Shanghai's retail bid marked CXMT's $8.6bn float at $48.7bn in one session
Chinese issuers are raising money into a domestic bid that then multiplies it by five, which says more about rationed supply than about durable AI earnings. Shein, the non-AI name in the queue, got the residual.
The Investor · Invest desk

What happened
- Shein's shares were due to begin trading in Hong Kong on Tuesday after an offering that raised $1.7bn, one of the city's largest new share sales this year, having earlier weighed US and London venues.
- CXMT, China's largest memory chipmaker, raised more than $8.6bn in Shanghai in July in the STAR market's second-largest listing, and its stock closed the first session 466% higher.
- Unitree, a leading Chinese humanoid robot maker, debuted in Shanghai in August with a 460% first-day gain, and by Friday the shares were more than 40% below that debut-day peak.
Why it matters
- What it costs cost The gap between issue price and first-day close is paid by CXMT's pre-listing owners, who parted with stock at under a fifth of what the market would clear, and collected by whoever received allocation.
- What it limits constraint A bid that concentrated on AI hardware leaves consumer names paying in dilution instead, which is how Shein hands over roughly 6.3% of itself to raise $1.7bn.
- Who's exposed exposure Because the Shanghai book is dominated by retail investors, drawdowns on debut-day marks land on households rather than on the institutions that were allocated at the offer price.
- What it sets up precedent Price discovery for China's AI supply chain is settling in venues foreign money largely cannot enter, so outside investors will keep reading valuations they can neither take nor arbitrage.
Multiply out what a 466% first-day gain does to a book: CXMT sold more than $8.6bn of stock in Shanghai in July, and the close marked that same slab at roughly $48.7bn, a difference near $40bn that accrued to whoever held the allocation rather than to the company's cash line [21]. Shanghai's market, as S&P Global Market Intelligence's Ruiying Zhao notes, is heavily driven by retail investors [12], and a bid willing to pay 5.66 times issue is telling you the binding constraint is supply of paper, not appetite for it.
The venue arithmetic points the same way. LSEG puts Hong Kong and Shanghai at over $54bn of IPO and secondary proceeds so far in 2026 against more than $46bn for all of last year, about 17% higher with the year unfinished [9][24]. Against Nasdaq's roughly 55% of global proceeds, that 21% back-solves to a worldwide pool near $257bn, which means SpaceX's $75bn June listing on its own out-raised the two Chinese exchanges combined by some $21bn and took about 29% of the world's IPO money [11][23]. Two exchanges, or rather two exchanges and a captive savings pool, against one deal.
The strongest case against calling any of this overheated is CXMT's revenue, up more than 700% year on year to 50.8bn yuan, about $7.5bn, in the first three months of 2026 on demand for AI chips [8], which makes the entire raise roughly 1.15 times a single quarter of sales [25]. Perris Lee of ION Analytics reads the deal as a testament to China's tech self-sufficiency ambitions [15], and on the cash he has a point: a memory maker compounding at that rate can grow into almost any first-day mark.
This is probably wrong, but I think the pops price enclosure rather than earnings. Mainland exchanges limit foreign buying, which is why parallel Hong Kong listings exist at all [16]; the overseas route takes longer, according to Freshfields' Howie Farn [18]; and tighter scrutiny on both sides has pushed strategically sensitive issuers home [17]. Rationed supply meeting money that cannot leave produces five-baggers more or less regardless of what sits underneath. Unitree is the cleanest read on that, up 460% on day one in August and then down more than 40% from the debut peak by Friday, which still leaves it near 3.4 times its issue price if that peak sat close to the debut close [26]. The drawdown has not yet reached the money.
What would prove me wrong is dull and checkable: the 2026 cohort still trading above its debut closes a year out would mean the books were priced conservatively into demand that was real, and that underwriters, not households, misjudged. Zhao's own test is whether AI sentiment alone is enough, with a durable cycle requiring sustainable revenue and visible margins [13]. Jacob Cooke of WPIC Marketing + Technologies supplies the other half, that the AI investment cycle is absorbing risk appetite that would otherwise have flowed to a company like Shein [14]. Money going into memory fabs and humanoid legs is money not underwriting consumer platforms, and that is how a fast fashion giant takes a mark far below its peak valuation [2] while selling paper into a queue where it is the least interesting name on the screen.
