Nikkei reports Sakana AI is preparing for an IPO, possibly as early as autumn 2027 in Japan or the U.S.; the company says it has no near-term plans
According to a November 9 report by Nikkei Asia, Japanese generative AI company Sakana AI is preparing for an initial public offering (IPO) and could list as early as autumn 2027 in Japan or the United States. The report said the listing could become the IPO of Japan’s first generative AI developer, with a valuation potentially exceeding the roughly 680 billion yen level at the time Mercari went public in 2018, placing it among the largest startup IPOs in Japanese history.
People familiar with the matter said the company has hired institutions including Goldman Sachs as IPO advisers and is considering the Tokyo Stock Exchange and the U.S. market, including Nasdaq, as listing venues, while a dual-listing possibility has not been ruled out.
Sakana AI was founded in Tokyo in 2023 by former Google researchers David Ha, Llion Jones and Ren Ito, among others, and focuses on sovereign AI and model development for the Japanese market. The company completed its Series B financing in November 2025, at a valuation of about 400 billion yen (about US$2.635 billion).
On the same day, Sakana AI posted on its official X account: Sakana AI has no near-term plans for an IPO. Our priority remains building a generational AI company that serves as Japan’s national AI champion. The Japanese portion also said that there has been no formal decision regarding an IPO at this time.

ABAB AI Insight
Sakana AI’s rapid rise is closely tied to Japan’s policy orientation toward sovereign AI. The company emphasizes localized models and enterprise deployment rather than simply taking part in the global race for larger model parameters, which has drawn attention in Japan’s financial, manufacturing and potentially defense-related scenarios. If it ultimately proceeds with a listing, its valuation reference to Mercari’s historical level reflects market expectations for pricing a domestic AI unicorn, but the specific figure will still depend on its performance at the time and market conditions.
The company clearly denied near-term IPO plans on the day of the report, which is consistent with the common practice of unlisted companies during the preparation stage. Hiring advisers and exploring markets does not amount to a formal filing or a confirmed timeline, and autumn 2027 is only the report’s “earliest possible” window. The dual-listing option also adds uncertainty to the path.
For Japan’s AI industry, if a domestic company focused on generative models successfully lists, it will provide a public-market pricing reference for the commercialization path of sovereign AI. Its previous Series B already brought in strategic investors including MUFG, showing a combination of industrial and financial capital, but the timing and scale of any listing will still depend on the company’s own business progress and regulatory approval.

The media report that the company is “preparing” and the company statement that there has been “no formal decision” can coexist; the former reflects information from people familiar with the matter, while the latter is the company’s official position.
The IPO time window, such as “earliest autumn 2027,” is a planning statement and does not mean the listing date has been determined.
