Record Weekly Outflow
According to SoSoValue data, Bitcoin spot ETFs experienced a net outflow of $1.79 billion during the trading week from June 22 to June 26 (EST), marking the third highest weekly outflow in history. This sharp capital withdrawal reflects a cautious short-term market sentiment. Prior records include a ~$2.2 billion outflow in December 2025 and a ~$2.0 billion outflow in November 2025, placing the current figure in third place.
Divergent Flows Among Major ETFs
The largest weekly outflow came from BlackRock's IBIT, which shed $1.303 billion net. Despite this massive single-week drain, IBIT's cumulative net inflow since launch remains a robust $60.77 billion, underscoring its sustained long-term appeal. Fidelity's FBTC followed with a $315 million net outflow, bringing its cumulative total to $10.14 billion.
In contrast, Grayscale's Bitcoin Mini Trust BTC bucked the trend with a net inflow of $71.7 million for the week, lifting its cumulative net inflow to $2.38 billion. This divergence suggests that some investors are rotating into lower-cost mini trust products even as broader ETF flows turn negative, highlighting a shift in fee-sensitive capital allocation.
Total Market Value and Cumulative Inflows
As of press time, the total net asset value of Bitcoin spot ETFs stood at approximately $72.82 billion, with an ETF-to-Bitcoin market cap ratio of 6.08%. Despite consecutive weeks of net outflows, the cumulative net inflow since the ETFs' inception remains high at $51.61 billion, indicating that the overall capital base remains significant. Market participants are watching closely to see whether this outflow trend persists in the coming week and how macroeconomic factors may influence crypto market sentiment.
