Bitcoin ETF Flows and Market Impact (2026 Outlook)

U.S. spot Bitcoin ETFs have significantly reshaped the BTC market by early-mid 2026, amassing approximately $58-59 billion in cumulative net inflows and $102 billion in AUM. BlackRock's IBIT dominates both inflows and AUM, establishing a clear hierarchy among issuers. This institutional adoption has deeply influenced spot liquidity, concentrating BTC holdings off-exchange while simultaneously improving trading conditions for institutional participants and making ETF flows a primary driver of near-term market dynamics.
