# US Markets Thursday May 21 2026: Nvidia $91B, Samsung Relief, FOMC Hike Language — The Triple Catalyst Open

> **Quick answer:** US equity futures are flat to slightly lower Thursday morning as markets process three major catalysts simultaneously: Nvidia's blowout Q1 report with $91B Q2 guidance, Samsung's last-minute strike deal that sent Korean shares up 6%, and FOMC minutes that solidified rate-hike language while the 30-year Treasury yield sits at a 19-year high of 5.18%. The rally that many expected from Nvidia's results is running into the wall of the bond market.

US markets Thursday May 21 2026 face one of the most complex pre-open environments of the year. Nvidia beat on every line and guided higher. Samsung resolved a potential supply-chain catastrophe. And yet S&P 500 futures are essentially flat, Nasdaq 100 futures are unchanged, and Dow futures are off about 50 points. The bond market is explaining why — and investors need to understand the tension before the bell rings.

This is not a clean "risk-on" open. It is a three-way tug-of-war, and the outcome depends heavily on which catalyst wins the narrative by midday.
