over - a challenge given that only two Democrats voted yes in committee. Galaxy Digital cited the Senate calendar as the primary reason for cutting odds to 10%, noting that even with bipartisan goodwill, the procedural mechanics of the Senate do not support passing a bill of this complexity in the available window.
Three unresolved disputes have stalled the bill's progress since emerging from the Senate Banking Committee in January 2026. The stablecoin yield fight centers on Coinbase's $1.35 billion annual USDC rewards revenue, with the current draft prohibiting interest on idle stablecoin balances while permitting activity-based rewards through DeFi mechanisms. Coinbase has lobbied intensely to modify the provision, arguing that prohibiting yield on idle balances while permitting it through DeFi creates an arbitrary distinction that pushes activity toward less regulated protocols. The banking lobby supports the prohibition, viewing stablecoin yield as a deposit product offered without deposit insurance, capital requirements, or FDIC oversight. The DeFi classification problem involves defining when a blockchain network is sufficiently decentralized that its tokens are no longer securities, with Democrats arguing the current criteria are too permissive - Senator Sherrod Brown's staff contended that under the proposed standards, FTX's FTT token would have qualified for commodity treatment within 18 months of launch despite Sam Bankman-Fried's centralized control. The most politically toxic dispute involves President Trump's $1.4 billion in crypto-related income, with Democrats demanding enforceable divestiture or blind trust requirements for senior officials as a condition for supporting cloture. The Trump administration complicated matters further on August 14 when the Office of the Comptroller of the Currency granted World Liberty Financial a conditional national trust bank charter, allowing the firm to issue stablecoins directly - a move Senator Warren called "the most brazen act of self dealing our financial system has ever seen."
The cryptocurrency industry has invested heavily in shaping U.S. policy, spending over $100 million during the 2024 election cycle to support candidates viewed as favorable toward digital assets. According to CryptoCurrencyWire, industry groups seeking lawmakers willing to advance measures such as the GENIUS Act and the Clarity Act have made significant political contributions. However, the legislation has drawn opposition from parts of the banking sector, with banks challenging provisions that could allow crypto companies to compete more directly for deposits by offering incentives tied to customers' stablecoin holdings. The cryptocurrency industry, including companies like Canaan Inc. (NASDAQ: CAN), seeks a clear regulatory system that firms can refer to when making their future plans before committing investment capital. Even if the Senate approves an amended measure, Congress would have more work to complete, with the House needing to accept the Senate text or both chambers requiring reconciliation before sending a final bill to Trump for his signature. The SEC and CFTC are now racing to fill the regulatory void with agency rulemaking, including the SEC's Regulation Crypto package covering token launch exemptions, decentralization safe harbors, and broker dealer custody - rules that can be reversed by a future administration unlike statutory legislation.
The CLARITY Act would establish federal rules governing digital assets and clarify the responsibilities of regulators, with the bill placing digital commodity spot markets under the CFTC while leaving assets classified as securities within the SEC's jurisdiction. For U.S. investors and crypto companies, the legislation would determine which regulator oversees different types of tokens, exchanges, brokers, and dealers. If enacted, the Clarity Act would establish a federal framework for digital-asset markets and draw a clearer line between assets regulated by the Securities and Exchange Commission and those overseen by the Commodity Futures Trading Commission. Supporters argue that clearer statutory rules would reduce regulatory uncertainty and bring crypto activity onshore, providing durable rules rather than leaving the industry to operate under agency guidance. The sub-20% Polymarket reading reflects skepticism about whether the Senate can resolve outstanding issues and move the bill forward this year, with the bill's House passage, Senate committee approval, and scheduled September vote showing it remains active but facing significant challenges. The prediction market has been consistently ahead of media coverage and industry commentary, with Polymarket's contract on 2026 passage tracking every major development with precision that traditional polling has not matched.
