1004 GMT - Meta is targeting untapped consumers as it seeks to monetize AI, diverging from competitors looking to sell AI products to businesses, Bernstein analysts write. "While everyone else zigs to focus on the easier-to monetize enterprise segment, Meta is zagging towards the greenfield consumer opportunity." However, detail on Meta's plans remains light, as the question of "how the business model works remain unanswerable," the analysts say. If Meta can work out a way to monetize AI usage among its huge customer base, the benefits would be enormous, the analysts say, "but it remains an expensive 'if'." Meta shares fall 8.7% premarket. The stock is on track to extend its longest losing run in history.
