Meta’s stock rose after Instagram engagement picked up and broad optimism around its AI strategy strengthened. Investors drove the rise to the strongest weekly gain observed since early 2024. The social media giant also revealed plans to spend $50 billion to enlarge its Louisiana data centre for AI work, seeking increased capacity, strengthening its compute capabilities. Yet still J.P. Morgan alerted on Tuesday that such large AI costs could potentially threaten Meta’s financial strength despite this week’s stock gains, raising caution among analysts.
