A Beijing chip designer that most retail investors could not name a year ago suddenly became the most-watched ticker on China's technology board. On its first trading day the stock more than quadrupled, turning a company with no profit into a US$40 billion name before lunch. The question hanging over the rally was simple: is the market pricing a real GPU champion, or placing a bet on a policy that rewards ambition over earnings?
Key takeaways
- Moore Threads (摩尔线程) raised roughly RMB 8.0 billion (US$1.13 billion / HK$8.7 billion) in its STAR Market (科创板) debut on 5 December 2025, the largest Chinese GPU listing of the year.
- Shares closed at RMB 600.50, up 425% from the RMB 114.28 issue price, giving the firm a first-day market value near RMB 282 billion (US$39.8 billion / HK$308 billion).
- The company listed under the exchange's fifth criterion, which lets loss-making "hard tech" firms raise equity — a direct result of the "1+6" reform introduced in 2025.
- It remains deeply unprofitable: cumulative losses reached about RMB 5.9 billion (US$0.83 billion) from 2022 through the first three quarters of 2025.
- The listing shows China's capital markets are now funding sovereign-grade GPU ambitions through public equity, not only state-backed vehicles.
Why a GPU maker, and why now
Moore Threads (摩尔线程) builds full-function GPUs for AI training and inference, scientific computing, and graphics. Founded in 2020 by Zhang Jianzhong (张建中), a former Nvidia (英伟达) executive in Greater China, the company has launched four GPU architectures and positions itself as a domestic alternative to imported accelerators.
The timing matters. By late 2025, demand for locally designed compute had moved from a policy talking point to a procurement priority for Chinese cloud and state-linked buyers. A public listing gave the company a large, patient pool of capital that private rounds could not easily supply.
The "1+6" reform in practice
The offering was approved through the STAR Market's fifth listing standard, which permits firms without a profit history to list if they meet thresholds on R&D and valuation. This route was reopened and broadened by the "1+6" package of reforms rolled out in 2025, which also added a pre-review mechanism and a dedicated growth tier.
Moore Threads moved from application acceptance to registration in about 122 days, with only 88 days from acceptance to approval — among the fastest timelines the board has recorded. The speed was not an accident; it was the intended output of a rulebook written to shorten the path for "hard tech" (硬科技) firms.
Reading the valuation
At the RMB 114.28 issue price, the deal valued the company at roughly RMB 53 billion pre-money on a stated share count. By the close of the first session that figure had ballooned to about RMB 282 billion. For context, 2024 revenue was only RMB 438 million, and the first nine months of 2025 brought RMB 785 million — meaning the first-day market value sat at several hundred times trailing sales.
Investors were clearly not buying 2025 earnings. They were buying a call option on domestic GPU supply at scale, underwritten by a reform designed to keep such options listed and funded.
What the order book tells us
The deal sold 70,000,000 new shares with no secondary sales. Net proceeds of about RMB 7.58 billion (US$1.07 billion / HK$8.3 billion) were earmarked for next-generation AI training-and-inference chips, graphics chips, and AI system-on-chip designs. A small strategic allocation went to the lead underwriter's investment arm, a routine structure rather than a signal of weak demand.
The maker's intended raise was RMB 8.42 billion; the realized gross was slightly lower after fees, but the gap was immaterial. What was material was the aftermarket: a 425% first-day pop signals that supply of listed GPU exposure is scarce and that public money is willing to pay a steep premium for it.
What the listing signals for China's capital markets
Moore Threads' debut is a watershed for how China's public markets treat strategic technology. For most of the past decade, funding the country's semiconductor ambitions fell to state-linked vehicles and private capital operating out of the spotlight. A GPU designer reaching a first-day value in the hundreds of billions through an open, retail-accessible exchange marks a shift: sovereign-grade compute ambitions are now being underwritten directly by public equity, with ordinary investors sharing both the upside and the risk.
The episode also shows how far rule design can move markets. The "1+6" reform did not invent demand for domestic chips, but it removed the profit hurdle that had kept such firms off the board and compressed the time from application to listing. Whether that speed serves long-term allocative efficiency remains open; what is clear is that policy now actively steers public capital toward "hard tech," and the Moore Threads trade is the most visible proof that the mechanism works as intended — for issuers, if not yet for the buyers who paid the debut premium.
Honest limitations
This article relies on the company's prospectus and exchange filings plus Chinese financial press; it does not include management interviews or a proprietary financial model. The first-day price is a sentiment snapshot, not a fair-value estimate, and it has moved substantially since. Loss figures are cumulative and include non-operating items. Currency conversions use approximate rates (US$1 ≈ RMB 7.10, HK$1 ≈ RMB 0.915) and are rounded; they are directional, not audited. The "largest GPU listing of the year" claim reflects public Chinese listings in 2025 and may shift with later deals.
What readers can do now
- Treat the debut as a sentiment gauge for policy-supported semiconductor listings, not as a buy signal — track whether post-lock-up trading holds these levels.
- Compare Moore Threads' sales multiple against profitable global GPU peers before drawing conclusions about relative value.
