Karen Bass is the incumbent mayor running for reelection. Kalshi has her at 56% to win the seat. Behind her, the same market prices Spencer Pratt at 27% and Nithya Raman at 16%.
The June 2 primary is the trigger, but the contract doesn't actually resolve until the office is filled, which means a Pratt YES bet requires him to clear three separate gates: survive the June primary, make the November runoff, and then beat a sitting Democratic mayor in a Democratic city.
The market is pricing him like the first gate is the only one that matters.
That assumption is doing a lot of work, and it falls apart the moment you look at the actual data on the race. Three separate pollsters using three different methodologies have polled this race in the last two months. None of them get very close to 27%.
| Poll | Dates | Sample | Bass | Pratt | Raman |
|---|---|---|---|---|---|
| Emerson / Inside CA Politics | May 9-10, 2026 | 350 LV (±5.2) | 30.2% | Low twenties | Mid-teens |
| UC Berkeley IGS / LA Times | Mar 9-15, 2026 | full sample | 25% | 14% | 17% |
| UCLA Luskin | Mar 15-29, 2026 | full sample | 25% | 11% | 9% |
The market has Pratt at nearly double his best polling number, and the gap has been open for weeks. Either every credible pollster covering this race has missed a structural shift in the electorate, or the market is overreacting to something that isn't real. We think it's the latter, and we think the trade is buying Pratt No at 74¢.
Why the Pratt Number Is Wrong
"Sure, the polls disagree with the market. But polls have been wrong before.”
There are three independent pieces of evidence all pointing in the same direction.
The crosstabs are brutal. Emerson has Pratt at 30% with men and 6% with women. That's a 24-point gender gap, which is the kind of split you see with novelty candidates who go viral with a specific demographic and never broaden.
His support skews young men under 40, while older voters, the ones who actually show up in June primaries, break heavily for Bass. A candidate whose coalition is exactly the demographic least likely to vote in a low-turnout primary is not a candidate who should be polling at 27%
The money tells the same story. Through April 18, Pratt had raised $538K and was sitting on $315K in cash on hand. Bass had $2.26 million in cash. Raman had $960K. Even Adam Miller, who isn't even priced on this market, had more cash on hand than Pratt.
The math of converting viral attention into actual votes requires paid media in the final weeks, and Pratt's bank account doesn't support a sustained finishing kick. Without an ad blitz in May to convert online sentiment into low-information voter awareness, the demographic ceiling holds.
The institutional support doesn't exist. Bass has Kamala Harris, Senator Alex Padilla, and the AFM Local 47 musicians' union backing her campaign. Pratt has nothing of comparable weight. Even DSA Los Angeles, which is the natural home for a left-wing protest candidacy, publicly declined to endorse anyone in March.
A media moment is the entire reason the market is at 27%. After last week's debate, an online viewer poll declared Pratt the winner. The market repriced as if a sentiment shock from an unscientific online poll meant the same thing as actual voter movement, very far fetched.
The Trade
Buy Pratt No at 74¢. One contract pays 26¢ on every outcome except Pratt actually winning the LA mayor's office.
| Outcome | P&L |
|---|---|
| Bass wins outright in June | +26¢ |
| Bass wins November runoff | +26¢ |
| Raman wins | +26¢ |
| Field/other wins | +26¢ |
| Pratt wins | -74¢ |
Five of six paths pay. The one that doesn't is the one the polls, the cash, and the runoff logistics all argue against.
The Risk Factors
In my opinion, the trade really only has 1 real way to fall apart, and another tail risk worth noting.
The main risk: Pratt is actually able broadens his coalition. Maybe he has another viral debate moment, or a Bass scandal at the wrong time, or a national endorsement from someone with reach could bump his odds very fast. But the reason to exit the position will be easily noticeable, if a credible May or June poll puts Pratt clearly ahead of Raman and within striking distance of Bass, exit the position.
But the key is to watch the underlying demographics of the poll, not the toplines. A top-line number that shows Pratt rising without a significant shift in his gender or age splits is very likely just noise. A top-line number alongside a closing gender gap is a genuine signal that his coalition is broadening, and he becomes a real threat to Bass.
The underrated risk: Bass implosion. Berkeley already had Bass at 56% unfavorable and 31% favorable before this race even started. The Palisades fire criticism stuck and the MacArthur Park federal raid did not help. A late scandal helps Pratt more than Raman because Pratt is the protest vote, and protest votes can gain momentum fast when the incumbent is wounded or weakening. This is a tail risk, not a base case, but it's worth tracking.
The Bottom Line
Pratt at 27% is the mispricing here, with three polls capping him in the mid-teens to low twenties %. His cash on hand is a third of Raman's, and his coalition is the worst possible fit for a potentially low-turnout June electorate, all while a YES payout requires beating Bass in a November runoff he has to even make first.
They may be getting fooled by a viral debate moment and a low credibility online poll, and it hasn't repriced even though the evidence against Pratt has been visible for weeks.
Buy Pratt No at 74¢, exit if a credible poll puts Pratt clearly ahead of Raman with closing gender and age splits.
