Clarity Act odds just did something worth stopping on. On August 19, President Trump stood in front of a room of crypto and finance executives at the White House and asked Congress to pass "a fair version of the Clarity Act." The very next afternoon, August 20, the CFTC's brand-new Innovation Advisory Committee convenes its first meeting, with crypto assets and prediction markets on the agenda. Pro-passage news cycles do not get much louder than that. And Kalshi traders responded by marking the bill more likely to pass, and later to pass, at the same time. The back half of the ladder jumped. The October rung, the nearest one the September vote can actually reach, slipped. That combination is not a contradiction, and it is not a glitch. What you are watching is the market read a calendar most of the headlines skipped, and the tell is hiding in the cheapest rung still worth arguing about. I will get to it.
The Quick Answer
Kalshi prices the Clarity Act at 22 cents to become law before 2027, 41 cents before July 2027, and 50 cents, a true coin flip, before 2028 (as of August 20, 2026). The September 15 Senate vote everyone is circling is a cloture vote on the motion to proceed. It decides whether the bill gets floor time, not whether it becomes law. The full ladder, what that vote actually unlocks, and the one rung that moved the "wrong" way are all below.

What Just Happened
Three dates stack up to explain the repricing.
On August 8, Senate Majority Leader John Thune filed cloture on the motion to proceed to the Clarity Act before the chamber left for its August recess. That set the first procedural vote for 2:15 p.m. ET on Tuesday, September 15, the day after the Senate reconvenes.
Eleven days later, on August 19, Trump pushed Congress to move on the bill at a White House gathering that included executives from Coinbase, Ripple, Robinhood, and Kraken, with SEC Chair Paul Atkins and CFTC Chair Michael Selig in the room. "Now we need Congress to take the next step by passing the Clarity Act, a fair version of the Clarity Act," he said, without specifying which provisions make a version fair.
And on the afternoon of August 20, the CFTC's Innovation Advisory Committee convenes its first meeting, scheduled for 1:00 to 4:00 p.m. ET with an agenda built around crypto assets, artificial intelligence, and prediction markets, including what the agency can do by rule while Congress works.
Presidential pressure, a scheduled vote, and a regulator visibly preparing for the aftermath. If you only read those three items, you would expect every rung of the passage ladder to rise together. They did not, and the reason lives in what September 15 actually is.
What The September 15 Vote Actually Decides
The September 15 vote is cloture on the motion to proceed. In plain terms, the Senate is voting on whether to stop debating whether to start debating the bill. It takes 60 votes. Republicans hold 53 seats, so even a unanimous GOP needs at least seven Democrats or independents to cross over.
Here is what winning that vote does not do: it does not pass the Clarity Act, it does not amend it, and it does not even begin debate on the bill's text. It clears one procedural gate out of several. After it, the Senate still faces the motion to proceed itself, floor debate, an amendment fight over the provisions that have stalled negotiations for a year (ethics rules around officials profiting from crypto, illicit-finance and anti-money-laundering language, the DeFi carve-outs), a second cloture vote on the bill itself with its own 60-vote bar, and then final passage, which needs only a simple majority. Then whatever passes has to be reconciled with the version the House approved in July 2025, because the Senate has been writing its own text, not rubber-stamping the House's.
Losing the vote is not fatal either. A failed cloture vote can be rerun; Thune can bring it back whenever the whip count improves. That asymmetry, where the vote can advance the bill but cannot kill it, is exactly why the market treats September 15 as a checkpoint rather than a verdict.

