Polymarket traders pushed CLARITY Act passage odds from 46% to 73% in just two weeks — even as the White House’s top crypto adviser publicly accused America’s largest bank lobbyists of refusing to show up for the February meetings that were supposed to settle the bill’s stablecoin yield rules. With a Senate Banking Committee markup scheduled for May 14 and the White House targeting a July 4 signature, the prediction-market scoreboard is now swinging on every leaked letter, X post, and trade-association blast.

KEY FACTS AT A GLANCE
- The accusation: White House crypto adviser Patrick Witt said on X that ABA CEO Rob Nichols and other bank trade CEOs “refused” to attend February stablecoin meetings.
- The trigger: Nichols sent an emergency Sunday letter to every US bank CEO demanding “immediate engagement” against the bill’s stablecoin yield language.
- Polymarket reaction: Odds of 2026 passage swung from 46% to a 90% intraday peak before settling at 73% — then slipped to 62% after the bank lobby formally rejected the compromise.
- The deadline: Senate Banking Committee markup on May 14, 2026 at 10:30 AM ET. White House signature target: July 4, 2026.
- The dispute: Tillis–Alsobrooks compromise bans passive yield on stablecoin reserves but allows activity-based rewards tied to payments, transfers, or platform participation.
What Patrick Witt actually said
The fight broke into the open on Sunday, May 11. Rob Nichols, president and CEO of the American Bankers Association, sent an emergency letter to every member-bank CEO in the country, calling for “immediate engagement” against what he framed as a stablecoin yield loophole in the Senate’s CLARITY Act draft. Days before a Senate Banking Committee markup, the message landed like a fire alarm.
Patrick Witt, executive director of the White House Presidential Advisory Committee on Digital Assets, responded on X within hours — and named Nichols directly.
“I specifically requested the attendance of Mr. Nichols and other bank trade CEOs at the meetings we hosted back in February to resolve the stablecoin rewards/yield issue. They refused. I guess the White House was beneath them? In their defense, I wouldn’t want to have to defend their position in public either.”
— Patrick Witt, White House Presidential Advisory Committee on Digital Assets, X post, May 11, 2026
Witt’s framing reset the timing of the dispute. The banking industry was treating the May 14 markup as the moment to fight; Witt’s response argued the time to negotiate had been four months earlier — and that bank CEOs personally chose not to show up.
How prediction markets reacted
The Polymarket question “Will the CLARITY Act be signed into law in 2026?” started May trading at just 46%. By mid-week the implied probability had spiked to roughly 80%, and over the following weekend traders briefly pushed the contract to 90% intraday as rumors of a deal circulated. By Monday, May 11 — the same day as the Witt-Nichols exchange — the price had settled back to 73%. By the next morning, after the banking lobby formally rejected the compromise text, it slid again to 62%.
Kalshi’s parallel contract was tracking the same arc — 69% as of May 11, just under Polymarket’s reading. Last month, Kalshi surpassed Polymarket as the #1 prediction market by global volume, so the convergence between the two books is no longer just a curiosity — it is the closest thing crypto policy has to a real-time consensus indicator.
The February meetings the banks “refused”
Witt’s accusation hinges on a series of White House mediation sessions held in February 2026 to settle whether stablecoin issuers and crypto exchanges should be allowed to share yield with users. According to White House sourcing in multiple outlets, Witt invited the CEOs of the three largest banking trade groups — the American Bankers Association, the Bank Policy Institute, and the Independent Community Bankers of America — and was met with a no on the CEOs themselves. Trade-association staff did attend; the principals did not.
On Sunday, May 11, Nichols sent the letter that finally pulled the dispute back to the surface. The text — quoted in coverage from the ABA Banking Journal and elsewhere — used the phrase “deposit flight” three days before a Senate vote.
“Without additional changes, we believe the current proposal would unnecessarily incentivize the flight of bank deposits into payment stablecoins, putting both economic growth and financial stability at risk.”

