ETF Cost Basis
The weighted-average purchase price across an ETF's outstanding shares, calculated from the prices at which the underlying Bitcoin was acquired. For Bitcoin spot ETFs, the aggregate cost basis across the entire issuer cohort is a single number that tells you whether the marginal ETF holder is in profit or loss. When spot trades above the aggregate cost basis, ETF flows tend to be sticky. When spot trades below, redemption risk increases.

Bitcoin ETF Flows and Market Structure
The January 2024 launch of US spot Bitcoin ETFs converted Bitcoin from a retail-led market into one where institutional flows, accumulation vehicles, and derivatives positioning set the price. TBL reads the post-ETF tape through five signals: flows by issuer, aggregate ETF cost basis versus spot, supply versus demand on a 90-day basis, the Coinbase premium, and the trend-versus-valuation quadrant.
