The biggest story in space this year did not happen in orbit. On June 12, 2026, SpaceX completed the largest initial public offering in history, pricing at $135 per share and debuting at a valuation approaching $1.8 trillion. For the first time, everyday investors could buy a direct stake in the company that drove launch costs lower and reshaped the economics of space. However, most of the sector’s frontier companies remain private and out of reach for public investors.
Closing that gap is the strategy behind Planet Ventures Inc. (CSE: PXI) (OTC: PNXPF), an investment issuer focused on providing shareholders with exposure to private companies operating across multiple segments of the expanding space economy. One of those portfolio companies recently achieved a milestone: Antaris, a software-defined space infrastructure company, signed a memorandum of agreement with Transcelestial to develop and flight-test a combined surveillance and optical-communications architecture on its JANUS-2 mission in late 2026.
The implications of this announcement are twofold. First, it highlights that the next battle in space isn’t just launching satellites—it’s managing them. As the number of satellites in orbit grows, the need for efficient, software-defined systems to control and communicate with them becomes critical. Antaris’s technology aims to provide a flexible platform that can be updated in orbit, reducing the need for costly hardware replacements.
Second, Planet Ventures gives public-market investors exposure to private space companies such as Antaris, Relativity Space, and General Astronautics that are typically accessible only to venture and institutional capital. This democratization of space investing could fuel further innovation by providing a broader capital base for early-stage companies.
For investors, the takeaway is clear: the space economy is expanding beyond launch services into satellite management, in-orbit servicing, and other infrastructure. Companies like Antaris are positioning themselves to be key players in this new phase. And with vehicles like Planet Ventures, the opportunity to participate is no longer limited to the ultra-wealthy.
