The commodity supercycle thesis crossed from narrative into disclosed corporate reality in February 2026, when BHP's copper division generated more underlying earnings than its iron-ore business for the first time in the company's 170-year history — a structural marker that this cycle, unlike the China-urbanisation-driven 2000s boom, is being built on AI infrastructure, electrification and deglobalisation rather than a single country's industrialisation.

| Indicator | Score | Reading |
|---|---|---|
| Maturity higher is better · high confidence | 82/100 | A structural, multi-decade-scale phenomenon now in its early stages, marked by a historic disclosed earnings crossover at the world's largest miner. |
| Evidence Strength higher is better · high confidence | 80/100 | Anchored by a hard, disclosed corporate-earnings milestone and corroborated across multiple institutional research houses. |
| Commercial Proximity higher is better · high confidence | 85/100 | A historic, already-disclosed earnings shift at the industry's largest company — not a future forecast. |
| Capital & Policy Support higher is better · medium confidence | 52/100 | Demand-side government spending (electrification, grid, AI infrastructure incentives) matters more than direct producer subsidy. |
| Crowding Risk lower is better · medium confidence | 80/100 | A genuinely hot, rapidly-rotating-into trade — the sharpest capital rotation signal in the corpus this batch — though not yet at historically euphoric extremes. |
| Reflexivity Risk lower is better · medium confidence | 40/100 | Grounded in a genuine, disclosed earnings shift, though forward valuations also price in continued structural-supercycle expectations. |
