The Senate voted 49-50 on September 15, 2026, against advancing the CLARITY Act, leaving the crypto market-structure bill short of the 60 votes needed to proceed as stablecoin-reward rules continued to divide banks and crypto companies. Fairshake, backed by Coinbase, a16z and Ripple, plans to spend $30 million on negative advertising against Ohio Senator Sherrod Brown ahead of the November midterm elections, citing concerns that a Brown return could lead to a chairmanship of the Senate Finance or Banking Committee. Stand With Crypto says its more than 4 million members will consider lawmakers’ CLARITY Act positions. Prediction markets put Brown’s Ohio winning probability at 64%, up 10 points after the campaign announcement, while temporary SEC and CFTC guidance has reduced some immediate pressure for legislation without replacing a permanent oversight framework.
