Behind every model there is a bill. Someone puts up the money, someone takes a cut of every payment, and someone's music, photo or article went into the training without anyone asking. Here is who profits, who pays, and who hasn't noticed yet that they're in the game.
The money comes first
According to the Stanford AI Index 2026, private AI investment in the US reached $285.9 billion in 2025. That is more than 23 times the $12.4 billion in China, though the report warns that private figures likely understate China because of its government guidance funds. Most of this money isn't buying profit today. It's buying a bet that years from now this particular company will be among the survivors.
So when you read that a startup is losing billions and still growing, don't rush to call it stupid. That's how venture capital is built: many bets, few winners, and the winner pays for all the rest. The node on venture capital walks through the math from the inside, with the names of the funds.
The rails the payments run on
The second group profits from money moving, not from the model. Stripe sits behind card payments for a huge part of the internet. Stablecoins and tokenised assets move money and securities into a digital ledger. Agentic commerce promises a shop that sells straight to your AI assistant. Whoever holds the rails earns on every train, no matter whose model is riding it.
Whose work the machine learns from
The third side is the most uncomfortable one. Models learn from texts, pictures and music that somebody made. On May 9, 2025 the US Copyright Office released a pre-publication version of Part 3 of its report on copyright and AI, the part about training generative models. American courts are still deciding where fair use ends, and the record labels are already suing platforms that write songs with AI.
Fashion is a separate case. Haute couture lives off the hand that sews and a name that can't be copied. It's the test of whether a craft keeps its value when everything around it can be generated in seconds.
The three questions
When you read about a new deal, ask three things: who pays, who takes a cut, and whose work is the raw material. The answers are rarely in the headline.
