NBA: Stephen Curry to leave Warriors?

Platform comparison

Market context

Stephen Curry **not being on the Warriors roster by October 2026** is a low-probability outcome at the market’s current **4% YES** price, with the consensus still firmly on **No**. Curry already has a one-year, **$62.6 million extension** that keeps him under contract through the **2026-27 season**, which is the central reason this is priced as a heavy favourite for the team to keep him listed on the official roster. [2][11]

The historical frame also points towards persistence rather than separation: Curry has spent his entire NBA career with Golden State, and the latest extension was explicitly designed to carry him beyond the upcoming season boundary. Comparable late-career superstar markets usually only reprice sharply when there is a clear contract, health, or retirement signal; absent that, the implied path is that he remains rostered unless there is an unexpected trade, release, or retirement decision. [2][4][9]

For traders, the main catalysts are roster-adjacent rather than performance-related: any retirement hints, trade chatter, or a surprise change in Golden State’s direction ahead of the 2026-27 season would matter most, because the market resolves on official roster status, not games played. The latest reporting around Curry and the Warriors has instead emphasised mutual interest in keeping him and the broader expectation that he stays tied to the franchise, which leaves the contrarian value angle on **Yes** dependent on a relatively narrow set of late, non-performance developments.

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.

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.
