On March 28, 2026, a new set of U.S. policy moves highlighted how quickly crypto regulation is evolving, from tax treatment for stablecoins to proposed limits on stablecoin yield products. The Digital Asset PARITY Act draft would exempt certain stablecoin transactions from capital gains tax and add wash-sale rules to crypto, while Coinbase is pressing for changes to CLARITY Act language ahead of expected text in late March or early April 2026. Separately, California Gov. Gavin Newsom issued an order barring state officials and close associates from using non-public information to bet on prediction markets.

A bipartisan group of U.S. senators introduced the Public Integrity in Financial Prediction Markets Act of 2026 on Thursday, aiming to bar government officials from trading prediction-market contracts using nonpublic information. The proposal would fine violators an amount equal to twice any profits, and it requires reporting within 30 days for any wager over $250 with detailed trade disclosures.

An ECB working paper analyzing Aave, MakerDAO (now Sky), Ampleforth, and Uniswap found DeFi governance power concentrated among a small set of holders and delegates, based on snapshots from November 2022 and May 2023. The study says the top 100 holders controlled more than 80% of governance tokens, while about one-third of top voters could not be identified, complicating accountability and regulatory oversight.

Rep. Maxine Waters sent a March 26 letter to Kansas City Fed President Jeff Schmid asking how Kraken Financial obtained approval for a limited purpose Federal Reserve account and what conditions were attached. The letter presses for details on permitted services (including FedACH, Check Services, FedCash, and Fedwire Securities Services), balance and liquidity limits, and any additional oversight beyond Wyoming’s SPDI framework, with a written response requested by April 10, 2026.

Draft legislative language circulated on Capitol Hill earlier this week as negotiators again tried to settle how stablecoin rewards should be treated. The issue has been stuck for about a year and, according to Coin Center policy director Jason Somensatto, remains the main obstacle to moving broader crypto legislation forward.

P2P.me said its team controlled an on-chain account labeled "P2P Team" that wagered on whether the project would hit a $6 million fundraising target. The project said the trades were made about 10 days before the raise ended using its foundation treasury, and it plans to unwind the positions and return proceeds. The disclosure followed Polymarket's March 23 update that tightened definitions around insider trading and manipulation.

California Gov. Gavin Newsom signed an executive order Friday that immediately prohibits gubernatorial appointees from using confidential, non-public information to profit on prediction markets including Polymarket and Kalshi. The directive also bars appointees from helping spouses, family members, business partners, or associates place bets using insider details obtained through official duties.

Intercontinental Exchange (ICE), owner of the NYSE, has made a $600 million cash investment in Polymarket, completing a structured program it first announced in October 2025. The company also said it expects to buy up to $40 million of Polymarket securities from existing holders, bringing the combined primary and secondary components toward the original plan's upper limit.
