What Microsoft bought

Microsoft has made some of the biggest tech buys ever. One — a game maker — cost as much as the other five combined.

Numbers as of 20 Aug 2026

Six deals, in the order the money left.

Skype, 2011, $8.5bn. The video-calling service, shut down in 2025. Its tech fed into Teams.

Nokia's phone business, 2014, $7.2bn. Within two years Microsoft wrote off $7.6bn — nearly all of it — and left phones.

LinkedIn, 2016, $26.2bn. The professional network, Microsoft's biggest deal for seven years.

GitHub, 2018, $7.5bn. Where most of the world's code lives.

Nuance, 2022, $19.7bn. Speech recognition and healthcare AI, almost unknown outside IT.

Activision Blizzard, 2023, $68.7bn. Call of Duty, World of Warcraft, Candy Crush. Nearly two years and regulators on three continents to close.

The shape worth noticing: the other five add up to about $69bn. Activision alone was $68.7bn. One deal, the size of the other five.

Two caveats. These are announced values, not what was ultimately paid or written off — Nokia and Skype are the obvious cases. The $138bn is these six added up, not Microsoft's total M&A.

Next week: the one on this chart Microsoft wrote off almost entirely.
