Ken Griffin, founder of Citadel Investment Group, predicted at the Future Investment Initiative Summit in Saudi Arabia on Wednesday that Trump would be re-elected president of the United States. "The expectation today is that Donald Trump will win the White House in just a few short days. We'll know soon," Griffin said. Griffin also commented on market volatility, suggesting the election result would reduce uncertainty and benefit asset prices. "We're at the most uncertain moment," he said. "It's a race that Trump is expected to win, but it's almost a coin toss."
