Interesting thought.

What specific protected class is "harmed" by personalized pricing?

And how would you prove that the model discriminated against them based on a protected element?

You can’t charge black people systemically different prices than white people, for example. Neither better nor worse prices. Proving causality would likely be the hard part, but a systematic survey of disparate pricing could show disparate impact. AI models frequently are invisibly biased on race because of some feature that operates as a proxy measure that the developers don’t recognize. eg something as simple as ZIP code combined with a name is a highly reliable predictor of race, and there are many similar, far more subtle ways bias can creep into a model.

All of them as they’re being used to compete and discriminate against each other.

That's not really how it works in the US. You have to prove that you were dicriminated against based on a protected class.

Everyone getting different prices doesn't mean its illegal:)
