Tether, the dollar-pegged stablecoin, has overtaken Ether ($ETH) by market capitalization as ETH fell to $1,500 — a price last seen in October 2023 and revisited in April 2025. The flip puts a fixed-value instrument above Ethereum's native asset in the rankings, a milestone that measures the depth of this decline more than it reveals anything about Tether's own growth.
What the Flip Actually Signals
A stablecoin surpassing a variable-price asset in market cap is a price-fall story, not a Tether achievement story. Tether is engineered to hold a value near one U.S. dollar; its market cap is roughly a function of how many dollars are locked into it. ETH's market cap, by contrast, moves directly with price. When ETH drops far enough, the math tips the ranking automatically.
The first question any markets reporter asks is: who was selling ETH, and who was on the other side? Rotation into dollar-denominated instruments — stablecoins being the most direct on-chain route — is a common pattern in crypto selloffs. The source does not provide on-chain flow data to confirm that mechanism here, so the causality stays circumstantial.
The $1,500 Level: Support That Has Held Twice Before
Ether's current price of $1,500 represents a return to what the source characterizes as crucial long-term support. That zone was last tested in October 2023 and again in April 2025. The source does not specify whether volume or buyer conviction at this level resembles either prior visit — price alone does not tell that story.
Ranking Shift as a Downturn Benchmark
Until this rout, Ether held a higher market cap than Tether. Being overtaken now by a token designed not to appreciate in price is a clean, unarguable benchmark for how far $ETH has fallen. The source provides no forward guidance or on-chain metrics; what it records is where the line crossed — and the two prior moments in time when prices were last this low.
