Pronóstico: SPY (SPY) Up or Down on July 22?

Platform comparison

Market context

SPY is sitting near record territory, so the market is pricing in a modest bias to another higher close rather than a large breakout or reversal. Recent quoted prices have clustered around the mid-740s to high-740s, with one live feed showing 749.08 against a previous close of 748.28 and another putting the ETF at 748.37 earlier in the session.[2][1] That leaves the contract’s 73% implied YES probability broadly consistent with a market that has been trending above its longer-run average, but still leaves room for an intraday fade if the index gives back gains into the close.[5]

The key catalyst is the final cash-session move in the S&P 500 itself, because the contract settles on whether SPY closes above the most recent prior trading day’s close rather than on any intraday high.[2] Traders will be watching whether the ETF can hold above the prior close as the session matures, alongside any late-session macro headlines, Treasury yield swings, or broad equity rebalancing flows that typically hit the tape near the close. Historical context matters here too: SPY’s last reported closing high was 757.62 on 2 June 2026, while the 52-week low was 608.37, so the current level is elevated but not far from the recent peak, which tends to keep one-day direction markets sensitive to small moves rather than requiring a major trend change.[5]

What are live sports odds on Polymarket?

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
