More on settlement and schedules
Three independent weekly lanes expire Monday, Wednesday and Friday at 16:00 New York time. Each lane has three strikes: a middle level and two wings currently 75 index points away.
The Pyth Equity.Index.US500/USD cash-index feed determines the result from its final 90-second observation. The outcome book can remain open outside the index trading session; a flat reference chart during that time is not a live tradable price.
Insufficient observations can lead to a 0.5 resolution under the listed rules. Read the exact terms before trading.
About S&P 500 outcomes
The S&P 500 is an index of large US companies. Skew's US500 family lets eligible traders consider listed outcomes about an index-related price at a stated expiry. The reference chart on this page uses Skew's US500 price feed, which should not be read as a tradable share or an outcome-share price. Each available contract specifies a strike, expiry, observation method, and settlement terms. An outcome share is a claim on that contract's result; it does not represent ownership of the index or its companies. Its Yes or No price is separate from the reference quote shown here. The source can have real session gaps, which the chart preserves. Check the current contract, its observation source, and its risks in Skew before deciding whether the condition matches your view.

Frequently asked questions
What can I trade in the S&P 500 market on Skew?
Skew lists outcome contracts about S&P 500-related prices. Each contract has a specific condition, strike, and expiry. An outcome share is not ownership of the underlying asset or index.
Is the S&P 500 reference price the price of an outcome share?
No. The reference chart shows Skew US500 reference feed (Pyth cash-index series). A Yes or No share has its own price in the Skew app for a particular listed condition.
How does a S&P 500 outcome settle?
The exact listed contract's rules determine the price source, observation window, boundary treatment, and any exceptional settlement. Read those rules before trading; an earlier touch of a strike may not decide an expiry-based outcome.
What can I lose on a fully paid outcome share?
A losing share can lose its entire purchase cost and applicable trading costs. In ordinary binary settlement, a winning share redeems for 1 USDC and a losing share for 0 USDC; special or void rules can differ.
Can I exit before the outcome expires?
You may be able to sell before expiry when a matching order and sufficient liquidity are available. An early exit price or execution is not guaranteed.
