About SPDR S&P 500 ETF Options

SPY tracks the S&P 500 index, representing the 500 largest US companies. The most liquid options market in the world with daily (0DTE) expirations available.

SPY options are the gold standard for options traders — deepest liquidity, tightest spreads, and available in daily expirations for 0DTE strategies. Perfect for index hedging and income strategies.

How to Read the SPY Option Chain

Each row above is one strike price. Calls (right to buy SPY) sit on the left; puts (right to sell) sit on the right. For both sides you see the bid, ask, last traded price, volume, implied volatility (IV%) and delta (Δ). The highlighted row is the at-the-money strike — the one closest to the current SPY price of $713.72.

Bid/ask is what buyers are willing to pay and what sellers want; the midpoint is a fair estimate of the option's value. Last is the most recent trade. IV% is the market's implied forecast of SPY's future price movement — higher IV means pricier premiums. Delta roughly equals how much the option price moves per $1 change in SPY.
