AI spending isn't spreading out—it's piling up at the top.

10% of US software companies now pay for GPU infrastructure, up from under 4% two years ago. Most of that jump? Model inference—the computing power to actually run AI and handle requests.

But here's the thing: the top 10% of spenders control 99.5% of model-serving dollars and 99% of specialized AI cloud spend. They also own 95%+ of OpenAI, Anthropic, and general cloud budgets.

More companies are dipping their toes in AI. But the real money? Still locked in with the heavyweights.

This matters for cloud providers, chip makers, and anyone betting on broad AI monetization. Adoption is widening, but revenue concentration hasn't budged.
