Financial Times has more details on the new fundraise closed by OpenAI. From the report: OpenAI has asked investors to avoid backing rival start-ups such as Anthropic and Elon Musk’s xAI, as it secures $6.6bn in new funding and seeks to shut out challengers to its early lead in generative artificial intelligence. […] During the negotiations, the company made clear that it expected an exclusive funding arrangement, according to three people with knowledge of the discussions. Seeking exclusive relationships with investors restricts rivals’ access to capital and strategic partnerships. The move by the maker of ChatGPT risks inflaming existing tensions with competitors, especially Musk, who is suing OpenAI. Venture firms are party to sensitive information about the companies they invest in, and close relationships with one company can make it difficult or contentious to also back a rival. But exclusivity is rarely insisted on, according to VCs, and many leading firms have spread their bets in certain sectors. Sequoia Capital and Andreessen Horowitz, for instance, have backed multiple AI start-ups, including both OpenAI and Musk’s xAI.
