The negotiations started as just one billionaire tech founder talking to another. Meta Platforms CEO Mark Zuckerberg approached Scale AI CEO Alexandr Wang in mid-April about a potentially industry-shaking deal.

Meta is making a $14.3 billion investment in artificial intelligence company Scale and recruiting its CEO Alexandr Wang to join a team developing “superintelligence” at the tech giant.

Google is reportedly cutting ties with Scale AI after Meta acquired a 49% stake in the data-labeling startup, according to Benzinga. Google was previously Scale AI’s largest customer, and it is reportedly planning to end its relationship with the company.

Meta’s Mark Zuckerberg is bringing in Scale AI CEO Alexandr Wang to help the social media company better execute on its AI ambitions.

Meta invests $14.3B in Scale AI to fuel a new superintelligence lab—gaining infrastructure and leadership, but raising doubts about Scale’s future.

As part of the deal, Scale AI’s CEO will take a top position inside Meta, leading a new “superintelligence” lab, according to the report.

It’s easily the most expensive hire of all time, dwarfing the billions that Google spent to rehire Noam Shazeer and his core team from Character.AI (a deal Zuckerberg passed on). “Opportunities of this magnitude often come at a cost,” Wang wrote in his note to employees this week. “In this instance, that cost is my departure.”
