Warren Buffett, one of the world’s richest men, sees a woman in the White House in 2016.

Speaking to Carol Loomis at Fortune’s Most Powerful Women Summit, Buffett predicted Hillary Clinton would run and win the presidential race.

“Hillary’s going to run,” the man called the Oracle of Omaha said, after admitting he gave donations to both Clinton and Barack Obama in 2008.

Laughing and drawing applause from a friendly, mainly female audience, Buffett answered a direct question from Loomis about Clinton’s chances.

“Hillary’s going to win, yeah,” he said. “I will bet money on it. I will. I don’t do that easily.”

Buffett, CEO of Berkshire Hathaway, said he had no idea who would be her opponent in the presidential race.

“Her opponent will be whoever wins the Republican primary and there’s going to be a lot of people want to do it,” he said.

Buffett has opposed campaign-finance rules that allow unlimited contributions from individuals or corporations and said he would never give to a super political action committee, which can spend money independently of a political candidate's campaign.
