Self-proclaimed socialist Katie Wilson — who is still financially supported by her New York parents at 43 years old — will be the next mayor of Seattle, overseeing a budget close to $9 billion.

Wilson, whose campaign was likened to that of fellow Democratic Socialist Zohran Mamdani in New York City, secured the lead over incumbent Mayor Bruce Harrell on Wednesday.

Unlike the New York City race, however, the Seattle election went down to the wire, with Wilson squeezing just enough votes to win and avoid an automatic recount.

“This campaign was driven by a deep belief that we need to expand the table to include everyone in the decisions that impact their lives,” Wilson said in a victory statement. “That is what we will be working to do every day as we set up this new administration.”

Wilson secured her win by advocating for progressive proposals, including introducing city-run grocery stores and taxing the rich. She also vowed to “Trump-proof” the city.

“Yes, I am a socialist,” Wilson said earlier this year.

“I’m not out here waving a socialist flag, because I’m not a super ideological person. I’m also not sure that label will help me in the general election. But yes, I’m fine with being called a socialist,” she added.

The 43-year-old, who moved to Seattle in her 20s with her now-husband, admitted last month that she relies on her parents, both New York professors, to help with childcare expenses.

The money goes toward day care for Wilson’s 2-year-old, which costs $2,200 per month, she told KUOW.

Wilson also dropped out of college just six weeks before graduation — but debt-free, thanks to her generous parents, the outlet said.

She attended the elite University of Oxford in England.

She will now lead the major US city, overseeing 41 departments and a budget of nearly $9 billion.

Wilson’s win led to a sweep of Seattle’s incumbents — with the mayor, city council president, and city attorney all ousted for left-leaning progressives.

Harrell, who has not officially conceded the race, was expected to address the city on Thursday.

While Harrell lost by enough votes not to trigger an automatic recount, it’s still close enough for his campaign to request and pay for one.

The race in Seattle marks the second win for socialists this month, following New Yorkers’ election of Mamdani last Tuesday.
