Analysts’ Assessments of Causes and Consequences
Experts at Wintermute emphasize that the key risk for the market remains the flows into spot Bitcoin ETFs. They note significant outflows from these products in recent weeks, which they believe is related to a decrease in institutional demand. Analysts explain that part of the margin risk capital has shifted from digital assets to stocks.
“The risk index for Bitcoin is entering a zone of heightened danger. This is occurring against the backdrop of deteriorating inflows into spot Bitcoin ETFs.”
At Swissblock, they believe that this trend indicates institutional distribution, meaning the pressure from sellers outweighs demand in the market. According to their calculations, since the beginning of 2026, the net inflow into spot Bitcoin ETFs has decreased to about 4500 BTC.
At the same time, according to Timothy Misira, head of research at BRN, outflows from Bitcoin ETFs do not signify a complete exit of institutional investors from the market.
It is worth noting that from May 18 to 22, 2026, the spot Bitcoin ETF sector in the US experienced a significant capital outflow of $1.26 billion, marking the fourth-largest weekly outflow in the history of this segment and the third such occurrence in 2026.
