 Interlune's milestone-gated financing structure suggests investors are managing the 'launch cost competition' risk by deferring capital deployment until technology proves out. The $23M raised vs. $500M+ contracts ratio shows investors won't fund full-scale infrastructure until extraction is demonstrated, precisely because falling launch costs create uncertainty about whether lunar He-3 can compete with terrestrial alternatives or Earth-launched supplies.

+EuCo2Al9 ADR alloy published in Nature February 2026 by Chinese researchers represents a credible terrestrial alternative to lunar He-3 for quantum computing cooling. If rare-earth-based ADR materials can reach 10-25mK operating temperatures, they eliminate the primary quantum computing demand driver for lunar He-3 extraction. This extends the paradox: falling launch costs enable lunar ISRU infrastructure, but terrestrial materials science advances (enabled by different technology curves) may obsolete the end product before infrastructure reaches commercial scale. The competition is not just launch costs versus in-space production costs, but terrestrial substitutes versus space-based originals.
