U.S. Senator Cynthia Lummis of Wyoming, one of the strongest supporters of Bitcoin in Congress, has announced she will not run for reelection in 2026. This means she will leave the Senate when her term ends in January 2027.

Her decision is important because she has been a leading voice for Bitcoin policy in Washington.

Lummis, who is 71 years old, said she made the decision after realizing how demanding the job has become. Long legislative sessions have taken a physical and mental toll on her. She said:

She was first elected to the Senate in 2020 and took office in January 2021. From the beginning, Lummis stood out as one of Congress’s most vocal supporters of Bitcoin. She strongly supported President Donald Trump’s pro-Bitcoin agenda and often described digital assets as important to America’s future.

Trump himself praised her earlier this year, saying she was working closely with him to make America the “crypto capital of the world.”

During her time in the Senate, Lummis became known as the most knowledgeable lawmaker on Bitcoin and digital assets issues. She was named chair of the Senate Banking Subcommittee on Digital Assets, the first Senate group focused entirely on digital assets.

In that role, she pushed lawmakers to better understand Bitcoin and to create clear rules for the industry. Lummis worked on many digital-asset-related bills.

These included proposals to clarify how digital assets should be regulated and which government agencies should oversee them. She also supported changes to related tax rules and broader efforts to modernize financial laws so they would work with blockchain technology.

One of her boldest ideas was the Bitcoin Act. The proposal suggested that the U.S. government buy up to 1 million BTC over five years and hold it as a national reserve.

While controversial, the idea showed how strongly Lummis believed bitcoin could play a strategic role in the U.S. economy. She also played a key role in passing the GENIUS Act, a law that created federal rules for stablecoins.

The bill gave clearer guidance to companies like Circle and Tether, and marked one of the first major digital asset laws passed at the federal level.

Another major focus of Lummis’s work has been the digital asset market structure bill. The bill aims to clearly define how digital assets should be regulated and which tokens are securities or commodities.

It passed the House of Representatives in July but has stalled in the Senate. Although it was reviewed by key committees, it was not brought to a full vote before the holiday break.

Even though she plans to retire, Lummis said she will stay active until her term ends. “I look forward to continuing this partnership and throwing all my energy into bringing important legislation to his desk in 2026,” she said, referring to President Trump.
