Who is Harriet Hageman? The Republican Congresswoman Eyeing Cynthia Lummis’ Senate Seat

• Cynthia Lummis has announced that she won’t run for reelection in 2026.
• Lummis’s departure leaves a political opening in Wyoming and a policy vacuum for crypto advocates in the Senate.
• Harriet Hageman, the House Representative from Wyoming, is considering running for Lummis’s Senate seat.

With Cynthia Lummis announcing that she won’t seek reelection in 2026, the U.S. crypto sector is set to lose one of its most important champions in Washington.

Now, the future of American crypto policy may rest on who replaces her.

A strong contender for the role is Harriet Hageman, Wyoming’s House Representative, who is reportedly considering running for Lummis’s seat.

Cynthia Lummis to Retire From the Senate

Since arriving in the Senate in 2021, Lummis has been one of the most visible and outspoken advocates for digital assets in Congress.

A long-time Bitcoin holder, she positioned Wyoming as a testing ground for crypto-friendly policy well before Washington fully engaged with the sector.

During her tenure, Lummis has championed issues ranging from clearer regulatory definitions for digital assets to more favorable tax treatment for everyday crypto transactions.

She co-sponsored several high-profile crypto bills, including bipartisan efforts to clarify the roles of the SEC and CFTC, protect self-custody rights, and integrate stablecoins into the U.S. financial system.

The six months, however, have underscored ongoing challenges for U.S. crypto legislation.

Even as Republicans have rallied behind the cause, Democratic opposition and the longest government shutdown in U.S. history have derailed progress on highly anticipated market structure legislation.

Plans to establish a U.S. Bitcoin reserve—one of Lummis’s flagship policies—have also fallen flat, or been watered down to the point of irrelevance.

When Lummis announced on Dec. 19 that she would not run for a second Senate term, she acknowledged that her stamina “doesn’t match up” with what the job requires.

“In the difficult, exhausting session weeks this fall, I’ve come to accept that I do not have six more years in me,” she said in a statement.

Harriet Hageman Eyes Senate Bid

Lummis’s announcement leaves both a political opening in Wyoming and a policy vacuum for crypto advocates in the Senate.

Hageman, who Axios reported is eying a run in the 2026 race, could be a strong contender to fill the Senate seat.

The report cited Republican operatives and lawmakers who view Hageman as the most natural successor to Lummis, given her statewide profile and MAGA-aligned politics.

The story quickly gained traction in Washington, where an open Wyoming Senate seat is seen as safely Republican but strategically important.

For the crypto industry, the key question raised by the report was whether Hageman would simply vote with the party, or actively engage in shaping digital asset policy the way Lummis did.

Hageman’s Crypto Track Record

While Hageman has not made crypto a defining personal cause in the way Lummis did, her voting record places her firmly within the industry’s preferred legislative coalition.

In the House, she has consistently voted in favor of pro-crypto bills and resolutions, including the FIT21 Act, the GENIUS Act, the CLARITY Act, and H.J. Res. 25.

Hageman also co-sponsored the CBDC Anti-Surveillance State Act, which seeks to block the Federal Reserve from issuing a retail central bank digital currency.

If she formally launches a Senate bid and wins, Wyoming is likely to remain a reliable pro-crypto state in Congress, even if the style of advocacy shifts from Lummis’ full-throated evangelism to more muted alignment.
