AI chipmaker SigmaStar eyes up to $300 million in a potential Hong Kong float this year

What SigmaStar is lining up

SigmaStar Technology is considering a Hong Kong listing that could bring in up to $300 million as soon as this year, according to people familiar with the plan who asked not to be named because the details are not public. The company has begun meetings with potential investors.

It is working with China International Capital Corp. and China Securities International, per a filing with Hong Kong's stock exchange. A company representative did not return a request for comment right away.

The business under the hood

Established in 2017, SigmaStar develops semiconductors for security gear, action and sports cameras, self driving vehicles and smart home devices, as well as other applications, according to its website. Taiwan's MediaTek once held a 16.5% stake through a subsidiary but exited the holding in 2021.

Investors have noticed. The company's shares have climbed 67% this year in Shenzhen.

Where this fits in the market

Chinese technology issuers, including players in the AI supply chain, have pressed ahead through choppy trading as skepticism around the tech built. That helped share sales pick up in Hong Kong after listings slowed from a blockbuster summer pace.

To date this year, companies listing in Hong Kong have pulled in $52.2 billion, approaching the 2010 peak of $57.8 billion, Bloomberg data show. Chinese chipmakers and other AI supply chain firms have been central to that momentum, supported by Beijing's push to cultivate national champions and strengthen self reliance. One highlight was Shanghai Biren Technology Co.; upon its January debut, its stock jumped more than 70%. Another example is Shenzhen Longsys Electronics Co., which, after upsizing the deal, brought in $903 million.

Why investors should care

If SigmaStar comes to market, it would slot into a fundraising window that has reopened for Chinese tech names. For your portfolio, the takeaway is simple: Hong Kong's pipeline still has scale deals tied to China's semiconductor and AI ecosystems, and policy tailwinds remain a key driver.
