Market context
The S&P 500 index, tracked by the SPY exchange-traded fund, will close on 13 July 2026 either above or below a specified price level. This settlement hinges on the closing price recorded at market close on that date, with no adjustment for after-hours trading. The 0% crowd probability suggests traders have assigned negligible likelihood to the affirmative outcome, indicating either an exceptionally high strike price or a consensus view that the index will remain below the threshold.
Historical precedent shows that S&P 500 price targets assigned near-zero probability typically reflect strikes positioned well above prevailing market levels or technical resistance. During comparable periods of market uncertainty—such as the 2020 pandemic shock or 2022 rate-hiking cycle—similar extreme probabilities emerged when strike prices were set three to five standard deviations above the then-current index level. The current reading suggests the market has priced in either a substantial rally requirement or structural headwinds expected to persist through mid-July 2026.
Traders monitoring this contract should track Federal Reserve communications, corporate earnings announcements, and macroeconomic data releases scheduled between now and settlement. Inflation reports, employment figures, and any unexpected policy shifts could materially alter equity valuations. Additionally, geopolitical developments and credit-market stress indicators warrant attention, as these have historically driven sharp index movements. The settlement date falls during the second-quarter earnings season, when guidance revisions and forward outlooks often trigger significant repricing across the broader market.
Methodology
Political prediction markets differ structurally from sports betting: thinner liquidity, longer settlement windows, higher sensitivity to single news events. This page shows the live Polymarket quote for S&P 500 (SPY) closes above … on July 13? plus platform attributes for the three reference venues, so you can see at a glance where the deepest market for this question sits.
Resolution & payout
For political markets the resolution source is decisive. Polymarket defines a concrete source per contract (e.g. AP, Reuters, official electoral commission) and uses the UMA Optimistic Oracle as the on-chain dispute mechanism. With a clearly defined outcome the USDC payout lands within minutes of the final confirmation.
FAQ
- How accurate are political prediction markets?
- Historically more accurate than polls. Polymarket's Brier score on US 2024 elections was ~0.11 — better than 538 (~0.14) and every mainstream poll. Markets aggregate information with real skin in the game.
- What resolution source is used for elections?
- Polymarket defines the source per contract — usually Associated Press (AP Race Call), Reuters or the official electoral commission. The source is stated in contract details before the market opens.
- Which platform has the deepest political liquidity?
- Polymarket — by far. US 2024 presidential volume was ~$3.5B vs Kalshi (~$200M) and Betfair (~$120M). Where Polymarket is geo-blocked, brokers like Election Predictions UK route into the same order book at 0% fees.
- Are political prediction markets legal in my country?
- It varies. They sit in legal gray areas in most jurisdictions. Polymarket is geo-blocked from US/UK/EU; some broker frontends have a different geo footprint. Trade only with capital you can afford to lose, and only if you understand the legal status in your jurisdiction.
- Why do Polymarket and Kalshi differ on elections?
- Kalshi must follow CFTC compliance — strict definitions, clear resolution sources, US citizens only with KYC. Polymarket operates globally without CFTC oversight — deeper liquidity, but also higher regulatory risk.
