Billionaire former New York City Mayor Michael Bloomberg has poured another $1.5 million into a super PAC supporting Andrew Cuomo’s independent bid for mayor — a late-stage intervention aimed at halting Democratic socialist Zohran Mamdani ahead of Tuesday’s election.
Filings show Bloomberg’s donation went to Fix the City, a Cuomo-aligned committee that has spearheaded anti-Mamdani advertising and voter outreach in the campaign’s closing days.
The super PAC has raised more than $7.3 million since the June primary, according to Business Insider.
Bloomberg’s latest contribution brings his total spending on Cuomo’s behalf to $9.5 million, making him by far the largest financial backer of the former governor’s comeback campaign.
Bloomberg previously spent $8 million on the pro-Cuomo super PAC during the Democratic primary, when the former governor lost to Mamdani by nearly 13 points.
“Being mayor of New York City is the second toughest job in America, and the next mayor will face immense challenges,” Bloomberg said on Wednesday.
“Andrew Cuomo has the experience and toughness to stand up for New Yorkers and get things done.”
The donation and public endorsement come after hundreds of thousands of early ballots have already been cast.
A Quinnipiac University poll released Wednesday found Cuomo narrowing the gap with Mamdani, whom he now trails by 10 points. Republican nominee Curtis Sliwa still trails in third place.
Following Mamdani’s upset primary victory, Bloomberg met privately with the assemblyman at his Midtown headquarters in September.
Advisers to both men described the conversation as “candid and productive,” but Bloomberg ultimately reaffirmed his support for Cuomo.
The 83-year-old media mogul’s late endorsement is viewed as a sign of panic spreading among New York’s business and donor elite over Mamdani’s proposals to tax the ultra-wealthy and expand public services.
Mamdani has called for an additional 2% tax on New Yorkers earning more than $1 million a year — a move opponents say would accelerate the flight of wealthy residents.
Despite those warnings, Mamdani continues to lead in public polling, fueled by younger voters and progressives who view him as a clean break from the city’s political establishment.
An analysis by Fortune found that at least 26 billionaires and wealthy families have funneled six-figure sums into PACs supporting Cuomo or opposing Mamdani, totaling more than $22 million.
Along with Bloomberg, the biggest contributors include hedge fund manager Bill Ackman, Airbnb co-founder Joseph Gebbia and the Lauder and Tisch families.
Ackman has donated $1.75 million to Fix the City and a separate group, Defend NYC, which has raised roughly $2.5 million. Gebbia contributed $2 million across several committees. Other donors include billionaire developers Barry Diller, Steve Wynn and Daniel Loeb, as well as Walmart heiress Alice Walton.
The 34-year-old Queens assemblyman has championed a platform of higher taxes on the rich, city-funded grocery stores and free bus service — proposals that have alarmed the financial and real estate sectors.
Bloomberg, who amassed a $110 billion fortune through his namesake media and financial-data empire, has long clashed with New York’s left wing.
A former Republican-turned-independent-turned-Democrat, he spent much of his mayoralty sparring with public unions and progressive lawmakers over education, housing and policing.
During Cuomo’s earlier tenure as governor, the two men were frequent rivals, with Bloomberg opposing several of Albany’s tax and labor policies at the time. But their mutual distaste for the Democratic Party’s far-left flank has brought them together in this year’s mayoral race.
Cuomo, who stayed in the contest as an independent after losing the Democratic nomination, has embraced support from business leaders while portraying himself as a centrist bulwark against what he calls Mamdani’s “reckless socialism.”
His campaign has leaned heavily on Fix the City’s negative ads, which accuse Mamdani of endangering jobs and public safety.
