Z.AI Sold Shares at HK$1,588 in July. Now It's Taking HK$714.

TL;DR

Z.AI, the Hong Kong-listed Chinese lab formerly known as Zhipu that publishes its GLM weights openly, is raising about $5 billion, two months after raising about $4 billion. Roughly $2 billion comes from 21.97 million new shares at HK$714, a 10% discount to Friday's close. The other $3 billion is zero-coupon convertible bonds due September 2027, convertible at HK$892.50. In July the same company sold new shares at HK$1,588. On Monday the stock traded as low as HK$710, below the new placement price, and closed down 9.08% at HK$721. If you build on GLM, the short version: the lab's research budget just got refilled for years, and about $3 billion of it comes due as cash in September 2027 unless the stock gets back above HK$892.50, roughly 24% above Monday's close.

The terms

The deal launched on Friday, September 11, after the Hong Kong close, according to a term sheet reported by Reuters, and was announced over the weekend. It has two pieces, and the second one is the interesting one.

• A share placement. 21.97 million new shares at HK$714 each, a 10% discount to Friday's close of HK$793, for gross proceeds of about HK$15.68 billion ($2 billion), per CNBC.
• A convertible bond. RMB 20.14 billion (about $3 billion) of zero-coupon bonds due September 2027, denominated in yuan and settled in US dollars. The initial conversion price is HK$892.50, a 25% premium to the placement price and 12.5% above Friday's close.
• The bond's price. The term sheet set the issue price at 100% to 100.5% of face value, which works out to a yield between zero and minus 0.5%.
• The banks. China International Capital Corporation is global coordinator and joint bookrunner, with Guotai Junan Securities (Hong Kong) as the other joint bookrunner.

According to Reuters, about 60% of net proceeds will go to research and development of next-generation models and what Z.AI calls a "fully self-training system," with another 15% earmarked for expansion. TechNode lists the R&D targets as large-scale training and inference, automated training-data generation and filtering, task environments, long-range reasoning, domestic-chip adaptation, and inference optimization.

Same stock, 55% off

Z.AI listed on January 8 at HK$116.20 in a $558 million IPO, the first of China's so-called AI tigers to go public, CNBC reported at the time. The stock then ran to a 52-week high of HK$2,980. In July the company placed 19.78 million new shares at HK$1,588, raising about $4 billion.

September has been rough. The shares fell 10.02% on September 8 and 10.34% on September 10, and were down about 40% for the month by Monday's close, based on daily price data. The same week, joint advisory AA26-251A from NSA, CISA and the FBI named Z.AI among six Chinese labs accused of industrial-scale distillation of US frontier models, though markets do not publish their reasons, so treat that as context rather than cause.

Then the new placement priced at HK$714, 55% below what July's buyers paid about two months earlier. Monday's session underlined it: the stock touched HK$710, under the placement price, before closing at HK$721. July's placees are now looking at a paper loss of more than half, which is the kind of experience that makes a placement desk slow to return calls.

It was not only Z.AI. Rival MiniMax fell about 5% on Monday, CNBC reported. The shares are still roughly six times the IPO price, which tells you how far up the ride went before it turned.

Three billion of it is a one-year bet

Convertible bonds usually run for several years. This one matures in about twelve months. That turns the $3 billion tranche into cheap, short money attached to one specific wager: that Z.AI shares will be back above HK$892.50 before September 2027.

The mechanism is simple once you strip the jargon. A zero-coupon convertible pays no interest, so the holder's return is the option to swap the bond for shares at the conversion price. If the stock is well above HK$892.50, converting beats taking cash, the bond becomes equity, and Z.AI never repays the principal. If it is not, holders take their money back at maturity and Z.AI owes roughly $3 billion in cash.

Think of it as a refundable deposit on a concert that has not been booked yet. You pay up front and earn nothing while you wait. If the show happens, your deposit turns into a ticket worth more than you paid; if it does not, you get the deposit back. Paying 100.5 for a bond that returns 100 is tipping the box office for the privilege of holding the option.

Z.AI keeps an exit door of its own. The bonds are callable from February 18, 2027, if the shares trade at or above 130% of the conversion price, about HK$1,160, for 20 out of 30 trading days. That is how the company pushes holders into converting if the rally shows up early.

Runway was never the problem. Compute is.

Z.AI's first-half report puts the size of this raise in proportion. Revenue for the six months to June 30 was RMB 953.9 million, R&D was RMB 2.13 billion, and the net loss was RMB 2.07 billion, about $300 million, according to the South China Morning Post. Since January the company has raised about $558 million in its IPO, about $4 billion in July, and now about $5 billion.

So this is not a company raising to keep the lights on. A net loss is also not a cash bill: GPUs, data centers, and prepaid capacity sit on the balance sheet and reach the income statement slowly. The use-of-proceeds list is where the real spending plan shows, and nearly all of it is training and serving capacity.

A "fully self-training system" plus automated data generation and task environments reads like reinforcement-learning infrastructure, currently the most compute-hungry part of the model race. Domestic-chip adaptation is on the list too, which makes sense for a company that has been on the US Entity List since January 2025.

What this changes if you build on GLM

• The roadmap is funded. At the first-half loss rate, this raise covers years of operating losses. The risk that the open GLM line stalls for lack of money just fell sharply.
• The money got more expensive. Selling stock at less than half the July price means more dilution per dollar, and "commercialization" is right there in the use-of-proceeds language CNBC quoted. Keep an eye on the API price sheet for promotional discounts that quietly stop coming back.
• Put September 2027 on the calendar. If the stock stays below HK$892.50, about $3 billion comes due in cash. For a company sitting on this much fresh money that is not a solvency crisis, but it is a known claim on the balance sheet a year out.
• Keep the weights anyway. A vendor with a stock down about 40% in a month and a US advisory hanging over it has more moving parts than most. A local copy of the checkpoint you depend on stays useful no matter what the share price does.

The caveats

Deal terms come from the Reuters-reported term sheet and CNBC. The 100% to 100.5% issue price was a range at launch, and none of the reports checked for this post gave a final figure. Share prices are Hong Kong closes from market-data providers, not exchange filings.

The roughly $300 million loss uses the yuan-to-dollar rate implied by the wires' own conversions, about 6.7. The 60% and 15% use-of-proceeds shares are Reuters' reading of the company's disclosure. Nothing here establishes why the stock fell in September; several things happened in the same week.

Key Takeaways

• Z.AI is raising about $5 billion: roughly $2 billion in new shares at HK$714 and roughly $3 billion in zero-coupon convertible bonds due September 2027, convertible at HK$892.50.
• The placement price is 55% below the HK$1,588 Z.AI got for new shares in July, and the stock closed Monday down 9.08% at HK$721 after trading as low as HK$710.
• The bond term sheet priced it at 100% to 100.5% of face, a yield between zero and minus 0.5%, so buyers are paying for the conversion option, not for interest.
• About 60% of net proceeds goes to next-generation models and a "fully self-training system," 15% to expansion, per Reuters.
• Roughly $9.5 billion raised since the January IPO dwarfs a first-half net loss of about $300 million, so this money is about compute, not survival.
• If the shares are not back above HK$892.50 by maturity, about $3 billion comes due in cash in September 2027.
