A form of blitzscaling: shock and awe.

Raise an insane amount of capital, and give it away to users to gain loyalty and lock them in.

Raise so much capital so quickly that everyone else looks at it and thinks: "I'd need to raise as much capital as them to hope to compete… not worth it, I guess I'll go somewhere else."

An investing game of chicken to deter investment in alternates.

If everyone believes the entrant that was the beneficiary of kingmaking is invincible, then they are.
