The most accurate valuation for the recent IPO of China’s largest memory chipmaker did not come out of Shanghai. It actually came out of a derivatives market that Chinese law does not recognise, hosted on a venue no mainland investor can legally reach, and it was published 12 days before the stock existed.
On July 15, a small protocol called Trade.xyz opened a synthetic market on ChangXin Memory Technologies using Hyperliquid’s permissionless listing framework. The market closed its first session at $7.42 a share.
Twelve days later, on July 27, on the Shanghai Stock Exchange at 49.50 yuan ($7.32). The underwriters, the ones with the audited accounts and regulatory mandate, had priced the deal at 8.66 yuan, meaning they came in 82.5% below where the stock actually opened. Meanwhile, a market with no legal standing missed by just 1.4%.
Before anyone declares book-building obsolete, there is a very real caveat: The contract did not maintain its accuracy the entire time. It drifted for 10 sessions, bottoming 16% under the eventual open, and was still 9.5% light when the bell rang. Its best guess was its first, not its last.
Even so, in May, Cerebras also landed 1.3% from its cash open while the underwriters sat 47% below it.
The wall that built the market CXMT was the biggest IPO in Asia so far this year, and almost nobody outside China could buy a share. Northbound Stock Connect admits STAR Market companies only if they sit in the SSE 180 or 380 indices or carry a Hong Kong listing. A company two days old has neither. Even inside China, retail investors need 500,000 yuan in assets to trade the board. So, the demand went where blocked demand always goes. Six crypto trading venues listed some sort of claim on CXMT, with Hyperliquid capturing 92% of the open interest. Binance did not touch it despite running a SpaceX book in May, and even on Hyperliquid, only one of nine builders deployed it. That one builder, however, had a lot of willing counterparties.
Many people now claim offshore traders moved CXMT’s price on the Shanghai Stock Exchange. They did not, nor could they have. These derivatives contracts are cash settled, so no share is ever delivered into China. Open interest peaked near $79 million against an $8.55 billion raise, which is well under 1% of the deal. Plus, mainland retail investors are the ones who actually set CXMT’s price in Shanghai, and Hyperliquid still remains illegal for them. More proof came on day two of trading when global memory stocks fell hard. Kioxia dropped 17%, SanDisk 15%, SK Hynix 13%, and Micron 9%. Even GigaDevice, a fellow Chinese memory company listed in Shanghai, fell 16%. CXMT finished the same window up 1%. Figure 2.

Alice Liu Meanwhile, all five venues pricing CXMT offshore marked it 3%-5% below Shanghai’s close, and funding turned negative on every one of them, reaching 6.5% a day on Hyperliquid.
The argument is that foreign capital wanted CXMT lower, but there was no way to deliver a share into Shanghai to make that happen. So, the pressure went into the basis and sat there, with longs paid a fortune to hold the other side. Capital controls were not being circumvented, instead they were being repriced.
What SpaceX already taught us Six weeks earlier, the same machinery ran on SpaceX and got its debut roughly right. Then it kept going. SpaceX was priced at $135 and closed its first day at $161 . The pre-listing market had said $155, so let’s call that a win. Four days later, the same contracts printed $228.74, some 69% above the offer. SPCX has fallen almost every week since, slipping below its own IPO price in mid-July , and trades at $115.68 at the time of writing. Anyone who bought at the first-day close is down 28%, while anyone who paid $200 for early access is down 42%. Figure 3. SpaceX from the launch of its pre-IPO market to today vs. its $135 IPO price.

Source: Hyperliquid, Trade.xyz Alice Liu The structural contrast matters more than the numbers. A Nasdaq share can be held by a custodian, so tokenized SpaceX traded alongside the perpetuals and kept its peg. CoinMarketCap Research found tokenized SPCX tracked the $135 offering closely, while the derivatives ran 30% above it . An A-share, however, cannot be custodied offshore at all. SpaceX buyers got a claim on a company, while CXMT buyers could only ever get a bet on one.
