Meta’s stock advanced after Instagram engagement grew and overall 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 enlarge its Louisiana data centre for AI work, seeking increased capacity, supporting its compute capabilities. Yet however J.P. Morgan alerted on Tuesday that such large AI costs could later threaten Meta’s financial strength despite this week’s stock gains, sparking caution among analysts.
