Net gamma exposure by strike ($M per 1% move) · estimated from the RIVN options chain (Polygon).
As of the latest session, RIVN is trading at $17.50 (+7.16% on the day). Net dealer gamma is positive, with the zero-gamma flip near 16.69.

RIVN is in positive gamma. Dealers are net long gamma — they sell strength and buy weakness, which compresses volatility and pulls price toward the big strikes. Expect a grindy, mean-reverting tape that wants to pin near 16. The edge is fading the extremes of the 16–18 band — until 16.69 gives way to the downside.

RIVN is currently in positive gamma, with the zero-gamma flip near 16.69. Positive gamma means dealers dampen moves — a calmer, mean-reverting, pin-toward-the-strikes tape.
RIVN's zero-gamma flip is around 16.69 — the price where net dealer gamma crosses zero. Above it the tape tends to be positive-gamma (suppressed, range-bound); below it, negative-gamma (amplified, trending). Reclaiming or losing the flip is the single most important level on the map.
RIVN's call wall (18) is a magnet and resistance; the put wall (16) is support in positive gamma but a through-level once price is below the flip.
RIVN's max pain is 16 — the strike where the most options expire worthless. In a positive-gamma tape, price often gets drawn toward max pain into expiration.
Gamma exposure is a map of where option dealers are forced to hedge. Positive GEX = dealers sell strength / buy weakness (suppresses volatility, pins price). Negative GEX = dealers chase the move (amplifies volatility, trends). It tells you the character of the tape, not the direction. Full GEX guide →
