In the week spanning from May 4 to May 8, US spot Bitcoin ETF products experienced an impressive influx of $622.75 million, marking their sixth consecutive week of net inflows.
This data was tracked by SoSoValue and reported on May 11. BlackRock’s IBIT led the charge with a substantial $596 million in net inflows, while Grayscale’s GBTC stood out as an exception with a notable outflow of $62 million during the same timeframe. As it stands, IBIT’s cumulative total has reached an impressive $66.1 billion.
Six Weeks and What Lies Ahead
This ongoing streak represents the longest period of inflows for US spot Bitcoin ETFs since they recorded seven consecutive weeks between June and July in 2025. Over these six weeks starting April 2, these funds have collectively absorbed nearly $3.4 billion in new investments.
The peak week occurred in mid-April when inflows soared to $996.38 million; last week’s figure of $622.75 million ranks as the second-highest total during this streak. Throughout this period, Bitcoin traded within a range of approximately $80,000 to $82,000 before stabilizing around the weekend at about $80,800.
Additionally, spot Ethereum ETFs attracted net inflows totaling $70.49 million over that same week; meanwhile, spot Solana ETFs garnered interest with gains of $39.23 million and spot XRP ETFs drew in approximately $34.21 million.
Institutional Positioning and Context
The recent six-week surge is indicative of sustained institutional demand that has seen IBIT capture most industry flows throughout 2026 thus far—IBIT accounted for a staggering 73% share of Bitcoin ETF inflows during January’s reporting period from January 12 to January 16—a trend that continues across subsequent reports.
Jake Seltzer, CEO of Quantix Finance commented this week that “the market is transitioning into a phase where liquidity is becoming more selective rather than purely speculative,” suggesting that these influx figures reflect structural institutional rotation towards Bitcoin.
