ATM implied volatility by expiry for GOOGL. Points are evenly spaced rather than to time scale, and each point’s full reading appears above the chart when you hover or tap it.

ATM IV missing for some expiries

At-the-money IV needs two-sided bid and ask quotes at the strike nearest the last price. The 18 Dec expiry had none at this snapshot, so no figure is shown for it.

Among expiries a week or more away, at-the-money IV runs from 38.7% at 6 Nov to 32.1% at 4 Dec. The curve slopes down: nearer expiries carry more annualised volatility than later ones.

Put wall, call wall and max pain

Where open interest and gamma exposure concentrate for the next two monthly expiries.

GOOGL gamma and open-interest put walls, call walls and max pain by expiry
Expiry	Gamma put wall	Open-interest put wall	Gamma call wall	Open-interest call wall	Max pain
20 Nov 2026Monthly	Gamma put wall$2903.0% above spot	Open-interest put wall$2903.0% above spot	Gamma call wall$35526.1% above spot	Open-interest call wall$37031.4% above spot	Max pain$32515.5% above spot
The gamma put wall at $290 and open-interest put wall at $290 sit above the last price, so those puts are in the money.
18 Dec 2026Next monthlyClosest to 60 days	Gamma put wall$2800.5% below spot	Open-interest put wall$3006.6% above spot	Gamma call wall$31010.1% above spot	Open-interest call wall$3006.6% above spot	Max pain$3006.6% above spot
The open-interest put and call walls coincide at $300 (6.6% above spot), where open interest is largest on both sides. The put wall sits above the last price, so those puts are in the money.

For the 20 Nov expiry, gamma and open interest agree on the $290 put wall. On calls, open interest places the wall further from the last price than gamma does.
