For information
On the question “Will China's Ministry of Commerce publish an announcement lifting or suspending its January 2026 ban on exports of dual-use items to Japan by 31 October 2027?” ARCANE puts the chance at 15%, settling by 31 Oct 2027.
Settled by: China Ministry of Commerce (MOFCOM) official announcements
A probability is ARCANE’s estimate from the evidence listed here. It is not a guarantee, and an estimate that has not been scored is not evidence of skill.
Why: three receipts
China shipped no gallium, dysprosium, terbium, or yttrium to Japan in June, extending the export freeze on key rare earth materials.
Crux Investor · 20 Jul 2026 · claim C10
Over the past 15 years, Japan has continued investing in overseas projects, boosting recycling and developing alternative technologies, but it still imports about 60% of its rare earths from China.
Asia Times · 10 Jan 2026 · claim C20
China exported about 14 tons a month of the two minerals to Japan in 2024.

What the market says
No market asks this question with this threshold, and a market with a different threshold is a different question. So this card states no edge.
For information, because no market asks this exact question, so there is no price to compare with; and the Ledger has 2 resolved calls of the 10 it needs before a score means anything.
The edge is the gap between two probabilities. It is not a prediction of profit.
What would change our mind
- Customs data shows shipments to Japan returning toward the roughly 14 tons a month that Reuters reported for 2024, or worldwide magnet exports fall as steeply as China's July magnet shipments to Japan did.
- The call resolves NO if no such announcement appears on the site by that date.
