Pretty much all the private investment in hyperloops is to get to the point of selling it for public infrastructure projects (it was originally proposed as an alternative specifically to California High Speed Rail), so, while the answer is mostly “no” in the strict present sense of “is”, it's also “yes” in the sense of the intended goal of the projects.
frankly (as an east-coaster) I would be happy just to see the existing rail lines be price competitive with airlines. I greatly prefer traveling by train, and I would be willing to accept a longer transit time if it were not both slower and more expensive.
This is infrastructure, if this ever is going to be a business it's going to be public money, it's not like someone builts a hyperloop on their cow farm.

Two, public money is private money. That's what taxes are.
