Clarity Act's odds slide back toward a coin flip as the calendar, not the crypto lobby, takes over

After a springtime surge on a stablecoin-yield truce and Coinbase's blessing, the US crypto industry's marquee market-structure bill is running out of Senate days — and the prediction markets have noticed.

The Clarity Act — the bill the crypto industry considers its single most important piece of legislation because it would finally sort which digital assets the SEC regulates as securities and which the CFTC regulates as commodities — has swung from euphoria to doubt in about seven weeks. The swing has less to do with the bill's contents, which have barely moved, than with the shrinking number of days Congress has left to pass anything before it decamps for the August recess and, after that, the midterm campaign.

The May high. In early May, per DL News, Punchbowl News reported that senators had struck a deal on the question that had stalled the bill for months: whether, and how, stablecoin holders can be paid yield. The reaction that mattered came from Coinbase CEO Brian Armstrong, who posted "Mark it up" — read as an endorsement of a committee markup. That matters because Armstrong single-handedly froze the bill in January, pulling his support on the eve of a scheduled markup over its stablecoin treatment, prompting Senate Banking Chair Tim Scott (R-SC) to postpone the vote. On the news of the deal plus Armstrong's turnaround, Polymarket's odds of 2026 passage jumped from 46% to 64%, by DL News's account. Scott said the committee was "nearing consensus" and working toward a bipartisan markup in May.

The mechanics of the yield deal. Last year's GENIUS Act banned stablecoin issuers from paying interest on their tokens — a concession to banks worried depositors would flee checking accounts for higher-paying digital dollars. What GENIUS left ambiguous was whether third parties — exchanges like Coinbase — could pay yield instead. Banks lobbied to close that gap. The Clarity compromise, according to draft text DL News reviewed, bans yield "that is economically or functionally equivalent to the payment of interest or yield on an interest-bearing bank deposit," while permitting "rewards or incentives" on "bona fide" activities — transactions, payments, transfers, remittances, DeFi liquidity provision. Where that line falls is left to regulators, who would get one year to write the rules. Investor Nic Carter's read: "The banks won." Van Buren Capital general counsel Scott Johnsson's: "This is fine… It may not feel like it, but it is."

The June comedown. By late June the direction had reversed. The bill did clear the Senate Banking Committee in a bipartisan 15-9 vote (CoinDesk). But on June 29, Decrypt reported Galaxy had cut its 2026-passage estimate to 50%. A day later, CoinDesk reported Polymarket at 48% — down from a mid-May peak of 70% — with investment bank Jefferies (analysts led by Andrew Moss, in a Tuesday note) warning of "elevated volatility" as concerns over ethics provisions, illicit-finance rules and limited Senate floor time weigh on the odds. Lawmakers have "roughly 20 legislative days" before the August recess to merge competing Senate versions, clear procedural votes, reconcile with the House bill (passed nearly a year ago) and get it to President Trump. "Failure to pass Clarity before the August recess could push the bill out to next year, or even later, if Democrats flip the Senate in November," Jefferies wrote. JPMorgan made a similar time's-running-out point earlier in June.

Where the numbers diverge. The passage-odds figures don't line up cleanly across sources, and the reason is timing: DL News captured an early-May spike to 64% on Polymarket; CoinDesk cites a mid-May Polymarket peak of 70%; Galaxy put its own estimate at 50% on June 29; and Polymarket sat at 48% on June 30. Read in sequence, they tell one story — a spring rally that has since given most of its gains back — rather than a contradiction.

Key facts

• Committee vote: Senate Banking Committee passed the Clarity Act 15-9, bipartisan (CoinDesk, June 30).
• Passage odds, over time: Polymarket 46%→64% on the May yield deal (DL News); mid-May peak ~70% (CoinDesk); Galaxy estimate 50% (Decrypt, June 29); Polymarket 48% (CoinDesk, June 30).
• The yield rule: bans yield "economically or functionally equivalent to… an interest-bearing bank deposit"; allows "rewards or incentives" on "bona fide" activities; regulators get one year to write rules (DL News, from draft text).
• The clock: ~20 legislative days before the August recess to merge Senate versions, clear procedure, reconcile with the House bill and send to Trump (Jefferies, via CoinDesk).
• Coinbase: Armstrong froze the bill in January by pulling support; posted "Mark it up" in May (DL News).
• Price context: BTC ~$59,940–$60,019 across the two June sources (Decrypt June 29; CoinDesk June 30).

The real-world read

• The industry's own celebration was ahead of the odds. When Blockchain Association CEO Summer Mersinger said the deal "clears the path to a Senate Banking Committee markup and brings us meaningfully closer" to law, that was a lobbying group's press statement, not a neutral forecast — and it's worth discounting as such. The markup did happen; the bill then stalled anyway on floor time and new fights (ethics, illicit finance). The 70%→48% slide is the market pricing in what the celebration glossed over.
• Armstrong's reversal cuts both ways. He is credited in the same source with both killing the bill in January and reviving it in May. That is a lot of leverage for one CEO of one interested company, and worth naming plainly: Coinbase is not a disinterested observer — the yield "loophole" the bill would close is one Coinbase itself uses to pay rewards on USDC (CoinDesk). "Mark it up" is the tell that the industry got a version it could live with, not that the public did.
• "The banks won" vs. "This is fine." DL News quotes both. The honest read is that the yield compromise is vague by design — it kicks the hard definitional question to regulators for a year, which means the "win" for either side is provisional and reversible by whoever writes the rules.
• Mind who's talking, and why. Jefferies and Galaxy are the two loudest voices in the June sources, and both have skin in the game. Jefferies frames the whole thing as a volatility trade in named tickers — Circle (CRCL), Coinbase (COIN), CoinDesk-owner Bullish (BLSH) — which is a sell-side note's job, not a neutral policy read; note too that CoinDesk disclosing its own parent as an affected stock is the right move. Galaxy is a crypto firm forecasting crypto legislation. Their numbers are useful; their framing is interested.
• The Circle "loophole" story is doing quiet work. Jefferies calls the bill's implications for Circle "mixed" — closing the third-party-rewards loophole could slow USDC growth, but a delay buys Circle time to diversify. Left mostly unsaid in the celebratory May coverage: the same deal the industry cheered would directly crimp how USDC is distributed.
• What's conspicuously absent: none of the sources names a Democratic vote count on the floor, and Jefferies itself flags a possible Senate flip in November as the thing that could bury the bill "even later." The 15-9 committee vote was bipartisan; whether that survives to a floor majority is the unanswered question everyone is dancing around.

Opinion, and whose

• Jefferies (Andrew Moss et al.): passage would "unlock the next phase of institutional adoption" — tokenized securities, broader ETFs beyond BTC/ETH, revived crypto-infrastructure IPOs; delay would prolong reversible, agency-only regulatory guidance. Also expects "elevated volatility" in crypto equities and select tokens. This is a sell-side forecast.
• Galaxy: 2026 passage now a coin flip at 50% (Decrypt) — a crypto firm's estimate.
• Nic Carter: "The banks won." Scott Johnsson (Van Buren Capital): "This is fine." Both are market participants.
• Blockchain Association (Mersinger): the deal is "a step in the right direction"; committee should "move forward without delay." This is an industry lobby's advocacy.
• Tim Scott (Banking Chair): the committee is "nearing consensus" on a bipartisan markup — the chairman's characterization of his own bill.
