Meta’s stock advanced after Instagram engagement grew and broad optimism around its AI strategy deepened. Investors pushed the rise to the best 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 however J.P. Morgan warned on Tuesday that such large AI costs could eventually threaten Meta’s financial strength despite this week’s stock gains, sparking caution among analysts.
