Starting today, you can sign up for a chance to reserve the Steam Machine, choosing from four different options:

All four options will have their own sign-up list, and you can sign up for multiple if you want. There are also separate sign-up lists for each shipping region, and Valve says it will automatically place you in the list for your region. There are currently four shipping regions: North America, the United Kingdom, the European Union, and Australia.

The sign-up window ends on June 25th at 10AM PT / 1PM ET. At that point, Valve will use a “one-time randomization” to determine the reservation order for everyone who signed up.

Regardless of how many lists you signed up for, you can ultimately end up on only one. If you get lucky and get randomly assigned a reservation spot for more than one model, Valve says you’ll automatically be given the reservation for the highest-end model you signed up for, and removed from any other sign-up lists you were on. Likewise, if you didn’t get a reservation spot at all, Valve says “you’ll be placed on the waitlist for the model that you were closest to the front of.”

On June 25th, Valve will send out emails to everyone who signed up letting them know whether they’ve been added to the reservation queue, meaning there’s a unit reserved for them, or the waitlist. If you sign up after June 25th, you’ll automatically be added to the back of the waitlist. Once these emails go out, you can’t change which Steam Machine configuration you signed up for.

Valve also has some eligibility criteria you’ll need to meet to sign up:

You must have a Steam account in good standing

You must have made a purchase on Steam prior to April 27th 2026

Limit one signup per household. We will use payment method, shipping address, and other information to eliminate multiple entries.

Landing in the waitlist means you’ll have to wait until more units of the configuration you signed up for are available. If you secure a reservation, Valve will give you 72 hours to complete your Steam Machine purchase. The first reservation emails are going out on June 29th.
