No. 5 Mark Zuckerberg’s fortune ($207.5 billion) plummeted $21.9 billion as Meta’s stock plunged, adding to further declines for Bezos and former Microsoft CEO Steve Ballmer, who dropped from No. 13 to No. 15 as his net worth dropped $5.8 billion to $128.6 billion. What To Watch ForApple and Nvidia are the last of the “Magnificent Seven” to post earnings this cycle, after Tesla reported last week. Apple will report after market close on Thursday, while Nvidia is expected to report on May 20. Key BackgroundAlphabet has emerged as a favorite in the accelerating AI market, while its peers, Meta and Microsoft, have fallen behind. Microsoft announced earlier this week an end to an exclusive partnership and revenue-sharing agreement with OpenAI, which will now be able to license its models and products to any third party and on any cloud, including those offered by Google and Amazon. The software giant also launched its first-ever employee buyout program earlier this month, impacting roughly 7% of Microsoft’s U.S. workforce, as it ramps up spending on AI infrastructure. Meta, a powerhouse stock in recent years, has shown vulnerability as its metaverse and AI model were reportedly delayed. The company also faced a pair of landmark court rulings in March, which found Meta and Google liable for addictive design features on their platforms and another that found Meta enabled child exploitation. Through its latest quarter, Meta reported a 5% quarterly drop in active users, citing “internet disruptions in Iran.”Further ReadingForbesOpenAI And Microsoft End Exclusive Partnership And Revenue SharingBy Alicia Park
