US spot Bitcoin ETFs recorded six consecutive weeks of net inflows from April 2 through May 9, 2026, accumulating $3.4 billion—the longest sustained inflow streak in over nine months. The streak eclipses the previous record of seven weeks set between June 13 and July 18, 2025, when ETFs pulled in $7.57 billion. Data from SoSoValue shows weekly inflows peaked at $996.38 million during the week of April 17, signaling renewed institutional appetite for regulated Bitcoin exposure.
Inflow Momentum Builds Despite Market Volatility
The six-week inflow sequence marks a significant reversal in ETF capital flows after months of mixed sentiment. The week of April 2 opened weakly with just $22.34 million in net inflows, but buying pressure accelerated sharply in mid-April. The strongest week—April 17—saw nearly $1 billion flow into spot Bitcoin ETFs, indicating coordinated institutional positioning. Most recent data through May 9 shows inflows of $622.75 million, though the final two trading days revealed minor outflows ($277.50 million on Thursday May 8 and $145.65 million on Friday May 9), suggesting profit-taking at resistance levels.
Geopolitical Risk and Employment Data Drive Flows
Market timing suggests external catalysts influenced the inflow pattern. Bitcoin price action remained volatile, trading below $80,000 on May 8 amid liquidation clustering at the $78,000 level and dense short positioning between $82,000 and $83,000. Broader macro uncertainty stemmed from conflicting US employment signals: the ADP reported 109,000 jobs added, sharply below the 62,000 consensus forecast. Bitunix analysts noted that geopolitical tensions—specifically US-Iran exchanges around the Strait of Hormuz—”continue to leave room for negotiations,” suggesting safe-haven Bitcoin demand persisted despite headline risk. Ethereum ETFs also recovered, posting $70.49 million in weekly inflows after prior outflows of $82.47 million.
Institutional Conviction Tested at Key Resistance
The six-week streak demonstrates sustained institutional conviction, though the pattern’s durability remains uncertain. Outflows on May 8-9 coincided with Bitcoin rejection near $80,000, a technical level that could determine whether inflows continue into May. The previous seven-week streak in summer 2025 generated $7.57 billion total—suggesting the current $3.4 accumulation still has room to accelerate if Bitcoin breaks above near-term resistance. Spot Bitcoin ETFs continue to serve as primary vehicles for regulated institutional exposure, with no official commentary yet from major issuers on motivations behind the sustained buying.
