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