MiniMax eyes a Shanghai listing after a 400% run in Hong Kong

At a glance:

• MiniMax is exploring a dual listing on Shanghai’s STAR Market while keeping its Hong Kong shares.
• The company’s Hong Kong shares have risen roughly 400% since the January IPO, trading near HK$840.
• MiniMax raised about $619 million in the Hong Kong IPO, valuing it at roughly $6.5 billion.

What the filing says

MiniMax filed a notice with the Hong Kong Stock Exchange on Sunday indicating that it is formally exploring a listing on the Shanghai STAR Market, China’s tech‑focused board. The filing mentions that the company has entered a tutoring agreement – the first regulatory step required before an IPO on the mainland. Advisors have been hired to navigate STAR Market’s listing rules, but MiniMax cautioned that any share sale will depend on market conditions and regulatory approvals, a standard disclaimer that keeps the move speculative rather than definitive.

Why a dual A+H structure matters

A dual listing, known in China as an A+H structure, would give MiniMax yuan‑denominated shares on the mainland in addition to its existing Hong Kong‑denominated shares. This arrangement opens access to a deeper domestic pool of capital and to investors who are restricted from buying Hong Kong‑listed securities. For Chinese AI firms, raising onshore capital also aligns with Beijing’s policy push to fund home‑grown champions and to reduce reliance on U.S. financing and technology.

MiniMax’s rapid post‑IPO performance

MiniMax’s Hong Kong debut on 12 January priced shares at HK$165, raising roughly $619 million and valuing the company near $6.5 billion. The stock more than doubled on the first trading day and kept climbing, reaching about HK$840 by late May – a gain of roughly 400% from the offer price. Such momentum is rare in the region and provides a compelling narrative for a second capital raise, especially on a market that rewards high‑growth AI stories.

Backers and competitive landscape

Founded in 2021 by former SenseTime executives, MiniMax builds large‑language and multimodal models that generate text, audio, video and music, selling API access to enterprises and consumer apps. Its backer roster includes Alibaba, Tencent, the gaming studio miHoYo and IDG Capital, with cornerstone investors in the Hong Kong float such as Singapore’s GIC, Baillie Gifford and the Abu Dhabi Investment Authority. MiniMax sits alongside peers like DeepSeek, Moonshot and Zhipu, all racing to convert technical credibility into public‑market capital before their U.S. counterparts.

Regulatory and market hurdles ahead

While MiniMax has taken the first formal step, the STAR Market’s approval process is known for its rigor. The company must satisfy criteria around profitability, technology readiness and corporate governance, and any share issuance will still need final sign‑off from Chinese regulators. Moreover, broader geopolitical tensions could affect foreign investor appetite for mainland‑listed AI firms, even as domestic policy encourages yuan‑denominated fundraising.

Outlook for China’s AI IPO boom

MiniMax’s move reflects a broader trend of Chinese AI startups seeking home‑soil capital after spectacular overseas listings. With U.S. capital increasingly fenced off and Beijing emphasizing an independent AI stack, a successful STAR Market debut could set a template for other AI unicorns. If MiniMax secures a listing, it would not only deepen its balance sheet but also signal confidence in China’s ability to nurture AI champions without relying on foreign markets.
