Bitcoin gave back nearly all of Monday’s rally on Tuesday, sliding 1.7 percent to around 76,400 USD as betting markets slashed the odds of the Clarity Act becoming law this year. The largest cryptocurrency touched 79,427 USD on Monday before sentiment flipped, and it now sits roughly 7 percent below the monthly high of 82,284 USD set on September 4.

The Hook: Politics Moved the Price
If you woke up wondering why your Bitcoin position is smaller than yesterday, the answer is sitting in Washington. The U.S. Senate is scheduled to hold a key procedural vote at 2:15 p.m. ET on the Clarity Act, the market structure bill that would finally decide who regulates crypto in America. As negotiations stalled, prediction market Polymarket cut the odds of the bill becoming law this year from 34 percent on Monday to just 17 percent — and Bitcoin followed the odds down almost tick for tick.
The sticking point is not the crypto rules themselves. It is the ethics language covering what financial assets officials can hold while regulating the industry. Senate Democrats sent a counterproposal late Monday after rejecting a Republican draft that negotiators had billed as a final offer, and Republicans showed no interest in the new terms. Traders read the standoff as a sign the vote will fail.
The Market Evidence: Selling Was Near Universal
This was not a Bitcoin-only selloff. 92 of the 100 largest cryptocurrencies fell on the day, and the CoinDesk 100 index dropped 1.6 percent. Ethereum slipped 1.6 percent to about 2,420 USD, while Solana lost 2 percent to trade near 99 USD. Only a handful of tokens bucked the trend — Stellar’s XLM actually gained 4 percent as traders piled into it ahead of the vote.
- Bitcoin — down 1.7 percent to roughly 76,400 USD, after touching 79,427 USD on Monday
- Polymarket odds — Clarity Act becoming law this year fell from 34 percent to 17 percent overnight
- Futures open interest — total crypto futures interest slipped 1 percent to 135 billion USD, showing leveraged bets being unwound
- Trading volume — surged 54 percent to 207 billion USD in 24 hours as positions changed hands fast
- Bitcoin futures open interest — sitting below 680,000 BTC, a sign that demand for leveraged exposure is weak
Here is what those numbers mean in plain English: people are closing bets, not opening new ones. When open interest falls while volume spikes, existing traders are getting out faster than newcomers are getting in. That is usually a sign of caution, not panic.
The Core Conflict: Crypto Sold Off While Stocks Rallied
The most telling detail of the day is what crypto did while everything else went up. Nasdaq 100 futures gained 0.43 percent and S&P 500 futures added 0.35 percent as Monday’s AI-driven tech selloff reversed. The U.S. Dollar Index edged up only 0.17 percent. In other words, there was no broad risk-off wave sweeping markets — Tuesday’s decline was a crypto-specific reaction to the Senate standoff.
That matters for holders because it tells you what the real driver is. This is not a macro story about interest rates or recessions. It is a single binary event: either the Clarity Act advances toward becoming the first comprehensive U.S. crypto rulebook, or the legislation likely gets shelved until after the November midterm elections. Analysts at Marex noted that Bitcoin’s overnight pullback to 77,000 USD was marked by taker selling in the futures market — traders hitting the sell button at market prices rather than waiting patiently.
What Happens Next
The interesting wrinkle is that options traders are not bracing for chaos. Bitcoin’s 30-day implied volatility index ticked higher but remains well below the peaks seen in February and June. On Deribit, the largest crypto options exchange, higher-strike call options dominated the top volume ranks for both Bitcoin and Ethereum — meaning plenty of traders are still betting on upside if the vote surprises to the positive side. Funding rates on futures remain mostly positive for Bitcoin, suggesting the market leans long, though a failed vote could force leveraged shorts to cover in the opposite direction.
A short squeeze is worth explaining: when traders who bet against an asset are forced to buy it back to close their positions, the price can jump suddenly. Several analysts pointed out that a surprise yes vote on Tuesday could trigger exactly that dynamic, since positioning had shifted bearish going into the session.
The Verdict: One Vote, Two Very Different Tuesdays
For regular investors, the playbook is simple. If the cloture vote passes, the path opens to the first real U.S. crypto rulebook — historically the kind of regulatory clarity that draws institutional money in. If it fails, the Clarity Act is likely dead for this session and crypto markets may have to wait until after the November midterms for another shot, though Coinbase CEO Brian Armstrong has argued that a failed bill will not stop regulatory progress at the SEC and CFTC. Either way, the 2:15 p.m. ET vote is the moment to watch. Until then, expect Bitcoin to keep trading like a political poll with a price tag attached.

touched 79,427 yesterday and now we’re back at 76,400. classic sept, every bounce gets sold within 24h
Politicians tanked a 3,000 dollar move with one vote rescheduling. The market is entirely hostage to the Senate calendar right now.
wait so odds of the act passing halved and btc only dropped 1.7%? thats honestly bullish resilience imo
3.7% off the monthly high of 82,284 and people are acting like its capitulation. we were at 75k two weeks ago lol
btc dumping because senators cant agree on ethics language of all things. polymarket odds went 34 to 17 percent in a day, chart traders are basically just political bettors now
political bettors is exactly right. watch the 77k level, if it doesnt hold the polymarket odds basically become the chart
Traded around the Clarity Act noise all day and the XLM pump is the part that made no sense to me. 92 of the top 100 tokens bleed and that one does plus 4?
