Where are you getting the idea that RISC-V is dominant? As someone who works in this space, that doesn't jive with my experience or the sources I've seen.[1] 32-bit microcontrollers only recently achieved a majority market share for gosh sakes!
RISC-V is claiming that they have achieved 25% market share across selected segments, but they're still behind ARM (and x86).[2]

Risc-v is nowhere near dominant, people are just being swayed by headlines such as Western Digital or Nvidia shipping billions of risc-v cores.
I do find it odd that you go on and compare to x86 marketshare however, the topic you've quoted is very clearly about MCU and whilst 8086 MCU still exists they haven't been used in greenfield projects for decades. Let alone any more recent x86 implementation.
It's used widely in Chinese stuff (which is basically everything) so in terms of volume it's probably already dominant.
In terms of dollar volume ARM is still the leader, especially for higher-end (application level MCUs) stuff. RISC-V MCUs with MMUs or MPUs are scarce at the moment.
