Meta’s stock climbed after Instagram engagement picked up and broad optimism around its AI strategy strengthened. Investors pushed the rise to the best weekly gain noted since early 2024. The social media giant also revealed plans to spend $50 billion to expand its Louisiana data centre for AI work, targeting increased capacity, strengthening its compute capabilities. Yet still J.P. Morgan alerted on Tuesday that such large AI costs could eventually threaten Meta’s financial strength despite this week’s stock gains, sparking caution among analysts.
