Asset manager Bitwise has published a comprehensive factor-model analysis revealing that Ethereum's (ETH) price action is overwhelmingly driven by Bitcoin (BTC) market movements, not by its own network fundamentals. The study, based on 406 weekly observations dating back to May 2018, found that Bitcoin alone explains approximately 65% of Ethereum's return variance, with ETH moving "nearly 1:1 with BTC on a weekly basis" and a coefficient of roughly 0.99.
This finding helps explain the persistent disconnect between Ethereum's price and its institutional progress. Despite improved regulatory clarity, broadened institutional access, and Ethereum's dominant role in stablecoin and tokenized-asset activity, ETH remains about 62% below its all-time high. Bitwise's report bluntly states that "adoption fundamentals, such as active addresses, clearly have less impact on Ethereum's price than many assume," and that revenue generation was removed from the model as "noise rather than signal."
The analysis identified secondary factors influencing ETH price, but their impact is significantly smaller. Financial conditions, measured by the Bloomberg US Financial Conditions Index, emerged as the second most important variable with an average explanatory power of 11.3%, peaking near 40%. Network activity, proxied by active addresses, averaged 6% explanatory power, rising to 30% in stronger phases. Ethereum ETF flows, while "highly significant," explained about 10% of variance on average.
The dynamic becomes even more pronounced during market stress periods. Between June and August 2025, Ethereum behaved like a levered Bitcoin trade, with its BTC coefficient rising to between 1.5 and 1.6 as BTC approached fresh highs. During the post-FTX stress in late 2022, Bitcoin explained up to 90% of ETH returns, with all other factors carrying negative coefficients. Bitwise noted that "in moments like these, cash liquidity is what matters. Not fundamentals, flows or macro. As such, ETH was essentially anchored to BTC."
The report acknowledges brief exceptions, such as May 2021 when Ethereum continued rallying during the NFT boom despite Bitcoin having already peaked. However, these windows are described as episodic rather than structural. Bitwise's broader conclusion is that Ethereum occupies a "paradoxical position"—a network with deepening institutional relevance but a price still driven mostly by external beta. At the time of the report, ETH traded at $2,305.
