In an interview with the Financial Times, Microsoft’s gaming chief Phil Spencer said the app’s launch hinges on regulators approving the company’s acquisition of video game maker Activision Blizzard, as this would give Microsoft a wider portfolio of mobile games. Second, the app would only be able to launch if the EU’s Digital Markets Act and other regulations allowing for alternative app stores on iOS are enforced.

“We want to be in a position to offer Xbox and content from both us and our third-party partners across any screen where somebody would want to play,” Spencer told the Financial Times. “Today, we can’t do that on mobile devices, but we want to build towards a world that we think will be coming where those devices are opened up.”

In December, Bloomberg‘s Mark Gurman reported that Apple was preparing to allow alternative app stores on the iPhone in order to comply with the Digital Markets Act, which is expected to come into effect in March 2024. Gurman said Apple was aiming to roll out the changes with an iOS 17 update next year for iPhone users in Europe only. This means the Xbox games store would not be available in the U.S., at least initially.

Xbox already offers a cloud gaming service on the iPhone, but games are only playable via the web instead of the App Store. Apple has faced increasing regulatory scrutiny over its tight control of the App Store, leading the company to make changes in some countries, such as allowing alternative payments in South Korea.
