Anthropic's Revenue Surge Meets an Iran Ceasefire Deadline: Markets Today, August 17, 2026

Anthropic's Revenue Surge Meets an Iran Ceasefire Deadline: Markets Today, August 17, 2026

Futures are mixed-to-firmer after another quiet, record-setting week for US stocks, with an Anthropic-fueled AI rally offsetting Fed and Middle East jitters. Today's session hinges on a light data slate — Empire State manufacturing and NAHB housing — set against an Iran ceasefire deadline that expires today and a retail-earnings gauntlet that starts in earnest tomorrow with Home Depot.

Market setup

Key levels (dealer gamma)

Call walls mark strikes where dealer hedging may slow rallies; put walls mark strikes where hedging flows may cushion dips. These are positioning estimates, not guarantees.

Index snapshot (last close)

Today's market calendar (ET)

Notable earnings

Already reported: Bally's Corp (BALY) posted a loss of $3.76 per share versus consensus of -$2.10, a 79% negative surprise, ahead of today's open.

Still ahead before the open: H World Group (HTHT), FUFU and InspireMD (NSPR) round out the pre-market slate.

After the close: Fabrinet (FN) ±10.4%, XP Inc (XP) ±5.3%, Yalla Group (YALA) ±9.1%, plus DocGo (DCGO) and Flexsteel (FLXS) also report.

Key themes for the day

1. Anthropic's revenue shock ignites the AI trade. Q2 revenue surged more than 14-fold year-over-year to over $11.5 billion, lifting chipmakers Sandisk and Micron in premarket trading.
2. Iran ceasefire clock runs out. The US-Iran truce expires today with Strait of Hormuz shipping traffic nearly halted and the US Strategic Petroleum Reserve below 300 million barrels for the first time since the early 1980s.
3. Yields camp out near cycle highs. The 10-year sits at 4.69% even as futures now price a roughly 67% chance the Fed holds rates in September.
4. Retail earnings gauntlet begins. Home Depot reports tomorrow, days after July retail sales fell 0.6% and consumer sentiment sank to 51.0.
5. Record highs, but the tape is pinned. Dealer gamma shows the largest SPY call wall at 780 and largest put wall at 775, both essentially at spot.

Notable options flow

What to Watch

Keep an eye on the 8:30 AM Empire State print for a read on whether elevated yields are biting into manufacturing sentiment, and watch WTI crude for any escalation headlines out of the Strait of Hormuz as the ceasefire deadline passes. Home Depot's earnings tomorrow will be the first real test of how consumers are absorbing tariff-driven price increases after last week's weak retail sales and sentiment data. Options positioning suggests the S&P 500 may stay rangebound between roughly 775 and 780 on SPY unless one of these catalysts breaks the current gamma regime.

Sign-off

That's the setup heading into the bell. Markets remain near records, but today's mix of geopolitical deadlines, elevated yields, and the start of retail earnings season means the next directional move could come from any of several directions. Stay nimble.
