Bitcoin fell 9% in 48 hours, and the selloff was tied to several pressures hitting the market at once. U.S.-listed spot Bitcoin ETFs posted $2.1 billion in net outflows between May 12 and May 20, while derivatives data showed little sign of stronger institutional demand stepping in.
ETF withdrawals deepened the pressure
The clearest stress point was fund flow. According to the source material, U.S. spot Bitcoin ETFs lost $2.1 billion over that period, a sizable withdrawal during an already fragile stretch for crypto. Futures data told a similar story. The annualized premium for BTC futures has stayed below the 4% neutral line for more than three months, a sign that demand for leveraged long exposure has remained soft.
Another shift showed up in cross-market behavior. Bitcoin had maintained a tight correlation with U.S. small-cap stocks through May 21, but that relationship then broke down. After nearly two months of moving in parallel, the divergence pointed to a change in how investors were pricing risk across asset classes.
Strategy’s change in pace drew attention
Market participants also focused on Strategy, led by Michael Saylor and known as one of the largest corporate Bitcoin investors. The company chose to repurchase its convertible debt and paused its steady Bitcoin buying program. That change was enough to trigger fresh speculation about how one of the market’s most closely watched corporate buyers is now positioning itself.
Some comments on X said the company may be placing more emphasis on balance sheet management. Arca Investment Director Jeff Dorman took a harsher view, calling the decision “a complete balance sheet management error.” The reaction highlighted how sensitive the market can be when a major buyer slows or stops a familiar accumulation pattern.
AI stock concentration and macro fears added to the selloff
Capital rotation into artificial intelligence names added another headwind. Jim Bianco, founder of Bianco Research, said the market has not seen this level of concentration around a single theme in years. JPMorgan research said 41 AI-related stocks now make up half of the S&P 500’s total market value. As that trade gained momentum, crypto assets faced stronger competition for investor capital.
Macro concerns were also building. The source said there were no signs that the war in Iran would de-escalate soon, pushing investors toward a more cautious stance on risk assets. At the same time, CME FedWatch data showed the probability of a rate hike at the September FOMC meeting rising to 23%, up from zero a month earlier. That shift left markets preparing for tighter policy to remain in place longer than previously expected.
Taken together, the decline reflected a combination of heavy ETF outflows, weak futures demand, a change in Strategy’s buying behavior, capital moving toward AI equities, and a colder macro backdrop.
