Tom Clancy’s Rainbow Six Siege is owned and published by Ubisoft , but the game is now operated under a Ubisoft-controlled subsidiary called Vantage Studios, in which Tencent holds a minority stake of around 25%.

Who legally owns Rainbow Six Siege?

  • The Rainbow Six brand and Siege itself remain intellectual property of Ubisoft, a French video game publisher.
  • Ubisoft created a dedicated subsidiary to house major franchises like Rainbow Six, Assassin’s Creed, and Far Cry, but Ubisoft still retains overall control of that subsidiary.

What is Vantage Studios’ role?

  • In 2025, Ubisoft regrouped several flagship series into a new entity later named Vantage Studios , which now runs Rainbow Six Siege day to day.
  • Vantage Studios has “complete creative and business control” over these franchises internally, while still sitting under the broader Ubisoft corporate umbrella.

Where does Tencent fit in?

  • Tencent invested about €1.16 billion for a 25% minority stake in the new Ubisoft subsidiary that includes Rainbow Six, giving it significant but non‑controlling financial interest.
  • Ubisoft remains the majority owner and decision maker, with Tencent acting as a strategic investor rather than the main rights holder of Rainbow Six Siege.

Simple takeaway

  • Legal IP owner: Ubisoft.
  • Operating studio: Vantage Studios (a Ubisoft subsidiary).
  • Major minority investor in that subsidiary: Tencent (about 25% stake).
