BCB26 · 2026 Bowman Chrome Chase Index

PER SET — BCB26 is 2026 Bowman Chrome only. May's paper Bowman, Sapphire and Draft each get their own ticker; nothing is mixed across sets. The Bangers board is the cross-set 1st Bowman instrument. · TABS — BASE (Chrome Prospects) and AUTOS (Chrome Prospect Autographs, 15% single-card cap) are separate baskets; PARALLELS activates when parallel asks are verifiable. · BASIS — ask basis, labeled on every row: a verified ask is what a seller is asking on a live, engine-verified listing — it is not a sale and is never called one. When SCP sold coverage reaches ≥60% of basket value the index restates to hammer basis through a logged divisor adjustment; the level is identical before and after. Asks and solds are never blended. · ACTIVATION — first re-mark with verified asks covering ≥60% of chase-basket value: divisor = basket value ÷ 100, inception = that date, level 100.00. · WEIGHT — price ÷ basket value within a tab; unpriced cards carry zero weight and enter via logged divisor adjustments so inclusion never moves the level. · 1ST BOWMAN — the 1st logo is on every Bowman card a player gets in his debut year (paper, Chrome, Sapphire, parallels). No checklist marks it per card, so the tag appears only on the Bangers board names and players the sources explicitly named as 2026 1st Bowmans. Untagged = unknown. · ★ — Track in your Vault (free, no account): Hunting or I Own It. No price is seeded pre-activation. · FULL METHODOLOGY — solds vs asks vs engine marks: /how-prices-work. · NO CALLS — an index is a measurement, not a recommendation. The board makes calls and is graded in public on the Scorecard; this page does not.
