Summary
US spot Bitcoin ETFs posted a net inflow of $131.32 million on May 13, 2026, according to Bitget data, signaling renewed institutional demand following a period of significant redemptions. This inflow reverses the previous trading session's substantial $635 million net outflow, indicating potential stabilization in investor sentiment toward digital asset exposure through traditional equity vehicles.
BlackRock's IBIT (iShares Bitcoin Trust) dominated the inflow activity, recording $135 million in single-day net inflows—the largest among competing spot Bitcoin ETF products. This concentration underscores BlackRock's dominant market position in the Bitcoin ETF space and suggests institutional capital is flowing preferentially toward the largest and most liquid vehicles.
The May 13 inflow occurs within a volatile broader context. Prior to the recent stabilization, spot Bitcoin ETFs had experienced a seven-day consecutive outflow period that drained approximately $1.12 billion from the sector. This recent inflow represents an important inflection point, though the magnitude ($131.32 million) suggests measured rather than aggressive institutional re-entry. Current total assets under management across US spot Bitcoin ETFs approach $87 billion, demonstrating that despite recent flow volatility, the structural adoption of Bitcoin exposure through regulated ETF products remains materially significant for institutional portfolios.
The flow dynamics reflect the ongoing bifurcation in institutional Bitcoin positioning, with concentrated flows through dominant platforms like IBIT offsetting redemptions elsewhere in the competitive ETF landscape. For hedge funds and family offices, this pattern suggests that ETF selection and timing remain critical variables in managing Bitcoin exposure within traditional investment frameworks.