The Full Kalshi Ladder
All prices are the last trade on Kalshi's KXCRYPTOSTRUCTURE ladder as of August 20, 2026, with the move since the pre-announcement close alongside.
| Becomes Law Before | Price | Bid/Ask | Move |
|---|---|---|---|
| Sep 1, 2026 | 1¢ | 0/1 | — |
| Oct 1, 2026 | 8¢ | 7/8 | down from 9¢ |
| Nov 1, 2026 | 16¢ | 15/16 | up from 13¢ |
| Dec 1, 2026 | 20¢ | 19/20 | up from 18¢ |
| Jan 1, 2027 | 22¢ | 21/22 | — |
| Apr 1, 2027 | 34¢ | 33/35 | — |
| Jul 1, 2027 | 41¢ | 39/41 | up from 33¢ |
| Oct 1, 2027 | 46¢ | 44/46 | up from 41¢ |
| Jan 1, 2028 | 50¢ | 48/50 | up from 44¢ |
The row I keep coming back to is Jan 1, 2027. It is the rung the whole "will crypto get its rulebook this year" question settles on, it carries 406,849 contracts of open interest on more than a million traded, and its book is one cent wide at 21/22. No dusty corner of the exchange trades like that; this is a crowded, contested price. It is the most considered opinion on the board, and it still reads 22 cents with the White House pushing and a vote on the calendar, which tells you the endorsement everyone saw coming was already in the price.
Why 2027 Trades SO Much Higher Than 2026
Now the promised tell. While the November and December rungs and the back half of the curve all rose, the Before Oct 1, 2026 contract slipped from 9 cents to 8. Same news, opposite direction. A glitch would look random; this is coherent. Traders concluded the bill is more likely to pass eventually (the far rungs rose) and less likely to pass fast (the near rung fell), because the news that mattered was not the endorsement. It was the confirmation of the schedule. Once Thune's cloture filing fixed September 15 as the starting gun, the fantasy of a quick pre-October signing died. You cannot start the Senate's slowest process on September 15 and be at a signing ceremony two weeks later, and the 8-cent rung now says so.
Walk the calendar forward and the shape of the curve draws itself. The Senate reconvenes September 14. Cloture on the motion to proceed comes September 15. Even in the friendly scenario where seven-plus Democrats cross, the amendment fights over ethics and illicit-finance provisions are the actual negotiation, and they have not been resolved in a year of trying. Clear all of that and the House still has to swallow whatever the Senate changed. The market puts 4 points on November alone (16¢ to 20¢) and just 2 on December, which is a quiet insult to the lame-duck-magic theory: the window where post-election Congresses traditionally attach stalled bills to must-pass vehicles is priced as a longshot, not a plan.
Meanwhile the same White House meeting that lit up this ladder is part of a broader macro-policy picture traders are pricing all fall; the Fed's September decision lands the very same week as the cloture vote, and the 2026 midterms decide who controls the floor time this bill needs if it slips into 2027. Those are not side notes. The midterm rung is arguably load-bearing: a changed Senate in January 2027 reshuffles every assumption behind the 41-cent July rung.
A Worked Example: Reading A Cumulative Ladder
Each rung is cumulative, so the probability the bill becomes law inside a window is one rung minus the previous one. That subtraction is where this board gets interesting:
| Window | Math | Implied chance |
|---|---|---|
| September 2026 | 8¢ − 1¢ | ~7% |
| October 2026 | 16¢ − 8¢ | ~8% |
| Nov–Dec 2026 | 22¢ − 16¢ | ~6% |
| H1 2027 | 41¢ − 22¢ | ~19% |
| H2 2027 | 50¢ − 41¢ | ~9% |
| 2028 Or Never (By This Ladder) | 100¢ − 50¢ | ~50% |
The single fattest window on the entire board is the first half of 2027, at roughly 19 points. The market's modal story is not "September vote, October law." It is: the September vote goes well enough to keep the bill alive, the hard negotiating happens over the winter, and a reconciled text reaches the president's desk in the first half of 2027, most plausibly with the new Congress seated.
One craft note, because this is where prediction-market pages usually mislead people: these rungs are one cumulative curve, not independent contracts, so you never sum them or de-vig them to 100 the way you would a field of election candidates. The discipline is the same one sharp bettors apply everywhere, comparing the price you are offered against a fair number you computed yourself. That is literally what line shopping is; OddsShopper's live odds screen does that comparison across every major sportsbook for game lines, but it does not carry a Kalshi legislative contract like this one, so here the subtraction table above is the whole toolkit. (Bitcoin traders got the same lesson from Kalshi's $100K timing ladder, which is built the identical way, and the Ethereum board rhymes with it.)
What Moves This Ladder Next
Three catalysts, in order.
September 15 itself. A 60-plus cloture vote should lift the November and December rungs first, because it converts "alive" into "moving." A failed vote likely bleeds the 2026 rungs toward the September price while the 2027 rungs hold, since a rerun stays available and the market's base case already lives in 2027.
The amendment texts. The disputes are known: ethics provisions, AML language, DeFi treatment, stablecoin provisions. The first leaked compromise text on any of them moves this ladder more than any rally speech, in either direction.
The midterms. If the bill is not law by November, the composition of the next Senate becomes the dominant variable, which is exactly what the fat H1-2027 window is already saying.
If you want to trade any of this, Kalshi is a CFTC-regulated exchange, contracts are 18+ with availability varying by state, and a price is not a promise; a 50-cent rung is priced to lose as often as it wins. Our Kalshi promo code page covers current signup offers, and if you are weighing venues, the Polymarket review walks through the main alternative. This is not a market our betting tools cover, so I will not pretend there is a screen to hand you; the closest thing we publish is the daily graded read on the markets we do track, free at the expert picks hub, and the daily Kalshi hub grades our prediction-market reads in public every morning.
The Bottom Line
The Clarity Act ladder just gave a clinic in reading repricings. Loud news arrived, the market got more bullish on passage and less bullish on speed, and the one rung that fell is the one that best understood the Senate calendar. Watch the 8-cent October rung on September 16: if the cloture vote lands, that little contract, the same one that slid while the back of the ladder rose, becomes the purest read on whether Washington intends to finish this year or merely intends to keep trying. Either way, the board has already told you its story. It is not "no." It is "not yet," at 22 cents this year and a coin flip by 2028.

FAQ
What Are The Odds The Clarity Act Passes In 2026?
About 22 percent. As of August 20, 2026, Kalshi's "before January 1, 2027" contract traded at 22 cents on a 21/22 book, with 406,849 contracts of open interest. The same ladder prices passage before July 2027 at 41 cents and before 2028 at 50 cents.
What Happens In The Senate On September 15?
A cloture vote on the motion to proceed to the Clarity Act, set for 2:15 p.m. ET. It needs 60 votes. Winning it does not pass the bill or even start debate on the bill itself; it only clears the way for the Senate to take the bill up. Losing it does not kill the bill either.
What Is The Clarity Act?
The Digital Asset Market Clarity Act is the crypto market structure bill that would define which digital assets count as securities versus commodities and split oversight between the SEC and the CFTC. The House passed it in July 2025; the Senate has not yet voted on its version.
Why Does The Market Price 2027 SO Much Higher Than 2026?
Because the rungs are cumulative and the calendar is short. Even a perfect September 15 leaves floor debate, amendments, unresolved fights over ethics and illicit-finance provisions, and a House-Senate reconciliation, all before January 1. The single fattest window on the board is the first half of 2027, at roughly 19 points.
Is The Clarity Act Market On Kalshi Liquid?
Yes by prediction-market standards. The before-2027 rung alone has traded over a million contracts with 406,849 of open interest and a one-cent-wide book. The settled and near rungs have traded another three million-plus combined.
