S&P 500 (SPY) closes above … on July 24?

Platform comparison

Market context

On 24 July 2026, the S&P 500 exchange-traded fund (SPY) will close at some price level. This market asks whether that closing price will exceed a specific threshold—currently blank in the market title, pending the strike price to be filled in by the market creator. In prediction markets, a YES share pays out if the event occurs; a NO share pays out if it doesn't. Here, traders holding YES shares profit if SPY closes above the strike; NO shareholders profit if it closes at or below it. The settlement window closes at 20:00 UTC on that date, after US market close.

The 0% crowd probability suggests either the strike price is set far above realistic valuations for that date, or the market has attracted minimal participation so far. Historical precedent matters: SPY's long-term average annual return sits around 10%, though volatility clusters around earnings seasons and macroeconomic shifts. In mid-2026, positioning will depend heavily on Federal Reserve policy trajectory, inflation data from the first half of the year, and corporate earnings revisions. A strike significantly above the 200-day moving average would naturally attract few YES bets; conversely, a conservative strike would see the probability drift higher as traders recognise the likelihood.

Traders should monitor June and early July 2026 for US inflation reports, employment figures, and any Federal Reserve communications signalling rate changes. Earnings season typically concludes by late July, so most guidance will already be priced in. Geopolitical developments and credit-market stress are wildcards that could shift volatility expectations sharply in either direction ahead of settlement.

Methodology

This page is a comparison snapshot: one live quote, four reference venues with their key attributes, and a single execution path — every trade button routes to Prediction Market UK, which mirrors the Polymarket order book directly.

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.

FAQ

Is this market available outside the US?

Polymarket itself is geo-blocked in the US/UK/EU. Always check the legal status of prediction markets in your jurisdiction before trading.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Prediction Market UK trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
