Prediction market Polymarket now puts the odds of Ethereum losing its No. 2 crypto market-cap ranking before 2027 at 61%, up sharply from 17% at the start of 2026. For an asset that has held second place for nearly a decade, that shift is notable. Market sentiment around ETH has changed fast.
The gap with USDT is not as wide as it appears
According to the figures cited in the report, ETH is trading around $2,049 with a market capitalization of roughly $247.35 billion, while Tether stands at $184.07 billion. The difference still looks sizable, but the math is more uncomfortable for Ethereum than the headline number suggests: if ETH falls to about $1,525, a decline of roughly 25% from current levels, USDT would overtake it.
This is not a purely hypothetical scenario. ETH dropped to $1,746 in February during a broader crypto selloff tied to US-Israel-Iran war tensions, marking its lowest level since April 2025. The article also notes that ETH broke below $2,000 again on Friday, is down 30% over the last 60 days, and still sits 57% below its August 2025 all-time high.
ETF outflows and DeFi deleveraging are weighing on ETH
Glassnode data cited in the story shows that US spot Ethereum ETF assets under management have fallen 65% since October 2025, shrinking from $31.86 billion to about $11.76 billion. That withdrawal of capital has been paired with a structural weakness: ETH remains the main collateral and leverage asset across crypto, so it tends to be sold early and aggressively when markets move into risk-off mode.
On-chain activity reflects that pressure. Tens of thousands of ETH were reportedly sold in recent months to repay Aave loans, reinforcing a loop in which falling prices triggered more selling to avoid liquidation. The article also references Anthony Scaramucci’s view that institutions have largely chosen Bitcoin, not Ethereum, as the default destination for new allocations.
USDT leads the challengers, while XRP, BNB, and SOL build ground
Among the contenders, USDT is framed as the most immediate threat. Its market cap has expanded from $73 billion in 2021 to $184 billion today, and that growth does not depend on token price appreciation. Stablecoins tend to benefit when traders rotate toward safety. On March 24, Tether also hired KPMG for its first full independent audit, a move the report says could improve its institutional standing.
Other large-cap rivals are also making their case. BNB is listed at about $84.06 billion, with the Maxwell upgrade improving scalability. XRP stands at roughly $82.52 billion, supported in the article by ETF inflows, institutional adoption, and a possible CLARITY Act catalyst. Solana, at $48.08 billion, has surpassed Ethereum in transaction volume and, for the first time in March, moved ahead on RWA holders. Its Alpenglow upgrade targets 150ms block finality, which would make it one of the fastest major Layer 1 networks if delivered as described.
For now, only USDT is presented as being within realistic striking distance. The report’s central point is simple: the $63 billion gap between Ethereum and Tether is the narrowest it has been in years, and the current macro setup is favorable to stablecoins rather than leveraged crypto beta.
