As the question of stablecoin regulation heats up in the US Senate, so has the issue of which members are personally invested in cryptocurrencies and cryptocurrency firms.

On May 19, the Senate voted to invoke cloture and move ahead with the GENIUS Act, which would provide a regulatory framework for stablecoins. The measure passed 66-32, with 16 Democrats supporting the bill.

Democratic concerns over corruption and politicians’ ties to cryptocurrency firms made the bipartisan move controversial. After the vote was finished, Colorado Senator Michael Bennet introduced the STABLE GENIUS Act. The bill would prevent members of Congress from issuing or investing in digital currency and require them to put their crypto in a blind trust while in office.

Bills to prevent members of Congress from investing in companies they regulate have had little success. However, lawmakers are still required to disclose rough estimations of their, their spouse’s and their children’s investments. Here are 11 US senators who have invested in crypto firms.

Montana

Tim Sheehy, Republican

Tim Sheehy is a newcomer to the Senate, first securing his election in the 2024 cycle. In his campaign, Sheehy contrasted himself against his opponent, former Senator Jon Tester, stating, “Crypto represents the future of finance and the internet, and thousands of jobs for America.”

Investments: According to a June 2024 filing, Sheehy has an investment between $1,001 and $15,000 in Intercontinental Exchange, which offers futures contracts on cryptocurrencies.

Steve Daines, Republican

Ohio

Rhode Island

Sheldon Whitehouse, Democrat

Sheldon Whitehouse is the senior senator of his state, serving in Congress since 2011. In the last several years, he has raised concerns over the energy consumption of Bitcoin mining, as well as the potential for Russia to use crypto to evade US sanctions. He has voted against the GENIUS Act and co-sponsored the Digital Asset Anti-Money Laundering Act of 2023, which Stand With Crypto rated as “very anti-crypto.” 

Investments: According to an August 2024 filing, Whitehouse has investments in Tesla, Block and PayPal. All investments are between $1,001 and $15,000. 

This list is not exhaustive; there are plenty of companies in which lawmakers invest that are affected by cryptocurrency price movements and market effects. It also does not include any members of the House of Representatives, where crypto regulation is similarly in the works. 

Lawmakers will likely become more interested in investing in crypto as it becomes more mainstream and potential obstacles to congressional investments flounder and fail to move forward.
