USDT and USDC surge while BTC share of crypto market contracts
Bitcoin’s share of total cryptocurrency market value has declined to 60% from 61.20% since May 5, marking a measurable shift in trader preference toward dollar-pegged assets. Tether’s USDT dominance rose from 7% to 7.5% in the same period, while Circle Internet’s USDC climbed from 2.8% to 3%, according to CoinDesk reporting on May 27, 2026.
The capital rotation reflects a pattern last observed in late January 2026, just before Bitcoin prices fell to $63,000 in early February. Bitcoin traded at $75,892.91 at the time of writing on May 27, down from a recent high of $75,900 and a low of $75,200 early that morning.
Alex Kuptsikevich, Chief Market Analyst at FxPro, characterized the shift as a signal of profit-taking in risk assets. “If cryptocurrencies are once again acting as a barometer of sentiment in global financial markets, this looks like an early signal of a reversal towards profit-taking. Perhaps investors prefer to take their money off the table ahead of the start of summer, beginning with the riskiest segment,” Kuptsikevich said.
Higher interest rates make dollar-denominated investments more attractive relative to Bitcoin, which generates no inherent yield or cash flow. Gold and precious metals funds have also attracted investor capital in the same period, according to the reporting.
The stablecoin preference coincides with broader market volatility. The Nasdaq e-mini futures reached a record high of 30,000 points, while WTI oil prices declined 3% to $90 per barrel. A $1.29 billion block trade of BlackRock’s IBIT Bitcoin ETF shares executed in a dark pool underscored institutional repositioning. The trade followed $333 million in outflows from 11 spot Bitcoin ETFs on Tuesday and $2.26 billion in total ETF outflows over the preceding two weeks.
Altcoins declined alongside Bitcoin. Ether, XRP, Solana, and the CoinDesk 20 Index each dropped approximately 2% in 24 hours. At one point earlier in May, Bitcoin had fallen to the 13th largest asset globally when priced near $76,000.
The U.S. ADP employment report was scheduled for release on May 27 and posed a potential source of additional market volatility, though the exact timing was not specified in available reporting.
Capital Rotation Pattern
The current shift mirrors dynamics from late January 2026, when similar stablecoin preference preceded a sharp Bitcoin selloff. The pattern suggests traders may be using stablecoins as a temporary holding mechanism during periods of market uncertainty, rather than committing capital to riskier digital assets.
Bitcoin dominance, measured as a cryptocurrency’s percentage share of total digital asset market capitalization, serves as a key metric for tracking institutional and retail trader positioning. The 1.2 percentage point decline in Bitcoin dominance since May 5 represents a material reallocation of capital within the crypto ecosystem toward yield-bearing dollar equivalents.
