All 627 trading days since January 2024
Bitcoin ETF flow history tracks the daily net inflows and outflows across all 11 US spot Bitcoin ETFs approved by the SEC in January 2024. When institutional investors buy shares in funds like BlackRock's IBIT or Fidelity's FBTC, the ETF issuers must purchase actual Bitcoin on the open market to back those shares — creating direct and measurable buying pressure on Bitcoin's spot price. This is why large ETF inflow days frequently coincide with Bitcoin price increases, while outflow periods (led historically by Grayscale's GBTC following its fee-driven exodus) have often preceded short-term price weakness. Tracking this data day by day reveals the true scale of institutional Bitcoin adoption. This complete bitcoin etf flow history table shows every trading day since launch, giving you the full picture of how institutional demand has evolved over time.
Bitcoin ETF flows refer to the daily net movement of money into or out of spot Bitcoin exchange-traded funds. A positive flow (inflow) means investors bought more ETF shares than they sold that day, requiring the fund to purchase additional Bitcoin. A negative flow (outflow) means more shares were redeemed than created, requiring the fund to sell Bitcoin. These flows are reported in US dollars and are one of the most closely watched metrics for gauging institutional Bitcoin demand.
Every dollar of net inflow into a spot Bitcoin ETF requires the fund's authorised participant to buy actual Bitcoin on the open market. Unlike futures-based products, spot ETFs hold real BTC. When institutional demand is strong and hundreds of millions of dollars flow in on a single day, that represents genuine spot market buying that reduces the available supply and pushes the price higher. This is why the launch of US spot Bitcoin ETFs in January 2024 was considered a structural shift for Bitcoin's price discovery.
Negative ETF flows (outflows) mean that more investors redeemed shares than bought them on a given day. This forces the ETF to sell Bitcoin to return cash to those investors, creating selling pressure in the spot market. Persistent outflows — as seen with Grayscale's GBTC in early 2024 due to its higher fee structure and legacy holders taking profits — can act as a significant headwind on Bitcoin's price. However, outflows from one ETF are often offset by inflows into lower-fee competitors like IBIT and FBTC.
BlackRock's iShares Bitcoin Trust (IBIT) has accumulated the most inflows of any spot Bitcoin ETF since launch, surpassing $60 billion in cumulative net inflows and becoming the fastest ETF of any asset class to reach $50 billion in AUM. Fidelity's Wise Origin Bitcoin Fund (FBTC) ranks second. Together, IBIT and FBTC account for the majority of all positive flow days in this bitcoin etf flow history table.
