From Mexico — I’m digging into the Sunday HKEX filing that Reuters broke on Z.AI Co Ltd (2513.HK). Beijing’s ex-Zhipu just stacked about $5 billion in one weekend: roughly $2B in new Hong Kong shares plus about $3B in concurrent zero-coupon convertibles. That’s not a seed round. That’s a listed model shop topping up after a January IPO and a ~$4B July follow-on.
SCMP puts the placement near HK$15.7B for ~21.97 million H shares at HK$714 — a 10% discount to Friday’s close of HK$793, same numbers Reuters has from the filing. The stock is still roughly 7× the January listing price even after a 73% slide from the June 22 intraday high of HK$2,980. July’s placement alone raised HK$31.4B at HK$1,588 a share.
Placement + zero-coupon convertibles
The bond side is the part that made me stop scrolling. Per Reuters, Z.AI sold 20.14 billion yuan (~$3B) of zero-coupon notes due September 2027 — yuan-denominated, settled in USD, issued at 100.5% of face. Initial conversion sits at HK$892.50, a 25% premium to the HK$714 placement price. From Feb 18 2027 the company can redeem all (not part) if shares trade at or above 130% of conversion for 20 of 30 trading days. The Next Web adds the pricing detail: buyers accepted a yield between −0.5% and 0 for that conversion option.
Where does the cash go? The filing, via Reuters, is blunt: about 60% of net proceeds toward R&D on next-gen models and a fully self-training system, 15% to expansion, the rest to capitalize the structure, working capital, and general corporate uses. TNW notes the company already built a data centre without Nvidia — Chinese accelerators, expensive compute — while approaching ~$1B in sales and still giving its strongest GLM models away. I’m not romanticizing that. I’m saying the raise is aimed at models and training loops, not a Western GPU shopping list.
Timing, politics, and what’s next
TNW flags the awkward calendar: two days before pricing, the NSA, FBI, and CISA named Z.AI among six Chinese firms in an industrial-scale distillation advisory — alleged tokens from GPT-5.5 and Claude Opus. Beijing called it unfounded. Hong Kong investors still put $5B in three days later. That’s not a verdict from me; it’s the timeline the markets priced through. Separately, SCMP says Z.AI is also tutoring for a Shanghai Star Market listing (shareholder approval for up to 15 billion yuan; no application publicly accepted yet).
The Friday launch was already visible in the Reuters Sep 11 term-sheet piece; Sunday’s filing locked the close. I’m watching one number more than the ticker: that ~60% carve-out for next-gen models and a fully self-training system. If you’re tracking Chinese frontier labs from Mexico like I am, this is the raise to bookmark — not because Nvidia vanished, but because Z.AI is writing the check for models first.
