Confidential VM is essentially productizing AMD SEV technology. Intel will have something similar on the market in the (hopefully near) future. Given that AWS and Azure also use AMD and Intel equipment, I'd expect them to introduce similar functionality. (AWS is probably closer as SEV support is built into Linux, whereas Windows has no support for it as far as I can tell.)
