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