As noticed by Zac at WC:

As we reported earlier this year, HP has been working on getting a Verizon model of the Elite x3 out for sale. This is a device that's aimed primarily at business customers, however, consumers or fans are welcome to purchase this device from Microsoft if they wish.

The HP Elite x3 supporting Verizon makes this the first Windows 10 Mobile-shipped device to do so. Previously, the only Windows 10 Mobile handsets to support Verizon were older devices that were upgraded from Windows Phone 8.1...

...What's more, the Elite x3 is old, sporting a Snapdragon 820, 4GB RAM and 64GB internal storage. While still the most powerful Windows phone, it's no longer the running the latest flagship specs available on other platforms.

If none of this phases you, the HP Elite x3 on Verizon is available right now for $599. Head to the Microsoft Store and check it out if you're crazy enough.
