Rocket Lab Acquires Iridium in $8 Billion Deal to Challenge SpaceX
The acquisition of Iridium Communications grants Rocket Lab access to global constellation assets and L-band spectrum, positioning the company to compete directly with SpaceX’s Starlink service in both civilian and military sectors.
Rocket Lab has announced an $8 billion acquisition of Iridium Communications, a strategic move designed to vertically integrate the launch provider’s manufacturing capabilities with Iridium’s global connectivity constellation and L-band spectrum rights. The transaction aims to establish a comprehensive satellite internet business serving both civilian and United States military markets, directly challenging SpaceX’s dominance in the sector.
The deal comes in the wake of SpaceX’s record-breaking initial public offering on the Nasdaq, which valued the company at approximately $1.77 trillion. While SpaceX’s Starlink service currently leads the satellite internet market with 10 million subscribers and $11.4 billion in annual revenue, Rocket Lab intends to leverage the combined entity’s assets to capture significant market share. Iridium generated $872 million in revenue last year, surpassing Rocket Lab’s reported figures but trailing Starlink’s performance.
Central to Rocket Lab’s strategy is the operationalisation of its new heavy-lift rocket, Neutron. The vehicle is expected to enable the faster delivery of heavier payloads to orbit, supporting the rapid expansion of the satellite internet business. This infrastructure will allow Rocket Lab to launch more satellites, both for its own constellation and for third-party customers, aiming to match the customer value proposition established by its rival.
Valuation metrics highlight the premium placed on space economy stocks despite recent sector volatility. Rocket Lab trades at a price-to-sales ratio of 54, while SpaceX trades near a ratio of 100 based on 2025 figures. These multiples stand in stark contrast to the average S&P 500 stock, which trades at a price-to-sales ratio of approximately 3.7, underscoring the high growth expectations embedded in these space-focused equities.
The broader space economy sector has experienced a dip in share prices following the SpaceX IPO, yet the industry remains critical to the global economy. By acquiring Iridium’s highly valuable L-band spectrum rights and existing constellation, Rocket Lab is positioning itself as a formidable competitor in a market where scale and speed of deployment are increasingly decisive factors.
