For antitrust purposes below-cost pricing is not expressly illegal. It is only illegal if there is a “dangerous probability” that the firm in question will be able to recoup its losses after eliminating its competitors by taking away all their demand and then jacking up prices when they’re the only game in town. In the case of your Claude tokens, even if they’re being sold below cost, they’re being sold for more than anyone else is selling tokens. So it’s hard to argue that they’re going to drive everyone else out of the market with their pricing.
