Sam Gilliam’s upcoming October 7, 2026 auction of an Untitled work sits against a secondary market where comparable pieces have realized prices from low five figures to well above six figures. Recent results include a 1977 Untitled canvas selling for $177,800 at Christie’s against an $80,000–$120,000 estimate, while smaller mixed-media and paper works from the 1970s–1990s have cleared between $4,000 and $60,000 depending on scale, medium, and provenance. Gilliam’s draped abstractions and color-field innovations continue to attract institutional and private collectors, supported by his established museum presence and steady exhibition history. Traders will watch pre-sale estimates, catalog details, and any last-minute provenance updates as the primary swing factors ahead of the sale.
