Microsoft has revealed it’s working on a mobile gaming app store to compete against Google Play and the Apple App Store. 

The company disclosed the plan in a filing to UK regulators, which was noticed by The Verge. The UK’s Competition and Markets Authority (CMA) is conducting an investigation into whether Microsoft should be permitted to acquire Activision Blizzard for nearly $69 billion. 

The government regulator is concerned the deal will reduce competition in the video game industry since Activision Blizzard is the developer behind several major gaming franchises, including Warcraft, Diablo, Overwatch, and Call of Duty. But on Tuesday, Microsoft sent a 33-page response defending its plan to buy the company. In the same document, the company also mentions how Activision Blizzard promises to bolster Microsoft’s secret effort to create a rival to the app stores from Google and Apple. 

“The Transaction will improve Microsoft’s ability to create a next generation game store which operates across a range of devices, including mobile as a result of the addition of Activision Blizzard’s content,” Microsoft wrote in the filing. “Building on Activision Blizzard’s existing communities of gamers, Xbox will seek to scale the Xbox Store to mobile, attracting gamers to a new Xbox Mobile Platform.”

Of course, Microsoft could build such a platform without the acquisition. But Redmond argues the various game franchises from Activision Blizzard are crucial in attracting consumers to try out the mobile game store.

“Shifting consumers away from the Google Play Store and App Store on mobile devices will, however, require a major shift in consumer behavior. Microsoft hopes that by offering well-known and popular content, gamers will be more inclined to try something new,” Microsoft added. 

The company also plans on building the mobile platform with Microsoft’s “Open App Store Principles,” which were announced in February. These principles have been designed to ensure third-party developers can sell their apps with fewer restrictions and requirements compared to Google Play and the Apple App Store. 

Microsoft didn't say if it plans to make its own games exclusive on the mobile gaming platform. The company didn’t immediately respond to a request for comment. However, in the filing Redmond wrote: “Microsoft has consistently voiced its commitment to continue to make games available for purchase on any platform on which they are currently available.”

Still, UK regulators may not be convinced. In a statement last week, the UK's CMA signaled it was still worried Microsoft will prevent Activision Blizzard games from reaching other platforms, which could also undermine competition in the cloud gaming arena.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
