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. Yet 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 significant milestone. Antaris, a software-defined space infrastructure company backed by Planet Ventures, 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.
This partnership underscores a broader shift in the space industry: the next frontier is not just launching satellites but managing them in orbit. Antaris’s software-defined approach allows satellites to be reconfigured in space, reducing the need for dedicated hardware and enabling more flexible missions. By integrating surveillance and optical communications, the JANUS-2 mission aims to demonstrate how satellites can both observe the Earth and transmit data at high speeds using laser links.
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. Relativity Space is developing 3D-printed rockets, while General Astronautics focuses on in-space propulsion and orbital services. These companies represent different segments of the space economy, from launch to satellite operations to in-orbit services.
The global space economy is projected to grow to over $1 trillion by 2040, according to estimates from Morgan Stanley and other analysts. While launch providers like SpaceX have captured much of the attention, the majority of growth is expected to come from satellite applications, including communications, Earth observation, and space-based services. These segments are dominated by private companies that have not yet gone public.
Planet Ventures aims to bridge this gap by pooling capital from public investors and deploying it into a diversified portfolio of private space companies. The company’s investment thesis is that as the space economy matures, these private firms will generate significant returns, and public investors should have access to them before they list on public exchanges.
The Antaris-Transcelestial agreement is a concrete example of how Planet Ventures’ portfolio companies are advancing the state of the art. Transcelestial is developing high-speed optical communication terminals for space, which could enable data rates orders of magnitude higher than traditional radio frequency links. Combined with Antaris’s software-defined satellite platform, the JANUS-2 mission could pave the way for more capable and flexible satellite constellations.
For investors looking to participate in the next wave of space innovation, Planet Ventures offers a unique opportunity. While SpaceX’s IPO was a landmark event, the real action in space may be happening off the public markets. Planet Ventures is positioning itself as a gateway for those who want to invest in the private companies that are building the infrastructure for the space economy of the future.
