Most Expensive Materials on Earth in 2025
1. Antimatter – $62.5 Trillion per Gram
Antimatter remains the priciest substance on the planet, with estimates placing its value at around $62.5 trillion per gram. This elusive material is so costly due to the enormous energy and sophisticated technology needed to produce even tiny amounts. Its applications extend into experimental physics, potential future energy sources, and advanced propulsion systems. Currently, antimatter is mostly confined to research laboratories, given its high production cost and the challenges involved in storing it safely.
2. Actinium-225 – $29 Billion per Gram
A rare radioactive isotope, Actinium-225, commands an astronomical price of about $29 billion per gram. It plays a vital role in targeted cancer therapies, especially in treatments for aggressive cancers like leukemia and prostate cancer. Its scarcity and complex production process make it one of the most valuable materials in medicine today, with ongoing research promising even broader applications.
3. Technetium-99 – $1.9 Billion per Gram
This radioactive isotope has become essential in medical imaging procedures, particularly in nuclear medicine. Priced at approximately $1.9 billion per gram, Technetium-99’s value is driven by its widespread use and the limited, highly controlled manufacturing process. Despite its relatively small presence in the market, its importance to diagnostic medicine makes it a priceless resource.
4. Endohedral Fullerenes – $137 Million per Gram
Known as “buckyballs,” these sophisticated carbon structures encapsulate atoms within fullerenes, creating extremely stable compounds. Their uses in quantum computing and advanced electronics contribute to their high value, estimated at $137 million per gram. As technology progresses, demand for these unique molecules continues to grow.
5. Californium – $27.8 Million per Gram
A radioactive element primarily used in nuclear reactors, medical applications, and as a neutron source, Californium’s value is approximately $27.8 million per gram.
