Hong Kong's stock exchange just posted its strongest first half in five years, and the banks actually running the deals are not the ones anyone would have picked a decade ago. The volume is real. The margins underneath it are not what the league tables suggest.

The Half That Broke the Record

Hong Kong-listed companies raised HK$209.9 billion across 85 new listings in the first six months of 2026, a 92 percent jump in proceeds and the busiest opening half since 2021 3. The first quarter alone brought in HK$109.9 billion across 40 deals, up 489 percent year over year, with fifteen completed A+H listings -- companies already trading on a mainland exchange adding a Hong Kong line -- accounting for 60 percent of the total, versus just one such deal a year earlier 3. PwC has since lifted its full-year forecast to roughly HK$380 billion, a level that would make 2026 the exchange's busiest fundraising year on record 6. The pipeline behind those numbers keeps growing rather than thinning: application volume more than doubled from 160 filings in June 2025 to 414 by early this year, with 96 new applications lodged in January alone 2.

Who Is Actually Winning the Deals

The mechanics of who underwrites those listings have shifted further than the headline totals suggest. China International Capital Corporation, the state-controlled house that dominates mainland banking, raised US$3.23 billion across 36 Hong Kong transactions in the first half and took the top ranking in both the Hong Kong and mainland markets with a 12.23 percent share 1. Chinese banks collectively now take close to 70 percent of Hong Kong's IPO fee pool, worth $579 million last year, up from 48 percent in 2019 2. That is a structural reversal of a market Goldman Sachs, Morgan Stanley and UBS effectively ran for two decades, and it lines up neatly with Beijing's stated goal of building a financial superpower by 2035 1.

The catch is profitability. CICC's expected return on equity sits around 6.6 percent, against the 13 to 15 percent range global banks such as Goldman Sachs, Morgan Stanley and JPMorgan post 1. Winning the league table has not meant winning the margin -- Chinese banks are pricing aggressively to build mainland relationships and lock in future mandates, a strategy that pays off in market share and in Beijing's industrial policy while compressing the economics of any single deal.

The Talent Bottleneck Behind the Numbers

Hong Kong's Securities and Futures Commission has already flagged the strain this volume is putting on the banks processing it. It warned 13 investment banks, together responsible for roughly 70 percent of listing applications, over serious deficiencies in their IPO filings, and it capped the number of live mandates a single signing principal can run at six 2. Some Chinese houses are pulling staff from mainland offices or relocating bankers to Hong Kong to keep pace, even as CITIC, CICC and several foreign banks have trimmed Asia investment-banking headcount since 2023 2. The result is a market processing more deals with a workforce that has not grown to match, a bottleneck that raises the odds of exactly the kind of filing errors the regulator is now policing.

Shein Is the Test Case

The listing that will show whether this machine can absorb a genuinely hard deal arrives this month. Shein is targeting a US$30 billion to US$40 billion valuation for a Hong Kong IPO it hopes to launch as early as mid-August, after the China Securities Regulatory Commission cleared the filing on July 10 4 5. That range is a steep reset from the US$98.2 billion the fast-fashion retailer commanded in 2022 and the roughly US$64 billion private investors paid in 2023 and April 2024 4. To get late-stage backers to accept the markdown, Shein is discussing cash payouts and bonus shares issued at a lower conversion price, effectively asking new public investors to absorb losses the company will not book on its own balance sheet 4. Revenue growth has already decelerated to 8 percent in 2025 from nearly 21 percent the year before, and the first quarter of 2026 brought a US$99 million loss after Washington closed the import-duty exemption Shein's US logistics model depended on 5.

What It Means for Investors

Hong Kong's exchange is not short of activity beyond retail and financials. Robotics and advanced-manufacturing names such as AgiBot, which hired Citic Securities, CICC and Morgan Stanley as joint sponsors for its own listing process in July, show the pipeline extending well into the sectors Beijing wants to promote 7 8. But volume and margin are diverging in ways that matter for two different trades. Investors backing the Chinese banks capturing this deal flow are buying market share at a discount to global peers' returns, a bet that only pays off if mainland relationships convert into higher-margin business later. Investors weighing the Shein listing are being asked to price a brand in genuine distress at a valuation still close to three times its return on the earnings trajectory alone would imply, cushioned by side payments that mask the real clearing price. Both bets share the same underlying wager: that Hong Kong's exchange has become too central to Asian capital formation to bet against, even when the individual deals running through it are not, on their own numbers, all that attractive.
