The same names show up in every story here: OpenAI, Anthropic, NVIDIA, Google. Here's the map: who builds artificial intelligence, who gives it power and a roof, and who in this story actually holds the keys.
The three in the window and the three behind it
The first layer is the one you know. The companies that make the models themselves, the program that answers you when you write to it.
OpenAI made ChatGPT. Anthropic makes Claude and was founded by people who left OpenAI. Google has its own unit, DeepMind, which makes Gemini. Meta, the owner of Facebook and Instagram, makes a model called Llama. There's also Elon Musk's xAI with the model Grok. And there are two Chinese companies that carry more and more weight: DeepSeek and Alibaba, whose models are called Qwen.
There's a split here worth knowing, because it keeps repeating. Some keep their models closed: you can't take them, you can only use them at their place, for money, like going to the office. Others release them open: you download the files and run them at home, free, like a standard contract that's published and anyone can adapt. OpenAI, Anthropic and Google are in the first camp. Meta, DeepSeek and Alibaba in the second. There's no nobility in it. The open model is how the weaker player gathers a crowd, while the stronger one sells access.
And now comes the part usually left unsaid: none of these companies own their machines.
Training a model like this takes thousands of specialized servers, running for months, around the clock. Power on the scale of a small city. None of these model-builders have that. They rent it.
They rent it from three. Amazon, Microsoft and Google. These are the world's three landlords. Picture the world's entire demand for computing power as a housing market: two out of every three tenants live with these three. The remaining third is split among everyone else, combined.
This is where it gets interesting, because the landlord is more than a landlord. Microsoft doesn't just give OpenAI servers. Microsoft owns part of OpenAI. After the restructuring in the fall of 2025, it holds around a quarter of the company. In other words, the landlord is also a co-owner of the tenant who pays it rent.
With Anthropic it's even more tangled, because it has two investors, and they hate each other. Amazon poured into Anthropic the kind of money a government sets aside for a highway. Anthropic, in turn, committed to paying over a hundred billion dollars back to Amazon over the next ten years, as payment for servers. Money goes in, money comes out the same way. At the same time, Google also put billions into Anthropic, meaning it funds the direct competitor of its own Gemini, and in return got Anthropic as a customer for its chips. Two rivals, holding the same third party, which then pays rent to both.
That leaves the third layer, the bottom one, and it's the narrowest of all. The chips. The silicon that actually does the math. Here almost everything runs through one company, NVIDIA. Nine out of every ten dollars NVIDIA earns come from chips for these servers. It isn't one of the players in this market. It is the market.
And since you already know how these people behave, you won't be surprised: NVIDIA announced it plans to put up to a hundred billion dollars into OpenAI, tied to OpenAI deploying its systems. In other words, the seller lends the buyer money so the buyer can buy the seller's goods.
The Chinese play by different rules, because US bans don't let them buy NVIDIA's strongest chips. So DeepSeek rewrote its models to run on Chinese chips, and Alibaba chose a different move: it released its models open and free, and more people now download them than any other model in the world - including Meta. They were banned from buying the machine. They gave the program away for free.
What will last
Look at the circle again, slowly. NVIDIA funds OpenAI so OpenAI can buy NVIDIA chips. Amazon funds Anthropic, and Anthropic pays the money back to Amazon as rent. Google funds its own model's competitor and sells it chips. The same money circles among the same dozen or so companies, and every time it passes through someone's till, it counts as a new success.
I'm not saying this is a cartel. I'm saying it's a very small club, where everyone is at once investor, supplier, customer and competitor of everyone else. If you saw something like this in an industry back home, you'd call an auditor.
Here's the practical part, the reason I'm writing this at all. When you choose between ChatGPT, Claude and Gemini, it feels like you're choosing between three companies. You're not. You're choosing between three storefronts. Behind them is the same warehouse, the same three landlords, and the same chip supplier. If tomorrow the landlord raises the rent, or the chip supplier falls behind, it won't hit one product. The whole pyramid will crack, and you'll feel it through your phone, no matter which icon you tap.
So the next time you read a story about some breakthrough, don't look at the storefront's name. Ask who's paying its power bill. The answer is almost always the same, and almost always matters more than the story itself.
