Elon Musk, a prominent US entrepreneur, has asked a US court to stop OpenAI's "illegal" transformation into a for-profit enterprise. A spokesperson for OpenAI said Mr. Musk's application was "duplicate and still baseless". In February, Mr. Musk filed a lawsuit claiming that while he was providing funding and other support for the founding of OpenAI, he had agreed with the company's two co-founders that OpenAI should be a "non-profit organization", but OpenAI violated its founding goals and mission and instead pursued profits. In June, Mr. Musk withdrew the lawsuit and re-filed it in August. In November, Mr. Musk escalated his case against OpenAI, accusing it of trying to monopolise the market for generative artificial intelligence.
