Alibaba Files to List Chip Unit T-Head, Says Spin-Off Is Small for the Group
Alibaba Group Holding has filed to list its data-center chip unit in Hong Kong — a formal capital-markets step it ultimately did not take for its cloud business or its logistics arm — while telling the exchange that this spin-off should be too small to matter much to the parent.
A filing dated November 10 said the Hong Kong exchange has confirmed that Alibaba may proceed with a separate Main Board listing of T-Head, its wholly owned chip subsidiary, and that T-Head submitted a confidential application on September 11, 2026. The notice leaves out the figures investors would need to value the unit: how much a deal might raise, when it could list, or how large a stake Alibaba would still hold. The company said T-Head is expected to remain a subsidiary.
That is a more modest presentation than Alibaba has given the chip business in its own operating updates. On the company’s March 19, 2026, earnings call, Chief Executive Eddie Yongming Wu said that as of February, T-Head had shipped 470,000 chips, that more than 60% of them were being used by external commercial customers, and that annualized revenue had reached “the 10 billion RMB level.” He called T-Head “crucial to Alibaba’s AI strategy” because it helps guarantee the supply of computing power in a tight market, and because it can be co-designed with Alibaba Cloud and the Qwen models. He also said, in the same answer, that domestic chips “still lag behind their foreign counterparts in manufacturing process nodes and overall performance.” Asked about listing rumors, Wu said Alibaba did not rule out an IPO for T-Head, but had “no specific timetable.”
The product cadence since then has been public, even if the IPO timetable was not. In May, T-Head unveiled the Zhenwu M890, which Alibaba said delivered three times the performance of the earlier Zhenwu 810E, with 144 gigabytes of memory and 800 gigabytes per second of inter-chip bandwidth. The company said more than 560,000 Zhenwu chips had been shipped by then, and that more than 400 external customers had deployed them. In September, at the Apsara Conference — days after the confidential listing application was filed — T-Head introduced the Zhenwu V900, which Alibaba said would again triple the performance of the M890, with 216 gigabytes of memory and 1,200 gigabytes per second of inter-chip bandwidth. Mass production and commercial release were scheduled for the first quarter of 2027. Customer numbers were raised to more than 650.
None of those operating figures appear in the November filing, which describes T-Head only as “a leading provider of full-stack data center chips which enable system-level compute solutions in China.” The document also does not break out the unit’s revenue, profit, or shipments. Unofficial estimates of how much a listing might raise have circulated in later media reports; they are not in the announcement and have not been confirmed by the company.
Alibaba’s recent history is why a filing should not be read as a completed deal. In November 2023, it shelved a planned spin-off of its cloud unit, citing uncertainty around U.S. restrictions on advanced AI chips; the Hong Kong shares fell 10% the next day, erasing about $20 billion in market value, according to Reuters. In March 2024, it withdrew the Hong Kong IPO application of logistics subsidiary Cainiao and offered to buy out minority shareholders for up to $3.75 billion. Those businesses were pulled back because, in Alibaba’s telling, they were too tightly bound to the group’s core strategy to be separated. T-Head is being taken in the opposite direction, and with a different official emphasis: the company told the exchange that it expects the highest applicable percentage ratios under Hong Kong listing rules to be less than 5%, so the spin-off would not be a discloseable transaction, and that “the Proposed Spin-off is insignificant to the Company and its Shareholders with reference to the Company’s total assets, revenue and net income.”
That language was part of Alibaba’s successful request for a waiver from Practice Note 15, which ordinarily expects a listed company to give existing shareholders an assured entitlement to shares in a spun-off entity. Alibaba also argued that arranging such an entitlement would be unduly burdensome under U.S. securities laws and impractical under PRC rules. If the transaction proceeds, it would be a global offering of T-Head H-shares — a Hong Kong public offering plus a placing to institutional and professional investors — and would not, the company said, affect Alibaba’s dual primary listings in Hong Kong and New York.
The chip unit would be arriving in a market that is already filling up. Baidu said in January that its AI chip unit, Kunlunxin, had confidentially filed for a Hong Kong listing. Other domestic designers have been raising capital or planning additional listings of their own. A T-Head IPO would give the business a currency to hire, buy, and invest alongside those peers. It would not, on Alibaba’s telling, change who controls it.
ChinaBiz Insider reported in January that T-Head was said to be preparing an IPO, and that a JPMorgan note treated the talk as a sentiment catalyst rather than a 2026 transaction. The November filing settles one part of that debate: a confidential Form A1 has been submitted, in 2026. It leaves Wu’s caution about timing intact. The application is official. A priced deal is not, and Alibaba has already shown, twice, that it can walk a spin-off back after the paperwork has started.
The remaining conditions are unchanged. The spin-off still needs approval from the Stock Exchange’s Listing Committee, a filing with the China Securities Regulatory Commission, and final decisions by Alibaba and T-Head. “There is no assurance that the Proposed Spin-off will take place or as to when it may take place,” the company said.
