HKD 255 Billion Unlocks on July 7
The Manufactured Supply Squeeze
Hong Kong raised HKD 3 billion across 78 listings in the first half of 2026, a 90% jump in proceeds versus the same period last year, according to Deloitte China's June review, enough to push HKEX to second globally in H1 fundraising, behind a Nasdaq that happened to catch the SpaceX listing. Those are genuinely large numbers. What made them possible is worth naming precisely: 85% of H1 offerings featured cornerstone investors, now a coalition of state-owned entities, sovereign wealth funds, and provincial governments, according to EY China's June analysis. Cornerstone investors are anchor buyers who commit to a fixed allocation before the IPO prices and agree, under HKEX's standard framework, to hold their shares for 180 days. That commitment reduces the retail public tranche and keeps aftermarket volatility manageable, because the float available to ordinary buyers is deliberately compressed. So what the boom actually produced was pricing supported by a committed bid against a thin secondary market. The valuations on the AI cohort, MiniMax, Knowledge Atlas Technology, and the other Chapter 18C names (biotech and advanced-technology companies admitted under a separate HKEX listing chapter that relaxes revenue requirements) in the H1 vintage, were set in that environment. July 7 is the first day those prices meet a market with a full float.
Two Unlocks, One Sector Re-Rate
China Daily HK reported that HKD 255 billion in cornerstone and pre-IPO shares unlock in July 2026 alone, the highest monthly peak across the full calendar year. Knowledge Atlas Technology releases its cornerstone shares on July 7. MiniMax releases 5 million cornerstone shares on July 8. That sequencing matters because the AI names in the H1 vintage are not priced in isolation. A fund manager running an HK tech basket looks at MiniMax and Knowledge Atlas as the reference data points for the whole cohort. If both names reprice simultaneously because the southbound mainland bid, the flow of mainland Chinese capital into Hong Kong equities through the Stock Connect link, that anchored the cornerstone books does not reappear at the same scale, the discount does not stay contained to those two tickers. It becomes the cohort's new par. EY's sector breakdown puts IT at 32% of the full 2026 lockup expiry volume. The arithmetic does not require a selloff. It requires only that the southbound bid on July 7 and July 8 be smaller than the supply those two names release.
KPMG's April forecast put full-year 2026 Hong Kong IPO proceeds at HKD 350 billion, implying a second half that replicates the first on the same cornerstone logic. The listing desks at HKEX and the southbound flow desks at the major mainland brokerages will have their answer by July 22, two weeks after Knowledge Atlas and MiniMax both trade on full float. If the bid holds, the H1 structure transferred price risk cleanly. If it does not, every Chapter 18C name still in the pipeline enters a market with a revised par.
