SpaceX To Acquire Assets From David Grain’s Investment Firm For $8 Billion

SpaceX agreed to acquire Grain Management's 800 MHz wireless spectrum portfolio for $8 billion, aiming to expand Starlink Mobile. The deal includes 14 MHz of low-band spectrum, which SpaceX plans to combine with its satellite network to challenge major carriers. Grain Management acquired the spectrum from T-Mobile in August for $2.9 billion. The transaction requires regulatory approval and may impact telecommunications equipment providers and infrastructure companies.
