Scope and methodology
- Included: Companies that began trading in the review window and whose prospectus places core revenue, products or strategy directly in foundation/vertical models, AI chips and critical data-center hardware, autonomous driving, robotics or industrial physical AI.
- Excluded: Legacy companies with only an “AI concept,” upstream commodity materials, vehicle brands, AI drug discovery, generic SaaS and the Beijing Stock Exchange.
- Unitree update: Unitree Robotics began trading on Aug. 19, 2026 and is now included. Its Day 1 and cumulative-return figures use unadjusted closes through Aug. 25, 2026; the rest of the atlas retains the original Aug. 17 data cutoff.
- A+H / U.S.+H: The Hong Kong listing date and return refer only to the H-share offering, not necessarily the company’s first public listing. These cases are flagged under “Core exposure.”
- Foreign investor access: “Retail access” means an overseas individual can normally buy the security through a broker that supports the relevant market. “Institutional only” means Northbound Stock Connect access is limited to institutional professional investors. “Restricted” means the A share was not on the Northbound eligible list at the Aug. 17, 2026 cutoff; QFI or qualifying onshore-account routes may still apply.
- Fundraising: Gross proceeds are estimated as the final offer price multiplied by total shares in the offering, before underwriting fees and any over-allotment exercise. A-share issue counts come from Eastmoney IPO files; Hong Kong global-offering counts come from ET Net. USD ranks use USD/CNY 6.7873 and USD/HKD 7.8473 on Aug. 17, 2026. Seyond’s De-SPAC listing had no directly comparable conventional IPO offering and is excluded from the ranking.
- Returns: The base formula is close ÷ offer price − 1. New ChiNext entries with bonus shares or cash dividends use a simple holding-value adjustment and are flagged in the table. Fees, taxes and FX are excluded. Delayed quotes and corporate-action treatment may create small differences versus live terminals. Seyond uses a De-SPAC reference-price basis.
