Billionaire Ken Griffin Bets Big on Meta Platforms
Rich guy Ken Griffin, who runs a big investment company, suddenly bought a lot of shares in Meta (the company that owns Facebook and Instagram).
He did this because Meta is doing really well with artificial intelligence, which helps them show better ads and recommend cool stuff on Instagram.
Other smart investors are also betting on AI, so Griffin is joining them.
He started his company in college with just $4.6 million and now manages over $65 billion.
His big bet on Meta shows he thinks the company will do great things with AI.
Ken Griffin, Citadel founder, significantly increased Meta Platforms stake by 12,693% in Q3 2025
Meta's AI efforts drive record sales of $51.2 billion, up 26% from previous year
Griffin's tech portfolio shift focuses on AI, increasing stakes in Microsoft, Apple, Alphabet, Tesla, and Nvidia
Citadel's current Meta holding worth roughly $1.44 billion, making it one of Griffin's largest tech investments
