Suiyuan’s STAR Market debut caps an eight-year run that began with a 20-slide pitch deck
Suiyuan Technology has gone public on Shanghai’s STAR Market after an eight-year buildout that investors describe as one of the longer and harder commercialization cycles in China’s AI chip sector. The company opened at RMB 410 per share, up 188.37% from its IPO price of RMB 142.18, giving it a market value of RMB 176.4 billion, the highest opening-day market capitalization among this year’s new listings so far. Founded in March 2018 by chip veterans Zhao Lidong and Zhang Yalin, Suiyuan spent years developing domestic cloud AI training chips, a segment investors viewed as more capital-intensive and technically difficult than inference chips or edge-focused products. Before listing, the company completed 10 equity financing rounds, with investors including Delta Capital, ZhenFund, Yunhe Capital, Tencent Investment and Sunshine Insurance-affiliated Sunshine Ronghui Capital. Its prospectus shows that by the end of 2025, Suiyuan had completed four generations of computing architecture and five cloud AI chips, with all five succeeding on the first tape-out. Revenue reached RMB 990 million in 2025, while net loss narrowed to RMB 1.164 billion. Still, customer concentration remains a major point of attention: Tencent was both Suiyuan’s largest customer and largest shareholder, with direct and indirect sales to Tencent accounting for 83.79% of 2025 revenue and Tencent Technology and its affiliates holding 20.26% of the company.
