Wyoming Senator Cynthia Lummis said at the DC Blockchain Summit on Wednesday that the U.S. digital asset market structure bill is close to clearing Congress, with stablecoin yield and rewards remaining the primary obstacle. She indicated that disagreements between banking and crypto industry representatives over these returns are being worked through with the White House, and added that lawmakers believe concerns around DeFi have largely been resolved.

In a Tuesday notice, the US Securities and Exchange Commission outlined how it will interpret non-security crypto assets under federal securities laws and detailed a new token taxonomy for various types of digital assets. The agency said most crypto assets are not themselves securities, while tokenized traditional securities remain subject to securities rules. The announcement came as the SEC also reported the resignation of enforcement director Margaret Ryan, prompting public criticism from former official John Reed Stark.

Arizona Attorney General Kris Mayes announced on Tuesday that her office filed gambling and related criminal charges against the companies behind prediction market platform Kalshi, alleging it ran an unlicensed betting operation in the state and offered election wagering. Kalshi disputes the case, arguing it operates a federally regulated financial exchange under the exclusive jurisdiction of the CFTC and should not be treated like a state-regulated sportsbook or casino.

On Tuesday, the U.S. Commodity Futures Trading Commission's Market Participants Division issued a no-action letter to crypto wallet provider Phantom Technologies, allowing it to operate in certain ways without registering as a broker. Phantom says this position lets its non-custodial interface connect users to a registered exchange without assuming introducing broker obligations. The decision is among the first no-action responses for a crypto firm under CFTC Chair Michael Selig, who continues to assert the agency's authority over prediction markets while coordinating with the SEC.

A federal court in the Middle District of Alabama has granted a motion by former Binance CEO Changpeng Zhao to dismiss significant portions of a February 2024 complaint alleging Binance, Binance.US and Zhao violated the Anti-Terrorism Act by facilitating transfers to Hamas. The judge ordered the plaintiffs to file a second amended complaint by April 10 or face the risk of total or partial dismissal, while Binance later characterized the ruling as a “full and complete legal victory.”

A federal judge in the Southern District of Ohio has denied Kalshi's motion for a preliminary injunction seeking to stop state authorities from regulating its sports event contracts. The court found that Kalshi failed to show these contracts fall under the Commodity Futures Trading Commission's exclusive jurisdiction or that federal commodities law preempts Ohio's sports gambling statutes. Kalshi plans to appeal the ruling, which diverges from a recent federal court decision in Tennessee.

Wyoming Senator Cynthia Lummis is renewing efforts to establish a $300 de minimis tax exemption for small crypto payments as the Senate reviews a digital asset market structure bill that passed the House as the CLARITY Act in July 2025. She has proposed separate legislation capping eligible crypto transactions at $300 each and $5,000 annually, even as she plans to leave the Senate in January 2027.

On a Friday in response to a February inquiry from 11 US senators, Binance sent a letter denying that it directly processed transactions for Iran-based entities or dismissed staff for raising compliance concerns. The exchange argued that the Senate probe relied on media reports it called demonstrably false and said its internal investigation led to the removal of accounts allegedly linked to Iranian entities.

The US Securities and Exchange Commission has submitted an interpretative proposal to the White House outlining how federal securities laws should apply to specific crypto assets and transactions. The guidance, framed as a "token taxonomy," could carry more authority than staff statements and is currently under review alongside a separate CFTC submission on prediction markets. The move comes as Congress considers a crypto market structure bill and both market regulators continue to operate with fewer than their full complement of commissioners.
