Josh Kraft filed paperwork with the state’s Office of Campaign and Political Finance (OCPF) last Friday that now permits him to begin raising — and spending— money to fund a race for mayor of Boston.

It is the first official indication that Kraft, who has not yet made any public statements about his intention to run, will in fact challenge incumbent Mayor Michelle Wu in the municipal election later this year. Wu has already said she plans to seek a second term.

In the filing, posted Monday on the OCPF website, Kraft lists his home address on Battery Wharf in the North End of Boston. His chairman and treasurer is identified as Allison Murray, who works for CFO Compliance, a firm based in Providence, R.I. He lists his party affiliation as Democratic, though mayoral contests in Boston do not involve party primaries.

A son of the New England Patriots owner, Kraft is president of the New England Patriots Foundation and is responsible for the family philanthropic initiatives such as the Patriots Foundation, the Revolution Charitable Foundation, and the Kraft Center for Community Health. He previously spent 30 years with the Boys & Girls Clubs of Boston.

Wu was elected mayor in 2021 with about 64 percent of the vote and has said she intends to seek reelection this year but has not formally kicked off her campaign. Councilor Ed Flynn of South Boston had been considered a potential mayoral contender but he said earlier this month that he plans instead to seek reelection to the City Council.

Kraft also serves on the boards of Brandeis University, Brigham and Women’s Hospital, and the Herren Project, and is a co-chair of the Hate Crimes Task Force for Massachusetts, according to his bio on The Kraft Group's website.
