The Emerging Shift in Dual-Listing Strategies Between the Hong Kong and Shanghai Technology Markets

A significant trend has been observed among major mainland-listed corporations, such as the $274 billion battery manufacturer Contemporary Amperex Technology and the electronic components producer Luxshare Precision Industry, which are actively pursuing secondary listings in Hong Kong. This strategic movement is primarily driven by the desire to secure direct access to freely convertible hard currency and a broader base of international investors. However, a counter-narrative has simultaneously emerged within the financial ecosystem, suggesting that early-stage startups that have previously gone public within the offshore financial hub may now find the regulatory and investment climate of the mainland far more advantageous.

In direct opposition to the traditional “A-to-H” trajectory—whereby onshore, A-share-traded entities seek H-share flotations in Hong Kong—prominent artificial intelligence companies such as Knowledge Atlas Technology, also recognized as Zhipu, and MiniMax are charting a different course. Following highly successful initial public offering debuts earlier in the year, plans are being formulated by both artificial intelligence firms to secure secondary listings on Shanghai’s Science and Technology Innovation Board, commonly referred to as the STAR Market.

This Nasdaq-style trading venue was conceived as a critical national initiative designed to propel the technological ambitions of the country. Although the aggregate market capitalization of the STAR Market remains below $2 trillion—rendering it substantially smaller than the main exchanges in both Shanghai and Hong Kong—a listing on this specialized board is widely regarded as a major institutional achievement for burgeoning enterprises. The application processes are known to be exceptionally stringent, requiring applicants to clear substantial regulatory hurdles to demonstrate authentic, advanced technological capabilities. The strict enforcement of these standards was highlighted historically in 2021 when the computer manufacturer Lenovo was compelled to withdraw its listing application following intense regulatory scrutiny regarding its failure to meet specific criteria, including a mandated minimum research and development expenditure equivalent to five percent of total revenue.

The prestigious reputation of the STAR Market has consistently underpinned remarkably robust valuations for its listed entities. According to financial data compiled by LSEG, among the approximately fifteen companies that currently maintain dual listings across both the Shanghai and Hong Kong exchanges, the mainland-traded shares command an average forward price-to-earnings multiple of 109 times, contrasting sharply with a multiple of just 29 times observed in the offshore Hong Kong market. This valuation disparity was clearly illustrated by the trajectory of the gene-editing specialist Biocytogen Pharmaceuticals, which initiated an “H-to-A” migration in December. Following the move, the company’s mainland-listed stock experienced a valuation increase of more than double over the course of the year, whereas its corresponding H-shares registered a more modest gain of thirty-three percent.

Furthermore, a distinct preference is maintained by state-backed investment groups, including national social security funds and various local government investment vehicles, to deploy long-term capital into companies listed on the STAR Market. The availability of such stable, domestic capital pools is anticipated to be highly beneficial for enterprises like Zhipu. Concerns have been raised regarding potential equity volatility, as nearly seventy percent of the $112 billion group’s Hong Kong shares held by pre-initial public offering investors are scheduled to become eligible for public trading in July upon the expiration of a mandatory six-month lock-up period.

Regulatory alignment with this shifting market dynamic has also been signaled by senior financial authorities. It was recently affirmed by the chairman of the national securities regulatory agency that official support would be extended to qualified Hong Kong-listed corporations seeking to issue shares within the mainland market. According to reports published by domestic media outlet Cailian, approximately ten H-share enterprises have formally submitted applications for A-share flotations. While this figure remains modest when contrasted against the estimated 110 corporations currently seeking to transition from the mainland to Hong Kong, indications suggest that the prevailing directional tide of capital and corporate listings within the region may be beginning to shift.
