S&P 500 (SPY) closes above … on July 13?

Platform comparison

Market context

The S&P 500 will close on 13 July 2026 at some price level, and this market asks whether SPY—the SPDR S&P 500 ETF Trust tracking that index—will finish above a strike price set by the market creator. On Polymarket, this contract settles via conditional tokens on Polygon, with USDC collateral backing both YES and NO positions. The 0% crowd probability reflects either an extremely high strike price relative to consensus forecasts, or insufficient liquidity to establish a meaningful bid-ask spread. Traders holding YES tokens would profit if the closing price exceeds the threshold; those short YES (holding NO) profit if it closes at or below.

Historical precedent suggests SPY strike prices set far above current spot values rarely attract trading volume. During the 2021–2022 bull-to-bear transition, markets priced out-of-the-money calls at near-zero probability when strikes exceeded realistic twelve-month targets by 15–20%. The current 0% reading likely indicates a similar gap between the strike and analyst consensus for mid-2026 valuations. SPY closed 2024 near $600, and annualised growth assumptions would place July 2026 fair value in the $630–$680 range under base-case scenarios.

Catalysts through settlement include Federal Reserve policy decisions (June and July 2026 meetings), second-quarter earnings season (late July), and any macroeconomic shocks affecting equity risk premiums. Treasury yield movements, inflation data, and corporate guidance will shape whether the index approaches or retreats from the strike. Traders should monitor the VIX term structure and options-implied volatility to gauge whether the zero probability reflects genuine market consensus or simply a liquidity desert on an unfavourable contract design.

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.
