China’s biggest IPO in over a decade doubled as the first real scorecard for crypto’s pre-IPO shadow markets, and the result depends entirely on which number you measure against.
China’s Biggest IPO Since 2010
ChangXin Memory Technologies, or CXMT, priced its Shanghai STAR Market listing at 8.66 yuan a share and raised 57.92 billion yuan, about $8.6 billion, rising toward $9.8 billion with the over-allotment. It is Asia’s largest IPO of 2026, the biggest mainland China listing since Agricultural Bank of China in 2010, and the largest semiconductor listing on a Chinese exchange since SMIC in 2020.
Then it opened at 49.50 yuan. Shares closed up roughly 470%, lifting CXMT to about 3.3 trillion yuan and past Industrial and Commercial Bank of China as the most valuable company listed on the mainland, on day one.
The debut was engineered to pop. CXMT is priced at just 2.4 times book, a 56% discount to global DRAM peers Micron and SK Hynix per Bloomberg Intelligence, with only 6.73% of shares freely tradable and a retail tranche oversubscribed 212 times. Nine-plus million retail orders chased a tiny float against the backdrop of a memory upcycle that lifted DRAM contract prices more than 90% quarter-on-quarter in early 2026.
The Perp That Front-Ran the Float
Two weeks before any of that, Trade.xyz launched a CXMT perpetual futures contract on the Hyperliquid blockchain, ticker xyz:CXMT, at a $5 reference price. It offered up to 5x leverage, settled in USDC, and conferred no ownership, dividends, or voting rights.
The contract climbed fast, peaking near $8.64 for an implied valuation around $500 billion, then settled back to roughly $6.35 in the days before the listing, implying about $425 billion. For global traders, it was effectively the only venue to take a position on the deal.
How Close It Really Got
Set the perp’s pre-listing range beside the outcome, and the picture is striking. CXMT actually debuted around 3.3 trillion yuan, roughly $460 billion; the Hyperliquid contract had been trading between about $425 billion and $500 billion implied for two weeks. On the metric that matters, where the stock actually traded, the shadow market was in the right neighborhood before a single share changed hands in Shanghai.
That is the sense in which Bloomberg’s report, that Hyperliquid priced CXMT near its eventual opening valuation, holds up. The contract was not forecasting the offer price; it was forecasting the market’s verdict, and it landed close.
The skeptical framing, that the perp implied a valuation several times CXMT’s $85.5 billion offer valuation, is technically true but misleading. That offer price was a deliberate floor: underpriced against peers, throttled to a sub-7% float, and swamped by 212x demand. Judging a market-valuation bet against an offer engineered to pop is the wrong test.
Why the Accuracy Comes With an Asterisk
Close is not the same as clairvoyant. The contract swung from $5 to $8.64 to $6.35, a wide band that happened to contain the answer rather than a tight estimate that pinned it, and thin liquidity in these early markets makes that price discovery approximate at best.
More fundamentally, the perp and the A-share debut were driven by the same force. The memory-chip mania and AI-DRAM upcycle that produced a 212x-oversubscribed order book are the same sentiment that bid the Hyperliquid contract up. The shadow market reflected the euphoria more than it independently discovered a price, and a Ventuals oracle malfunction that triggered a $1.5 million liquidation cascade in May is a reminder of how fragile the plumbing still is.
The Only Way In for Global Traders
The access gap is what gave the contract its reason to exist. Mainland A-shares are hard for foreigners to touch: Qualified Foreign Institutional Investor quotas involve approvals and paperwork, and Hong Kong Stock Connect does not cover STAR Market debuts on day one. For anyone outside China wanting exposure to a top-of-2026 IPO, the synthetic perp was functionally the only game available.
That mirrors the pattern crypto has run all year with still-private names like SpaceX and OpenAI, where demand surged the moment an access barrier dropped. CXMT is the first case where the underlying was actually listed, turning an unfalsifiable bet into a gradable one.
An Offshore Bet on a Chinese Chip Champion
The regulatory picture is uncharted, and pointedly so. CXMT is China’s largest DRAM maker and a national champion in a sector at the center of the US-China chip contest, and here an offshore, dollar-settled derivative let global traders price it before Beijing’s own market opened.
Chinese securities regulators have not publicly addressed synthetic contracts shadowing a domestic listing, and it is unclear whether Western regulators would scrutinize such products if US traders pile in. A crypto venue running a price-discovery layer on top of a strategic Chinese asset is the kind of jurisdictional grey zone that tends not to stay grey for long.
