PANews reported on November 12 that according to CoinDesk, US Democrat Ruben Gallego defeated Republican Kari Lake in the Arizona Senate election and won a seat. Although the Democrats lost control of the Senate in the 2024 election, Gallego's victory partially alleviated the loss. It is reported that Gallego voted in favor of the 21st Century Financial Innovation and Technology Act and a resolution to overturn the Securities and Exchange Commission's Staff Accounting Notice No. 121. Fairshake provided him with $10 million in support.

There are still 16 races in the House of Representatives that have yet to be determined. The Republicans have won 214 seats and only need to win four more to gain a majority in the next congressional term. The Democrats have currently won 205 seats, but the Republicans are still expected to win control of the House of Representatives. With Republican victories in the Senate and presidential elections, the Republicans are expected to control a unified government.

Fairshake has endorsed 56 candidates in House and Senate races, mostly in primaries in safe districts, meaning in those districts the primary winner is likely to also win in the general election.
