Either way, more than a dozen new pro-crypto congressmen and women could head to Washington next year if they win and that could help reframe an ongoing debate over whether (and how) Congress intervenes must come to regulate the industry.

These deep-pocketed groups have sent money to candidates from both parties, from Alaska to New York State, and appear likely to help usher in what is already being called the most crypto-friendly Congress ever in 2025.

And its influence could continue beyond Election Day, with Politico reporting this week that at least one cryptocurrency super PAC has $78 million in the bank as of Tuesday — apparently to keep lawmakers focused on their pet issues.

One Senate race in particular is likely to be closely watched by bank CEOs like Jamie Dimon of JPMorgan Chase (JPM).

That is the battle in Ohio between Democratic Senator Sherrod Brown and his challenger Bernie Moreno. It’s a contest that could determine both control of the Senate in 2025 and who heads the crucial Senate Banking, Housing and Urban Affairs Committee.

That committee, which Brown currently heads, oversees the big banks and has been the scene of highly anticipated hearings in recent years, with CEOs forced to answer questions from lawmakers on a range of topics.

Whoever takes center stage against these CEOs in 2025, whether it’s Brown or a friendlier figure like current member Republican Sen. Tim Scott of South Carolina, will be closely watched.

Some voters will also have a chance to express their opinions on cannabis on Tuesday.

Voters in Nebraska, North Dakota, South Dakota and Florida have marijuana measures on the ballot. And voters in Massachusetts may decide to go further and possibly legalize psychedelics.

For example, the Florida bill would legalize recreational marijuana use for all adults in the state. It is already legal in Florida for medical reasons and is already known as the most lucrative medical cannabis market in the US.

The results in Florida and elsewhere would further add to a patchwork of marijuana laws across the country and could also determine whether the long-awaited changes nationally are closer to reality.

Efforts to legalize cannabis banking have long been stalled in Washington DC, while the SAFE Banking Act has been stalled in Congress for years. But increasing acceptance at the state level of “legitimate” cannabis-related businesses could further open the door for these efforts.

The battle for control of Congress could last as long overall as the presidency — and could be just as important on certain issues.

Two of the most important debates in Washington in 2025 will be about taxes and green energy. In either case, a President Trump or Harris could see nearly all of their promises on these fronts flounder as they negotiate with a House or Senate controlled by the opposition party.

“The composition of Congress is critical,” said Charles Myers, chairman and founder of Signum Global Advisors, in a recent interview on tax issues.

He said a divided Washington is the most likely outcome and will quickly lead to a massive lowering of expectations regardless of who wins.

A split decision seems very possible indeed. According to a consensus forecast from 270toWin, Republicans are able to win at least 51 seats and thus retain control.

In the House of Representatives, the division is even, with 21 seats up for election that will likely decide who will wield the gavel next year.
