MINIMAX Front-Runs an August Stock Connect Bid It Can't Reach Yet

The Stock Connect Race MiniMax Is Losing

MiniMax and Zhipu both joined the Hang Seng Tech Index on June 8, the first Chinese AI pure-plays in Hong Kong's benchmark tech gauge, at initial weights of 0.36% for MiniMax and 0.53% for Zhipu. Morgan Stanley sees those climbing to 5–7% over time, roughly US$1.25–1.75 billion of eventual passive inflows. That part is shared.

The bigger mechanical bid is Stock Connect southbound, and here the two names split. Zhipu was fast-tracked into the program the same day it joined the index because it carries a standard share structure. MiniMax's weighted voting rights (WVR) structure disqualifies it from that fast track — it isn't expected to qualify before August, about two months behind Zhipu. Bloomberg Intelligence pegs MiniMax's eventual southbound bid near HK$47 billion.

So when MINIMAX gaps on a Stock Connect headline, the market is front-running a flow that is structurally still weeks out. Worth remembering: inclusion day itself was a fade, not a bid. On June 8 MiniMax fell 8.4% to HK$506 into a broad regional slump.

Why the Cash Ripped and the Perp Faded

The June 22 leg was policy, not fresh fundamentals. The Hong Kong line closed up 23.89% at HK$616.50, extending a run that has left the stock around 270% above its HK$165 January IPO price. The accelerant is the same one driving the whole complex: China's June 17 STAR Market rule change clearing loss-making large-model firms to list in Shanghai, plus MiniMax's filing toward a mainland A-share dual listing.

The perp told a different story overnight. It printed above the Hong Kong cash close intraday, then round-tripped to $77.28 — back to a slight discount to its roughly $78–79 cash-implied value (HK$616.50 converted at the prevailing USD/HKD rate). This is the narrative that re-rated the entire Hong Kong large-model basket this month on US export curbs and a domestic model-release wave; the perp simply gave back its speculative premium and is now pricing the cash, not a fresh catalyst.

The July Cliff

The nearest dated catalyst points the other way. MiniMax listed on January 9, so its six-month IPO lock-up expires in early July, and it ranks among the July unlocks with the largest values — roughly HK$84.3 billion of pre-IPO and cornerstone stock coming free to sell.

HSBC is already positioning for it, cutting its MINIMAX target to HK$760 and moving to Hold, citing the impending lock-up and a wave of peer AI IPOs eroding the scarcity premium that powered the run. Short-sellers haven't waited either: during the June 8–9 index rebalance, short volumes in both MiniMax and Zhipu hit highs since late April, and Zhipu dropped 13.55% and 7.75% on the two sessions after its inclusion.

Underneath the listing story the fundamentals are thin: MiniMax booked just US$53.44 million of revenue across the first nine months of 2025 against about US$180 million of R&D. That loss profile is precisely why the STAR Market rule had to be rewritten for it to list at home — and precisely what makes a 270%-above-IPO valuation hostage to flows that, for MiniMax specifically, are still gated until August.
