MiniMax, a prominent model company, is on the verge of concluding a new funding round of approximately $300 million, pushing its post-investment valuation beyond the $4 billion mark. This follows a $3 billion funding round completed by the company at the end of last year. Earlier this June, reports emerged indicating MiniMax's preparations for a Hong Kong listing. At present, MiniMax and Zhipu stand as the sole large model companies in China to have attained this impressive valuation.
