Is Ethereum about to get flipped?

Tether's $USDT is inching toward a milestone that would have seemed far-fetched just a year ago: overtaking @ethereum to claim the number two spot in crypto by market cap.

As of June 5, 2026, Tether's market cap sits at approximately $187.4 billion, while $ETH trades just above $1,600. The gap between the two assets has narrowed to somewhere in the $6 to $10 billion range, making the margin thin enough to watch closely.

The Math Behind a Potential Flip

The arithmetic is straightforward. With Ethereum's price hovering just north of $1,600, a drop to roughly $1,550 would be enough to compress $ETH's market cap below Tether's current level. ETH is already down around 25% against the dollar over the past 30 days, which is the kind of sustained pressure that makes such a scenario credible rather than theoretical.

The flip could also come from the other direction. @tether does not need $ETH to fall; it can mint its way to second place. USDT's circulating supply has recently climbed to approximately $189.7 billion, maintaining roughly 60 percent of the stablecoin market. Every new batch of tokens minted by @tether increases that market cap by an equivalent dollar amount, with no dependence on price action.

Tether's Steady Climb

The backdrop to this story is a stablecoin sector that has grown rapidly. A year ago, Tether held a market cap of around $144.2 billion, representing a roughly 27.6 percent increase over the past twelve months. That growth has been largely immune to the broader market volatility that has weighed on assets like $ETH.

Tether posted approximately $1.04 billion in net profit for Q1 2026, with its excess reserve buffer reaching an all-time high of $8.23 billion and total assets of around $192 billion against USDT liabilities. That financial cushion gives the company considerable room to expand supply further if demand continues to grow.

Whether the flip happens through a further decline in $ETH, continued minting by @tether, or a combination of both, the gap is now small enough that markets are paying attention.
