deep-OTM puts vs calls

What the positioning says

●Call wall at $900 (3k contracts), 137% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $240 (4k contracts), 37% below spot — the hedge floor; often acts as support.
●30-day ATM implied volatility is 68% — the market prices very large moves; option premium is expensive.

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.
