04:59 PM EDT, 06/16/2025 (MT Newswires) -- Microsoft's ( MSFT ) partnership with OpenAI is under stress, with OpenAI executives weighing the option of accusing Microsoft ( MSFT ) of anticompetitive behavior, The Wall Street Journal reported Monday, citing people familiar with the matter.

The effort could include seeking a federal review of their contract for antitrust violations, the people reportedly said.

The companies are at a standoff due to the terms of OpenAI's $3 billion acquisition of Windsurf, according to the report.

Microsoft ( MSFT ) wants to expand its stake in OpenAI more than what the startup is willing to give, the sources reportedly said.

Microsoft ( MSFT ) and OpenAI did not immediately respond to MT Newswires' request for comment.
