Last week saw continued momentum in US-listed spot Bitcoin (BTC) ETFs, with a net inflow streak now extending to six consecutive weeks. Over this period, inflows have totaled $3.4 billion into these funds, highlighting sustained investor appetite. While the week began with significant new investments, Thursday and Friday stood out for major outflows, a sign of ongoing volatility in ETF trading patterns.
Six-week inflow run continues
According to SoSoValue data, the robust inflows that began on April 2 have driven total net investments in US-based Bitcoin ETFs to more than $3.4 billion. This six-week stretch marks the longest positive run for spot BTC ETFs since July of last year. During this window, mid-April even saw nearly $1 billion in new weekly investments, underscoring especially strong institutional demand.
In the most recent week, net new inflows reached $622.75 million—even as notable outflows occurred late in the week. Thursday recorded withdrawals of $277.5 million, and Friday saw outflows totaling $145.65 million. Despite these sizeable exits, the week’s overall trend remained net positive.
Institutional interest fluctuates
ETF demand started this week at a robust pace, with investors pouring in a combined $999 million on Monday and Tuesday alone. However, that strong momentum faded midweek, giving way to sizeable withdrawals as the week came to a close, reflecting mixed institutional sentiment.
This six-week positive period marks the second-longest inflow streak on record, only surpassed by the seven-week run between June and July 2025. During that historic window, inflows reached approximately $7.57 billion, setting a benchmark for future ETF performance.
The surge in weekly ETF inflows points to a renewed sense of institutional investor confidence returning to the market.
Since spot Bitcoin ETFs were first introduced in the United States, there has been a marked increase in institutional involvement. Recent net inflows confirm that appetite for these products remains strong, despite short-term fluctuations in fund activity.
Latest BTC and ETH price movements
Bitcoin’s price tracked ETF flows closely over the past week, trading within a volatile range. BTC managed to hold above the psychologically important $80,000 mark, at times approaching $82,000 in tandem with surging inflows. Toward the end of the week, as outflows took hold, Bitcoin retreated but ultimately stabilized at around $80,800. According to CryptoAppsy, BTC held near this level as the weekend began.
Meanwhile, Ethereum-focused ETFs reversed the previous week’s trend by returning to positive territory. For the week ending May 8, net inflows into ETH ETFs reached $70.49 million, recovering some of the $82.47 million in outflows from the prior week and signaling renewed interest among investors in Ethereum-linked funds.
