First Korean lock in 252 — 8.4 million tonnes, at 91%.

91% probability POSCO Holdings produces at least 8.4 million tonnes of crude steel in Q3 2026. Q2 produced 8,884 thousand tonnes at 89.5% utilisation, and the company expects profitability to keep improving quarter on quarter. Production and sales volume are different lines, and the criterion names one.

quarterly crude steel production · vs 8,884kt in Q2 2026

POSCO Holdings announced Q2 2026 consolidated results on 30 July 2026, posting sales of KRW 19.259 trillion, operating profit of KRW 819bn and net profit of KRW 761bn. Crude steel production reached 8,884 thousand tonnes with product sales volume of 8,357 thousand tonnes and a utilisation rate of 89.5%; both production and sales rose from the previous quarter. The company targets crude steel production of approximately 9 million tonnes, its maximum production level. Domestic sales rose to 55.5% of the mix from around 51% in recent years, and management expects profitability to maintain quarter-on-quarter improvement in the third quarter.

— 1 · The Locked Call

POSCO's Q3 2026 crude steel production is at least 8.4 million tonnes — P = 0.91.

We lock a binary: POSCO Holdings' reported crude steel production for Q3 2026 is 8.4 million tonnes or higher. Confidence 91%.

Q2 produced 8,884 thousand tonnes at 89.5% utilisation, against a stated maximum of roughly 9 million tonnes. Our threshold is about 5.5% below the quarter just delivered.

— 2 · Production and sales are two different numbers, 527kt apart

Q2 produced 8,884kt and sold 8,357kt. A threshold that did not say which would be arguing at resolution.

POSCO reports crude steel production and product sales volume separately, and in Q2 2026 they differed by 527 thousand tonnes — the gap between what came out of the furnaces and what left as finished product, absorbed by inventory, work in progress and yield. A threshold of 8.4 million tonnes is a comfortable claim against the first and a much tighter one against the second.

This is the same disambiguation discipline as P-233 on Max Healthcare's two revenue lines and P-249 on Siemens' two EPS measures. The criterion below names crude steel production and excludes product sales volume explicitly.

On the substance, steel production is a capacity-utilisation question rather than a demand-forecasting one over a single quarter. POSCO ran at 89.5% with roughly 9 million tonnes described as its maximum, so the floor asks only that utilisation not fall by more than about five points. Management expects profitability to keep improving into Q3, and the domestic sales mix has strengthened to 55.5% from around 51% as the Korean market stabilises after a difficult stretch since 2024.

The residual 9% is a blast furnace outage or relining, a typhoon disrupting the Pohang or Gwangyang works, or a deliberate curtailment into weak export pricing. Steel makers do cut output when margins compress, and that decision is not visible in advance.

— 3 · South Korea had no lock at all

252 predictions, and none in one of Asia's largest industrial economies.

Before this tranche we grepped the scorecard for Korean corporates and found zero. The series had covered Japan, Taiwan, China, India, Australia and New Zealand across Asia-Pacific but never Korea, despite it hosting some of the world's largest steel, memory and shipbuilding businesses. POSCO closes that with a metric that is verifiable, quarterly, and stated against the company's own maximum capacity.

Locked on 2026-09-02 — scored against POSCO's reported Q3 2026 crude steel production.

RAOSCAFF locks P-256 on 2026-09-02, before the Q3 result. Scored against crude steel production as reported by POSCO Holdings for the three months to 30 September 2026.

Binary: YES if reported Q3 2026 CRUDE STEEL PRODUCTION is 8.4 million tonnes (8,400 thousand tonnes) or greater; NO if below. CRUDE STEEL PRODUCTION specifically — NOT product sales volume, which was 527kt lower in Q2, NOT the utilisation rate, NOT consolidated sales in won, and NOT operating profit. POSCO Holdings consolidated, not the POSCO steel subsidiary in isolation if reported separately.

Q2 produced 8,884kt and sold 8,357kt. Naming which line is scored is the difference between a forecast and a dispute.
