What the positioning says

●Call wall at $860 (410 contracts), 9% above spot — the upside strike the crowd is already parked on; often acts as near-term resistance.
●Put wall at $500 (447 contracts), 37% below spot — the hedge floor; often acts as support.
●30-day ATM implied volatility is 70% — the market prices very large moves; option premium is expensive.
