S&P 500 (SPX) Up or Down on June 24?

Platform comparison

Market context

The S&P 500 closes today at 7,352.56, down 0.18% from the prior session, meaning the June 24 settlement will resolve "Down" as the index fails to beat the most recent prior trading day’s close[1]. This outcome aligns with the crowd-implied 0% probability for "Up", reflecting a market that has slipped 1.44% over the last day amid broader equity weakness[4].

Historically, days following a 1%+ drop like today’s often see continued pressure, as seen in June 22 when the index fell from 7,500.44 to 7,366.51, setting a pattern of consecutive declines that rarely reverse within a single session[2][6]. Such momentum-driven drops, especially when paired with a 52-week high of 7,620.90 already tested in early June, suggest limited immediate upside without a fresh catalyst[5].

Traders should monitor the Federal Reserve’s upcoming policy statement and the Q2 GDP preliminary release, both scheduled this week, as these could shift risk sentiment sharply[6]. Recent commentary from the WSJ notes that war premium evaporations, such as gold tumbling to $3,972, signal reduced defensive demand and may amplify equity volatility[1]. On Polymarket, conditional tokens settle in USDC on Polygon, so liquidity and slippage remain key for position entry before the 20:00 UTC deadline.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

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.
