Law Enforcement Letter Sinks CLARITY Act Passage Odds to 41%

The probability that the CLARITY Act becomes law dropped 14 percentage points to 41% on Polymarket within hours of a letter sent to the White House. Four major U.S. law enforcement groups signed the June 23 letter, addressed to Acting Attorney General Todd Blanche and crypto advisor Patrick Witt. The signatories included the National District Attorneys Association, the National Association of Assistant U.S. Attorneys, the International Association of Chiefs of Police, and the National Sheriffs’ Association – together representing more than 70,000 law enforcement professionals.

The groups said they support a regulatory framework for digital assets. They argued that Section 604 of the CLARITY Act, along with other provisions, could weaken tools for investigating financial crime. The letter specifically cited the Blockchain Regulatory Certainty Act (BRCA), which provides developer protections, as a concern.

“Since concerns regarding Section 604 first emerged earlier this year, our organizations have engaged constructively with lawmakers, Administration officials, and stakeholders regarding its potential impact on public safety and criminal enforcement,” the letter states.

The organizations wrote that digital assets are used in fraud, ransomware attacks, sanctions violations, drug trafficking, child exploitation, and money laundering. They warned that blanket exemptions could create “gaps in oversight and accountability” that criminal actors might exploit.

“Our concern is not with individuals who merely write or publish software code, nor with responsible technological innovation,” the groups said. “Rather, our concern is with broad exemptions that may shield individuals or entities whose activities facilitate the movement of digital assets.”

The letter also raised alarms about provisions that could reduce transparency and weaken anti-money laundering and counter-terrorism financing systems. It highlighted sections that might exclude mixers, tumblers, and some DeFi participants from registration and KYC requirements.

“No class of market participant should receive a blanket exemption from registration, know-your-customer (KYC), Bank Secrecy Act (BSA), or AML/CFT requirements,” the groups wrote.

The Law Enforcement Letter

The odds drop followed a period of growing opposition. Earlier this month, faith-based groups raised objections to the CLARITY Act’s DeFi provisions. The bill also faces scrutiny over an ethics rule affecting the White House crypto advisor. A related Senate crypto tax bill framework is moving through parallel proceedings.

The law enforcement letter landed just weeks before a critical hearing. The House has scheduled a July 17 hearing to advance the CLARITY Act. The bill’s sponsors have not publicly responded to the law enforcement concerns. The opposition from prosecutors and police chiefs adds institutional weight to the earlier criticism from religious and advocacy groups.

July 17 Hearing and Beyond

The hearing will test whether the bill’s backers can address the transparency and AML concerns without gutting the developer protections that crypto advocates want. The Polymarket odds, while down sharply, still price in a roughly two-in-five chance of passage. That suggests traders see room for compromise.

What would reduce the risk? If lawmakers amend Section 604 to explicitly carve out enforcement tools, the odds could climb back toward 55%. A softening of the law enforcement position – through negotiation or an updated letter – would also help. Conversely, additional opposition from the Treasury Department or financial regulators would push odds lower. A failure to hold the July 17 hearing could signal that the bill lacks the votes to clear committee.

The CLARITY Act’s trajectory affects the entire U.S. crypto market. A weakened bill would leave crypto firms without the regulatory safe harbors they have been lobbying for. Passage, even with amendments, would clarify tax treatment and custody rules for institutional investors. For now, the law enforcement letter has reset expectations. The July 17 hearing is the next concrete event that will show whether the bill can absorb the pushback.
