Meta’s stock climbed after Instagram engagement picked up and broad optimism around its AI strategy deepened. Investors drove the rise to the most notable weekly gain observed since early 2024. The social media giant also unveiled plans to spend $50 billion to expand its Louisiana data centre for AI work, targeting increased capacity, bolstering its compute capabilities. Yet nevertheless J.P. Morgan warned on Tuesday that such large AI costs could later threaten Meta’s financial strength despite this week’s stock gains, sparking caution among analysts.
