U.S. Senator Cynthia Lummis has announced she will not seek re-election, with her term ending in January 2027. As the chair of the Senate Banking Committee's digital assets subcommittee, Lummis has been a key figure in shaping cryptocurrency regulation. She has collaborated with Senator Kirsten Gillibrand to develop a regulatory framework for digital assets, clarifying the roles of the U.S. SEC and CFTC. This legislation is currently under review by the Senate Banking and Agriculture Committees and will require full Senate approval and coordination with the House version.
