Alibaba Group Holding has emerged as one of the biggest winners from China's domestic AI and semiconductor boom, with its roughly 5 per cent stake in memory-chip maker ChangXin Memory Technologies (CXMT) now worth more than 140 billion yuan — nearly 20 times the approximately 7.6 billion yuan the company invested since 2021, according to the chipmaker's prospectus and market data from Tuesday, 29 July 2026.

A semiconductor windfall

CXMT, China's largest domestic memory-chip manufacturer, made its stock market debut on Monday, 28 July 2026, with its market capitalisation closing at approximately 3.14 trillion yuan (US$464 billion) on its second trading day. Alibaba was listed as the chipmaker's largest industrial shareholder in the prospectus, underscoring the strategic depth of its early bet on domestic semiconductor capacity.

The paper gains represent a sharp contrast to one of Alibaba's most prominent investment missteps. The company acquired a controlling stake in hypermarket operator Sun Art Retail in October 2020 for HK$28 billion (US$3.6 billion), only to record more than 25 billion yuan in impairment and disposal losses before selling its entire holding to Chinese private-equity firm DCP Capital for HK$13.1 billion on 31 December 2024.

Why it matters: A deliberate strategic pivot

The divergence between these two outcomes illustrates a conscious strategic shift inside Alibaba. As the company refocuses on e-commerce and pivots toward artificial intelligence, it has moved away from controlling acquisitions designed to anchor a sprawling consumer-internet empire, instead favouring minority stakes and industrial partnerships across the AI supply chain.

In 2023, Alibaba chairman Joe Tsai publicly outlined four capital-management priorities: improving returns from operating businesses, reinvesting cash flow in future growth, monetising non-core assets, and returning capital to shareholders. The CXMT outcome and the Sun Art exit both fit neatly within that framework.

The competitive backdrop: Backing China's AI model wave

Alibaba has also been among the earliest and most active investors in China's domestic large-language-model developers. As a new cohort of AI model start-ups emerged across 2023 and 2024, the company backed Zhipu AI (known internationally as Z.ai), Moonshot AI, and MiniMax, as well as Baichuan AI and 01.AI, though the latter two have since pivoted away from foundational model development.

According to its fiscal 2024 filings, Alibaba invested approximately US$800 million in Moonshot AI — the developer behind the Kimi models — for a stake of around 36 per cent. The company subsequently joined several follow-on funding rounds, though the sizes of those additional investments were not disclosed.

What's next

With CXMT's listing now complete and Zhipu AI also reportedly seeing its valuation climb, Alibaba's minority-stake portfolio is generating returns that dwarf its earlier empire-building phase. The critical question is whether the company will begin monetising these positions — through secondary sales or structured exits — or hold them as long-term strategic anchors in China's technology supply chain.

Investors and analysts will be watching Alibaba's next quarterly filing closely for any disclosure on portfolio realisation, as well as for signals on whether it deepens its exposure to semiconductor and AI infrastructure ahead of an intensifying global chip competition cycle.
