Update 2026-06-02 (PST) (AI summary of creator comment): The creator is resolving this market NO. The current price is approximately $1,728/t, far below the $6,000/t threshold. Even accounting for coating premiums (10–30%), the price would not approach $6,000/t.
1,000Proposed resolution: NO Actual value: 1,728.10 USD/t
Rationale: The skeptic raises a valid concern about using uncoated spherical graphite as a proxy for coated grades, which do command premiums. However, the interpretation ladder supports using equivalent authoritative sources when the exact specification isn't available. The SMM benchmark represents the closest industry-standard reference for battery-grade spherical graphite in China. Even accounting for typical coating premiums (10-30% based on industry norms), the base price of $1,728/t would need to inc
