Axelspace Aims for June IPO Amid Mixed Investor Sentiment and Government Space Push

Tokyo-based satellite startup Axelspace plans to go public as early as June, according to sources familiar with the matter. The IPO, pending approval from the Tokyo Stock Exchange later this month, would mark the fifth listing of a Japanese space venture in two years, a notable milestone in the country’s rapidly evolving private space sector.

Key Details:

  • IPO Timing & Valuation: Axelspace’s listing could take place in June, with a potential valuation in line with peers Synspective (121B yen) and iQPS (72.5B yen), according to sources.

  • Lead Underwriter: SMBC Nikko Securities is acting as lead manager, though neither the firm nor Axelspace commented on the IPO plans.

  • Satellite Milestones: The company has launched five optical Earth observation satellites and plans to add seven more next year. It also manufactures satellites for clients like Weathernews.

  • Investor Backing: Axelspace has raised 14.3 billion yen in funding to date, with backing from Mitsui & Co. and ANA Holdings. Its Series D round was completed in 2023.

Market Context:

  • Sector Growth: Japan’s private space sector, valued at around 4 trillion yen ($27.8B), is backed by substantial government fundingincluding 600 billion yen from the Space Strategy Fundand aims to double in size by the early 2030s.

  • Investor Challenges: Despite tailwinds, most Japanese space startups remain loss-making, and investor confidence is tempered by mixed stock performance in existing space IPOs like Astroscale (down ~40%) and ispace (only recently recovered to IPO level).

  • IPO Appeal: Going public provides access to debt financing, increased hiring capacity, and new strategic partnerships, according to industry executives. However, a second wave of space IPOs may take longer due to scrutiny over profitability and market conditions for small-cap Japanese firms.

Strategic Significance:

The IPO effort signals not just Axelspace’s growth ambitions but also Japan’s strategic alignment between public defense spending and private space innovation—particularly in response to China’s rising military and tech influence. It also reflects limited private fundraising alternatives for startups in Japan compared to U.S. firms like SpaceX.

Rocket Lab Postpones Launch of Synspective’s Earth-Imaging Satellite

Rocket Lab’s scheduled launch of a radar-imaging satellite for the Japanese firm Synspective encountered an unexpected delay. The Electron rocket, intended to launch from Rocket Lab’s New Zealand facility on December 20, 2024, was grounded roughly 17 minutes before liftoff. According to the company’s statement on X (formerly Twitter), the delay was due to the need for additional analysis of sensor data. As of now, no new date for the launch has been provided.

The mission, named “Owl The Way Up,” is designed to deploy a synthetic aperture radar (SAR) satellite for Synspective. The satellite is part of Synspective’s ongoing effort to create a constellation of 30 Strix SAR satellites, which will orbit Earth in low Earth orbit. The Strix satellites are capable of providing high-resolution images of Earth’s surface, even detecting minor changes as small as a few millimeters.

The mission would mark the sixth deployment in the Strix series. Synspective, a company focused on space-based data solutions, relies on Rocket Lab for the launch of its radar-imaging satellites, with 16 dedicated launches planned to complete the Strix constellation. If successful, the upcoming Electron rocket launch will place the Strix satellite into a circular orbit approximately 574 kilometers above Earth, 54.5 minutes after takeoff.

With this mission, Rocket Lab continues to support innovative satellite technologies that contribute to Earth observation and monitoring. However, the postponement serves as a reminder of the complexities involved in space missions, where data integrity and review are critical to ensuring the success of the operation. As the revised launch date remains unclear, both Synspective and Rocket Lab are likely working to ensure all aspects are thoroughly checked before proceeding.
