Live market odds

Update (September 29, 2026): The runoff between Mayor Karen Bass and Councilmember Nithya Raman is on November 3, 2026. A Berkeley IGS/Los Angeles Times poll taken September 15-20 had Raman ahead 39% to 28%, with 33% undecided. The market prices further down this page are from August; check the live market for today's price.

The spring value trade paid. Nithya Raman polled 9% in April, advanced out of the June first round, and now trades at 31.1% to be the next mayor of Los Angeles: a 3x repricing of the contract in two months. The Council District 4 urbanist is the underdog half of a two-name November runoff against Karen Bass, and her book is now the deepest single-candidate market on Polymarket's $13.1M LA event.

How she got out of the first round

Raman finished second behind Bass in June, and the margin market settled in the 5-10 point bucket. Close enough to make the runoff a real race rather than a formality. The "Bass and Raman advance to the second round" contract settled YES on $522K of volume; the Bass-and-Pratt pairing, which had drawn $1.6M, settled NO.

That is the field consolidating in her favor. Spencer Pratt, whose candidacy was the single most-traded contract of the cycle at nearly $7.9M, is out. Lindsey Horvath ($1.7M), Rae Huang, Rick Caruso, Adam Miller and Gina Viola all settled NO. Roughly 25 points of first-round vote that went to non-Bass, non-Raman candidates is now unassigned. And the anti-incumbent share of it has exactly one place to go.

Why Raman exists in this race

Raman represents the fraction of the 2022 Bass coalition that has since broken left. Bass ran as a progressive in 2022; criticism from the left over the FY26 budget, police-funding expansion, and city-service cuts created the lane Raman is now occupying.

Raman's resume is the asset: urban planner by training, two-term Council member, coalition built around tenant rights, affordable-housing supply, and public transit. Endorsements from Abundant Housing LA and the Future Urbanist Club. The LA DSA chapter declined to endorse anyone in the primary: a slight blow to her opening positioning.

How prediction markets are pricing Raman

Raman trades at 31.1% on Polymarket with $1.26M of volume on her win contract: more depth than the $737K on Bass's, despite Bass being the 65.5% favorite. That imbalance is informative: the money doing the work is on the underdog side. Kalshi runs the same race through its multi-candidate winner market (kxmayorla-26). The two live prices sum to 96.6%, leaving about 3 points of fee-and-liquidity slack rather than an arbitrage.

Strategy 1: the "ground game" value play

Progressive LA campaigns historically out-perform polling among renters and voters under 35. Demographics traditional pollsters under-sample. Raman already beat her 9% polling average badly enough to make the runoff, which is the cleanest available evidence that the overshoot is real. The open question is whether a 3-5 point turnout edge is enough against a consolidated establishment in a lower-turnout November municipal runoff.

The advancement contract is gone, it resolved YES in June. What remains is the outright win market at 31.1¢, and it is a genuinely different instrument: advancing out of a ten-way field rewarded an intense minority, while winning a two-name runoff requires an outright majority of a smaller, older electorate.

Strategy 2: the left-lane consolidation trade

The first round had 16 names; November has two. For Raman to close a 34-point gap, she needs the entire non-Bass first-round vote plus a slice of soft Bass support. Watch for post-first-round endorsements from organized labor, tenant groups, and the LA Times editorial board. Each functions as a Schelling-point signal that left-leaning voters use to coordinate now that there is no third option.

A single major endorsement (United Teachers Los Angeles, the AFL-CIO LA County Federation) typically moves a progressive-challenger contract 4-8¢ within 48 hours.

Markets under-price grassroots candidates because traditional polls under-sample the voters who actually turn out for them. The discount is the trade.

