Microsoft's $7.443 Billion Trading Day Sees Stock Rise Amid Tensions with OpenAI

On June 16, 2025, Microsoft's trading volume reached $7.443 billion, ranking seventh in the day's stock market activity. Microsoft's stock price increased by 0.88%.

Tensions between Microsoft and OpenAI have escalated to a critical point, threatening their renowned AI partnership. Executives at OpenAI are reportedly considering accusing Microsoft of anticompetitive behavior during their current business relationship. This partnership, which began in 2019, has seen Microsoft invest $14 billion into OpenAI, the company behind ChatGPT and other AI technologies.

OpenAI is now exploring ways to reduce its dependence on Microsoft, including adopting Alphabet's Google Cloud service to meet its growing computing needs. This move has intensified tensions between the two companies, as Microsoft previously relinquished its observer seat on OpenAI's board to address antitrust concerns. The potential fallout from this dispute could severely damage one of the most significant technology partnerships in the AI field, potentially ending the relationship altogether.
