Budapest-based 4iG Space and Defence (4iG SDT) has committed to investing $100 million in US space infrastructure company Axiom Space.
In early October, 4iG SDT and Axiom Space signed a preliminary, non-binding commitment letter to pursue a $100 million equity investment in the US space infrastructure company. At the time, 4iG SDT explained that the investment would go toward developing Axiom’s contribution to the Orbital Data Center (ODC).
Axiom announced in December 2023 that it was partnering with Kepler Communications and Skyloom to develop the ODC. The system is intended to provide in-orbit cloud computing, data storage, and AI/ML (artificial intelligence and machine learning) processing for satellites in orbit, reducing reliance on ground-based infrastructure. In April 2025, the company said it aimed to launch the first two ODC nodes to low Earth orbit by the end of the year. In a year-end review published in December 2025, Axiom pushed this initial launch to early 2026.
On 19 December, 4iG announced that it had signed a definitive investment agreement with Axiom Space covering the full $100 million investment. According to the company, it will invest $30 million by 21 December, with the remaining $70 million to be invested by 31 March 2026.
“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 4iG chairman of the board Gellért Jászai. “Axiom Space is working on revolutionary technological solutions that are fundamentally transforming the commercial space sector and setting the direction for developments in the coming decades.”
While an initial announcement in October specified a particular project, the 19 December announcement was less specific about how the investment would be used. The statement simply said that the investment would allow 4iG Space and Defence to play “a key role in the space research ecosystem and the development of commercial space infrastructure in low Earth orbit (LEO).”
