The GPU IPO That Refuses to Stop Raising: Biren Weighs Another $1 Billion Share Sale

Shanghai Biren Technology, the GPU designer that became Hong Kong’s first listed pure-play AI chip stock this January, is weighing yet another share sale — its third major capital raise of 2026. According to Bloomberg News, the company is sounding out interest from potential investors for an offering of roughly US$1 billion, with banks in the early stages of gauging demand.

The timing is eye-catching. Biren already pulled in about US$900 million from a share placement in July, and it agreed at the time not to sell additional stock for 90 days — a lockup that expires in early October. Depending on market conditions, the new offering could launch shortly after that window closes. Details such as the final size and structure haven’t been finalized, and Biren may yet decide not to proceed at all. The company did not respond to requests for comment.

Why Biren keeps going back to the well

Biren is one of the “GPU four little dragons” — the cohort of Chinese GPU developers championed by Beijing as domestic alternatives to Nvidia. It listed on the Hong Kong Stock Exchange on January 2, 2026, pricing its IPO at HK$19.60 per share under Chapter 18C for specialist technology companies, raising approximately HK$5.58 billion (about US$717 million) in what became the largest 18C listing to date. The stock opened at HK$35.70 and jumped more than 70% on debut, at one point reaching a closing high of HK$68 in June.

The fundamental story investors are buying is rapid growth. Biren’s 2025 revenue reached CNY 1.035 billion (about US$145 million), up 207% year-over-year, and its preliminary first-half 2026 results are even more dramatic: revenue of CNY 1.15–1.30 billion, up roughly 1,852–2,107% from CNY 58.9 million a year earlier. Tom’s Hardware reports the company posted around 2,000% year-over-year shipment growth in the first half of 2026, with its BR100 HPC GPU claimed to outperform prior domestic production by 30–40%.

But hypergrowth in semiconductors is expensive. Biren’s book net loss for 2025 was CNY 16.49 billion — though that figure is dominated by non-cash accounting changes in the fair value of redeemable preferred shares from before the IPO, with the adjusted operating loss far smaller (the H1 2026 forecast loss is CNY 320–400 million). Designing and taping out competitive GPGPUs, building a CUDA-class software stack, and buying foundry capacity at scale all consume capital faster than a few hundred million dollars of quarterly revenue can replenish it. Hence: IPO in January, placement in July, and possibly another billion dollars in October.

The market isn’t cheering

Investors have begun pushing back on the sheer volume of paper hitting the market. Following the Bloomberg report, Biren erased an 8.2% intraday gain and closed down about 1% in Hong Kong trading. The stock has retreated to roughly half its June peak, leaving the company with a market capitalization of about HK$86 billion (US$11 billion).

The broader context is worse. The Hang Seng Tech Index is down 22% this year, weighed down by exactly this dynamic: Chinese AI and chip firms racing to raise capital while markets worry about dilution and eventual compute oversupply. Zhipu (Z.AI) announced a US$5 billion stock-and-convertible-bond sale on Sunday — following a US$4 billion deal in July — and its shares have fallen 16% this week. MiniMax, which also raised in July, is down 13% this week. Even Alibaba’s HK$80 billion placement last month, still Hong Kong’s biggest-ever follow-on, sent its shares down by the most in more than a year the following day.

The China chip calculus

Why raise into weakness? Because the strategic clock is ticking. Since Washington tightened export controls, Nvidia’s most advanced accelerators are effectively unavailable to Chinese buyers, and Beijing has responded by rallying capital, procurement, and policy behind domestic alternatives. A company like Biren faces a land-grab moment: every hyperscaler, “intelligence computing center,” and state-backed AI fund in China is qualifying domestic GPUs right now, and the suppliers that scale fastest — in software maturity as much as silicon — will lock in the design wins that define the next decade.

Access to public markets has become a weapon in that race. A Hong Kong listing lets Biren tap global institutional liquidity repeatedly and quickly, something its unlisted peers (Moore Threads, MetaX, and others still queuing for IPOs) cannot match. If the October window opens, management seems inclined to take the billion dollars while it’s on offer — dilution complaints are cheaper than ceding the domestic market to better-funded rivals.

What to watch

Three signals will determine whether this raise is savvy or a top-tick: first, whether the placement prices near current levels or requires a meaningful discount (July’s placement went at HK$46.20; the stock now trades far below); second, whether H1 2026’s ~19x revenue growth continues into H2 as BR100-class shipments scale; and third, whether the post-lockup flood of Chinese AI equity — Zhipu, MiniMax, Biren, and rumored deals behind them — exhausts demand or finds a new baseline of buyers who simply want exposure to China’s sovereign AI buildout.

Biren’s deliberations are ongoing, and no deal is guaranteed. But the pattern is now unmistakable: China’s chip champions have discovered that the fastest way to fund the race against Nvidia — and against each other — is to sell stock, early and often.
