Meta’s stock rose after Instagram engagement picked up and wide optimism around its AI strategy solidified. 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, aiming for increased capacity, bolstering its compute capabilities. Yet however J.P. Morgan alerted on Tuesday that such large AI costs could eventually threaten Meta’s financial strength despite this week’s stock gains, raising caution among analysts.