What to watch
- Whether AGIBOT and Deep Robotics price their Hong Kong or Shanghai books wide enough to leave a flat first day rather than another five-bagger.
- CXMT's next quarterly revenue print against the 50.8bn yuan base, since a cooling memory cycle removes the earnings defence for its debut mark.
- Shein's secondary trading against the $27bn IPO mark as a gauge of how much risk appetite the AI cycle is still absorbing.

Unitree, one of China's leading humanoid robot makers, made its listing debut in Shanghai in August and its shares rose 460% on the first day of trading.
- [7]
Unitree's share price had fallen more than 40% as of Friday from its peak share price on the day of its trading debut.
- [8]
Founded in China in 2016, CXMT's revenue surged more than 700% year-on-year to 50.8 billion yuan (about $7.5 billion) in the first three months of 2026 on a spike in demand for computer chips needed for AI.
- [9]
LSEG says IPOs and secondary listing activity on the Hong Kong and Shanghai exchanges raised a total of over $54 billion so far in 2026, surpassing last year's total of more than $46 billion.
- [10]
LSEG says combined Hong Kong and Shanghai proceeds so far this year accounted for roughly 21% of the global total, behind only Nasdaq's roughly 55% global share.
- [11]
The $75 billion IPO by SpaceX in June made the US exchange the world's biggest IPO market this year.
- [12]
Ruiying Zhao, a senior research analyst at S&P Global Market Intelligence, said the current IPO boom is powered by investor appetite for AI and robotics, and that trading in Shanghai's stock market is heavily driven by retail investors.
- [13]
Zhao said the critical question remains whether AI sentiment is enough, and that for a durable market cycle investors will demand sustainable revenue, visible profit margins and realistic valuations.
- [14]
Jacob Cooke, CEO of WPIC Marketing + Technologies, said the AI investment cycle is absorbing much of the risk appetite that would otherwise have flowed to a company like Shein.
- [15]
Perris Lee, head of APAC equity capital markets for ION Analytics, said CXMT's Shanghai IPO placed China in a strategically significant position in tech manufacturing related to AI and is a testament to China's tech self-sufficiency ambitions.
- [16]
Since China limits foreign purchases on mainland exchanges, many Chinese companies do parallel listings in Hong Kong to help raise international capital.
- [17]
Stricter US and Chinese regulatory scrutiny of big Chinese companies listing in US markets, especially in strategically important sectors such as advanced technologies, has led some Chinese companies to stick closer to home.
- [18]
Howie Farn, a capital markets partner at Freshfields, said listing overseas typically takes more time compared with doing IPOs in China.
- [19]
Robotics firms AGIBOT and Deep Robotics are among more companies looking to hold their IPOs in Hong Kong or Shanghai.
- [20]
Recent Hong Kong listings of Apple supplier Luxshare Precision Industry and Zhongji Innolight, which makes optical transceivers used in data centres, were among this year's largest deals and reflected investor demand for advanced technologies.
- [21]
A 466% first-day gain implies a close at 5.66 times the issue price, so the stock CXMT sold for more than $8.6bn was marked at roughly $48.7bn by the close, about $40bn above the proceeds raised.
- [22]
Raising $1.7bn at a value of about $27bn means Shein sold roughly 6.3% of the company.
- [23]
If Hong Kong and Shanghai's $54bn is about 21% of global proceeds, the global pool is near $257bn, making SpaceX's $75bn deal about 29% of it on its own and roughly $21bn larger than the two Chinese exchanges combined.
- [24]
More than $54bn raised so far in 2026 is about 17% above last year's full-year total of more than $46bn.
- [25]
CXMT's raise of more than $8.6bn is about 1.15 times the roughly $7.5bn of revenue it reported for the first three months of 2026.
- [26]
A 460% first-day gain is 5.6 times the issue price, so a fall of more than 40% from the debut peak leaves Unitree at roughly 3.4 times issue, assuming the debut peak sat close to the debut close.
