Los Angeles is in a weird phase as residents look toward electing its next mayor, with prediction markets now suggesting reality star Spencer Pratt is more than a sideshow in the race. 

As Mayor Karen Bass seeks reelection, she felt some fierce words from Pratt during this week’s mayoral debate about her handling of the 2025 Palisades fire. 

“I blame this person for burning my house and my parents’ house down,” he said of Bass.

Still behind Bass and City Council member Nithya Raman, who had been leading the markets until this week’s debate, prediction markets are treating Pratt as a seemingly surging contender. This is happening in the shadow of a volatile California governor’s race, where frontrunners keep shifting.

The California political context

The state is in a moment of political volatility, with an open CA governor race featuring a crowded Democratic field and a Republican side that’s still consolidating. 

That volatility has already spilled into local markets, which are now sensitive to any candidate who can say something out of the box and generate social media energy, something Pratt has delivered.

That’s the context for the Los Angeles mayoral race. It’s a national-scale market narrative wrapped around a city‑level contest. The LA mayor seat might become a test case for prediction markets and whether a celebrity outsider can translate online buzz into real-world odds.

The Los Angeles mayor race is now one of the most active local markets on both Kalshi and Polymarket. Total volume on Kalshi alone has surpassed $3.7 million, while Polymarket has crept past $1.2 million

The current midterm odds give a clear but narrow picture of the field:

  • Bass is the incumbent frontrunner, with 42% on Polymarket and around 47% on Kalshi
  • Raman is at 32% on Polymarket, dipping down to 27% on Kalshi.
  • Pratt is trading at 25% on Kalshi and 21% on Polymarket, solidly third place, but within striking distance.

That’s a striking read for a candidate whose day job is reality TV compared to candidates with real political experience.

The recent LA mayoral debate hype

The mayoral debate on May 6, moderated by NBC4 and Telemundo 52, was the moment the market went from weird to real‑time. Pratt delivered a sharp performance that was widely seen as the upset of the night, with conservative commentators and even some left‑leaning analysts noting he exceeded expectations.

During the debate, Pratt attacked Bass over wildfire response, accusing her of “the most dangerous thing that the mayor put us up against” and framing the fire as a product of Bass’s management. The line hit hard in a city still reeling from the fires, and it’s the kind of moment that immediately moves the market needle.

Post‑debate, the markets reacted as well. Raman’s odds plummeted from the high 50s down into the 40s on both platforms. Her debate performance did not sit well with traders. Meanwhile, Pratt’s share held and even inched up, reflecting the sense that the race is tightening.

The incumbent’s lead: Karen Bass

Bass is clearly vulnerable. Heading into the debate, Raman had sizable leads on both major prediction market platforms. 

Still, Bass, the incumbent and the first woman elected mayor of Los Angeles, has the biggest reservoir of support, both in the polls and politically. The New York Times polling tracker shows her leading the field, though not above 50%, which means the race is likely to go to a November runoff as the three candidates split votes.

The market is pricing that same dynamic. Bass is the favorite, but not a prohibitive one, with her odds hovering around the mid‑40s. That’s a sign that traders see her as the strongest baseline candidate but still vulnerable to a late‑surge outsider, which is exactly where Pratt fits, or the conventional challenger.

Reality TV and market dynamics

The real shocker in this story is the Pratt anomaly. He’s a reality TV star who’s been out-funded by Raman and Bass but is still attracting serious attention from traders. 

The Los Angeles Times fundraising data shows that Pratt raised the most money since January 1, and that, combined with his TV‑style performance, has given him a real‑time edge.

The market reflects that edge. Pratt is now trading at greater than 20%, which is enough to make him a plausible contender, not just the butt of a joke. The market is effectively pricing him as the celebrity wildcard, with Bass and Raman as the more conventional frontrunners.
