Bitcoin ETFs Approach $1 Billion in Weekly Inflows, Marking Strongest Period Since Mid-January

9

Spot Bitcoin ETFs experienced nearly $1 billion in weekly net inflows last week, marking their most robust seven-day period since mid-January, according to CoinGlass flow data.

BlackRock’s IBIT accounted for $612 million of that total, highlighting the institutional focus on this leading fund. The primary question now is whether this flow momentum will provide lasting price support or if tactical resistance will once again limit the rally.

Year-to-date inflows into Bitcoin products have turned positive for the first time since January, a milestone noted by Bloomberg ETF analyst Eric Balchunas as indicative of “extraordinary institutional acceptance” of Bitcoin as an asset class.

The total net assets across all U.S. spot Bitcoin ETFs exceeded $101 billion by the close of trading on Friday, with daily trading volumes nearing $4.8 billion.

Key Takeaways:

  • Weekly inflows: Nearly $1 billion – highest since mid-January
  • IBIT dominance: BlackRock secured $612 million of total inflows
  • Total net assets: Exceeded $101 billion by week’s end
  • YTD flows: Positive for the first time since January according to Bloomberg’s Balchunas
  • Global share: U.S. institutions captured 96.4% of $1.1 billion in global crypto product inflows
  • ETFs: $275 million net inflows; XRP ETFs gained $11.75 million; Solana experienced a loss of $5.6 million

What $1 Billion in Weekly Bitcoin ETFs Inflows Actually Signals

The weekly flow analysis indicates a Friday-heavy trend: $663.9 million arrived on Friday alone, accounting for approximately two-thirds of the total, with Tuesday contributing $411.5 million and Wednesday adding $186 million. Thursday saw only $26 million, while Monday recorded a $291 million outflow. This fluctuation in daily flows suggests opportunistic accumulation rather than a consistent institutional inflow.

IBIT’s $612 million weekly influx elevated its market capitalization to $159.22 billion, positioning it among the largest ETFs globally by assets. Fidelity’s FBTC also made a significant contribution to inflows, while Grayscale’s GBTC continued to decline – a division that reflects ongoing confidence in lower-fee products and persistent exit pressure from legacy investors.

U.S. institutions captured 96.4% of global crypto product inflows last week, absorbing $1.06 billion of a total $1.1 billion globally. This concentration is significant: it indicates that Bitcoin demand is increasingly centralized within regulated U.S. vehicles, making ETF flow data a reliable leading indicator for the near-term direction of prices.

If weekly inflows remain above $750 million, BTC’s support level around current prices will strengthen considerably. Conversely, if inflows revert to the $200–$300 million range observed during January’s plateau, the demand will diminish rapidly.

Ethereum spot ETFs attracted $275 million net last week, XRP ETFs gained $11.75 million, and Solana lost $5.6 million; this reflects selective altcoin rotation rather than a widespread risk-on movement.
