Fairshake committed $30 million against Sherrod Brown in Ohio.
The crypto PAC, a group that pools money to influence elections, moved just days after the Senate failed to pass sweeping digital asset legislation.
The bill was the Clarity Act, which would have set a regulatory framework for the digital asset industry at the federal level.
The Senate failed to pass it last week in a procedural vote, the first test of whether a bill even gets a full debate.
Senate Democrats said they could not vote for a bill that would allow President Donald Trump to profit personally from the crypto industry, given his millions of dollars in income from multiple digital asset forays.
A Fairshake spokesperson confirmed the $30 million figure.
The group expects to announce more midterm spend decisions in the coming days and weeks.
The New York Times called this its most aggressive move yet ahead of the November midterms.
In 2024 Fairshake spent $12 million in Ohio to back Bernie Moreno, who defeated Brown.
Brown previously chaired the Senate Banking Committee, the panel that plays a major role in advancing crypto legislation.
As chair Brown called for a crackdown on the use of cryptocurrency to fund terrorism and evade sanctions.
Starting in April crypto money began flowing to Republican Senator Jon Husted, a vocal supporter of crypto innovation who faces Brown in November.
Stand With Crypto rates Husted as strongly supports crypto, and he backed the GENIUS Act.
Fairshake also backed Ruben Gallego and Elissa Slotkin, who voted against the Clarity Act last week.
Who should write the next digital asset rules, Brown or Husted? 👇
