Los Angeles Mayor Election Odds: Karen Bass At 64¢ Vs Nithya Raman

The Los Angeles mayor election odds are a live argument, not a settled score. On Kalshi's winner market, incumbent Karen Bass trades at a 63-cent bid against a 64-cent ask, an implied probability of roughly 64%, while City Councilmember Nithya Raman sits at 35 to 36 cents ahead of the November 3, 2026 runoff. On a board where the California governor race trades at 96 cents as of August 11, a 64-cent incumbent is the closest thing the election slate has to a real decision. And this specific market has already been tested once this cycle, on primary night in June, when it briefly had the wrong candidate advancing. That story is below, and it is the reason to hold today's price loosely.

The Quick Answer

Kalshi prices Karen Bass at about 64% to win the 2026 Los Angeles mayoral runoff, with Nithya Raman at about 35%, in a market that has traded roughly 90.8 million contracts across ten listed names. About 69% of that volume sits on names whose Yes side went to zero when the June primary cut the field to two Democrats. The full volume board, the primary-night whiplash that should discipline how much you trust the current price, and the fee math that sets your effective odds are all below.

The Market At A Glance

Two mechanical notes worth a DFS player's attention before the story. First, the depth: at roughly 90.8 million contracts, this board has out-traded even the California governor market's 49.8 million. Second, the pricing is tight: the two asks sum to exactly 100 cents and the bids to 98, so the quoted prices convert to probabilities essentially at face value, no de-vig pass required. What the raw numbers cannot tell you is how the board got here, and that is where the market earned a scar.

The Primary That Rewired The Board

Los Angeles runs a two-round system: a June primary, and a November runoff between the top two if nobody clears 50%. On June 2, 2026, nobody did. Bass finished first with 34.3% of the vote. The fight for second is the part traders should remember. On election night, reality-TV personality Spencer Pratt, who lost his home in the January 2025 Palisades fire and ran hard against Bass's handling of it, sat second at about 29%, with Raman back near 23%, and traders priced a Bass versus Pratt runoff as the likely outcome. Then Los Angeles did what it always does: it kept counting. Late-arriving mail ballots in LA lean more progressive than the election-day count, and as the tallies rolled in over the following days, Raman climbed past Pratt and finished at 29.0% to his 25.5% in the county's official count, nearly 30,000 votes clear of a candidate the market briefly had advancing, a swing of roughly six points from the election-night gap. Within the week, Kalshi settled Pratt's market to No along with seven other listed names, including a market on Rick Caruso, who never entered the race at all.

That sequence is the whole lesson of this page in miniature. A price built on a partial count is a projection built on three innings of a box score. The market was not wrong to move on election night; it was wrong to be confident. Anyone who has watched an early GPP leaderboard reshuffle by morning already has the right instincts here, and our guide to what actually transfers from DFS to prediction markets maps that instinct onto boards like this one in both directions.

The Volume Board Reads Like An Ownership Table

The primary settled eight of the ten listed markets, and the money that died with them tells its own story.

All ten markets under event KXMAYORLA-26. The eight settled names closed the week after the June 2 primary; Kalshi listed markets on several figures, like Rick Caruso, who never made the June ballot.

The row that matters is the top one. The volume leader on this board is not the favorite. Raman's contract has traded about 14.5 million contracts to Bass's 13.7 million, and Raman holds more open interest too, about 5.1 million contracts to Bass's 4.9 million. That is the same shape we found on the California governor board, where the 4-cent underdog out-traded the 96-cent favorite: volume concentrates where the argument is, not where the equity is. It is the ownership lesson in cents, the same way the most popular stack on a slate is rarely the one with the best win equity, which is exactly the gap our MLB DFS projections, ownership, and stacks in the DataHub exist to measure. And roughly 62.6 million contracts, 69% of everything ever traded here, sits on names that resolved No: the Yes side of those books went to zero, the No side collected, and the board keeps the receipt visible in a way a tournament lobby never does.

Chalk And Leverage At 64 Cents

With eight names cleared away, what remains is a clean two-way portfolio decision between two Democrats.

