Elliott Investment Management has taken a $1 billion stake in Pinterest, signaling confidence in the company's AI-driven turnaround strategy. Pinterest CEO Bill Ready highlighted record 2025 revenue, all-time high user counts, and over 80 billion monthly searches powered by AI visual search. Alongside the investment, Pinterest announced a $1 billion accelerated share repurchase and a broader $3.5 billion buyback program, sending shares up 6% in premarket trading. The move comes despite a difficult year for Pinterest marked by disappointing earnings, 15% workforce layoffs, a declining ad business, and competition from AI chatbots. Elliott's history of activist pressure—including pushing eBay to sell StubHub and its Classifieds unit—suggests Pinterest may face heightened scrutiny and pressure for strategic changes.
