Chinese AI drug design startup Metis TechBio raises $270m in HK IPO

METiS TechBio, an AI drug design startup, raised HK$2.11 billion, or US$269.5 million, in its Hong Kong IPO.

Its shares jumped on debut on May 13 as demand for AI-related stocks remained strong.

The company sold 201.23 million shares at HK$10.50 (US$1.3) each, becoming the third AI drug developer to list in Hong Kong after XtalPi in June 2024 and Insilico Medicine in December 2025.

An exchange filing showed 18 cornerstone investors subscribed a combined US$148 million and agreed to a six-month lock-up.

The investors included BlackRock, UBS Asset Management Singapore, Mirae Asset Securities, HHLR Advisors, and China Asset Management.

🧠 Food for thought

Implications, context, and why it matters.

Metis is more of a delivery platform than a drug discovery firm

  • The company’s technology centers on getting drugs to the right cells through its AI-driven “NanoForge” platform, which builds tiny carriers for use inside the body 1.
  • NanoForge uses a library of more than 10 million lipid structures (fat-like molecules often used in drug delivery) plus AI models with high-throughput lab screening (an automated way to test many options quickly) to build nanoscale delivery vehicles 2.
  • Metis says the system can cut average development time for targeted formulations, versions of drugs made for specific tissues or uses, to two to three months 1.
  • That approach supports two lines of business, licensing the company’s own drug candidates and working with more than 30 pharmaceutical and biotechnology partners worldwide 1.

The IPO’s cornerstone demand suggests investor interest in tech-enabled R&D

  • The US$148 million cornerstone tranche suggests investors see promise in the company’s AI-enabled nanodelivery platform, though calling it a record depends on the group of offerings used for comparison 3.
  • The cornerstone group includes BlackRock and UBS Asset Management, plus Deerfield, a healthcare-focused investment firm 3. It also includes Hillhouse and IDG 3.
  • The business model also looks more profitable, with gross margin rising from 59.8% in 2023 to 98.2% in 2025 1.
  • The listing may give other companies a path to attract funding for work that mixes AI with hands-on research and development infrastructure to take on hard biology problems.
