SpaceX shares rose around 4% Thursday after Elon Musk said it would be an honor to bring former Nvidia CEO Jensen Huang aboard, intensifying speculation about Huang’s next move after he resigned immediately as Nvidia’s president, CEO and board member following 33 years at the chipmaker. Nvidia appointed Chief Financial Officer Colette Kress interim CEO while its board searches for a permanent successor. President Donald Trump separately endorsed former Apple CEO Tim Cook as his preferred replacement, although the board—not the president—has formal authority and there is no indication Cook, Huang or Musk have agreed to any arrangement. SpaceX has worked with Nvidia to source chips for planned orbital data centers, and Huang has praised the Terafab semiconductor manufacturing project involving SpaceX and Tesla. Kalshi trading assigned Cook a 10% chance of becoming Nvidia CEO, versus 42% for Ian Buck and 27% for Kress, while an earlier Action Network analysis put Buck at 35.5%, Kress at 25.5%, Arm CEO René Haas at 9.1% and AMD CEO Lisa Su at 2.4%. Wall Street analysts cut Nvidia price targets over succession, talent, supply-chain and customer-relationship concerns. Huang’s departure followed reports of extramarital relationships, including one involving a woman suspected of links to Chinese intelligence; Nvidia said it had no reason to believe company secrets or U.S. national security were compromised. His China-market advocacy and the broader allegations could continue to draw scrutiny from U.S. authorities and lawmakers, while Musk could face congressional attention over SpaceX’s government contracts and critical military and communications infrastructure role.
