Why it matters
The SEC falls to two commissioners while the industry's main Washington trade group changes CEO days after its market-structure bill failed in the Senate, and the departing figures led work on stablecoin law and the SEC's crypto task force. Peirce's resignation is effective Oct. 2, with a replacement still unnamed.

What happened
The Blockchain Association said on Friday that CEO Summer Mersinger will step down on Oct. 16 and that founding CEO Kristin Smith will return as interim CEO. CoinDesk and Cointelegraph put Smith's start on Oct. 16, while Unchained and NewsBTC say Oct. 17. Unchained and NewsBTC report Mersinger will stay on as an adviser through the end of 2026; Cointelegraph instead says she leaves the organisation at year's end. Both moves follow the Senate failing to advance the Digital Asset Market Clarity Act, and neither the trade group's announcement nor Peirce's resignation mentioned the bill. The association credits Mersinger, a former CFTC commissioner who joined in June 2025, with its work on the GENIUS Act and the joint SEC-CFTC interpretation that most crypto assets are not themselves securities. The same day, Hester Peirce posted her resignation to President Trump, setting her last day as Oct. 2 and leaving the SEC with Chairman Paul Atkins and Mark Uyeda; no successor has been named.
