Katie Wilson will be Seattle's next mayor, having garnered a mathematically-insurmountable lead over Mayor Bruce Harrell, according to the latest ballot tally. Wilson has a 1,976 lead over Harrell, more than the number of remaining votes to be counted.

Harrell’s office announced an address to the people of Seattle to take place on Thursday, which is likely to be the moderate Democrat's concession speech.

Wilson was originally down by 7 percentage points on Nov. 4 but closed the gap as the days rolled on until she eventually took the lead on Nov. 7.

Wilson, a progressive, is the co-founder and executive director of the Transit Riders Union, an advocacy group focused on public transit, as well as issues like affordable housing and stronger renter protections. She announced her intention to run for the Seattle lead in March after seeing recent voting trends pointing to Seattle residents being concerned about a lack of delivery on voters' top concerns over the last four years, signaling a need for change of city leadership.

Prior to the latest election results on Wednesday, the Wilson campaign told The Center Square it was confident she had won the race.

“Ahead by almost 2,000 votes, we now believe that we’re in an insurmountable position,” Wilson’s campaign stated in a social media post. “We look forward to hearing the mayor’s address to the city tomorrow.”

Wilson – who has not shied away from comparisons to New York City Mayor-elect Zohran Mamdani, a democratic socialist – ran on platforms that include more affordable transit for riders, more progressive taxes, stronger renter protections, and universal child care.

In her first year as Seattle mayor, Wilson will be tasked with handling a major sporting event: FIFA World Cup qualifying matches, which is anticipated to bring in 400,000 to 750,000 visitors, as well as continuing issues facing Seattle residents like affordability, homelessness, and public safety.

Wilson, 43, has never held an elected office before.
