What is AMZN gamma exposure today?
AMZN net gamma exposure is $21M for every 1% move, which is a positive gamma regime, measured from the option chain at the close on 2026-07-23. Gross gamma across the same contracts is $544M, so the net figure is about 4% of the total in size — the rest cancels out between calls and puts. The estimated gamma flip level, where the regime would switch sign, is $231.32, which is -0.34% from the last traded price of $232.11. The single largest gamma wall sits at $230.00, carrying 9.9% of all the gamma in the chain. In plain terms: the dealers on the other side of these options are estimated to be net long gamma, so their hedging sells strength and buys weakness, which mechanically calms the tape. This is an estimate of positioning built from public open interest, not a look inside anyone's book.
How to read this AMZN configuration
The sign first. Net GEX is $21M, so this is a positive gamma reading. Positive gamma is the quiet regime. Every rally leaves dealers with more share exposure than their hedge requires, so they sell; every dip leaves them with too little, so they buy. That flow leans against whatever the market just did, and the practical effect is that ranges tend to be narrower and moves tend to stall rather than extend.
Then the distance to the flip. The flip level is $231.32, 0.34% below the last price. That is close. When price is hovering right at the flip, the regime is unstable: a single ordinary session can push the whole chain from calm to jumpy or back. This is the configuration where GEX changes fastest and where a stale snapshot misleads you most.
Then the concentration. The biggest strike, $230.00, holds 9.9% of the chain's gamma — enough to be worth marking on a chart, not enough to dominate. Expect the level to matter a little, and only in the short run.
What this number is not. Public GEX is a model on top of a guess. It uses end-of-day open interest, assumes every call is long for the dealer and every put is short, and prices gamma with a simplified Black-Scholes approximation. Real market-maker books are hedged across futures, other expirations and other products, and nobody outside the firm sees them. Read this as a description of the volatility environment, not as advice, and never as a reason to buy or sell.
Net gamma by strike
■ positive gamma (hedging leans against the move) ■ negative gamma (hedging leans with the move) — strikes near the last price. Bar height is the estimated dollar hedging requirement per 1% move at that strike.

Gamma walls
The strikes carrying the most gamma. "Share" is that strike's slice of all the gamma in the chain, so a handful of rows adding up to a large share means the hedging is concentrated in a narrow band of prices.
| Strike | Net GEX per 1% | Share of gamma | From last price |
|---|---|---|---|
| $230.00 | -$54M | 9.9% | -0.91% |

Gamma by expiration
Which expirations hold the exposure. Short-dated contracts usually carry most of the gamma, which is why the whole picture can reset the day after a big expiry.

The expiry view of the same AMZN chain
Gamma exposure is about what happens every day as price moves. Max pain is about one moment: the settlement price that would pay option holders the least. They come from the same open interest and often point at different levels. See AMZN max pain for that side, and max pain vs gamma exposure for what it means when the two disagree.

What is gamma exposure builds the idea from one option and one hedge, with the arithmetic written out, then explains why every public GEX number is an estimate. What is max pain does the same for the expiry-payout calculation.

Gamma exposure for other tickers
Gamma exposure is computed nightly from end-of-day open interest and closing quotes using a Black-Scholes approximation with zero rate and zero dividend, matching the convention most public GEX trackers use (how we compute it). A derived estimate, not raw market data and not a live quote. Educational only: not investment advice, not a recommendation, not a price forecast.
