From March 9 to 13, Bitcoin spot ETFs recorded approximately $767 million in net inflows, maintaining a positive growth trend for three consecutive weeks. This further confirms the sustained interest of institutional investors in regulated Bitcoin investment channels.
In the previous week (as of March 7), Bitcoin spot ETFs had already recorded $568 million in net inflows, showing buying signs for the second consecutive week. With continued inflows during the period from March 9 to 13, U.S. spot Bitcoin ETFs have achieved net inflows for three consecutive weeks after experiencing a period of outflows earlier this year.
Three consecutive weeks of inflows.
As of the time of writing, Bitcoin's price is nearing $74,299, up approximately 1.2% from the previous day.
Three consecutive weeks of inflows indicate a shift in institutional sentiment.
Weekly ETF fund flows may only reflect short-term market positioning. However, three consecutive weeks of net inflows indicate a more lasting shift in the strategy of both institutional and retail investors allocating Bitcoin through regulated products.
This positive trend is not limited to Bitcoin alone. CoinShares' research director, James Butterfill, noted that last week, digital asset investment products overall recorded $1.06 billion in inflows, marking the third consecutive week of positive fund flows in this sector.

This $1.06 billion inflow includes Ethereum and other altcoin products, but the spot Bitcoin ETF accounts for the majority of it.
The sustainability of ETF demand impacts the short-term outlook for Bitcoin.
The continued inflows into spot ETFs directly increase the actual buying pressure for Bitcoin. Unlike futures ETFs, spot ETFs require custodians to purchase and hold real Bitcoin, which removes a portion of Bitcoin from the circulating supply.
The inflow momentum follows a period of volatility in ETF fund flows at the beginning of 2026. At that time, several weeks of net outflows raised concerns about whether the initial enthusiasm for approvals had peaked. The fund inflows in March indicate that this is not the case, but some potential factors still need to be monitored.
Fund inflows do not guarantee an immediate price increase. Large-scale redemptions could quickly reverse the flow, and macroeconomic factors, such as the Federal Reserve's monetary policy and overall risk appetite, will still independently influence Bitcoin prices regardless of ETF demand. Investors should be cautious that the relationship between inflow amounts and prices is not always linear or immediate when using fund flow data as directional signals.
This data indeed confirms that, after more than two years of being listed, regulated Bitcoin products continue to attract significant capital. The infrastructure built around spot ETFs, including custody, market-making, and authorized participant networks, seems to provide a reliable entry point for investors who prefer traditional brokerage trading channels over direct ownership of crypto assets.
Will the inflow momentum continue?
