Bitcoin slid below the $75,000 mark in late May 2026 after one of the heaviest stretches of institutional selling on record, with US spot Bitcoin ETFs absorbing roughly $2.1 billion in net outflows for the month — the largest monthly redemption since the products launched.
BlackRock’s iShares Bitcoin Trust (IBIT), the largest of the spot vehicles by assets under management, lost approximately $528 million in a single trading session as redemptions accelerated. SoSoValue data shows total year-to-date net outflows across the eleven US spot ETFs reaching roughly $596 million, a reversal from the strong accumulation pattern that defined late 2025.
What’s driving the unwind
The pullback coincides with a broader risk-off rotation in global markets and renewed macroeconomic uncertainty around US trade policy. Glassnode on-chain data shows long-term holders broadly maintaining their positions, with short-term holders absorbing the majority of distribution pressure. The supply held by wallets aged six months or older has continued to climb through the correction.
Farside Investors’ ETF flow tracker confirms that May’s outflow concentration occurred across multiple issuers, not just BlackRock — meaning the move is institutional in character rather than a single fund’s rebalancing.
Where the floor might sit
Polymarket contracts pricing Bitcoin to dip below $55,000 before year-end have shifted to roughly 18% implied probability — elevated but well below the panic levels seen in past corrections. Technical analysts at firms including Mudrex point to the $72,000–$74,000 zone as the next major support cluster, derived from the early-2026 accumulation range.
For now, the ETF unwind is the dominant market signal. Whether the institutional cohort that drove Bitcoin’s 2024–2025 rally treats the $75,000 zone as a buying opportunity or a confirmation of a deeper downtrend will likely determine the shape of summer trading.
