Meta CEO Mark Zuckerberg plans to ramp up his company's spending on artificial intelligence in 2026. Zuckerberg was referring to Meta's ambitious data center buildouts intended to anchor both current and future AI projects. Zuckerberg said 2026 will be a major year for AI, with Meta's investments geared towards supporting his mission for "building personal super intelligence." Asked on the call why Meta needs to develop its own powerhouse AI foundation model, Zuckerberg said it's important because Meta is a "deep technology company." In the meantime, online advertising still accounts for the overwhelming majority of Meta's revenue.
