Generally speaking, B2B prices are rarely supply-and-demand priced in the usual sense.
YC has advised startups in the past that it's easier to sell a single $100k customer than 100 $1k customers.
It would also be relatively surprising to learn that i.e. the Chinese providers are OOMs better at inference than OAI/Anthropic (like their prices would imply if they were in a perfectly competitive market).
Chinese prices aren't really OOM cheaper. Deepseek recently did a big price hike too.
The one thing I trust is that Chinese prices aren't overinflated. They're almost certainly closer to the actual cost of inference + training amortization than what Western labs are offering.
DeepSeek's price hike is mostly driven by increased demand, for example. It's not about losses so much as they don't have enough infrastructure and need to reduce demand somehow.
Why do you have this trust? Are they not profit oriented? Or you suspect that Xi's policy push is to undercut American AI?
Fair, I hadn't looked recently. It looks like currently kimi is either 1/2 or 1/4 Ant pricing depending on whether you think Opus 5 is usable or not. (Deepseek is still an OOM though)
