Hong Kong's capital market is witnessing a fierce liquidity rush driven by semiconductor and AI hardware plays in late June 2026. Four major tech companies completing their initial public offerings or share placements this week are targeting a combined capital raise of more than HKD 14 billion. The wave is heavily anchored by retail frenzies and institutional bets on AI optical modules, precision manufacturing, and robotics, according to market data and people familiar with the matter.

Haiguang Xinzheng (1191.HK)

Positioned squarely in the AI optical module boom, silicon photonics provider Haiguang Xinzheng listed on June 29, 2026, raising approximately HKD 1.53 billion. The firm's retail tranche recorded a staggering 1,296.89 times oversubscription. In pre-market gray trading, shares surged over 80% above the issue price, according to trading platform data. The company is backed by tech giants Alibaba Group and Xiaomi, as well as Suzhou state capital.

SG Micro (3661.HK)

SG Micro, ranked first among China's domestic analog integrated circuit makers by 2025 revenue, debuted its H-shares on June 26, 2026, raising a net HKD 4.5 billion. Offering a portfolio of over 7,200 signal chain and power management chips, the retail offering was 250.7 times oversubscribed. Shares jumped more than 47% on their first day of trading. The dual-listing drew 23 cornerstone investors, including GIC and Hillhouse.

Lingyi iTech (1688.HK)

Ranking first globally in the high-precision functional parts market for AI terminal devices by 2025 revenue, Lingyi iTech also listed on June 26, 2026. The offering raised a total of HKD 8.26 billion as the company expands across consumer electronics, new energy vehicles, and robotics servers.

Laifu Harmonic (3952.HK)

Expected to list on June 30, 2026, under Chapter 18C, Laifu Harmonic is one of the only two domestic manufacturers to achieve mass production of harmonic reducers for humanoid robots.

The firm's products deliver ±15 arc-seconds positioning accuracy and a lifespan exceeding 10,000 hours.

OmniVision Group (501.HK)

Beyond the IPO frenzy, established semiconductor players are accelerating capital moves. OmniVision Group proposed adopting an H-share incentive plan on June 24, 2026. In mid-June, industry reports indicated the firm invested in a chip company linked to Nio. Management recently told investors it is strictly executing its share repurchase program.

Black Sesame Technologies (2533.HK)

As a provider of smart vehicle chips and autonomous driving solutions, Black Sesame Technologies remains a critical player in the automotive silicon space, maintaining its strategic footprint as capital rotates heavily into the broader hardware and AI sectors.

The aggressive influx of institutional and retail funds underscores a significant liquidity recovery in Hong Kong's tech hardware sector. Market observers are now targeting these newly listed players' upcoming earnings reports as the next major catalyst.
