The most promising RISC-V companies today have not set out to compete directly with Intel, AMD, Apple or Samsung, but are targeting a niche such as AI, HPC and/or high-end embedded such as automotive.

And you can bet that Qualcomm has RISC-V designs in-house, but only making ARM chips right now because ARM is where the market for smartphone and desktop SoCs is. Once Google starts allowing RVA23 on Android / ChromeOS, the flood gates will open.
