Nothing else come close really on a pound-for-pound basis.

A gram of antimatter costs around $25 billion to produce. Of course, there is nowhere near a gram of antimatter on earth so in real terms it costs less than other things listed here but in terms price/gram (or whatever weight measurement you want to use) nothing else comes remotely close. Not even the ISS.
