Alphabet, Amazon, Microsoft, and Meta, which are the world’s biggest technology companies, are expected to spend $725 billion on artificial intelligence (AI) infrastructure in 2026. This information comes from a Bloomberg report. Most of the money will go to building large computer centres and buying special high-performance chips, like those made by the company NVIDIA.

The companies are making this big investment because they want to create the physical systems needed for new AI services. These systems help them run faster and smarter digital services for people around the world.

As a result, investors are watching these companies carefully. Many people in the financial world worry that profits from these AI services might not come soon enough to cover the huge spending.
