    Why Is Antimatter So Expensive?

    Antimatter is widely cited as the most expensive substance in existence. CERN and Fermilab produce only nanograms per year — and even that requires running massive particle accelerators consuming megawatts of power.

    Cost estimates

    • NASA's positron estimate: ~$25 million per milligram, or about $62.5 billion per gram.
    • CERN's antiproton estimate: Roughly $62.5 trillion per gram given current production efficiency.
    • Optimized future: If dedicated antimatter factories were ever built, costs could in theory drop to a few million dollars per gram — still hundreds of times more expensive than gold.

    For comparison: gold trades at roughly $80,000 per kilogram. Plutonium-239 costs about $4,000 per gram. Antimatter is in another universe entirely.
