CLARITY Act Odds Surge as Senate Vote Tests Crypto Bill
Prediction markets are becoming more optimistic that the CLARITY Act, a US crypto market structure bill, will become law. On Polymarket, the probability of passage this year rose from 12% in early September to nearly 30% on Monday, its highest level since early August. Kalshi showed stronger gains: the probability of passage by October 2027 rose from 26% to 53%, while the odds of passage before July increased from 30% to 53%. The probability of passage before April climbed from 23% to 45%, briefly reaching higher levels during trading.
The optimism followed the release of a final Republican Senate proposal containing new ethics provisions. However, TD Cowen analyst Jaret Sieberg kept his estimated probability of passage at 25%. He questioned whether the ethics measures would satisfy moderate Democrats, citing concerns about Donald Trump’s crypto holdings, limited state attorneys general enforcement powers and the potential political benefit to Trump before the November election.
The proposal could still attract Democratic support by providing stablecoin protections for bank deposit accounts. The first major test is Tuesday’s Senate procedural vote, which requires 60 votes and bipartisan backing. Even if successful, the CLARITY Act would still face Senate amendments, negotiations with the House and presidential approval. Traders should treat the prediction-market rally as a sentiment indicator rather than confirmation of enactment.
Bullish
The immediate market impact is cautiously bullish because rising prediction-market odds signal improving expectations for clearer US crypto regulation. A successful 60-vote procedural motion could strengthen sentiment toward digital-asset platforms, stablecoin issuers and other businesses that have faced regulatory uncertainty. Traders may respond through short-term buying, higher crypto-related equity valuations and increased positioning in assets exposed to US policy developments.
However, the signal is not confirmation that the CLARITY Act will become law. Polymarket’s probability remains below 30%, and analyst Jaret Sieberg estimates only a 25% chance of passage. The Senate vote requires bipartisan support, while amendments, House negotiations and presidential approval remain ahead. If the vote fails or Democrats reject the ethics provisions, prediction-market odds could reverse quickly and trigger a risk-off reaction in crypto markets.
Historically, crypto markets often rally on regulatory milestones but give back gains when legislation is delayed or diluted. In the short term, traders should monitor the vote result, changes in prediction-market pricing, stablecoin-related assets and broader Bitcoin market momentum. In the long term, enactment of the CLARITY Act could reduce compliance uncertainty, support institutional participation and improve market structure. Until the bill clears each legislative stage, the bullish effect is likely to remain sentiment-driven and vulnerable to political headlines.
