For the past two years, the generative artificial intelligence boom has largely been defined by a single market. Hyperscalers have dominated the market with massive capital spending. According to CreditSights, the five largest U.S. hyperscalers — Amazon Web Services Inc., Microsoft Corp., Google LLC, Meta Platforms Inc. and Oracle Corp. — are on pace to spend roughly $700 billion to $800 billion in capital expenditures this year, with about three-quarters of that spending tied directly to AI infrastructure.
