LA Mayoral Election: First Round Winner?

Platform comparison

Active sub-markets

Market context

Los Angeles will hold its mayoral election on 2 June 2026. If no candidate secures an outright majority in the first round, a runoff between the top two finishers will occur on 3 November 2026. The market resolves on the first-round winner—the candidate with the most valid votes cast on election day, regardless of whether that represents a majority. Tied candidates are separated alphabetically by surname.

The 75% implied probability of a first-round winner reflects historical patterns in Los Angeles municipal elections. In 2013, Eric Garcetti won with 53.6% of the vote in the initial round; in 2005, Antonio Villaraigosa secured 59% without a runoff. However, 2001 saw James Hahn forced into a runoff after winning only 34% of a fragmented field. The outcome hinges on field size and vote distribution. A crowded primary with multiple credible candidates—particularly if no incumbent runs or the incumbent is weak—increases runoff probability. Current market depth suggests sufficient deposit flow through SEPA and USDC rails to support active position-taking, though traders should monitor whether major candidate announcements trigger liquidity shifts.

Key catalysts include formal candidate registration deadlines and campaign finance disclosures, which typically drive information updates in the months preceding June 2026. Polling releases from local media outlets and the Los Angeles Times will shape probability adjustments. Withdrawal mechanics remain standard across major on-ramps; traders should verify fee structures for their chosen deposit method before committing capital.

Methodology

We track LA Mayoral Election: First Round Winner? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

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.
