Dave Portnoy Says Donors Approached Him to Run Against NYC Mayor Mamdani
Unverified offers of campaign funding, if formalized, would immediately trigger New York City and federal disclosure requirements — and no filing has yet appeared in public records.
Barstool Sports founder Dave Portnoy stated on the July 10, 2026 episode of the Business of Betting podcast, hosted by Jeff Edelstein, that multiple individuals he described as billionaires have approached him unsolicited with offers to fund a potential mayoral campaign against New York City Mayor Zohran Mamdani. Portnoy said the offers came from 'serious people' and that, if he chose to run, he could assemble what he called 'the biggest war chest probably in the history of political war chests.' The statements were made publicly on the podcast and reported by the New York Post on July 16, 2026.
As of publication, no campaign committee for Portnoy has been registered with the New York City Campaign Finance Board (CFB), which requires disclosure of contributions and expenditures for covered New York City elections. A search of the CFB's public database — available at nyc.gov/cfe — returns no active filing under David Portnoy or any known affiliated entity as of today's date.
New York City's next mayoral election is scheduled for November 2029. Under New York City Campaign Finance Act rules, formal fundraising triggers mandatory disclosure once a candidate establishes a committee or receives or spends funds in connection with a covered election. Federal campaign finance law would not apply to a purely municipal race, but any political action committee activity at the federal level would require disclosure with the Federal Election Commission.
Mayor Mamdani took office in January 2026 following his victory in the November 2025 general election, in which he defeated the Republican nominee. His campaign's final financial disclosures are on file with the New York City CFB. The total amounts raised and spent by both major candidates in that race are a matter of public record in those filings.
What remains unknown is the identity of the individuals Portnoy referenced, whether any written commitment or transfer of funds has occurred, and whether any entity has been organized to support a potential candidacy. The New York City Campaign Finance Board's public disclosure portal and any future FEC filings would be the authoritative records to answer those questions.
