Real estate and business honchos dumped $1.3 million into Mayor Adams’ war chest over the last six months, campaign finances records posted Monday night reveal.

The first-term Democrat — who sources argue has ambitions to one day seek the presidency — now has $2.6 million at his disposal ahead of the 2025 elections, according to the New York City Campaign Finance Board.

Around 360 individual donors gave Hizzoner the maximum donation of $2,100, which is the maximum amount able to be donated in a non-election year to participants in the city’s public campaign finance system.

Among the real estate big wigs who gave the maximum donation were Alexander Durst, chief development officer at commercial real estate company the Durst Organization, David Falk, president at development company Newmark Knight Frank and SL Green Chair and CEO Marc Halliday and founder Steve Green.

SL Green is represented by Adams’ former chief of staff Frank Carone and in the running to put a casino in Times Square with Caesars Entertainment and Roc Nation’s Jay-Z.

Howard Fensterman, a partner to Carone’s firm Abrams Fensterman, LLP, and his wife Lori also each gave the maximum donation, records show.

Carone’s brother Anthony, who is a partner at the firm, also forked over the most cash allowed under the law to the mayor.

More than half a million dollars worth of Adams’ contributions came from outside the city, including contributions from Grubhub CEO Adam DeWitt, who is based in Chicago.

During the first six months of the year, Adams’ campaign had about $213,000 in expenditures, according to the statement.

Adams’ single biggest expenditure of the 2025 cycle was to Broadway theater group, Jujamcyn Theaters, which his campaign paid $75,000 to hold a fundraiser there.

His campaign also cut one of Hizzoner’s favorite dining spots, La Baia, a $1,000 check for ‘meet and greet’ in March 2022.

Adams had previously spent campaign cash on out-of-state fundraisers and a stay at the famed Beverly Hills Hilton, where the Golden Globes are typically held, in May 2022.

That same year his campaign paid for at least 14 plane tickets on American Airlines, Delta, JetBlue and United, records show, fueling speculation about his national political ambitions.

Adams fundraising drive comes when no other candidates have declared their intentions to run for City Hall in 2025.
