Boston mayoral candidate Josh Kraft – due to officially launch his challenge on Tuesday – faces a glaring potential conflict of interest in  his family’s bid for a new professional soccer stadium in Everett.

Kraft, son of Patriots owner Robert Kraft, says he is “not involved” in the family’s soccer business but will have to disclose soon whether he has a personal financial stake in the 25,000 seat stadium and how he will represent the city in tough negotiations with the Kraft family.

Emails obtained by the Herald on Monday detailed the chilly and distrustful relationship between the Kraft Group and the Wu administration and the Krafts’ woeful offer of just $750,000 in traffic and parking mitigation to the city.

“The city has reviewed the Kraft Group’s initial offer of $750,000 in mitigation and finds it unacceptable as a starting point for discussion,” Kairos Shen, Boston’s chief of planning, wrote in a Jan. 22 email to New England Revolution President Brian Bilello.

Shen’s Jan. 22 response was sent a day after sources confirmed to the Herald and other media outlets that Josh Kraft had decided to enter the 2025 mayoral race against incumbent Michelle Wu.

That offer of $750,000 is a drop in the bucket for the ultra wealthy Kraft family and the city is right to reject it.

Shen’s email also references Wu’s longstanding position, that Boston was excluded from the process to bring a new stadium to Everett, despite the traffic and other impacts that would be felt by the city, particularly in nearby Charlestown.

Josh Kraft is in charge of the family’s philanthropic activities but it is not clear whether he has a financial stake in the Kraft Group’s for-profit ventures like the Patriots and New England Revolution.

He should disclose immediately whether he does have a conflict in negotiations over the soccer stadium in Everett.

How can he possibly represent the city’s interests when dealing with his own family’s team?

And as mayor, how can residents in a neighborhood like Charlestown he hopes to win in the election trust him to represent their interests over the Krafts?

Here are some more questions for Josh Kraft: How do you put a large soccer stadium on a site with no parking? And why didn’t the city of Boston, which will be severely affected by the stadium, have a seat at the table in negotiations?

Several Boston city councilors have already raised concerns about parking and traffic impacts in Charlestown. Will Kraft listen to them?

Will he join Mayor Michelle Wu in opposing the project until the traffic and mitigation problems are addressed?

Kraft is due to officially launch his campaign on Tuesday at 11 a.m. in Roxbury and released a campaign video on Monday outlining his campaign, taking a few shots at the Wu administration. He is expected to take aim at Wu’s top-down style of governing and not listening to residents opposed to her initiatives.

“I’m Josh Kraft,” the 57-year-old first-time political candidate says in the video. “There’s a saying we had at the Boys and Girls Club. I care. I care that Boston is heading in the wrong direction. I care that our region continues to leave many people behind. I care that middle-class families are squeezed by the cost of housing, and I care that City Hall puts politics and ideology ahead of impact.

“That’s why I’m running for mayor,” Kraft said.
