On this week’s “Marketplace Tech Bytes: Week in Review,” we take a look at Nvidia's changing investment relationship with OpenAI.

Plus, a stormy start for the new U.S. version of TikTok.

But first, SpaceX, one of the world’s largest rocket companies, announced this week that it’s buying xAI, a two-and-half-year-old artificial intelligence startup. Both companies are controlled by Elon Musk.

The new company is reportedly valued at $1.25 trillion. It means the chatbot Grok, the satellite internet company Starlink, and the social media firm X are all going to co-exist under the same rocket hangar.

Marketplace’s Stephanie Hughes spoke with Paresh Dave, senior writer at Wired, about what adding these companies together equals.
