Bitcoin ETF Outflows Reach $648.64M as Long-Term Holders Absorb Supply and Funding Turns Positive
U.S. spot Bitcoin ETFs saw $648.64M in one-day outflows, yet long-term holders kept accumulating as funding flipped positive and open interest stayed elevated despite price pressure.

A sharp wave of U.S. spot Bitcoin ETF redemptions—$648.64 million on Monday—hit the tape just as long-term holders kept soaking up coins. Price action reflected the stress: Bitcoin slid 6.7% from $81,700 last Thursday to a $76,201 weekly low and hovered near $76,680 at press time, down 0.7% over 24 hours. ETF flows were lopsided: BlackRock’s IBIT logged $448 million of outflows, ARK/21Shares saw $110 million, and Fidelity shed $63 million. That followed roughly $1 billion in net redemptions last week.
What pushed funds to lighten up wasn’t mysterious. Agne Linge at Wefi pointed to broad de-risking tied to escalating U.S.-Iran tensions. Illia Otychenko at CEX.IO highlighted last week’s U.S. inflation print, which skewed expectations toward a rate hike this year rather than cuts. Prediction markets echo the hawkish shift: on Myriad, users assign just a 2% chance of a 25 bp cut in June and 4% odds of larger cuts before July. Anxiety also picked up after Donald Trump’s “calm before the storm” post, adding to geopolitical risk pricing. The Crypto Fear and Greed Index slipped to 25—“Extreme Fear.”
The more important tension sits beneath the headlines: ETFs are selling, but long-term holders keep buying. That tug-of-war often decides whether dips cascade or get absorbed. Otychenko noted these cohorts have been accumulating for months at a pace outstripping MSTR’s bidding, even as a larger slice of their coins moved into unrealized loss—behavior that generally caps downside by tightening tradable float. When veteran wallets tolerate drawdowns and continue to add, order books tend to refill faster on slides, and forced sellers meet real demand instead of empty air pockets.
Derivatives are signaling that reflex, not capitulation, is in play. Aggregate open interest fell from $29 billion to $26 billion over two weeks, per CryptoQuant—lighter, but still high versus recent norms, which implies ongoing speculation rather than an exodus. Funding rates flipped positive after months in the red, suggesting new longs are stepping in despite last week’s $670 million in liquidations. Positive funding this early in a pullback can be double-edged: it shows confidence returning, but it also means fresh longs can be vulnerable if macro headlines worsen.
One structural wildcard could add intermittent bid support. K33 Research’s Vetle Lund has argued that issuance tied to Strategy’s perpetual preferred, Stretch (ticker STRC), may help produce recurring mid-month BTC pops. Otychenko agrees the effect can partially or even fully offset ETF outflows at times, but he cautioned it wasn’t sufficient on its own to drive sustained recoveries—citing late January and early February when Strategy-linked demand exceeded ETF redemptions without meaningfully lifting price.
Put together, the tape looks like a classic flow mismatch: mandated sellers in regulated wrappers responding to macro/geopolitics, and patient balance-sheet buyers gradually retiring supply. If ETF outflows persist, price may chop until marginal demand—macro or corporate—reappears. If long-term holders keep absorbing while funding stays modestly positive and open interest normalizes rather than spikes, sellers are likely to run into support zones rather than air pockets.
Positioning expectations mirror that nuance. Myriad’s crowd still leans bullish on the next leg targeting $84,000 with a 77% probability, down from 89% last week—optimism tempered, not erased. In this phase, I’d anchor on three gauges: breadth of ETF outflows (with IBIT’s $448 million as a bellwether), durability of positive funding after the $670 million flush, and whether long-term holder accumulation persists even as unrealized losses creep higher. If those hold, downside looks contained; if any crack, volatility probably expands.
