Bitcoin ETF Buying Extends to $3.8 Billion as XRP Fund Flows Cool

Wall Street’s Bitcoin demand did not disappear when the price wobbled. It got stronger.

United States spot Bitcoin exchange-traded funds pulled in nearly $1 billion during the latest week, extending their strongest three-week stretch of 2026 to roughly $3.8 billion.

Cointelegraph found that the latest weekly intake rose about 7% from the prior week even as Bitcoin briefly slipped below $79,000. Total net assets across the spot Bitcoin funds stood near $101.3 billion on Friday after reaching $103.3 billion one day earlier.

Cumulative net inflows reached approximately $55.6 billion. The rebound is substantial, but it has not fully erased the heavy withdrawals from earlier in 2026, leaving year-to-date flows roughly $1 billion negative.

The timing is what makes the three-week figure important. Buyers continued allocating through a major macroeconomic repricing and another round of Bitcoin volatility instead of waiting for a clean breakout.

Daily fund flows had recently swung negative, underscoring how quickly institutional positioning can change around economic data and Bitcoin’s price.

Farside Investors tracks the daily issuer-level numbers behind that volatile headline. The latest sequence ended constructively: spot Bitcoin ETFs added $174.6 million on Friday after taking in nearly $731 million on Thursday.

BlackRock’s IBIT accounted for $117.4 million of Friday’s total, or about two-thirds of the net inflow. That concentration shows the largest fund is still doing much of the heavy lifting, but the broader weekly total matters more than any single issuer or session.

One strong day can be a tactical trade. Three consecutive weeks totaling $3.8 billion looks more like a renewed allocation trend, especially when it survives a brief drop below a major Bitcoin price level.

The newest marginal dollar also favored Bitcoin over the other leading crypto funds.

SoSoValue data showed weekly spot Ether ETF inflows falling to about $218.4 million from $824.4 million. Spot XRP ETF inflows dropped even more sharply on a percentage basis, declining to roughly $19 million from $110.5 million.

Those weekly slowdowns do not mean the Ether or XRP fund stories have broken. Both remain positive for the year, and their cumulative demand provides a much broader picture than one week of flows.

The comparison instead shows where fresh institutional appetite was strongest during this particular stretch. Bitcoin absorbed close to $1 billion while the pace cooled materially in the two other major spot-crypto ETF groups.

The cumulative XRP ETF picture remains stronger than the latest weekly slowdown suggests, even while XRP’s market price has struggled.

Bitcoin ETF flows remain roughly $1 billion negative for 2026 after the earlier withdrawals. Against that deficit, $3.8 billion arriving in three weeks marks a decisive short-term turn.

With total assets back above $100 billion and three-week inflows at a yearly high, the spot ETF complex is again acting as a major source of demand. The next test is whether that buying holds if Bitcoin remains under pressure.

For now, the funds are answering that question with real money.
