A gram of antimatter costs around $25 billion to produce.

Not even the ISS.
That price is for positrons. That's a bunch of sub-atomic particles (the anti-equivalent of electrons).

Anti-hydrogen, an actual anti-element, is estimated to be $62 trillion per gram to make. Estimated because we've never had more than a few atoms of it at any one time, nowhere near a gram.
