MiniMax Files for Mainland China IPO — Revenue Doubles to $300M+, New Flagship Model Imminent as AI Capital Supercycle Deepens

Chinese AI startup MiniMax Group Inc. filed regulatory paperwork on May 30 to begin preparations for a domestic listing on mainland China's stock markets, Bloomberg reported — just months after its January 2026 Hong Kong IPO that raised HK$4.8 billion (~$620 million USD). The mainland filing is a direct capital deepening move: annualized revenue has more than doubled in recent months to at least $300 million, per a separate Bloomberg report from May 28, and a new flagship model launch is reportedly imminent. MiniMax is positioning itself as an enterprise and developer-tier challenger to DeepSeek V4 Pro — which made its 75% price cut permanent on May 26 at $0.003625/M input tokens. The dual HK+mainland listing strategy mirrors Baidu Kunlunxin's approach (announced May 8 for a $14.6B dual HK Exchange + Shanghai STAR Market IPO) and reflects the broader Chinese AI sector's preference for domestic capital formation across both onshore and offshore markets simultaneously. MiniMax had previously ranked #4 globally on AI model benchmark boards (Bloomberg/OpenRouter data, April 19, 2026), behind only Google, Anthropic, and OpenAI, with valuation at $40 billion+. The mainland IPO would give MiniMax access to a broader domestic retail investor base for continued model development and inference infrastructure buildout on domestic Huawei and domestic ASIC chips. The filing comes as China's AI unicorn wave accumulates: DeepSeek (~$50B, Big Fund-led), MiniMax ($40B+), Moonshot AI ($20B, May round), Kunlunxin ($14.6B dual IPO), and Zhipu AI (~$14B) now collectively exceed $135B in combined AI sector capital formation — all structured without US market access or foreign capital involvement. The MiniMax mainland filing marks the latest structural milestone in what analysts are calling China's AI IPO supercycle.
