The roughest guesstimate is around $3-5 per 1000 plays. But this varies hugely between platforms and also by artist (they may negotiate a special deal).
The graphic below details is what each platform distributes to artists per stream.
I did some napkin maths (potentially wildly inaccurate), from the articles I read - In the US during 2021, there were 840 BIllion songs streamed generating around $5 Billion revenue - works out to 0.059c per stream?
Not sure about that calculation, means the artists are getting around 5-10% of the $$$ generated by the stream. Although this does kinda reflect some of the rumbling I've read from artists.
