Bitcoin's selling pressure indicator has entered a 'high-risk' zone, primarily driven by a significant slump in U.S. spot Bitcoin ETF demand. After strong buying through March and April, May saw a reversal, with ETFs accumulating a net 4,500 BTC since the start of 2026, a stark slowdown. This shift suggests institutional interest is waning, removing a key support for BTC prices. Investors should monitor ETF flow trends closely, as sustained outflows could signal further price weakness and a deeper market correction. This development highlights a critical change in market dynamics from earlier this year.
The dramatic slowdown in U.S. spot Bitcoin ETF accumulation, particularly the May reversal, signals reduced institutional demand. This removes a significant buying pressure, making Bitcoin more vulnerable to downside price movements. Sustained weak ETF flows will likely weigh on BTC's price discovery.
This story reveals a market grappling with diminishing institutional enthusiasm, shifting from strong ETF-driven accumulation to net selling pressure. The market's current structure lacks a clear bullish catalyst, implying a period of consolidation or further downside until new demand emerges.
U.S. spot bitcoin ETFs have accumulated a net 4,500 BTC since the start of 2026, with May reversing the buying pattern that built through March and April, per Swissblock data.
