I have recently noticed that e.g. ChatGPT, when used from a web browser, periodically sends unfinished prompts to their servers, namely to the `conversation/prepare` endpoint, without waiting for the user to actually send it.
This partial prompt data might potentially be used to "pre-warm" some kind of cache.
But it may also be used to track the user's writing cadence, error correction style and evolution of their stub ideas as they are being formulated into a prompt. I would assume that such data could also be sold to the advertisers.

I'm pretty sure it is used for this; but rather than for anything nefarious, my guess is that this info is then fed to a classifier model to ensure that users of ChatGPT-the-service (as opposed to the OpenAI inference API) are actual humans, rather than agents trying to circumvent having to pay API pricing.
Enough Meta executives have been hired there. Expect the same behavior over time.
I wouldn't be surprised if their privacy policy would say "what you send is private" and then it wouldn't apply to unfinished prompts on technicality
