Bitcoin ETF Comeback: $2.4B Week Flips Year-to-Date Flows Positive

It was hard to imagine after June ended and the massive outflows recorded within the first six months of the year, but the spot BTC ETFs have managed to turn the tables and are actually well in the green now YTD.

The spot Ethereum ETFs have erased last week’s losses, and the cumulative net inflows are up to nearly $14 billion again.

BTC ETFs Back in Green YTD

As reported earlier this week, the Monday numbers set a multi-month record in terms of daily inflows as investors inserted almost $1 billion within a single trading session. Although the inflows declined by the end of the week, they were still in the green. $714.75 million entered the funds on Tuesday, another $346.98 million on Wednesday, $190.65 million on Thursday, and $134.47 million on Friday.

Consequently, this pivotal week ended with $2.39 billion in net inflows for the spot Bitcoin ETFs, pushing the cumulative total net inflows to $57.55 billion. As mentioned above, the YTD numbers have turned green, which was nearly impossible after June. At the time, investors pulled out a record $4.51 billion from the funds, which followed a painful May with $2.43 billion in net outflows. YTD, the funds were nearly $5.5 billion in the red.

However, the narrative shifted in July with a modest $172 million in net inflows, but it skyrocketed in August and September. The ETFs attracted $3.52 billion in August and are up by $2.7 billion so far in September. As such, the 2026 numbers are at $925 million in the green.

At the same time, though, the underlying asset remains 40% away from its all-time high. Crypto Rover believes this difference won’t last long, as “institutional money is accumulating like never before and has shortened the bear market dramatically.”

THIS IS INSANE:

Bitcoin is still more than 40% away from its all time high.

Meanwhile, spot cumulative ETF flows are only 10% away from their all time highs.

ETH ETFs in Green Too

The exchange-traded funds tracking the largest altcoin also enjoyed a strong start to the business week, gaining almost $270 million on Monday. They also saw green-only in the following four trading days and ended with $689.88 million in net inflows. Thus, they offset all the losses from the previous business week by a large margin and hit a new multi-month high in terms of cumulative net inflows of $13.94 billion.

Meanwhile, the underlying asset touched $2,800 during the week but was stopped there and now trades at around $100 lower.
