Why did SpaceX just apply to launch 1 million satellites?

Why did SpaceX just apply to launch 1 million satellites? We are only a month into 2026, yet it's already clear what one of the major space stories of the year is going to be: mega-constellations, and the ongoing attempts to launch thousands of satellites into Earth's orbit. The latest development is that SpaceX has asked the US Federal Communications Commission (FCC) for permission to launch 1 million orbital data centre satellites. The previous largest filing with the FCC, also by SpaceX, was for 42,000 Starlink satellites in 2019. "This is beyond what's been proposed by any constellation," says Victoria Samson at the Secure World Foundation in the US.
