Bitcoin traders have circled September before for earnings season or a Fed decision. This year they have two catalysts landing in the same three-week window: a Senate floor vote on the CLARITY Act and a Federal Open Market Committee meeting whose outcome traders currently peg as close to a coin flip.
The Digital Asset Market Clarity Act has already cleared the House and a Senate Banking Committee markup by a 15-9 vote, but it stalled without a floor vote or a cloture motion over the summer. Senate Majority Leader John Thune confirmed there would be no vote in August, pushing the fight into September when the chamber returns from recess on the 14th. Prediction markets have reflected the uncertainty: odds on Polymarket for passage peaked near 58% before sinking below 20% as the timeline slipped.
That whiplash matters because the bill is the crypto industry’s best remaining shot at a federal market-structure framework this year, and Wall Street heavyweights including BlackRock and Fidelity have publicly backed it. A failed or further-delayed vote would leave exchanges and token issuers operating under the same patchwork of state rules and SEC enforcement actions they have navigated for years.
September’s Uneven Track Record
Seasonality adds its own pressure. Bitcoin’s average return in September sits at just 3.08%, making it historically the third-weakest month of the year for the asset. The one consolation for bulls is recency: Bitcoin has not closed a September in the red since the 2022 bear market, when the collapse of Terra and Three Arrows Capital was still working through the market.
The Fed Adds a Second Variable
Layered on top of the legislative calendar is a Federal Reserve decision landing in the same window. Markets are currently pricing close to a 50-50 split between a rate hike and a rate cut at the upcoming FOMC meeting, a level of uncertainty that CME’s FedWatch tool shows can swing sharply in the weeks before a meeting as fresh inflation data arrives. A dovish surprise would hand risk assets a tailwind just as the CLARITY Act reaches the floor; a hawkish one would compound the legislative uncertainty.

Grayscale’s Cold Water
Not everyone is treating the bill as a market-moving event on its own. Grayscale has characterized the CLARITY Act as a “legal clarification” rather than a growth catalyst, arguing that crypto’s expansion into real-world-asset markets is already happening regardless of Congress’s timeline. That reading lines up with how corporate treasuries have kept accumulating through the uncertainty — Strategy’s CEO recently said the company plans to resume Bitcoin purchases this year, a bet that regulatory clarity, whenever it lands, only strengthens the asset’s institutional case.
For now, the Crypto Fear and Greed Index has yet to reach the euphoric readings typical of a strong bull run, even with total crypto market capitalization at $2.28 trillion and Bitcoin’s share of it holding above 56%. Traders looking for a clean signal will have to wait for both the Senate and the Fed to actually act.
