The U.S. spot bitcoin ETF market, which had been a steady source of demand since its January 2024 launch, flipped to net outflows in May 2026. Monthly data shows year-to-date accumulation flattened to roughly 4,500 BTC, with May marking the first period of net redemptions. The shift comes as AI-driven equities — particularly mega-cap chipmakers — have driven the S&P 500 and Nasdaq to record highs, drawing capital away from crypto.
ETF outflows accelerate in late May
Outflow prints on May 27 and 28 were especially notable, signaling weakening demand after weeks of sideways price action. The broader May trend reversed the steady accumulation seen in the first four months of the year. Analysts at several trading desks had warned that funding rates were staying sticky into resistance, leaving the market vulnerable to a snap-back when leverage unwound.
The mid-May cascade
That unwind came between May 15 and 19, when forced liquidations totaled an estimated $650 million to $700 million across major exchanges. Bitcoin hit an intraday low near $76,270 on May 19 — a 15% drawdown from its recent highs. Crypto's higher leverage and 24/7 trading amplified the sell-off, turning what might have been a normal pullback in equities into a sharp cascade in digital assets.
Why AI is winning the flow battle
Mega-cap chipmaker rallies are benefiting from passive index flows that reinforce upward moves — a dynamic crypto lacks. The S&P 500 and Nasdaq both closed at record highs on May 8 amid an AI-led surge. Pairing bitcoin with AI exposure or using hedges has become a common recommendation for balancing factor tilts in an unstable correlation regime. For now, the correlation between bitcoin and tech stocks has weakened, leaving crypto to trade more on its own — and not in a good way.
The big question going into June: whether ETF outflows deepen or stabilize. If the AI rally continues to absorb risk appetite, bitcoin could struggle to reclaim the demand levels it enjoyed earlier this year.
