Tom Lee Explains Ethereum's Killer Application as ETH Bucks Market Downturn

Fundstrat co-founder Tom Lee says Ethereum (ETH) is becoming the settlement layer for Wall Street and artificial intelligence (AI). He repeated the claim as ETH held up better than most major cryptocurrencies over the past week.

Lee, who chairs BitMine Immersion Technologies (BMNR), made the comment in a reply on X. A trader had asked why Ethereum was outperforming nearly every other top ten coin during a broader crypto pullback.

The Wall Street and AI Thesis

Asked directly why Ethereum was holding its ground, Lee pointed to the network’s emerging role as financial plumbing.

“$ETH is the future settlement rails for Wall Street and AI.”

The reply echoes arguments from Lee’s bullish crypto outlook for the next 12 months. He ties Ethereum’s case to two forces, Wall Street’s tokenization of traditional assets and the rise of agentic AI. Agentic AI refers to autonomous software that can transact without human input.

Lee has also framed the recent ETH/BTC ratio breakout as evidence the market is pricing in that shift. BitMine has backed the thesis with purchases, pushing toward a 5% ether stake. The position still sits underwater on a cost basis.

Whether this reflects Lee’s thesis taking hold, or just short-term positioning, remains unclear. The answer may come clearer if Ethereum’s outperformance extends as other coins dip.

Ether Holds Up While Rivals Slip

Ether was among the few top-ten assets to trade higher over the past seven days. Tron (TRX) was the only other gainer, with stablecoins excluded. Bitcoin (BTC), BNB, XRP, Solana (SOL), Zcash (ZEC), and Hyperliquid (HYPE) all posted weekly losses, several exceeding 3%.

Ether changed hands around $2,518 on Monday, down roughly 0.1% over 24 hours. Bitcoin traded near $77,100, off more than 1.5% for the day.
