Resolution rules
If Astera Labs is announced to be or is officially added to S&P 500 during October 1, 2026 to December 31, 2026, then the market resolves to Yes.
How to read these odds
Each price runs from $0 to $1 and can be read as the probability the market assigns to an outcome: $0.62 means roughly 62%. Prices move with every trade, so they are a crowd estimate, not a guarantee. Before trading, check the resolution rules above, the volume and the liquidity, and only risk money you can afford to lose.
