Tom Lee Says Ethereum Could Outperform Bitcoin as ETH/BTC Ratio Signals Altcoin Strength

Ethereum may be entering a new phase of outperformance against Bitcoin, according to Fundstrat co-founder Tom Lee, who believes the ETH/BTC ratio is signaling a broader shift in crypto market leadership.

Lee has monitored the ETH/BTC ratio for months, describing it as a key indicator of market sentiment. He argues that the recent improvement suggests capital could increasingly rotate from Bitcoin into Ethereum and other higher-risk digital assets during the second half of 2026.

The strategist attributes Ethereum’s strengthening outlook to several factors, including the rapid expansion of stablecoins, growing adoption of tokenized real-world assets, and the emergence of new Ethereum-based spinoff projects. He also pointed to easing oil prices and progress on the U.S. CLARITY Act as additional catalysts supporting Ethereum’s long-term investment case.

“There are reasons for the ETH/BTC price ratio to rise in 2H2026. In short, the ETH is money narrative likely gains traction,” Lee said.

Lee’s bullish outlook aligns with Bitmine’s aggressive Ethereum accumulation strategy. The firm has steadily increased its ether holdings throughout a prolonged buying phase, although Lee recently indicated that the company’s large-scale accumulation could be approaching its conclusion. Earlier this year, he also dismissed a sharp ether selloff as routine quarter-end portfolio rebalancing rather than a sign of deteriorating fundamentals.

The ETH/BTC ratio is widely followed by cryptocurrency traders as a measure of risk appetite across the digital asset market. Historically, a sustained rise in the ratio has coincided with stronger performance from altcoins as investors diversify beyond Bitcoin.

Despite the recent rebound, challenges remain. The ETH/BTC ratio briefly reached 0.15 during the 2017 bull market but has remained below that level ever since. Lee’s ambitious $250,000 Ethereum price target would imply an ETH/BTC ratio more than 25 times higher than its previous peak, assuming current Bitcoin prices remain unchanged.

The ratio is still down 7.72% over the past three months, while spot Ethereum exchange-traded funds experienced seven consecutive weeks of net outflows in late June before showing signs of stabilization. Whether the current breakout can be sustained through 2026 will determine if Ethereum is entering a lasting leadership cycle or if Lee’s optimistic forecast proves premature.
