Tether, the dollar-pegged stablecoin, has surpassed Ether in market capitalization as $ETH prices fall to the $1,500 level — a threshold the asset last visited in October 2023 and again in April 2025. The milestone reshuffles the market-cap rankings at a moment when Ether is back at what chart-watchers have historically treated as long-term support.
What the Flip Actually Measures
State the mechanism before the narrative: Tether did not surge. Ether fell. A stablecoin's market cap is a near-fixed number — it reflects outstanding tokens priced at a dollar. Ether's market cap is price multiplied by circulating supply, which compresses quickly when the price routes. When a fixed-price instrument overtakes a floating one at a moment like this, the story is entirely in the floating one's column.
That is the frame for reading this flip. It is a ratio, and only one side of it moved.
A Support Level With a Track Record
$ETH is now back at a price it touched at two prior points in the cycle: October 2023 and April 2025. In both instances the level held, at least temporarily — which is why it earns the label "crucial long-term support" rather than just a round number. Support levels are not gravity; they are concentrations of historical buying interest. Whether that interest materializes again is the operative question, and nothing in the current data answers it.
The Harder Question
The Tether flip is a legible headline because it involves a named, familiar instrument crossing a ranked position. What it does not tell you is who was selling Ether on the way down, at what size, and whether that supply is now exhausted or merely paused. Those are the variables that determine whether $1,500 is a floor or a waypoint.
Two prior visits to this level gave bulls a case. The third visit inherits that framing, but markets do not owe a support level a third bounce simply because it delivered two. The mechanism — sustained selling pressure sufficient to hand a stablecoin a higher market cap than a major smart-contract platform — is the fact worth watching, not the ranking itself.
