the ROG Xbox Ally spiked in month one, then fell off sharply. Steam Deck still accounts for roughly half of every handheld gaming PC sold — and the whole category is smaller than you think.
Microsoft's handheld push was supposed to be the serious challenge to Valve. The ROG Xbox Ally launched October 16, 2025 across 45 countries, backed by Microsoft, Asus and AMD together. According to Circana's Mat Piscatella, it spiked in its first month and then fell off sharply — and it 'did not put a dent' in the Steam Deck, which still accounts for roughly half of all handheld gaming PCs sold as of mid-2026.

The number that reframes the whole fight
The most useful figure here isn't market share, it's the category total: roughly 6 million handheld gaming PCs sold, ever, across all brands. For comparison, the Switch 2 shipped nearly 20 million units in its first year alone. So the 'handheld PC wars' are a fight over a genuinely small pie — one that gets enormous coverage relative to its size because the people who buy these devices are exactly the people who read and write about hardware. Winning it matters less than the discourse suggests.
Why the Ally didn't break through
Price is the obvious culprit — the Ally X sits well above $500, pushing it out of impulse range and into 'this is my main gaming device' territory, where a desktop or laptop competes hard. The Steam Deck's advantage was never raw specs; it was SteamOS, a curated verified-compatibility system, and aggressive pricing that made it an accessory rather than a commitment. Windows handhelds keep running into the same wall: a desktop OS on a small screen with a controller is still a compromised experience, no matter how good the silicon.
One honest caveat on the data: these are Circana analyst estimates, not unit figures Microsoft has disclosed. But the direction is consistent with everything else visible — and it sits awkwardly beside Microsoft's ambitions for a 2027 next-gen platform and the July studio cuts. 'Xbox everywhere' is a compelling strategy; the handheld leg of it hasn't found its audience yet.
