In the modern satellite internet competition, Amazon's Kuiper project and SpaceX's Starlink may have similar technical approaches, but their execution paths are distinct. Both projects rely on low-Earth orbit (LEO) satellites for communication, with Kuiper planning to launch 3,236 satellites and Starlink having deployed over 6,400 satellites in orbit. Despite Kuiper's challenges with delays and launch issues, Amazon's robust infrastructure and market share may provide a sustainable competitive advantage. In contrast, Starlink has already demonstrated its financial and technical superiority, with expected revenue of $6.8 billion in 2024. Ultimately, the commercial models and long-term plans of each project will determine which one emerges victorious in this space competition.
