Pronóstico: S&P 500 (SPX) Up or Down on July 8?

Platform comparison

Market context

The market resolves whether the S&P 500 closes higher on Wednesday, 8 July 2026, than on the most recent prior trading day, with the crowd assigning only a 16% chance of an upward move. This low probability reflects the index’s recent weakness: over the past five days, the SPX has fallen 1.53%, while the one-month and three-month changes sit at -6.27% and -6.53% respectively[2]. Historically, such short-term declines following multi-week losses often precede further downside unless a clear catalyst emerges, as seen in mid-June when the index dropped from 7,541 to 7,350 over three days before continuing lower[4].

Traders should watch for any surprise shifts in US economic data, particularly service-sector activity or payroll trends, which recently showed expansion at a slower pace amid easing cost pressures[1]. Strength in chipmakers, AI infrastructure stocks, and megacap technology companies lifted the market on Monday, but that momentum has not held, with the index now down 0.83% on the day and trading near 7,441[6][9]. A trader must monitor whether the service sector’s slowdown accelerates or if tech stocks regain leadership, as these dependencies will determine whether the index breaks its recent downward trajectory or extends it.

FAQ

When do sports markets resolve?

Typically within hours of the official final whistle. Polymarket uses UMA Optimistic Oracle with source URLs pointing at official league data feeds — e.g. the Premier League for EPL markets, UEFA for Champions League, FIFA for World Cup.

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.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

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.
