What the positioning says

●Defensive positioning: 1.15 puts outstanding per call — holders are hedging rather than selling.
●Call wall at $290 (3k contracts), 13% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $220 (2k contracts), 15% below spot — the hedge floor; often acts as support.

Open interest by strike

All expiries combined. Amber lines mark the call and put walls; the dashed line is spot.

IV term structure

At-the-money implied volatility per expiry.

Volatility smile

IV by strike — expiry 2026-10-30. A steep left side = expensive downside protection.

30-day implied volatility history

Daily ATM IV (~30 DTE bucket) collected since March 2026. Rising IV into an event = the market bracing; collapsing IV after = the crush.
