US Senate Blocks Crypto 'Clarity' Bill, Sending Bitcoin and Major Crypto Stocks Lower

The U.S. Senate failed to invoke cloture on the CLARITY Act by 49-50 on September 15, 11 votes short of the 60 required, with three to four Republicans joining Democrats to block it. The procedural detail matters: this was cloture on the motion to proceed, not a vote on passage, so the bill never reached floor debate or amendments. Democrats' stated condition was an enforceable bar on the president and senior officials profiting from crypto while the rules are being written; Republican ethics revisions offered over the weekend did not move enough votes. Most coverage reads the outcome as ending Senate market-structure legislation for this year.

Crypto assets and equities sold off into that result on September 15. Bitcoin slid below $76,000, touching an intraday low near $74,967.97 after opening the week close to $80,000, with ether down 3.9% to $2,407. COIN fell about 9% to $174.42 and Circle dropped 9.4% to $88.26. SentiSense's own measurement of that session puts COIN down 10.1% and MSTR down 5.4%, which corroborates the roughly 5% Strategy decline reported at the time. XRP's headline 3.79% drop covers only a roughly three-hour window around the vote; its broader move that day was closer to 9% to 11%, to about $1.28.

Attribution deserves a caveat the headlines skip. CoinDesk noted that September 15 trading was also shaped by investors cutting risk ahead of the Federal Reserve decision the following day, so the vote is one of at least two forces in the tape rather than the whole of it. Prediction markets moved more cleanly: Polymarket odds of the bill passing in 2026 fell from about 30% to the 14 to 18% range.

A caution on the apparent rebound. One widely shared article published at 08:53 ET on September 16 reported Coinbase, Strategy and Robinhood trading higher and read it as the previous day's selloff having front-run the result. That bounce did not hold. SentiSense data later in the same session shows COIN at $164.90, down 4.2%, and MSTR at $125.46, down 3.2%, so the early-morning green was a snapshot rather than a reversal in view. Analysts quoted downplaying the defeat as "nothing truly structural" may still prove right over a longer horizon, but the two sessions since the vote have gone the other way, and the near-term path likely depends more on the Fed than on any revival of the bill.
