Zoom's quiet $51 million investment in Anthropic just became the video conferencing giant's best-kept secret. Baird analysts dropped a bombshell Monday, estimating the 2023 stake could now be worth between $2 billion and $4 billion—a staggering 78x return—as the AI startup behind Claude rockets to a $350 billion valuation. The revelation sent Zoom shares soaring 11% and suddenly repositioned the pandemic darling as an unexpected player in the AI investment sweepstakes.
Zoom just pulled off one of tech's quietest wins. The company that became synonymous with pandemic-era video calls has been sitting on an Anthropic investment that could eclipse its entire quarterly revenue—and almost nobody noticed until now.
Baird analysts revealed Monday that Zoom's May 2023 investment in the AI startup, tucked away in an SEC filing as $51 million in "strategic investments," has ballooned to an estimated $2 billion to $4 billion. That's based on Anthropic's current $350 billion valuation, which places the Claude AI maker among the most valuable private companies on the planet.
"While we (and the market) have been primarily focused on ZM's ability to gradually reaccelerate revenue growth and capture AI opportunities, the quieter, hidden gem might be its $51 million investment in Anthropic in 2023," Baird's analysts wrote in a note that sent Zoom shares up 11% by market close.
The timing couldn't be better for Zoom. After riding the pandemic wave to unprecedented heights, the company's struggled to maintain momentum as workers trickled back to offices and competitors like Microsoft Teams and Google Meet ate into its market share. Revenue growth has decelerated, and the stock remains far below its 2020 peaks despite recent AI-powered product updates.
But Anthropic changes the math entirely. When the partnership was announced in May 2023, it looked like a typical enterprise AI integration—Zoom would embed Anthropic's technology, Zoom Ventures would take a stake. The companies didn't disclose investment terms, and the market largely shrugged.
