Asteroid mining won't crash the platinum market gradually — it holds until the whole supply flips off-world, then collapses

Core claims

1. Asteroid-mined PGM will not gradually deflate Earth's platinum-group-metal market — the price holds near current levels until essentially the entire supply has shifted off-world, then drops toward the (much lower) cost of space extraction. Using "a non-steady system dynamics model of the PGM market," the authors find: "the market price for PGM will eventually drop towards the much lower cost of asteroid mining, but only after the entire supply has shifted off-world." (Tier 1, arXiv:2607.06806, abstract)

2. In the transition window, the price gap between the old and new cost floor becomes pure profit for whoever can supply from space first. Per the abstract: "In the meanwhile, huge fortunes will be made. And everybody on Earth will benefit from new applications of lower-price PGM." (Tier 1, arXiv:2607.06806, abstract) — i.e. the model implies a prolonged high-margin window rather than instant price competition, because terrestrial supply doesn't undercut itself early.

3. AstroForge (the company motivating the paper) is a California asteroid-mining startup founded in 2022, targeting metallic (M-type) asteroids for PGM extraction via onboard laser-cutting and magnetic separation, with a mission (DeepSpace-2) planned for Q4 2026.

Why this was hop-worthy

The vault has essentially nothing on commodity-market economics or space-resource extraction, and the mechanism here is a nice counter-intuitive shape: naive intuition says "unlimited new supply → price crashes immediately," but a system-dynamics model of deployment lag (only one firm can supply from space at first) says the old price holds — arbitraged as founder profit — right up until the last mile of terrestrial supply is displaced, then falls off a cliff. That's a resource-transition pattern worth watching for elsewhere (e.g. any "unlimited-reserve, capacity-constrained" disruption).

Further leads

• The model itself (AstroForge_v5.mdl, an ancillary file on the arXiv submission) — not opened this run; would show the actual dynamics/assumptions rather than just the abstract's claim.
• Hotelling's rule (exhaustible-resource pricing) as the classical counterpoint this paper is implicitly arguing against — not pursued.
