Harris Raises More Than $50 Million as Biden’s Exit Unleashes Cash Wave

Vice President Kamala Harris raised more than $50 million in less than 24 hours after entering the 2024 race for president, her campaign said, as Democrats welcomed her candidacy with one of the greatest gushers of cash of all time.

Ms. Harris’ take was part of an even larger haul collected through ActBlue, the online donation-processing portal used by Democrats up and down the ballot.

As of Monday morning, ActBlue had processed more than $80 million online in the hours since President Biden announced he was stepping aside, according to a New York Times analysis of the platform’s online ticker of contributions.

The surge of online donations peaked at $11.5 million in a single hour on Sunday evening.

The Harris campaign accounted for the lion’s share of the funds raised online. Her campaign announced that she had raised $49.6 million as of 5 a.m. Eastern time.

The rush of donations came as the party quickly coalesced behind Ms. Harris. The funds will help rebuild a war chest that was at risk of getting depleted in the weeks of uncertainty after Mr. Biden’s poor debate, as big donors paused fund-raising.

Sunday ranked as the third-largest single day in ActBlue’s history. The all-time high came the day after Justice Ruth Bader Ginsburg passed away in September 2020, when ActBlue processed roughly $73.5 million. The second-highest was the date after the first debate between Mr. Biden and former President Donald J. Trump, which coincided with a key fund-raising deadline.

Monday was on pace to be another huge day for donations. In the hours since the Harris campaign’s early-morning announcement, another roughly $10 million had been donated on ActBlue. The ActBlue ticker includes all online donations made on the platform, including
