Sony has inadvertently disclosed the financial impact that Microsoft’s acquisition of Activision Blizzard would have on its business. The company filed paperwork with the Federal Trade Commission (FTC) to demonstrate how the acquisition would affect Sony’s finances. The argument was that Sony would experience significant revenue declines as a result of the popular “Call of Duty” franchise becoming an Xbox exclusive.

An analysis of the redacted paperwork by The Verge revealed that “Call of Duty” games generated approximately $800 million for PlayStation in the United States in 2021. While the exact global figure cannot be confirmed, the document suggests that the franchise could be worth over $1.5 billion worldwide for PlayStation. Furthermore, the document appears to disclose that the value of the franchise itself for Sony is $13.9 billion or more.

Currently, only one more “Call of Duty” game is planned to be released on both PlayStation and Xbox, and Sony claims that one million players exclusively play the franchise’s releases. The future of the hearing is uncertain since the paperwork and related exhibits were removed after their discovery.
