China's Nvidia challenger MetaX files confidentially for a Hong Kong IPO

MetaX, a Shanghai-based maker of graphics processing units built to compete with Nvidia inside Chinese data centers, confidentially filed for a listing in Hong Kong on July 24, according to people familiar with the matter. The company is targeting an initial public offering by the end of 2026 and is working with Huatai International Financial Holdings on the potential share sale. A confidential filing lets a company move through the exchange's review process without publishing a draft prospectus or timeline until close to launch — an option chip and AI firms tend to use specifically to avoid tipping off competitors during a long vetting process.

The company's founding team includes former AMD executives, and its flagship C500 chip delivers roughly 75% of the performance of Nvidia's older A100 accelerator, according to MetaX's own figures — a real but incomplete answer to the export controls that have cut Chinese buyers off from Nvidia's newest hardware. The bigger obstacle isn't raw throughput so much as software: Nvidia's CUDA ecosystem represents years of tooling and developer familiarity that MetaX has to replicate from a standing start, and the company has said IPO proceeds would go toward next-generation GPU development, software-ecosystem work, supply-chain investment, and potential acquisitions.

A Shanghai debut that set a high bar

MetaX has already tested one public market this year. The company listed on Shanghai's STAR Market on December 17, 2025, after raising roughly $600 million, and its shares surged nearly 700% on the first day of trading — lifting its valuation to about $42 billion. The business behind that valuation is still small and unprofitable: 2025 revenue came in around 1.6 billion yuan against a net loss of roughly 800 million yuan, though the first quarter of 2026 showed revenue growth of about 75% year-over-year with losses narrowing. A Hong Kong listing on top of an existing Shanghai one gives MetaX access to a second, more internationally accessible pool of capital without waiting on the mainland's typically slower and more restrictive secondary-listing rules.

Part of a bigger financing wave

MetaX isn't filing in isolation. Its Hong Kong move is part of a broader surge of capital-raising among China's AI chipmakers — competitors including Biren Technology, Iluvatar CoreX, and Moore Threads have all listed in Shanghai or Hong Kong since late 2025. The pattern traces back to Beijing's semiconductor self-reliance push, which has turned access to capital markets into policy support for domestic chipmakers racing to build viable alternatives to Nvidia while US export controls hold the newest American hardware out of reach. Each of these companies is, in effect, being financed to close a gap that policy created and policy now wants closed — worth watching for whether a priced Hong Kong listing actually follows the confidential filing, and whether MetaX's next chip narrows the gap against Nvidia's current hardware rather than its predecessor.
