Nasdaq futures plunged on Tuesday as a rout in memory chipmakers spurred doubts about the AI trade, piling pressure on stocks more broadly even as US-Iran talks showed progress.

Contracts on the tech-heavy Nasdaq 100 dived 2.8%, while those on the S&P 500 sank 1.4%.

Dow Jones Industrial Average futures, which include fewer tech names, slid 0.5%.

The Nasdaq is set for another hammering, after Monday saw Big Tech players take a hit as SpaceX notched its third day of losses in a row.

Shares in Elon Musk's space company were down another 5% before the bell, on track to push below $2 trillion in market value. Yahoo Finance reports.
