The fight that has been blocking US crypto legislation since January is finally on paper. Senators Thom Tillis and Angela Alsobrooks released the compromise text on stablecoin yield late Thursday, the provision that pulled a Senate Banking Committee markup back in January and has held up the entire CLARITY Act since.
The deal looks like banks won the argument and crypto kept a foothold.
What the text actually does
Two lines matter. The first one bans any reward that is “economically or functionally equivalent” to interest on a bank deposit. That language is broad on purpose. It closes the obvious workaround where a crypto platform pays you yield on idle USDC and calls it something other than interest. Affiliates, structuring, technical wrappers, all blocked.
The second line keeps activity-based rewards alive. Cashback for a USDC transaction, points for using a stablecoin in DeFi, transaction-tied incentives. Those still work. The test is whether the reward depends on activity or on holding a balance. Hold-and-earn is dead. Use-and-earn survives.
Coinbase policy chief Faryar Shirzad said the final language was hammered out with the White House, Treasury, and Senate negotiators. He admitted banks gained more control than crypto wanted, but framed the activity-rewards carveout as a meaningful win. Wintermute’s Hammond had pegged the bill’s 2026 chances at just 30% when markets were pricing 61. Polymarket now sits around 46% odds.
May 21 is the cliff, not a soft deadline
Brad Garlinghouse said the quiet part out loud at XRP Las Vegas on April 30. If the CLARITY Act does not clear the Senate Banking Committee before the Memorial Day recess on May 21, the bill is shelved until 2030.
That is not just a Garlinghouse line. Senator Cynthia Lummis said the same thing at Bitcoin 2026 on April 27. So did Senator Bernie Moreno. The math is brutal: Senate breaks for August, then midterm campaigns swallow September and October. After November the House and Senate composition changes, and the rare alignment between House, Senate, and White House on crypto evaporates.
The Senate returns May 11. Tillis has asked Banking Committee Chair Tim Scott to schedule a markup that week. That gives the bill roughly eight working days to pass committee, get reconciled with the Senate Agriculture Committee version, then reconciled again with the House text from July 2025, then survive a 60-vote floor vote, then reach Trump’s desk.
Eight working days. Five sequential steps. That is the real story.
Who is pushing, who is dragging
Over 120 crypto firms have signed on as backers, including Coinbase, Kraken, Circle, and Andreessen Horowitz. The White House is publicly behind it. SEC Chair Paul Atkins and Treasury Secretary Bessent have both endorsed the framework. The House passed its version with 294 votes in July 2025, well above filibuster-proof territory.
What is dragging? Two things. The April markup got eaten by the Kevin Warsh Fed nomination, which consumed the Banking Committee calendar for weeks. And Senate Democrats have raised concerns beyond yield: DeFi protections, ethics rules around government officials with crypto exposure (read: Trump family), and pending CFTC and SEC vacancies they want filled before voting yes.
The Senate floor needs 60 votes. That requires Democratic crossover. The Tillis-Alsobrooks structure (Republican plus Democrat on the Banking Committee) is meant to signal exactly that, but it is one thing to write a compromise and another to actually whip the votes. Coinbase CEO Brian Armstrong reversed his January opposition and is now backing the bill, which removes one of the bigger crypto-side dissenters from the conversation.
What this means for stablecoin businesses
If the bill passes as written, the business model that pays customers to park USDC or USDT on a platform is over in the US. That hits Circle directly. It hits any exchange that has been quietly competing with savings accounts. Coinbase shares dropped almost 10% when the original compromise leaked in March, Circle dropped 20% the same day. The market read that as a loss.
But the activity-based carveout is not nothing. Stablecoin payment rails, DeFi integrations, merchant rewards programs, all of those keep working. For stablecoin holders weighing USDT versus USDC, the practical effect is mostly about where you can earn rewards, not whether the stablecoin itself is at risk. The yield mechanics get reshaped, the underlying asset does not.
Three scenarios for the next three weeks
Scenario one. Banking Committee markup happens the week of May 11, the bill clears committee, and the Senate finds floor time before May 21. This is the Galaxy Research base case at 50-50. It requires no surprises, no last-minute objection from Senate Democrats, and a clean reconciliation path.
Scenario two. Markup happens but the floor vote slips past May 21 into the summer recess. Galaxy Digital’s Mike Novogratz said this week the bill “probably gets done in May,” but probably is doing a lot of work in that sentence. A summer slip means the bill comes back in September, when midterm politics has poisoned the well.
Scenario three. Banks decide the activity-based carveout is too generous and reopen the fight. Or Senate Democrats pull back on DeFi or ethics. Either way the markup gets postponed again, and 2026 is dead. Lummis and Moreno both say the next window is 2030.
The watch list for the next 21 days
Two things to track. First, whether Senator Tim Scott actually schedules the Banking Committee markup for the week of May 11. If that notice does not post by May 7 or 8, the calendar is in trouble. Second, watch the bank lobby. JPMorgan’s Jamie Dimon already signaled openness to transaction-based rewards in interviews, but the American Bankers Association has been the harder-line voice. If they go quiet, the deal holds. If they make new noise, the markup slips.
Twenty-one days to either pass the most consequential US crypto legislation in years or watch it die for four. The text exists. The clock is running.
