Microsoft feared that OpenAI might jump to Amazon and badmouth Azure “on the way out” — internal emails revealed in court
According to court documents revealed during the Musk v. Altman trial, Microsoft executives expressed significant concern over OpenAI’s potential move to Amazon Web Services (AWS). Internal emails showed that Microsoft feared OpenAI might abandon Azure, the company’s cloud platform, to handle OpenAI’s substantial $300 million annual cloud bill elsewhere. The correspondence revealed Microsoft was worried not only about losing this major customer but also that OpenAI might publicly criticize Azure’s capabilities “on the way out” if the transition occurred.
The court case, filed by Tesla CEO Elon Musk, centers on allegations that OpenAI’s leadership, particularly CEO Sam Altman, committed fraud and engaged in racketeering. Musk claims he was defrauded out of billions of dollars invested in OpenAI and argues the company abandoned its founding non-profit humanitarian mission after transitioning to a hybrid structure following his departure. The ongoing litigation continues to reveal previously confidential details about internal operations and business relationships within the AI industry, highlighting the significant commercial stakes involved in maintaining partnerships between major tech companies during a critical period of AI development and competition.
