 After several mixed years, the IPO market has cleared up again in 2025. According to EY, 1,259 companies went public in the previous year (+2%), with issuance volume rising significantly by 32 percent to $163.3 billion. 2026 could be even better, because there&#8217;s a whole slew of companies in the tech sector alone that are targeting IPOs or at least have such plans attributed to them. With OpenAI, Anthropic, and SpaceX, three companies are among those that could even crack the top 20 of the world&#8217;s most valuable companies with valuations of $500 billion and more.

 We provide an overview of the expected IPOs in 2026:

 MiniMax 

 Chinese AI startup MiniMax is planning its IPO in Hong Kong as early as January 9, 2026. According to reports, the offering price should be at the upper end of the price range, which would allow the company to raise around $538 million. This transaction would value MiniMax at approximately $6.5 billion and reflects sustained strong interest in generative AI across the Asian region.

 Z.ai (Zhipu AI) 

 The company known as Z.ai (internationally) or Zhipu AI is also targeting the Hong Kong stock exchange in January 2026. The IPO is expected to raise around $560 million, which would give the company a valuation of approximately $6.6 billion. Zhipu AI is considered one of the leading Chinese developers of large language models (LLMs) and competes directly with MiniMax for investor capital.

 Anthropic 

 Anthropic, maker of the popular Claude AI model, has not yet filed an official IPO application but is being traded as one of the hottest candidates for a stock market listing in the near future. Following a funding round in November 2025 by Microsoft and Nvidia, the AI developer (known for „Claude“) is reportedly now valued at an enormous $350 billion. An IPO could happen in 2026, provided market conditions remain stable. The timing window would be favorable because you currently cannot directly invest in an AI model company.

 OpenAI 

 OpenAI continues to be traded as arguably the most gigantic IPO of the coming years, with current reports suggesting a possible IPO for late 2026. The valuation has exceeded the $500 billion mark following recent funding rounds and restructuring (toward a for-profit business model), with speculation for an IPO even pointing toward $1 trillion.

 SpaceX 

 Elon Musk&#8217;s space company SpaceX is reportedly planning an IPO for 2026, with the satellite internet business Starlink serving as a key driver. Valuation expectations are astronomical, reaching speculative IPO targets of $1.5 trillion ( more on that here ). Such a move would not only make SpaceX the most valuab
