Bitwise’s latest Ethereum factor model argues that, for all the progress in regulation, infrastructure, and on-chain adoption, ETH is still mostly trading in Bitcoin’s orbit. The report matters because it sharpens a debate many desks have been having for months: whether Ethereum is being priced on its own fundamentals or still behaving primarily as a high-beta expression of the broader crypto market.
Bitwise Finds Bitcoin Still Sets Ethereum’s Pace
Bitwise examined 406 weekly observations dating back to May 2018 to identify what has actually driven ETH returns across market regimes. Its conclusion was direct: “BTC is the dominant driver.” In the firm’s model, ETH moves “nearly 1:1 with BTC on a weekly basis,” with a coefficient of about 0.99, and Bitcoin alone explains roughly 65% of Ethereum’s return variance.
That finding stands out because it comes against a backdrop of improving Ethereum fundamentals. Bitwise notes that U.S. regulatory clarity has advanced through measures including FIT21 and the Genius Act, with the Clarity Act potentially arriving by year-end. Institutional access has also deepened through spot products and CME futures, while Ethereum still hosts more than half of the roughly $300 billion stablecoin market and about 60% of the $25 billion tokenized asset market.
Even so, ETH remains about 62% below its all-time high, leaving a visible gap between network positioning and price performance. Bitwise frames that disconnect in unusually explicit terms. “Adoption fundamentals, such as active addresses, clearly have less impact on Ethereum’s price than many assume. Extending this further, revenue generation appears even less relevant,” the report said, adding that revenue was removed from the model as “noise rather than signal.”
In practice, Bitwise’s work suggests the market is still treating Ethereum less like a cash-flow asset and more like a crypto macro vehicle. The report says this “supports the idea that since the start of the model in 2018, Ethereum has been priced more like a network-driven commodity than a business with durable cash flows.” That interpretation is reinforced by valuation indicators the firm tracks, including a long-term cycle indicator sitting at the 6th percentile while the price-to-sales ratio sits at the 99th percentile.
The regime analysis offers more nuance. BTC’s influence was strongest in periods when ETH functioned as either a levered Bitcoin trade or an asset stripped of idiosyncratic catalysts. Between June and August 2025, the BTC coefficient rose to roughly 1.5 to 1.6 as Ethereum rebounded from deep lows while Bitcoin pushed toward record levels, with macro easing providing the other major tailwind.
Bitwise also pointed to H2 2022, especially after the FTX collapse, as another BTC-dominant stretch. During that phase, returns were explained by Bitcoin to as much as 90%, while other factors carried negative coefficients. “In moments like these, cash liquidity is what matters. Not fundamentals, flows or macro. As such, ETH was essentially anchored to BTC,” the report said.
Macro and Flows Matter, but BTC Leads ETH Moves
If Bitcoin is the core driver, financial conditions are the most meaningful secondary one in Bitwise’s framework. Using the Bloomberg US Financial Conditions Index, the report found a coefficient of roughly 0.05 and average explanatory power of 11.3%, with peaks near 40%. The key point is that macro’s influence is dynamic rather than constant, becoming more relevant when liquidity conditions are shifting meaningfully.
Network activity had a smaller but still statistically significant role. Active addresses carried an approximate coefficient of 0.03, with average explanatory power around 6% and peaks near 30%. Bitwise highlighted May 2021 as a rare period of lower BTC sensitivity, when Bitcoin had already peaked but ETH kept rallying as active addresses surged to all-time highs during the NFT boom that followed DeFi Summer.
ETP flows were another interesting result. Their coefficient, at around 0.01, is small, but Bitwise said they explain about 10% of ETH variance on average and as much as 40% at peak. More importantly, the firm described flows as significant in 91% of weeks in the current regime, making them “the most statistically reliable flow-price relationship in ETH’s history,” even if each unit of flow now has less punch than before.
That distinction runs through the report’s broader takeaway. “Flows have become a persistent, dependable signal rather than a powerful one,” Bitwise wrote. In other words, they matter because they keep showing up, not because they overwhelm price formation. The report makes a similar argument on equities: the standalone equity factor turned out to be statistically weak, largely because Bitcoin already captures most of that broader risk-on and risk-off exposure.
The firm’s diagnostic tests suggest the model is usable and generally well behaved, with no major red flags around overlap or misspecification. But Bitwise is careful not to overstate its forecasting power. Out of sample, the richer GETS model did not beat a much simpler AR(1)+BTC specification, implying that for short-term prediction, Bitcoin exposure and basic price persistence still do most of the heavy lifting.
The report leaves Ethereum in a familiar but consequential position. Its market structure, institutional access, and regulatory footing continue to improve, yet price discovery still runs first through Bitcoin, with macro and flows acting as secondary modifiers. For traders and allocators, that means ETH may keep trading as a BTC-linked asset until the market begins to value tokenholder rights, usage, and revenues as primary anchors rather than background noise.
