On Sept. 15 the U.S. Senate failed to advance the CLARITY Act (cloture 49–50; 60 votes required), sending crypto markets lower: Coinbase plunged about 9–10% to close $172.11 (intraday low $168.07), Circle and related stocks fell ~9%, and Bitcoin dropped ~4% to roughly $75,900. The bill’s defeat stalls a unified regulatory framework for exchanges, DeFi and token markets, leaving firms subject to SEC/CFTC enforcement, amplifying regulatory risk after heavy industry lobbying and >$65M in ARK-related selloffs that could weigh on adoption, fundraising and token/stock performance.

Key Insights
- Coinbase stock fell about 9% after the U.S. Senate failed to advance the CLARITY Act in Tuesday’s procedural vote.
- The CLARITY Act stalled in the Senate, putting a proposed U.S. crypto regulatory framework on hold after lawmakers failed to clear the measure.
- Crypto markets also weakened: Bitcoin fell about 4% to $75,908, while Coinbase and Circle shares each dropped roughly 9%.
- The setback comes after months of lobbying and negotiations, with the crypto industry seeking clearer rules for digital assets ahead of the upcoming U.S. midterm election period.
Coinbase stock fell 10.10% on Sept. 15 after the U.S. Senate failed to advance the CLARITY Act. COIN closed at $172.11 after trading as low as $168.07 during the session.
The selloff followed a 49-50 vote on cloture for the motion to proceed to H.R. 3633. The bill needed 60 votes to advance toward formal Senate debate
Coinbase Stock Dives on CLARITY Act Setback
Investors had pinned hopes on the CLARITY Act to provide clear rules for crypto markets. The bill was backed by industry and the White House and promised a unified framework for exchanges and DeFi platforms.
With the act’s collapse, Coinbase stock wasroughly 9% lower on the day. Without a new law, crypto firms must rely on existing SEC and CFTC rules, which many worry are less predictable and more enforcement‑driven.
Analysts point out that the industry spent “hundreds of millions” lobbying for the CLARITY Act, and its defeat is seen as a major blow to digital‑asset companies.
Crypto Market Falls With Coinbase Stock
The CLARITY Act’s failure reverberated across crypto markets. Coinbase stock isn’t alone: stablecoin issuer Circle also saw its stock fall roughly 9%.
Bitcoin dipped to about $75,900, its lowest level since early August. Traders had expected the Senate to pass the bill, so the narrow loss surprised many.
With no new law, experts say regulatory risks loom larger: “Without legislation, regulations will be vulnerable to the shifting political climate and court challenges,” one analysis noted.
In short, Coinbase stock is suffering as investors reassess the outlook for U.S. crypto policy. The next catalyst on the calendar is tomorrow’s Federal Reserve meeting, but the CLARITY Act vote has clearly rattled market sentiment.
Coinbase CEO Brian Armstrong Backed CLARITY Act
For context, Coinbase CEO Brian Armstrong had publicly backed the CLARITY Act. In late August, he praised the bill, saying it would provide “consumer protection and benefits for banks, law enforcement, and crypto companies.”
Armstrong argued clearer rules would address concerns of Americans “who felt left out” by prior crypto policy and boost jobs and growth.
His support underscored Coinbase’s view that the Act would create a better environment for the industry.
Now that the legislation has stalled, those anticipated benefits are on hold, a development that likely contributed to the sharp fall in Coinbase stock.
Prior to the vote, Cathie Wood’s Ark Invest sold more than $65 million in crypto-related holdings on Monday, cutting its positions in Coinbase, Circle, Bitmine, Bullish, and the ARK 21Shares Bitcoin ETF (ARKB).
Ark sold 36,628 Coinbase stocks worth about $7 million after COIN climbed 9.24% to $191.45. The firm also sold 142,350 Circle shares, worth about $13.8 million, while Circle gained 7.53% to $97.42. Other sales included 153,881 Bitmine shares worth $3.96 million and 18,280 Bullish shares worth $687,693.
