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