Spot BTC ETFs log 6th straight week of net inflows, first in 9 months

US spot Bitcoin exchange-traded funds (ETFs) extended their run of weekly inflows to a sixth straight week, marking the longest streak of net purchases since August 2025. Data tracked by SoSoValue shows a six-week accumulation totaling about $3.4 billion, underscoring renewed appetite from ETF investors for spot BTC exposure even as intraday price action remains choppy. The week of April 2 through the latest period saw inflows peak in mid-April, with the strongest week recording nearly $1 billion in new money, while the weakest week started with only about $22 million of inflows.

Specifically, the week of April 17 delivered the largest weekly intake at $996.38 million, and the most recent week logged $622.75 million. This six-week ascent stands as the longest such streak in more than nine months; the prior longer run stretched for seven weeks from June 13 to July 18, 2025, totaling roughly $7.57 billion in inflows, including $2.72 billion in the week of July 11 and $2.39 billion the following week.

But the latest cadence was not uniformly uplifting. The week ended with notable outflows—$277.50 million on Thursday and $145.65 million on Friday—before a strong start earlier in the week. Monday and Tuesday delivered $532.21 million and $467.35 million respectively, while Wednesday’s inflows slowed to $46.33 million, illustrating a market tug-of-war as participants weighed macro signals against price action in BTC.

Key takeaways

• Six consecutive weeks of net inflows into US spot BTC ETFs, totaling about $3.4 billion from early April through the latest week, according to SoSoValue data.
• The six-week sequence is the longest since August 2025, with the strongest weekly inflow at $996.38 million (week of April 17) and the weakest in the six-week sample at $22.34 million (week of April 2).
• Bitcoin ETF inflows have shown episodic strength despite intermittent late-week outflows, highlighting ongoing demand from institutional and accredited investors seeking direct BTC exposure via regulated vehicles.
• Ether ETFs turned positive for the week ending May 8, posting $70.49 million in net inflows after prior outflows, extending a broader rebound in mid-to-late April.
• The macro backdrop remains a source of ambiguity, with investors awaiting key US data and ongoing geopolitical considerations that influence risk sentiment and liquidity in crypto markets.

Ether ETFs rebound after a stretch of volatility

While Bitcoin-led products dominated headlines with persistent inflows, Ether ETFs also flipped back into positive territory for the week ending May 8, recording net inflows of $70.49 million. This followed a prior period in which Ether inflows flipped to outflows totaling $82.47 million.

The sector had demonstrated notable momentum earlier in April, supported by a three-week run from April 10 to April 24 that produced combined inflows of $617.91 million and peaked at $275.83 million in the week of April 17. That momentum appeared to waver in the week that followed, but the May 8 data point signaled a renewed interest in ether exposure among ETF participants.

From a daily perspective, Ether fluxes within the week showed some volatility: Thursday saw $103.52 million in outflows, a pressure point that nearly erased gains built earlier in the week; Monday and Tuesday brought $61.29 million and $97.57 million in inflows, respectively, while Wednesday posted a modest $11.57 million in inflows. Friday managed a slight recovery of $3.57 million, leaving the week in positive territory.

Context: what the latest inflows imply for the market

Taken together, the data points to a persistent, though nuanced, demand signal for regulated crypto access via ETFs. The Bitcoin inflow trajectory suggests that a broad cohort of investors views spot BTC exposure as a core hedge or diversification tool within a regulated framework, even as daily price moves and systemic liquidity conditions inject volatility into short-term performance figures.

Analysts have noted that the macro environment—especially labor market signals and geopolitical developments—will help determine the pace and durability of ETF inflows in the near term. As traders await key economic releases and policy cues, risk management and liquidity considerations remain central to positioning around BTC and ether ETF products. The broader takeaway is that while inflows are not a straight-line rally, the sustained buying interest in spot BTC ETFs points to growing mainstream acceptance of regulated crypto exposure as part of diversified portfolios.

What traders should watch next

The coming weeks will likely hinge on domestic macro data and the evolving geopolitical backdrop, which jointly influence risk appetite and liquidity for crypto instruments. If the current inflow streak persists, ETF-backed BTC exposure could remain a meaningful driver of demand, particularly as institutions continue to explore regulated access. Conversely, back-end volatility and late-week reversals underscore the importance of disciplined risk management for ETF traders and market makers as they calibrate hedges and liquidity provision around volatile price levels.

Investors should also monitor Ether ETF flows for signs of a broader reset or renewed interest in ether exposure, especially given the mid-April surge and the subsequent rebound observed in early May. As always, the interplay between futures dynamics, spot liquidity, and regulatory developments will shape the path of both BTC and ether ETF products in the near term.

In the meantime, market watchers will want to keep an eye on the next batch of weekly ETF data, as well as daily price action around key support and resistance zones, to assess whether the current inflow pattern translates into more durable demand or remains a series of episodic, data-driven bursts.
