Ethereum (ETH) has historically struggled to maintain its outperformance against Bitcoin.
From a technical perspective, ETH/BTC last posted a strong quarterly gain in the third quarter of 2025, up 53%, marking its biggest quarterly gain since the second quarter of 2021. However, as the rally lost momentum, sellers erased 50% of these gains. This suggests that the rotation is temporary as capital continues to flow into Bitcoin.
Against this backdrop, the 5% rise in the rate so far in the third quarter seems too early to confirm a sustained pivot from Bitcoin to Ethereum. At the same time, Bitcoin dominance is once again moving towards the key resistance level of 60%, up 1.5% in July, signaling that capital is already returning to Bitcoin.
However, Eric Trump’s latest post about X-dots is in the opposite direction, supporting Ethereum’s rally.
Meanwhile, on-chain data tells a similar story. of Ethereum superior performance against Bitcoin (BTC) It doesn’t happen alone. Corporate positioning continues to support this move; Ethereum ETFs have outperformed Bitcoin, attracting over $128 million in net inflows so far this month. Meanwhile, Ethereum’s DATs are improving, providing further support to Ethereum’s recent strength.
However, it may be too early to write off the current ETH/BTC uptrend as another short-term rotation. The bigger question is whether the smart money is positioning itself ahead of a structural change that the broader market has not yet priced in.
Ethereum’s latest catalyst brings the ETH/BTC ratio to the fore
A key catalyst could be strengthening institutional rotation towards Ethereum.
Tom Lee noted that Robinhood’s recently introduced Layer 2 chain is a significant differentiator, calling it a groundbreaking product that currently generates more volume than many established DEXs. More importantly, the network uses ETH as its gas token and is placed in Ethereum Layer 1. As activity on the chain grows, each transaction feeds back into Ethereum’s ecosystem, strengthening long-term demand. case for ETH.
On-chain data supports this. As the chart below shows, the amount of ETH bridged from Ethereum Layer 1 to Robinhood Chain increased almost 10x last week, surpassing $100 million. This shows that users are actively moving liquidity into Robinhood’s Layer 2 ecosystem, and ETH is emerging as the network’s core asset for gas, swaps, and on-chain activities.
In this context, Ethereum’s outperformance against Bitcoin may be more than just another rotation.
Instead, the move increasingly appears to be driven by improving fundamentals, as institutional flows, increased Layer 2 activity, and increased on-chain demand continue to strengthen Ethereum’s long-term investment case. If this trend continues, the breakout in ETH/BTC could be the first sign of a broader capital rotation towards Ethereum by the third quarter.
Final Summary
- Ethereum’s rise against Bitcoin is supported by ETF inflows, stronger on-chain activity and Robinhood’s Layer 2 ecosystem.
- If these trends continue, the breakout in ETH/BTC could signal a broader shift of capital into Ethereum in the third quarter.
