Prediction markets are sending a warning signal to the crypto sector. The Polymarket contract on the CLARITY Act has plunged from 82% in February to just 13% probability of passage in 2026 — a collapse that reshuffles the deck for traders who had positioned regulatory clarity as the next major catalyst.

Meanwhile, Bitcoin is trading below $79,000, trapped between a weakened support level and a resistance zone the market has failed to reclaim since July. The US legislative calendar has, almost by default, become the primary driver of short-term market sentiment.

Here is a breakdown of a probability gap that reveals a great deal about the true state of crypto regulation in the United States.

The CLARITY Act Hits the Senate Wall: What Prediction Markets Are Really Saying

The bill H.R. 3633 — known as the CLARITY Act — aims to grant the CFTC exclusive authority over spot markets for digital commodities, while leaving the SEC to oversee tokens classified as securities and exchange surveillance. On paper, it is exactly the framework the crypto industry has been demanding for years. In practice, the legislative path has proven far steeper than anticipated.

The Senate is set to vote on a cloture motion on September 15. Republicans hold 53 seats, but the 60-vote threshold required means convincing at least seven Democratic senators to cross the aisle. That is precisely the bet that prediction markets are increasingly pricing as unlikely.

On Polymarket, the dedicated contract — which has generated over $11.5 million in volume — now shows 13 to 14% probability of passage in 2026. By comparison, Kalshi puts the odds of a vote taking place before October 1 at 91%. That is where the real trade lies: the gaping spread between “a vote happens” and “the bill actually passes.”

Brian Armstrong, CEO of Coinbase, has publicly stated he is “fairly optimistic” about clearing the 60-vote hurdle. But prediction markets are telling a far colder story — and historically, they have proven more accurate at anticipating legislative outcomes than the stated intentions of industry stakeholders.

Bitcoin Below $79K: How Regulatory Uncertainty Is Compressing Risk Appetite

Bitcoin is trading around $78,646, down 0.28% over the past 24 hours. A seemingly minor move, but one that fits squarely within a broader compression of risk appetite directly tied to regulatory uncertainty. The $76,000 to $78,000 range has been acting as short-term support across several consecutive sessions.

Should that floor break, technical analysts are pointing to a likely retest of the low $70,000s. To the upside, resistance is concentrated between $82,000 and $84,000 — a level BTC has not convincingly reclaimed since momentum around the CLARITY Act began deteriorating in July.

Three scenarios are now structuring trader positioning:

• Bullish scenario: A surprise bipartisan breakthrough or a favorable schedule delay pushes odds back above 30%, and BTC tests $84K.
• Base scenario: Consolidation around current levels as the Senate timeline drags on without a clear resolution.
• Bearish scenario: The September 15 cloture vote fails, Polymarket odds fall into single-digit territory, and BTC retests support below $76K.

The September 15 vote remains the only short-term catalyst capable of moving the needle in any meaningful way. In a market that is watching Washington more closely than price charts, the date to watch is not a halving or a Fed decision — it is a procedural vote in the US Senate.
