“The expectation today is that Donald Trump will win the White House in just a few days, we will know shortly,” the billionaire Republican donor said during a panel at Saudi Arabia’s Future Investment Initiative summit.

Griffin has been a major supporter of Republicans over the years and has donated about $100 million to pro-Republican political action committees during this election cycle, Bloomberg reported, citing OpenSecrets. 

While Griffin has donated millions to Republicans especially since 2022, he has notably not donated directly to Trump’s campaign. The billionaire investor has especially focused his donations on candidates in primary races, particularly open primaries, according to Bloomberg reporter Bill Allison. Working through super PACs, Griffin has helped support candidates with business experience or military experience, Allison said. 

While Trump has been gaining in polls and prediction markets, the presidential race is still in a dead heat. With a week left until Election Day, Trump has the lead in prediction markets (where people place bets on the outcome of the election). Yet, polls for the New York Times/Siena College as well as Reuters/Ipsos show Harris with a one percentage point lead over Trump as of Tuesday. 

Controversy over recent racist comments by speakers at a Trump rally in New York City’s Madison Square Garden may have put a dent in the former president’s once-record levels of support among Latino voters. A joke made by comedian Tony Hinchliffe that referred to Puerto Rico as “a floating island of garbage” sparked outrage from Latinos and drew criticism by Puerto Rican celebrities.

In a statement to Fortune, Trump campaign senior adviser Danielle Alvarez said the candidate does not condone the offensive remarks about Puerto Rico.

“This joke does not reflect the views of President Trump or the campaign,” Alvarez said.

The Citadel CEO also said during the panel that markets are uncertain, but that the end of the presidential election will bring clarity, no matter who wins. 

“Big picture, the reduction in uncertainty is almost always positive for asset prices,” he said. “We’re at that moment of peak uncertainty. It is a race that Trump is favored to win, but it is almost a coin toss.”
