OpenAI is reportedly close to completing a $40 billion funding round led by SoftBank, according to Bloomberg. This new funding will include contributions from Magnetar Capital, Coatue Management, Founders Fund, and Altimeter Capital Management. SoftBank is expected to invest $7.5 billion initially, with an additional $2.5 billion coming from other investors. Following this, a second tranche later this year could see another $22.5 billion from SoftBank. This funding round would elevate OpenAI's valuation to an impressive $300 billion, up from $157 billion with its last round in October 2024.
