Meta's stock heads for best week since early 2024 as optimism builds around AI strategy

Meta's stock rose 15% this week after the company announced new AI models and tools, including Muse Image (for creating images) and Muse Spark 1.1 (for running agentic and coding workloads, which means AI systems that can plan and act independently). The optimism reflects investor confidence that Meta's large spending on AI infrastructure and data centers will eventually create profitable new business lines beyond its traditional advertising revenue.
