Merchant ARM server is mostly dead unfortunately. Hyperscalers like AWS are making their own SoCs in house however. Amazona acquired Annapurna labs for that purpose.
Personally I see there being more market overlap between ARM and the P550 core however. Samsung, Qualcomm, Renesas are all planning to bring RISC-V cores to market. With performance between A75 and A76, I could see the P550 being a pretty major disruptor. We already know some RISC-V chips are gaining traction in embedded, IoT, RF, micro-controllers, etc. Automotive looks like the next big market for RISC-V to me.
