§ · Capacity-weighted companion
GPUM.MI300X.SPOT.cw · suppressed · insufficient tier coverage (all 4 surviving venues in T2)

The suggested citation refers to the headline equal-weight median fix. When citing the capacity-weighted .cw research series, qualify the series explicitly — e.g. "GPU Markets, H100 SXM spot, capacity-weighted companion, 2026-04-18" — since the .cw companion is a distinct publication and may be suppressed on days the min-sample guard triggers.
