Add to that ULA was forced to drop their prices, so Space-X doesn't really have much room to increase more. And they obviously can't increase on existing contracts.
I'm always shocked when a keyboard warrior on ycombinator thinks a company that size doesn't have a considerable workforce dedicated to figuring out what they can charge for their product... I doubt they just picked a number out of thin air. It was likely a combination of estimating how low they think their competitors go as well as where they need to be to win new business.

Falcon 9 is $62 million (and I believe that’s the expendable version, you get a discount if the mission allows for booster recovery).

The fact that these prices are publically available on their websites tells you something about the state of competition in the launch industry.
