S&P 500 (SPX) Up or Down on July 13?

Platform comparison

Market context

The market resolves on whether the S&P 500 closes higher on Monday, 13 July 2026, than its previous trading day close, with the index currently trading near 7,550.60 after resuming an uptrend following a spring correction [2]. The crowd-implied probability of just 1% for an "Up" move suggests traders expect a daily decline or flat close, a sentiment that contradicts the broader technical picture where the index remains above both its 50-day and 200-day simple moving averages [2].

Historically, such extreme divergence between a bullish long-term trend and a bearish daily probability is rare unless specific short-term technicals dominate. The index has recently approached a key support level where profit-taking has intensified, and the MACD has entered a corrective phase while the RSI retreated to neutral, easing overbought conditions [2]. In comparable cases where the RSI neutralises after a strong rally, daily volatility often increases, but the persistence of the price above the $7,000–$7,200 support zone typically maintains the underlying bullish bias, making a 1% "Up" probability an outlier against the established trend [2].

Traders should monitor intraday volume and any unexpected macroeconomic announcements scheduled for the US session, as the corrective phase in the MACD indicates sensitivity to short-term profit-taking rather than a trend reversal [2]. The primary catalyst remains the index's ability to hold above the identified support level; a breach below $7,200 would invalidate the long-term bullish structure, whereas a sustained hold reinforces the likelihood of the uptrend continuing despite recent profit-taking pressure [2].

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

Can I bet on individual matches?

Yes, Polymarket lists every major Premier League / Champions League / World Cup match as its own market. Liquidity varies — top matches like El Clásico or a semi-final often have six-figure pools, lower-league games closer to three-figure.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

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.
