Despite lagging well behind “Mayor Pete” in the delegate hunt in Iowa, former Vice President Joe Biden appears to be growing his status on Wall Street.

Biden has raised $1.7 million from Democratic donors within the securities and investment industry, while Pete Buttigieg — another Wall Street favorite — is second with $1.4 million based on federal election data through Feb. 3, according to the Center for Responsive Politics.

At least some of Biden’s lead may be due to a highly anticipated Feb. 13 fundraiser that’s being sponsored by Wall Street bigs, including billionaire hedge funder and Milwaukee Bucks co-owner Marc Lasry, Centerview Partners co-founder Blair Effron and Evercore Partners founder Roger Altman, according to a copy of the invite seen by The Post.

Biden’s campaign team Wednesday told some top Wall Street donors that they expect to raise between $1 million and $1.5 million at the New York City fundraiser, the location of which has not yet been disclosed.

Buttigieg, the former mayor of South Bend, Ind., had been Wall Street’s lead fundraiser as of Sept. 30, with $1 million from securities industry donors, compared to $982,000 for Biden, the Center for Responsive Politics’ data shows.

And earlier this week, he led the Iowa caucus with 26.23 percent of the state delegate count to 26.06 percent for Bernie Sanders. Biden came in fourth with 15.8 percent, trailing Sen. Elizabeth Warren, who captured 18.2 percent.

“We’re behind Biden and Bloomberg at the same time,” one Wall Street Biden supporter said, referring to former Mayor Michael Bloomberg, whose news company sells terminals to Wall Street.

Bloomberg — who is worth an estimated $61 billion — hasn’t yet tried to raise money from Wall Street.
