Meta Platforms shares surged Friday, trading at $667.81, up $36.33, or 5.75 percent, extending a rally that has pushed the stock up roughly 15 percent over the past week. According to Bank of America analyst Justin Post, an internal Meta memo suggests the company could expand computing capacity more efficiently than Wall Street had modeled. Post reiterated a Buy rating with an $835 price target, noting Meta's projected capital spending of roughly $145 billion implies construction costs near $22 billion per gigawatt, below Bank of America's earlier estimate of approximately $45 billion per gigawatt. Meta expects to deploy approximately 6.5 gigawatts of AI compute capacity during 2026. Chief Executive Mark Zuckerberg confirmed at the annual shareholder meeting that launching a dedicated AI cloud business is "definitely on the table," an initiative internally referred to as Meta Compute. On July 9, Meta unveiled Muse Spark 1.1, described as its most advanced AI model to date, targeting the agentic and coding software market. Meta is also incorporating its Muse Image model into its Advantage+ advertising platform.
