Nearly four hours after the polls closed and with about 95 percent of precincts reporting, it appears Lori Lightfoot and Toni Preckwinkle will face off for the city's top office. As of 10:40 p.m., Lightfoot led Preckwinkle by about 7,900 votes.
Lightfoot took to the podium about 9:15 p.m., speaking to supporters about breaking Chicago's so-called political machine.
"As some of you know I've been saying now for the last few weeks that this election's gonna be about whether we resign to the status quo or we resolve to fight for what's right," she said. "This election is about the crumbling machine of the past once and for all and demanding an independent, accountable city hall that serves the people, not the political machine."

Preckwinkle addressed her supporters about an hour later.
"I'm not afraid of big challenges or hard work. I know what it takes to tackle them. And I know how gratifying it is when our efforts bend the arc of history a little closer to justice day by day," she said. "While my opponent was taking multiple appointments in the Daley and Emanuel administrations, I fought the power elites who have been trying to hold this city back for decades."

Willie Wilson also made clear that he is remaining in the race, though he trails Preckwinkle, who is in second place, by more than 28,000 votes with 96 percent of precincts reporting.
"There's no reason to be discouraged yet, because we have a lot more (votes) coming in," he said. "So we're not going to call it yet, because there's so much that's out there."
There were originally 14 candidates vying for the city's top office Tuesday, the most ever to run at once in the city's history.
The mayoral race ended for four candidates - Gery Chico, Susana Mendoza, Amara Enyia and Bill Daley - within about two hours of the polls closing.

Chico was the first to concede at about 8:15 p.m.
The Chico camp was confident early Tuesday, feeling that the campaign's ground game could carry the day despite low voter turnout.
The 62-year-old former mayoral chief of staff and head of the school board, park district and city colleges spent Tuesday making a last-minute push for votes in 11 wards all across the city. Chico kept particularly close tabs on returns from the Southwest and Southeast Sides of the city, where he performed well in 2011's mayoral race, which he lost to Rahm Emanuel.

Mendoza conceded next, at about 8:40 p.m.
"I'm proud that we gave it our best shot," she said. "To everyone who voted for me and even those who didn't: Know that I see you, hear you and I'll never, ever stop fighting for you."
Having lost the mayoral race, Mendoza will return to her role as the state's comptroller.

Enyia stepped to the podium to concede minutes later.
Enyia received several star-powered endorsements over the course of her campaign from Chicago-born rappers Kanye West and Chance the Rapper.

WATCH: Bill Daley addresses supporters
Daley was in third place when he addressed supporters about 9:40 p.m.
"I'm here with an outcome none of us wanted. But because we respect the democratic process, we all must accept it and we will move on," he said, congratulating Preckwinkle and Lightfoot on their victories. "No matter who wins in April, our commitment to Chicago will never end."
