Daily Brief — Mon Oct 26, 2026

SPY opens 0.29% higher, still in net short gamma (−$2.54B), with a −$1.70B put wall at 755 — the biggest put wall in the last four briefs, seven points under spot — and a 765 call wall (+$345M) two and a half points over it. Plus 8 names with real options flow, led by $1.1M of CART calls in two prints.
Tape: risk-off but stabilizing — chain is net short gamma (−$2.54B), no flip, vol down to 20 SPY: 762.16 +0.29% pre-market, 759.97 implied Friday close Exp move: ±0.7% 0DTE — ±$5.68 (756.48–767.84), down from ±0.9% Friday Bias: 763–765 is the positive band (+$658M); 755 put wall (−$1,698M) sits just under the expected-move floor

1 · The one thing that matters today

SPY map 13:01 UTC · sweeps 13:08 UTC · pre-market

SPY (762.16) opens on a seam: 762 holds −$228M and 763 holds +$180M, and the whole upside question is whether it can hold the first positive band at 763–765. Those three strikes sum to +$658M, with the 765 call wall (+$345M) the largest. 766 flips negative again (−$177M), then 767–776 are positive and add another +$407M. The feed returns no zero-gamma flip, and the chain total is −$2,536M: −$3,485M below spot, +$949M above. Friday it was −$2,778M with +$277M above, so the overhead side has more than tripled.

The put wall dropped again, and it is huge. 755 holds −$1,698M, larger than the put wall in any of the last four briefs (−$587M, −$148M, −$258M, −$652M) and 2.5 times the next strike (750, −$671M). It sits 7.16 below spot, 1.48 under the floor of today's expected move (±0.7%, or ±$5.68 for a 756.48–767.84 range). The put wall has stepped down every day: 765 Wednesday, 764 Thursday, 760 Friday, 755 today. Between spot and that wall, 756–760 add another −$561M. Max pain is 763, 0.84 above spot, and implied vol (ATM) is 20, down from 23 Friday.

Friday closed on the wall. SPY's implied prior close, backed out of the +0.29% change, is about 759.97 — a few cents from Friday's 760 put wall (−$652M), which has been replaced by a deeper one lower. The call wall has moved the other way, 776 → 770 → 765 over three days. This feed carries only the 0DTE chain (one expiry, 246 contracts), so open interest further out is not in these numbers.
