The cost of Xbox Game Pass Ultimate for brand-new subscribers has technically already gone up from $16.99 a month to $19.99 a month (at least when you sign up directly through Microsoft), but the change doesn't go into place for all users (including those on recurring billing) until Sept. 12, 2024. That date is quickly approaching, though, and it's expected that digital codes for Xbox Game Pass Ultimate will adjust prices following the broader price increase rollout.
