Analysis
Prediction markets moved sharply on the odds of the Clarity Act becoming law this year after Senate Republicans released a revised draft including more than 120 changes, most notably new ethics restrictions the Trump administration agreed to accept, Fortune reported. On Kalshi, the probability of the bill becoming law before October 1 briefly climbed to about 64% before settling around 53%; on Polymarket, odds rose to 30% from 14% earlier in the month.
The Digital Asset Market Clarity Act -- Clarity, for short -- would establish the primary federal framework for regulating digital-asset markets, resolving years of jurisdictional ambiguity between the SEC and CFTC over which agency actually oversees which category of crypto asset. It passed the House last year but has repeatedly stalled in the Senate, where Republicans need 60 votes and therefore at least seven Democratic votes to clear the chamber's procedural threshold.
The new ethics language is the specific concession that moved odds: the revised draft would permanently bar the president, vice president, members of Congress, federal judges and incoming elected officials -- along with their spouses -- from creating or sponsoring digital assets in exchange for payment. That provision exists because of Trump's own crypto entanglements: his financial disclosure showed more than $1.4 billion in crypto-related income in 2025, tied to ventures including World Liberty Financial, the USD1 stablecoin and the TRUMP memecoin, and Democratic holdouts had cited those conflicts as a core reason for withholding support on a bill regulating an industry the president personally profits from.
The text arrived less than 48 hours before the Senate's pivotal procedural vote, scheduled for September 15 -- a compressed timeline that leaves little room for further negotiation if the current draft doesn't hold enough Democratic support. Polymarket's more conservative 30% probability against Kalshi's 53% reflects genuinely different market structures and participant bases between the two platforms rather than a clean read on the bill's actual odds; treating either number as a precise probability rather than a directional signal overstates what prediction markets can tell you about a single procedural vote.
For venture investors and crypto-adjacent portfolio companies, Clarity passing would resolve a multi-year overhang: regulatory ambiguity over which federal agency has jurisdiction has been cited repeatedly by crypto founders and their counsel as a reason for delayed product launches and conservative go-to-market decisions in the US specifically. A defined framework, even an imperfect one, tends to unlock capital and product velocity that pure uncertainty suppresses -- a dynamic seen after prior regulatory clarity events in other sectors.
Even a successful cloture vote on September 15 only advances the bill procedurally -- it would still need to pass a final Senate vote, get reconciled with the House-passed version, and be signed into law, each a separate point of potential failure. The ethics provisions, while addressing the most visible conflict-of-interest objection, don't resolve every substantive disagreement between the House and Senate versions on market-structure details that crypto industry lobbyists have fought over for years.
The September 15 cloture vote itself is the immediate, concrete signal: whether Senate Republicans actually secure seven or more Democratic votes on the current ethics language will show whether this specific concession was enough, or whether Democratic holdouts still see gaps in the president's conflicts that this draft doesn't close.
