The best rumors I know of, from SemiAccurate, are that Intel is running 10nm in only one fab to debug processes that will be used in their 7nm node. While they're at it they might as well sell the output, but that's still in the undetermined future.

Here's the article https://semiaccurate.com/2019/01/25/why-semiaccurate-called-... which claims of the 4 fabs initially slated to do 10nm 2 are installing EUV equipment characteristic for 7nm, and 1 has "backported" to 14nm, a node which is capacity limited, Intel is leaving money on the table.

What do you expect with the 10nm CPUs?
