Good of the Venture Capitalist reported in mid-June 2026 that helium-3 demand is projected to grow nearly 14x by 2035, driven by advances in quantum technologies, cryogenics, and fusion research. The graphic below, created in partnership with @pulsarhelium, shows projected helium-3 demand through 2035 and explores its growing role in emerging technologies.
Helium-3 is on the Rise
He-3 demand is growing fast. From 2025 to 2035, projected annual demand grows nearly 14x from 1,200 liters to 16,543 liters. For a rare but critical isotope, limited supply and rising demand make sourcing more He-3 a pressing strategic issue.
The Economic Value of Helium-3
Today, one liter of He-3 costs about $2,500. That’s roughly the same price as 700 gallons of U.S. gasoline, based on a retail average of $4 per gallon. The high price is a reflection of He-3’s rarity and specialized uses:
- Cryogenics: Critical for quantum computing to reach ultra-low temperatures below 0.01 Kelvin.
- Radiation Monitoring: Excellent at detecting neutrons released by nuclear materials, making it the gold standard for homeland border security, reactor monitoring, and scientific research.
- Medical Imaging: Enables high-contrast, radiation-free imaging of lungs.
- Fusion Energy: Ongoing research to study its theoretical use in fusion reactors as a radiation-free fuel.
Helium 3: From Theory to Opportunity
Rising demand and prices make securing new sources of He-3 more important than ever. For investors, the key question is where future supply will come from. Should we look here on Earth, or beyond, like on the Moon as well as the Earth.
