The Trump-endorsed Sheehy has a lead in a Senate race that could determine control of the chamber.

“You have a very important job to do,” Tim Sheehy, the GOP candidate for Senate in a tight Montana race, told a roaring Bozeman crowd in August. “If Donald Trump gets to the White House and doesn’t have a Senate, he’s not going to get things done—you need to deliver him a Senate by retiring Jon Tester!” Trump took the stage soon after. “I got to like Tim Sheehy a lot to be here, I have to tell you,” the New York-born billionaire said. “He better win.”

Behind the scenes, there are plenty more billionaires who like Tim Sheehy, too—enough to put big bucks behind him. Forbes examined Federal Election Commission records for every group that has backed Sheehy or opposed Tester in the high-stakes race. In all, 12 billionaires have given more than $1 million to those groups since 2023.

Some, like hedge funder Ken Griffin, have donated to organizations that are focused on Montana in particular. In 2023, Griffin sent $5 million to a group called “More Jobs, Less Government” that has poured almost $11 million into defeating Tester as of the latest filings. In May, Griffin cut a $1 million check to the Sentinel Action Fund, a group that splits its cash between Montana and Ohio, another red state with an incumbent Democrat trying to hold onto his seat. (A spokesperson for the group added that they have also been spending on get-out-the-vote measures in Pennsylvania and Nevada, which, unlike ads, do not always appear in the same FEC data.) “Tim Sheehy shares my priorities to promote freedom and deliver real results for hardworking families,” Griffin wrote in a statement to Forbes. “America will be well served if talented leaders and veterans like Tim are elected to serve in the Senate.”

Other billionaires have become big backers of Sheehy because they are major donors to conservative groups that are spending cash all across the country.........
