Market value, source trail

market_value = traded_price (price date) / depositary_ratio x latest point-in-time SEC shares outstanding (share-count date shown; from the filing cover page, summed across share classes only where the issuer filing verifies the classes are economically equivalent (rule + evidence URL in the source text), else withheld; priced at the primary listed class, so where other classes trade at a different price the value is an approximation; restated only for issuer-verified splits after the count date); weighted-average share counts are never used

Market value price date × latest reported shares	unavailable	USD	2026-10-23	SEC cover page (10-Q 0001381197-26-000147, as of 2026-08-05): Up-C structure: the cover counts only the listed class (453,077,771). The filing states that holder owns 26.5% of the operating company (IBG, Inc. share of IBG LLC membership interests); if each listed-class share maps to one membership interest the economic share count would be about 1,709,727,438, but that mapping is not stated in the filing text, so market value is withheld
