According to a new analysis by on-chain data platform CryptoQuant, Bitcoin (BTC) and Ethereum (ETH) are operating under fundamentally different supply-demand regimes in 2026. The key takeaway is that Bitcoin dominance will persist until Ethereum demonstrates sustained spot buying similar to BTC.
Spot Demand Driving Bitcoin's Recovery
Bitcoin's April rebound was fueled by genuine spot demand. Data shows U.S. spot Bitcoin ETFs recorded $532 million in net inflows on May 4 alone, marking the third consecutive day of positive flows. For the entire month of April, BTC ETF net inflows reached $2.44 billion, the strongest monthly institutional buying figure in nearly eight months. CryptoQuant analysts note that real buyers are accumulating BTC via ETFs or direct purchases, removing supply from exchanges and creating a bullish structural force.
Ethereum Spot Demand Lags Behind
In contrast, U.S. spot Ethereum ETFs logged only $61.29 million in net inflows on May 4, a positive but much smaller figure. The scale and consistency of institutional ETH flows have not matched Bitcoin's trend. Ethereum's price recovery remains more dependent on leverage futures and perpetual contracts, which introduce volatility without reducing available supply. CryptoQuant emphasizes that until ETH shows persistent spot buying, its price action will remain vulnerable to sharp corrections.
Spot vs. Leverage Demand: Why It Matters
The distinction between spot and leverage demand is critical for price stability. When BTC is accumulated via spot ETFs or direct purchases, supply is taken off exchanges, supporting prices even during low volume. In contrast, demand driven by futures and perpetuals creates short-term price pressure without removing supply. Leveraged positions can unwind quickly when conditions change, as demonstrated on Tuesday when a trader was liquidated on a 700 BTC short position, losing $1.94 million as BTC surged above $81,000.
Roadmap for Altcoin Season
For those tracking whether a broader crypto market expansion will materialize in 2026, CryptoQuant provides a clear roadmap: monitor U.S. spot Ethereum ETF flow data, watch ETH supply on exchanges, and track whether Ethereum's discount to its all-time high begins closing faster than Bitcoin's. Only when these indicators align to show rising spot demand for ETH can traders expect Bitcoin dominance to wane, potentially unlocking an altcoin rally.