The Tillis–Alsobrooks compromise
The text that the banking lobby is trying to rewrite was negotiated by Senators Thom Tillis (R-NC) and Angela Alsobrooks (D-MD) earlier this year. Its central move is a distinction the crypto industry has been pushing for since the original GENIUS Act fight: passive yield versus activity-based rewards.
Under the compromise, a stablecoin issuer cannot pay an account holder yield simply for holding a stablecoin balance — the “idle yield” that crypto-industry lawyers have publicly conceded was always politically dead. But platforms can still offer rewards tied to actual usage: payments, transfers, or participation in liquidity, staking, or loyalty programs. The banking groups’ position is that the second category is just the first one in disguise — a product that competes with deposit accounts without the regulatory burden of being one.
The numbers fight: $2.1B vs 20%
The White House and the banking industry are not just disagreeing about policy — they are publishing wildly different numbers about what the same policy would do. The two sides cannot both be right.
The White House Council of Economic Advisers, in an April 2026 paper, modeled the effect of prohibiting stablecoin yield on bank lending and found a baseline impact of roughly $2.1 billion — about 0.02% of total US bank lending. Even an “implausible” worst case, the paper said, would only push the figure to $531 billion, or 4.4%.
“A yield prohibition would do very little to protect bank lending, while forgoing the consumer benefits of competitive returns on stablecoin holdings.”
— White House Council of Economic Advisers, April 2026 research paper
The May 8 joint letter from six banking associations — the ABA, Bank Policy Institute, Consumer Bankers Association, Financial Services Forum, Independent Community Bankers of America, and National Bankers Association — argued the opposite. Their estimate: deposit flight driven by yield-bearing stablecoins could cut consumer, small-business, and agricultural lending “by one-fifth or more.” Treasury Department figures cited by the same coalition put potential deposit outflows as high as $6.6 trillion.
Why the stablecoin market matters
The total stablecoin market sits near $323 billion as of May 2026 — small next to the roughly $18 trillion in US commercial bank deposits, but moving fast. Tether’s USDT held about 58% market share with a $185 billion market cap; Circle’s USDC reserves clocked in around $67 billion. In 2025, USDC processed $18.3 trillion in transactions and USDT $13.3 trillion, putting combined stablecoin transaction volume above $33 trillion for the year.
Those volumes are why both sides are fighting about a market that is still less than 2% the size of US deposits. The banking industry is not arguing about today; it is arguing about a yield-on-stablecoin product that, in their model, would scale with the underlying market and eventually compete head-on with checking and savings accounts that currently pay 0.4%.
Coinbase and the “banking cartel” pushback
Witt was not the only one who lit up X on Monday. Senator Bernie Moreno (R-OH), a Banking Committee member, accused the lobby outright.
“The banking cartel is in full panic mode.”

Coinbase Chief Legal Officer Paul Grewal — whose company runs a federally-regulated prediction market of its own alongside its exchange business — responded directly to Nichols’ letter by claiming the ABA was now litigating a fight it had already lost.
“Maybe the CEO didn’t get the message from the people actually in the room at the WH in meeting after meeting. You got ‘idle yield’ killed. I know because I was there — you weren’t. Take yes for an answer. Move on. Stop wasting the time of the Senate and American people.”
— Paul Grewal, Chief Legal Officer, Coinbase, X post, May 11, 2026
Cody Carbone, CEO of the Digital Chamber, was blunter: “The arrogance is astounding.” The crypto industry has been arguing for months that the banking lobby’s preferred outcome — strip activity-based rewards entirely — would gut the GENIUS Act framework already on the books and re-open issues that crypto firms believed were settled.
The road to May 14 and July 4
Senate Banking Committee Chairman Tim Scott (R-SC) has formally scheduled the markup for May 14, 2026 at 10:30 AM ET in the Dirksen Senate Office Building. Even if it clears committee that day, the bill needs 60 floor votes for cloture, four Senate working weeks in June for floor passage, and then a House vote — all before the White House’s symbolic July 4 deadline.
What to watch
The most readable signal between now and Independence Day is not the cable-news talking heads — it is the prediction-market chart. Polymarket’s CLARITY Act contract has already moved on every meaningful event in this fight: the Tillis–Alsobrooks compromise, the CEA paper, the joint banking letter, the Witt-Nichols exchange. As mainstream finance increasingly looks to prediction markets as a real-time signal, the next four to eight weeks should give a clean test of whether market traders or trade-association lobbyists are pricing the politics correctly.
If the Banking Committee passes the bill on May 14 with the activity-based rewards language intact, expect Polymarket back into the high 70s. If the committee strips the rewards language under bank pressure, the contract will likely collapse below 50%, and the July 4 deadline becomes a public-relations target rather than a real one.
KEY TAKEAWAYS
- Witt’s accusation is the news peg — the White House publicly named Nichols and the bank trade CEOs for skipping February stablecoin meetings, just three days before the Senate markup.
- Polymarket has become the live scoreboard — odds swung 46% → 90% → 73% → 62% in two weeks, with each move tracking a specific political event.
- The compromise is narrower than the lobby is portraying — passive yield is already banned; the fight is about activity-based rewards tied to actual platform usage.
- The economic numbers don’t agree — the White House CEA models a $2.1 billion lending impact (0.02%); banking groups warn of cuts “by one-fifth or more.”
- May 14 and July 4 are the dates that matter — committee markup, then a four-week Senate runway, then a House vote, before any signature.