Leading indicators to watch

1. Labor endorsements: UTLA, the LA County Fed, SEIU 721. Any one of these is a 4-8¢ catalyst.
2. Tenant-organization sign-ons, LA Tenants Union, ACCE, signal a working ground game.
3. Voter registration data in Districts 4, 13, and 14 (high-density renter districts where her coalition concentrates).
4. Where the Pratt vote lands. His candidacy drew nearly $7.9M of volume and settled NO; with him off the ballot, any survey of his voters' second choice is the highest-leverage fall data point for this contract.
5. Bass-side dropoff: in a two-name runoff, any negative Bass headline cycle now pushes left-leaning voters toward Raman or toward staying home, with no third option to absorb them.
6. October 5, when California mails ballots to every registered voter. Raman's coalition is the half of this race most sensitive to how easy voting is.

Frequently asked questions

What are Nithya Raman's LA Mayor odds?

As of August 7, 2026, Polymarket prices Raman at 31.1% to win the November 3 runoff against Karen Bass at 65.5%. Her win contract holds $1.26M of volume versus $737K on Bass's. The underdog book is the deeper of the two on a $13.1M event.

Who is Nithya Raman?

Nithya Raman is an urban planner and two-term Los Angeles City Councilmember representing District 4, now the progressive challenger to incumbent Karen Bass in the November 2026 runoff. Her coalition centers on tenant rights, affordable-housing supply, and public transit, with endorsements from Abundant Housing LA and the Future Urbanist Club.

How did she get into the runoff?

Raman finished second behind Bass in the June first round, with the margin market settling in the 5-10 point bucket. Because no candidate cleared 50%, LA's top-two rule sent both to November. The 'Bass and Raman advance' contract settled YES on $522K of volume, while the Bass-and-Pratt pairing that had drawn $1.6M settled NO.

Why did her price triple?

She polled 9% in April and traded 10-18¢ through the spring, when markets index heavily on establishment endorsements that Bass has. Advancing out of a 16-name field on far better than her polling average is the cleanest available evidence that progressive LA campaigns out-perform polls among renters and voters under 35, demographics traditional pollsters under-sample. The market repriced accordingly.

Is her runoff-advancement contract still tradable?

No, it resolved YES in June. What remains is the outright win market at 31.1¢, and it is a genuinely different instrument: advancing out of a ten-way field rewarded an intense minority, while winning a two-name runoff requires an outright majority of a smaller, older November electorate.

What's the 'left-lane consolidation' trade now?

The first round had 16 names; November has two. To close a 34-point gap, Raman needs the entire non-Bass first-round vote plus a slice of soft Bass support. A single major endorsement: UTLA, the LA County Fed, SEIU 721, or the LA Times editorial board: historically moves a progressive-challenger contract 4-8¢ within 48 hours, and does more work now that left-leaning voters have no third option.

What leading indicators should I watch?

Where the Spencer Pratt vote lands, since his candidacy drew nearly $7.9M of volume and settled NO; the first head-to-head public poll; labor endorsements (UTLA, LA County Fed, SEIU 721) and tenant-org sign-ons (LA Tenants Union, ACCE); registration and turnout data in high-density renter districts 4, 13 and 14; and October 5, when California mails ballots to every registered voter.

Is this legal in California?

Available — dispute pending (as of October 13, 2026). Both Kalshi and Polymarket are CFTC-regulated and offer the LA Mayor 2026 runoff contracts to California residents (minimum age 18; we recommend 21+) under federal commodities law. See our California legality guide for the full state regulatory picture.

Which platform has the highest volume for Nithya Raman contracts?

Polymarket is ranked as the number one platform for political volume and typically offers the tightest spreads for local California races. Kalshi is the third-ranked option but offers the benefit of being a US-regulated exchange, providing an additional layer of consumer protection for residents in Los Angeles.

Is there a limit on how many Raman shares I can buy?

Kalshi imposes position limits based on the specific contract and regulatory filings, which can restrict the total exposure a single trader can have. Polymarket does not have formal position limits, though the available liquidity in the order book naturally limits the size of a trade without significant price slippage.
