Nasdaq, S&P 500, Dow Futures Crack On Tech, SpaceX Selloff: Why SPCX, TSLA, INFQ, MU, HOOD, ADTX Are In Focus

• The Nasdaq is poised for its worst opening in weeks as renewed selling in AI and technology stocks spreads from Wall Street to Asian markets on Tuesday. 
• Crude oil eased on progress toward a potential peace agreement between the U.S. and Iran. 
• Investors await fresh economic data, Micron earnings and developments around the U.S.-Iran negotiations this week. 

U.S. stock futures fell sharply early Tuesday morning as a steep selloff in megacap technology shares and a multi-day plunge in newly public SpaceX weighed on investor sentiment, overshadowing optimism from a preliminary 60-day U.S.-Iran peace roadmap that helped cool crude oil prices. 

The tech rout expanded to Asian markets on Tuesday as well, with South Korea’s Kospi index triggering a circuit breaker amid reports that semiconductor giant SK Hynix is slowing its AI memory expansion.

Meanwhile, on Monday, President Donald Trump signed two executive orders on quantum computing, and the Senate passed a major housing affordability bill that bars the Federal Reserve from issuing a central bank digital currency (CBDC) until 2030. 

As of 4:00 a.m. ET, Nasdaq futures were down 2.7%, S&P 500futures declined 1.5%, Dow futures fell 0.7%, and Russell 2000 futures declined 1.7%.

On Stocktwits, retail sentiment for the SPDR S&P 500 ETF (SPY), an exchange-traded fund that tracks the S&P 500 Index, has flipped to ‘bearish’ from ‘bullish’ a day ago, and the Invesco QQQ Trust (QQQ) ETF, which tracks the Nasdaq-100 Index, has declined to ‘neutral’ from ‘bullish’.
