Market context
The next Los Angeles mayoral contest is a real-world election for the city’s top job, and in this market a **YES** share pays out if the named outcome happens before the settlement window closes, while a **NO** share pays if it does not. Here, the question is whether the eventual winner of the 2026 race is the specified candidate, with the market resolving to credible reporting first and, if needed, the City of Los Angeles’ official result. [9][16]
A crowd-implied probability of **64%** suggests traders see the outcome as more likely than not, but not close to certain. That fits a race that has already been framed as competitive: Karen Bass, the incumbent, and Nithya Raman advanced from the primary, while Spencer Pratt was eliminated; the first-round tally showed Bass on 34.3% and Raman on 29.0%, leaving the runoff as the decisive contest. In prediction-market terms, the price is a snapshot of how likely the market thinks the candidate is to win the runoff, not just to perform well in the primary. [1][7][13]
Traders should watch runoff campaign moves, endorsement shifts, and any official updates from the City Clerk or Registrar-Recorder as November approaches. Recent reporting has highlighted the main fault lines in the race: recovery from the 2025 wildfires, homelessness, and federal immigration enforcement, alongside Bass’s incumbency and Raman’s progressive challenge. ABC News reported that Bass, Raman and Pratt emerged as the main frontrunners before the primary, and the city’s official general election date is 3 November 2026, so any change in the field or the final certified count could move the market sharply. [2][7][9][10]
Methodology
Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.
Resolution & payout
Settlement runs on-chain. Polymarket's contract logic separates YES and NO shares as conditional tokens; at resolution the winning share lifts to $1.00 and the losing one to $0. The outcome input comes from the UMA Optimistic Oracle, which secures against bad resolution with a bond + dispute window.
Once finalised, the smart contract pays USDC to the holders' wallets within minutes — no withdrawal fees beyond Polygon network gas. Kalshi settles in USD via CFTC clearance, Betfair in account currency net of commission, Manifold in play-money mana with no cash-out.
