Meta’s stock advanced after Instagram engagement increased and broad optimism around its AI strategy solidified. Investors pushed the rise to the most notable weekly gain observed since early 2024. The social media giant also disclosed plans to spend $50 billion to expand its Louisiana data centre for AI work, seeking 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.
