VMS is / was popular in the transaction processing industry: financials, lottery, casino, etc. However, most of the folks I know working in that industry moved on to other platforms over a decade ago.

I have an AlphaStation as part of my retro collection. It has OpenVMS on it, but hasn't been booted in a while.

A university I worked at migrated from independent VMS systems (student, finance, HR) to an ERP system. To make that implementation easier, they only converted the most recent few years of data.

Last I heard they had some sort of virtual machines emulating Alpha hardware still running those legacy systems.

My current employer (also higher ed.) is hosting somebody's ES40. Some people in higher ed. really, really liked VMS and the Alpha/Itanium platforms.

Some satellite broadcasting platforms still use VMS for mixing the data carrousel with the mpeg transport streams.

One of those services, millions use it everyday without knowing it.

I haven't worked there for a few years, but I'm 99% sure that German stock exchange in Frankfurt (https://www.deutsche-boerse.com/dbg-en) is still operating their clearing operations (central counterparty) and some others on OpenVMS/Itanium servers from HP

If you squint you could argue Windows NT is basically a cousin of VMS considering its origins and principle architect.

IKEA does. Their home grown ERP system run (ran?) on OpenVMS at each store [1].

Some hospital labs. The systems are scheduled to be replaced within a couple of years.

If you're dealing with anything Apple you're probably running macOS VMs on Apple hardware. At least for things like build servers, signing and such (CI/CD) when the projects start growing.
