ARM is already around for decades and has a solid 100% market share in smartphone applications. It also has a very high market share in anything embedded, though there PowerPCs, Mips and others are still surviving. Not having to pay royalties for the CPU architecture and the architecture being quite extensible has a lot of charm. That is why completely new CPU designs these days start on RISC-V, especially in research. On the other side, there are plenty of ARM-IPs, so unless you are designing your own processor cores, it often is way more efficient for the project just to include the ARM-IP. I can see RISC-V might make quite an impact on embedded systems short term, but smartphone vendors basically buy what Qualcomm produces. Until they produce an equally powerful RISC-V based design for less money, they will of course stick with the current architecture.
