US Senate Vote on CLARITY Act Leaves Crypto Markets on Edge

The US Senate is set to vote on the Digital Asset Market Clarity Act of 2025, also known as the CLARITY Act. The bill aims to clarify authority over digital assets between the SEC and CFTC, with the House-passed version giving the CFTC authority over digital-commodity transactions.

However, Republicans reportedly rejected a Democratic counteroffer before the Senate's procedural vote on September 15th. Bitcoin (BTC) fell by 0.79% in the hour following the report, while Ether (ETH) declined by 1.36%. The decline suggests that legislative uncertainty still affects short-term sentiment.

Analysts predict a close vote, with Tim Sun estimating a probability of success around 50%. Cloture would limit further debate on the motion but would not enact the CLARITY Act or immediately create new SEC and CFTC rules. The Senate would need to approve the motion before beginning formal consideration.

Assets likely to react first include BTC, ETH, Solana (SOL), XRP, UNI, and AAVE. These assets offer different forms of exposure to regulatory questions addressed by the bill. Bitcoin may lag some other tokens because its regulatory position is already established, while Ether provides infrastructure for stablecoins and decentralized finance.
