EU antitrust regulators are asking Microsoft’s rivals and customers whether they are affected by the US tech giant’s proposals to seek UK approval for its $69 billion acquisition of Activision Blizzard, sources close to the company said. affair.

Last month, Microsoft offered to sell its cloud streaming rights to Ubisoft Entertainment after the UK’s Competition and Markets Authority (CMA) blocked the biggest gaming deal in history.

The European Commission approved the deal in May after Microsoft agreed to license popular Activision games, such as “Call of Duty,” to rival game streaming platforms.

This authorization was given before Microsoft proposed the agreement with Ubisoft to appease the British regulator.

However, the EU antitrust watchdog has since sent emails to the companies asking for their opinion, the sources told Reuters. Sources said they had not launched a formal investigation, suggesting they could wait for the CMA’s decision before taking action.

It was not specified which companies were invited to provide comments. Companies generally prefer not to disclose their dealings with the Commission due to the sensitive nature of its investigations.

An EU investigation seems unlikely, according to other sources, citing the structure of Microsoft’s proposal to the CMA to ensure compliance with EU solutions.

The Commission declined to comment on the email and reiterated that it was closely monitoring developments in the UK and assessing any potential impact on its own case. (Reporting by Foo Yun Chee; Editing by Jason Neely and David Goodman)
