Some of the biggest sports leagues in Call of Duty, Overwatch and Hearthstone will be broadcast exclusively on YouTube.
The deal is seen as a major victory for the platform, which found it difficult to compete with the game's serpentine, Twitch.
It is part of an agreement signed by the website with Activision Blizzard – the company that manages the leagues. Twitch broadcast exclusively the first two seasons of the Overwatch League and is seen as the preferred destination for live games.
The deal was announced just hours before the start of the Call of Duty League season, with 12 teams competing in Minnesota – and it could rock the gaming world.
"We have worked closely with Activision Blizzard over the past few years on mobile titles to increase its analytics capabilities and overall player experience," said Sunil Rayan, head of Google Cloud games.
"We are excited to now expand our relationship and help drive one of the largest and most renowned game developers in the world."
Despite being the largest video site in the world, YouTube has historically struggled to compete with sites like Twitch.
But in recent months, the platform has made some high-profile moves, stealing Twitch's streamer, Jack "CouRage" Dunlop, which has an average of more than 9,000 live viewers per stream.
And last week, YouTube announced exclusive deals with Rachell "Valkyrae" Hofstetter, Elliott "Muselk" Watkins and Lannan "LazarBeam" Eacott.
As part of the deal, the search giant's cloud platform will provide all of Activision Blizzard's game hosting and other technical needs.
Google Cloud will also host the entire Activision Blizzard game library.
