Two inflow days in thirteen. That’s the story of Bitcoin ETF flows since May 11, 2026. The entire market, BlackRock, Fidelity, ARK, Grayscale, Bitwise, and the rest, produced net outflows on eleven of the thirteen trading days shown in the data, with two brief positive sessions on May 11 and May 14 that didn’t change the overall direction.
The BlackRock picture
IBIT had one positive session in the entire thirteen-day window. According to data from Farside Investors, on May 14 it recorded $144.1M in inflows, the only green day in the dataset for BlackRock’s fund. Every other session was red.
May 15 opened the streak with $136.2M out. May 18 was the single largest IBIT outflow day in the period at $448.4M. May 19 added $325.6M. The pace moderated through May 20-22 with three days in the $60-100M range before selling picked back up. May 27 produced the largest single-day IBIT outflow in the entire dataset at $527.8M. May 28 added $177.9M. May 29 brought $68.2M, the smallest outflow in the streak.
Adding it up: IBIT recorded approximately $2,435M in outflows over the thirteen-day period against $144.1M in inflows on May 14. Net outflow from BlackRock’s fund alone: approximately $2.29B in two weeks.
The full ETF picture
IBIT wasn’t the only one bleeding. The total outflow picture across all providers shows the same pattern at a larger scale.
May 13 was the first major shock day at $630.4M total, driven by $284.7M from IBIT and $177.1M from ARK’s ARKB alongside $133.2M from Fidelity. May 14 provided a brief reprieve with $131.3M in total inflows, again led by IBIT’s $144.1M. But that one-day pause didn’t hold.
May 18 became the second worst single day of the period at $648.6M total, IBIT contributing $448.4M, ARK $109.6M, and Fidelity $63.4M all moving in the same direction. May 19 added another $331.1M. The following three days, May 20, 21, 22, saw the total moderate to $70-105M per day before selling picked back up again.
May 26 reopened with $333.6M in total outflows. May 27 was the worst single day of the entire period at $733.4M, IBIT’s $527.8M combined with $104.8M from Grayscale GBTC, $60.3M from Fidelity, and smaller contributions from ARK and Grayscale’s BTC fund. May 28 added $223.3M. May 29 brought $125.3M.
Net across all thirteen days: approximately $3.83B in total outflows against $158.5M in total inflows on May 11 and May 14. Net outflow for the period: approximately $3.67B.
What the provider breakdown shows
BlackRock’s IBIT drove the majority of the outflows, roughly 62% of total net outflows came from a single fund. Fidelity’s FBTC was a consistent secondary contributor with outflows on most days. ARK’s ARKB had two significant single-day outflows on May 12 and May 13 before going largely quiet. Grayscale’s GBTC, the fund that previously bled $21B after its ETF conversion, contributed notably on May 27 with $104.8M, its largest single day in this dataset.
Morgan Stanley’s MSBT was largely flat throughout. Bitwise BITB had moderate outflows on several days. The smaller providers, VanEck HODL, WisdomTree BTCW, Invesco BTCO, Franklin EZBC, contributed minimally or not at all on most days.
The pace on May 29
May 29’s $125.3M total is noticeably smaller than the days before it. After three sessions of $223M, $733M, and $223M, a $125M day stands out. IBIT’s $68.2M is its smallest outflow since May 20’s $61.5M.
Nobody knows yet if the selling is actually slowing or just taking a breath. Trump’s Iran deal framework posted on May 29 may be taking some pressure off, geopolitical uncertainty has been the clearest backdrop for the selling throughout this period. If the deal framework holds and confirmation follows, the next few sessions could look very different from the past ten.
Thirteen days. Two positive sessions. $3.67B net out. The streak that followed May 14 is now ten days long for IBIT and the broader market alike. May 29’s lighter numbers are the first sign it might be running out of momentum or just pausing before the next leg.
