In the first half of 2025, major U.S. tech companies like Microsoft, Google, Meta, and Amazon have spent over $1.55 trillion on artificial intelligence infrastructure. The spending exceeds U.S. government allocations for education and social services. Investments focus on data centers, servers, and power-intensive systems needed to run AI. Microsoft alone plans to spend over $300 billion this quarter. With 2026 plans already underway, global AI investment is expected to grow rapidly, even surpassing some national defense budgets in scale.
