SEC Commissioner Hester Peirce has submitted her formal resignation from the US Securities and Exchange Commission, effective Oct. 2.
Peirce, also known as “Crypto Mom” amid her advocacy of clear, rules-based regulation of the crypto industry, posted a copy of her resignation letter on her X account Friday.
In the letter, she thanked the president for the “honor of her professional lifetime” serving as a commissioner and said she was leaving the SEC under the excellent leadership of Chairman Paul Atkins and Commissioner Mark Uyeda, the two remaining members, who are both Republicans.
Peirce served on the commission for about eight years. Since Feb. 4, 2025, she was also director of the agencys Crypto Task Force. Her term at the SEC officially expired in June 2025, but commissioners “may continue to serve up to approximately 18 months after terms expire if they are not replaced before then,” according to the agency.
Peirce will join law school as associate professor
Cointelegraph reported in May that Peirce planned to join the law school of Regent University in Virginia as an associate professor in November. Peirce is expected to help the law school bolster its academic focus in several areas, including federal litigation, securities regulation and digital assets, according to the university.
Peirce‘s seat may not be filled immediately. Caroline Crenshaw, the agency’s previous Democratic commissioner, departed in January, 18 months after her term ended and no nominations to fill that seat have been made by President Donald Trump.
Since Trump took office in January 2025, the SEC has radically changed its approach to crypto regulation and enforcement. The agency dropped several enforcement actions and investigations into crypto companies, including those tied to Trump and his family.

Since its formation, the Crypto Task Force has been examining how existing securities laws should apply to digital assets and decentralized systems.
Cointelegraph reported in June that Peirce said publishing open-source code should not subject software developers to federal securities regulations, weighing in on a longstanding debate over developer liability in decentralized finance.
Peirce‘s remarks aligned with the SEC’s broader shift away from what Atkins has described as “regulation by enforcement.”