Bass at 64 cents is soft chalk. In sportsbook terms the ask converts to about -178: a meaningful favorite, nowhere near a lock, and down two cents from the previous close at 66. The case for the price is structural. She is the incumbent, she led the primary by just over five points, and runoffs reward the candidate with the broadest name recognition. The case against overpaying for it: the last major independent survey before the primary, a UC Berkeley IGS poll for the LA Times fielded May 19 to 24, tested this exact head-to-head and had Raman ahead of Bass, 32 to 28, with 15% undecided and a quarter of respondents saying they might not vote at all. A pre-primary hypothetical is not a runoff forecast, but a favorite who trailed the only public test of the matchup she now faces, and who took 34% of her own primary, is a projection with wide error bars.

Raman at 35 to 36 cents is the leverage side, about +178 at the ask. She is a sitting councilmember running to Bass's left, she has already beaten a partial-count narrative once, and the same late-mail dynamics that rescued her in June will shape how November's count reads in real time. The number I keep coming back to is open interest: about 5.1 million contracts still open on the Raman book against 4.9 million on Bass's. Open interest is symmetric, every open Yes is matched by an open No, so it does not tell you which side is right; it tells you how contested a book remains. By that reading this race sits somewhere between the Texas Senate market that trades as a near coin flip and a settled 96-cent coronation, with far more unresolved argument than any other big race on the board. We do not publish trade recommendations on these pages either way; the point is that a 64-35 market is one where your own read of the fundamentals can actually disagree with the price, the same way we run our own projections against market-based numbers in the prop tools rather than trusting either alone.

How A Contract Price Becomes A Probability

The translation layer, for readers newer to event contracts than to lineups: a Yes contract pays $1 if the outcome happens and $0 if it does not, so a price in cents reads directly as an implied probability. A 64-cent Yes is a 64% market estimate. Two adjustments refine the raw read:

1. The spread. Bass's midpoint (63.5) plus Raman's (35.5) sums to 99.0 cents, just under a full dollar, so there is no bookmaker-style overround to strip out; normalized, the pair lands near 64% and 36%. A sportsbook two-way at typical hold runs 104 to 105 cents on the same math, which is why exchange prices convert almost at face value while sportsbook lines need a de-vig pass. Our Kalshi versus DFS pick'em apps comparison shows the same face-value property on sports props.
2. Fees. Kalshi's standard taker fee is 0.07 times price times one minus price, per contract, which peaks near the middle of the price range, right where this market lives:

Unlike a 96-cent market, where fees round to noise, a mid-priced two-way like this one pays close to the maximum toll, so the effective odds sit noticeably worse than the screen price on both sides.

A Worked Example: Two 100-Contract Orders, Fees Included

Walk both sides at the August 11 asks. One hundred Bass Yes contracts at 64 cents cost $64.00, plus a taker fee of 0.07 x 100 x 0.64 x 0.36, which Kalshi rounds up to $1.62. If Bass wins in November, the position pays $100.00, a profit of $34.38 on $65.62 committed, about 52% over roughly three months; if she loses, the full $65.62 is gone. One hundred Raman Yes contracts at 36 cents cost $36.00 plus the same $1.62 fee; a Raman win pays $100.00, a $62.38 profit on $37.62 committed, about 166%, and a Raman loss costs the full $37.62. Notice what the fee did: it moved Bass's breakeven from 64% to about 65.6%, a real haircut in a market this close. On a 96-cent contract that adjustment is a rounding error. At 64 cents it is the difference between buying the market's number and paying a premium over it.

What Moves This Before November 3

Three catalysts are worth a standing watch. First, fresh head-to-head polling: the only major public test of this matchup, the May Berkeley IGS survey, had Raman ahead 32 to 28, so the first credible post-primary surveys will either validate the market's structural read on the runoff or blow a hole in it. Second, the price history itself: about 1.1 million Bass contracts changed hands in the past day against roughly 240,000 for Raman, and the two-cent move came out of Bass's price, so the active side of the book right now is the one repricing the favorite. Third, count dynamics on election night: June proved this market will trade hard on partial returns and that the late-mail lean can flip the story, so the sharpest November read may simply be patience while others chase the first tally.
