I See Ethereum Potentially Hitting $8.5K if Bitcoin Reaches $150K

I believe Ethereum could climb above $8,500 if Bitcoin rallies to $150,000, based on patterns from prior bull markets and historical ETH–BTC market-cap relationships. In 2021, Ether reached roughly 36% of Bitcoin’s market cap, and I think a similar dynamic could play out again as BTC gains strength.

If Bitcoin moves from around $119,335 to $150,000 (a ~25% rise), I estimate Ether could reach about $8,656 assuming a 35% market-cap share. Even with a more conservative ETH share between 21.7% and 30%, ETH would still trade in the $5,376–$7,420 range. These scenario estimates are grounded in market-cap math and past cycle behavior.

My view is supported by growing on-chain and institutional signals: Ethereum’s total value locked (TVL) recently topped $90 billion, institutional interest is accelerating, and spot Ether ETFs recorded a $1.01 billion net inflow in a single day. Major market voices — including Tom Lee, Arthur Hayes, and Joe Burnett — are also forecasting substantial upside for Bitcoin, with several predicting BTC above $150K this year or into 2025.

With ETH trading near $4,630 — only about 5.35% below its November 2021 all-time high of $4,878 — I don’t expect a significant cooldown until Ethereum reclaims that level. Traders I follow, like Michaël van de Poppe, anticipate a fresh all-time high for Ether followed by a period of consolidation. Given these on-chain metrics, ETF demand, and possible BTC-led tailwinds, I remain optimistic on Ethereum’s upside potential.
