U.S. stock futures popped on Wednesday ahead of key U.S.-China trade discussions and the Fed's policy decision—here are the top premarket movers:

1. Walt Disney (NYSE:DIS): +6.2%

Disney beat Q2 revenue and EPS estimates, driven by stronger-than-expected Disney+ subscriber growth and higher spend at its U.S. theme parks. Investor focus now turns to subscriber retention and park attendance trends in upcoming reports.

2. Uber (NYSE:UBER): -3.5%

Uber disappointed with softer-than-forecast gross bookings and a slowdown in its rideshare segment—fanning concerns over consumer spending in a murky economic environment. The launch pace of its Price Lock Pass will be under scrutiny in Q2.

3. Advanced Micro Devices (NASDAQ:AMD): +1.5%

AMD lifted its Q2 revenue outlook, citing a rush to secure chip orders before new U.S. tariffs hit. Investors will watch whether the guidance sticks once those levies take effect.

4. Marvell (NASDAQ:MRVL): -7%

Marvell postponed its June 10 Investor Day to 2026, blaming macro uncertainty—raising questions about near-term visibility into its 5G and data-center growth drivers.

5. Super Micro Computer (NASDAQ:SMCI): -5.3%

SMCI's Q3 beat on earnings but missed on revenue, and its trimmed full-year outlook weighed heavily on the stock, highlighting the delicate balance between hyperscaler demand and inventory cycles.

6. Novo Nordisk (NYSE:NVO): +5.5%

Novo Nordisk cut its sales forecasts for Wegovy for the first time in four years but still anticipates a U.S. recovery. Watch for updates on prescription trends and pricing dynamics in its next earnings call.

7. Boeing (NYSE:BA): +0.3%

Boeing underperformed the broader market after the Financial Times reported potential EU tariffs on its aircraft—part of a brewing transatlantic trade standoff if talks with Washington falter.
