Meta’s stock climbed after Instagram engagement picked up and wide optimism around its AI strategy solidified. Investors propelled the rise to the best weekly gain recorded since early 2024. The social media giant also revealed plans to spend $50 billion to expand its Louisiana data centre for AI work, aiming for increased capacity, strengthening its compute capabilities. Yet still J.P. Morgan alerted on Tuesday that such large AI costs could eventually threaten Meta’s financial strength despite this week’s stock gains, triggering caution among analysts.
