Bitcoin ETF Demand Fades as May Turns to Distribution After Strong Spring
U.S. spot bitcoin ETFs have accumulated only a net 4,500 BTC since the start of 2026, a stark contrast to the structural buying that fueled the 2025 rally, according to Swissblock data. March and April saw steady accumulation that helped lift bitcoin from lows near $65,000, but May has reversed course with just three days left in the month. Swissblock's Risk Index has moved into high-risk territory while ETF flows deteriorate, indicating that spot ETF demand is no longer effectively absorbing selling pressure. This reversal matters because previous rallies relied on ETF buying to clear supply from miners and other sellers. Bitcoin traded at $75,808 on Tuesday, down 2.6% over the past month, and is near the bottom of its May range. Other cryptocurrencies like ETH, XRP, and Solana also declined. On-chain data shows apparent demand has slid to its weakest level since December, with $1.74 billion in ETF withdrawals over the past two weeks. However, it remains unclear whether this is a pause or a turn, as ETF buying has dropped before without leading to deeper drawdowns. A potential golden cross between bitcoin's 50-day and 200-day moving averages offers a bullish signal, but the fading ETF demand could weaken the structural case for the rally that began in April.
