Microsofts trading volume drops 33.25% to $49.97 billion ranking ninth in daily stock market activity amid escalating tensions with OpenAI over $3 billion acquisition

On June 17, 2025, Microsoft's trading volume reached $49.97 billion, a 33.25% decrease from the previous day, ranking ninth in the day's stock market activity. Microsoft (MSFT) shares fell by 0.24%.

Tensions between Microsoft and OpenAI have escalated significantly, with reports indicating that the two companies are at a standoff over the terms of OpenAI's $3 billion acquisition of the coding startup Windsurf. This dispute threatens to spill over into the U.S. legal system, as OpenAI seeks to loosen Microsoft's control over its AI products. The situation has become so contentious that OpenAI is considering accusing Microsoft of anticompetitive behavior before federal regulators. This potential legal action could have far-reaching implications for both companies and the broader tech industry.

OpenAI's frustration with Microsoft has grown, leading to discussions about making antitrust complaints to federal authorities. The possibility of a lawsuit for antitrust violations adds another layer of complexity to the already strained relationship between the two companies. If OpenAI were to walk away from Microsoft, it would be a significant shock to the industry, given the substantial contracts and financial investments involved.
