Impact is the average of the four parts, rounded, plus one point when Canada is directly hit on two or more channels, up to 10.
Two separate scales from 1 to 10. Strature never multiplies or merges them.
What changed
Dated, newest first
- Inola council extended its moratorium on 14 Sep 2026 and set a referendum; moratorium runs to 7 Apr 2027; project about US$4bn [6]
- The US District Court for the Northern District of Oklahoma remanded the case to Rogers County on 3 Sep 2026, finding no substantial federal question; order not appealable [5] [14]
- Justice Department asked the court to dismiss or stay the case as premature while permits are pending [7]
- Four residents sued the Energy Department seeking a pause on federal funds until a site-specific environmental review [8]
Why it matters
A UAE-led venture plans a 750,000-tonne-a-year primary aluminium smelter at Inola, Oklahoma, which would more than double US primary output. Oklahoma's Attorney General sued in June 2026 to block it and asked for a preliminary injunction in August; the case is now back in state court. No court has ordered a halt, and a town moratorium already holds construction until a local vote on 7 Apr 2027.
Why Likelihood 3 Pushes: pending injunction motion; remand to state court; tribal and local opposition; a second federal suit against DOE funding.
Why Impact 4 Threshold case a court stops site work for some months; no key price read. The effect on Canada is a gain.

How it spreads
A state or federal court orders construction or site work at the planned Inola, Oklahoma primary aluminium smelter to stop (a restraining order, a preliminary or a permanent injunction), between 25 Oct 2026 and 25 Oct 2027.
Not under wayChannels 4 on the card
- CanadaCanada supplied 56% of US aluminium imports in 2021-24 and sends 91% of its C$17.4bn aluminium exports to the US [10][11]; a halt delays a rival inside the US tariff wall, a gain for Canadian smelters (Strature's view).
- RulesA court halt would stop a federally backed plant before it is built, on a state nuisance petition.
- TradeUS primary output was 660,000 t in 2025 with 60% net import reliance [10]; a halt keeps the US reliant on imports for longer.
- InvestmentA halt would test the UAE's US industrial plans and the half-rate tariff incentive (Strature's view).

Three scenarios and their signposts
- S1
Court clears the way
The state court denies the injunction or dismisses the case; the referendum decides local permits.
- S2
Halt by court
The state court enjoins site work pending trial.
- S3
Halt by ballot
Inola voters ban smelting on 7 Apr 2027 and the fight moves to state law on the port's status; not a court halt.
| Path | Signpost |
|---|---|
| S1 | A Rogers County ruling on a preliminary injunction (the 11 Aug 2026 motion was filed in federal court before the remand) |
| S2 | An injunction hearing date set in Rogers County |
| S3 | The 7 Apr 2027 referendum result |
No probability is given for the three paths.

The other side
If the courts clear the project, the US gains its largest smelter and a firmer footing in a metal it mostly imports. If it is halted, Canadian smelters keep their share of the US market for longer (Strature's view).
