Steyer's poor showing came after he had made a big play for South Carolina. Results with 85 percent of precincts reporting showed him with just over 11 percent of the vote, below the 15 percent threshold needed to win delegates from the state.

“There’s no question today that this campaign, we were disappointed with where we came out,” Steyer said in his concession speech. “But I said, if I didn’t see a path to winning, that I’d suspend my campaign. And honestly, I can’t see a path where I can win the presidency.”

The philanthropist had poured over $20 million of his own money into South Carolina to fund an advertising blitz, offering competitive campaign salaries and hiring many businesses owned by African Americans, who make up the majority of the Democratic electorate in the state.

However, he was unable to overcome Biden's strong support among African Americans.

Steyer has struggled to stand out in the race, finishing far behind the pack in Iowa and New Hampshire, while notching a fifth-place finish in Nevada.

“I’m not leaving. You may want me out of here. I’m not leaving. We’re already figuring out ways in fact to make sure that we stay in South Carolina,” he said.

Steyer said he still felt vindicated by his campaign, which centered around ending corporate corruption, rectifying racial inequities and advocating for solutions to tackle climate change. He also made term limits for Congress and reparations for African Americans focal points of his White House bid.

“I didn’t get into this race and start talking about things to try to get votes. I was in this race to talk about things that I care the most about and that I continue to care the most about,” he said. “This has been a great experience. I have zero regrets.”
