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