What the positioning says

●Call wall at $55 (16k contracts), 21% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $42.5 (9k contracts), 6% below spot — the hedge floor; often acts as support.
●30-day ATM implied volatility is 22% — calm pricing; option premium is cheap.

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 2026-09-18. 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.
