Meta’s stock climbed after Instagram engagement increased and overall optimism around its AI strategy strengthened. Investors drove the rise to the strongest weekly gain noted since early 2024. The social media giant also unveiled plans to spend $50 billion to enlarge its Louisiana data centre for AI work, targeting increased capacity, strengthening 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, sparking caution among analysts.
