Budapest, 19 December 2025 — 4iG Space and Defence Technologies Zrt. (4iG SDT) signed a definitive investment agreement on December 20, 2025, to become an anchor investor in the U.S.-based commercial space company Axiom Space Inc.. The transaction, valued at $100 million, establishes the first instance of a Hungarian company taking an ownership stake in a major American space infrastructure provider.
The agreement was disclosed in a capital market announcement on the Budapest Stock Exchange website. According to the filing, the partnership is designed to secure 4iG’s presence in the global commercial space sector and provide direct access to microgravity research and development programs in low Earth orbit (LEO).
The $100 million investment will be executed in two distinct tranches. The initial phase requires 4iG SDT to provide $30 million by December 31, 2025. A second payment of $70 million is scheduled for completion by March 31, 2026. The agreement becomes legally effective upon the closing of the first $30 million tranche.
“This collaboration is of historic significance for the Hungarian space industry, as it marks the first time a Hungarian company participates as an owner of a U.S. space player,” said Gellért Jászai, chairman of the board at 4iG. Jászai noted that the investment aligns with Hungary’s broader strategy to integrate into the space-based data economy.
Axiom Space Executive Chairman Dr. Kam Ghaffarian stated that 4iG SDT’s participation comes during a pivotal transition for commercial space infrastructure. Ghaffarian emphasized that the partnership will support the development of Axiom Station, intended to succeed the International Space Station (ISS) as a platform for microgravity research and orbital data processing.
Expansion of Hungarian-U.S. Space Cooperation
The investment deepens an existing operational relationship between the two entities. Axiom Space is currently the primary contractor responsible for sending the second Hungarian astronaut, Tibor Kapu, to the ISS as part of the Hungarian to Orbit (HUNOR) program.
For Axiom Space, the capital infusion supports the continued development of the world’s first commercial space station and advanced spacesuits for lunar and LEO missions. The deal also provides the Houston-based firm with a strategic European industrial partner with a background in defense and system integration.
Timeline to 2026
The primary milestone following the initial December 2025 payment will be the finalization of the $70 million tranche in March 2026. Following these financial closings, 4iG SDT expects to integrate its defense and space technology research with Axiom’s orbital data communication solutions. The partnership is expected to influence future procurement and technical collaboration within the NATO-compliant defense ecosystem.
