Sen. Cynthia Lummis, a key architect of efforts to pass sweeping crypto legislation and to codify a strategic bitcoin reserve, said she will not seek reelection. The Wyoming Republican’s term ends in January 2027. In a post on X on Friday, she said the past fall had taken a toll, describing herself as “a sprinter in a marathon.”

Lummis chairs the Senate Banking Committee’s digital assets subcommittee and has spent several years at the center of congressional efforts to regulate the crypto industry. She has worked closely with Sen. Kirsten Gillibrand on comprehensive legislation aimed at establishing a clear regulatory framework for digital assets, including defining oversight roles between the SEC and the CFTC.

The Senate Banking Committee has been moving toward advancing the bill after multiple meetings involving Democrats, Republicans, the crypto industry, and traditional finance stakeholders, with early next year targeted for amendments and a committee vote. The legislation would still need to be merged with work from the Senate Agriculture Committee, pass a full Senate vote, and then be reconciled with a House version approved over the summer.

Beyond market structure, Lummis has pushed for crypto tax reforms such as ending double taxation for miners and stakers and proposing a $300 tax-free transaction threshold. She has also advocated for legislation to cement President Donald Trump’s strategic bitcoin reserve into law. Despite her decision not to run again, Lummis said she is focused on delivering key bills to the president’s desk in 2026.
