Meta’s stock climbed after Instagram engagement increased and broad optimism around its AI strategy strengthened. Investors pushed the rise to the strongest weekly gain observed since early 2024. The social media giant also revealed 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 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.
