Microsoft's OpenAI Ties Face Potential U.K. Antitrust Probe

Microsoft Corp.'s partnership with OpenAI Inc. is facing the potential of a full-blown UK antitrust investigation three weeks after a mutiny at the ChatGPT creator laid bare deep ties between the two companies. The Competition and Markets Authority said Friday it was gathering information from stakeholders to determine whether the collaboration between the two firms threatens competition in the UK, home of Google's AI research lab Deepmind. Microsoft fell 0.7% in premarket trading. Microsoft has benefited richly from its investments, totaling as much as $13 billion, in OpenAI. By integrating OpenAI's products into virtually every corner of its core businesses, the software giant very quickly established itself as the undisputed leader of AI among big tech firms.
