Ethereum (ETH) is facing growing risk of losing its position as the second-largest cryptocurrency by market capitalization.

Polymarket bettors predict a 57% chance that Ethereum could be “flipped” and fall from second place by year-end, up from just 14% in January, signaling rapidly shifting market sentiment.

The stablecoin giant Tether (USDT) is now the primary contender poised to overtake Ethereum’s market position.

Since its 2015 launch, Ethereum has maintained near-ironclad control of the second spot, though challenges have occasionally emerged.

During the 2017 ICO boom, Ethereum’s market capitalization reached approximately 30% of the total crypto market, briefly narrowing the gap with Bitcoin and fueling “flippening” hype.

Ethereum has also slipped below second place during past altcoin volatility. In 2018, XRP temporarily overtook Ethereum multiple times, demonstrating how market dynamics can disrupt rankings.

Currently, the biggest threat comes from Tether’s explosive growth, with the fiat-pegged stablecoin reaching a valuation of $184 billion.

Analysts suggest that if liquidity and stability outweigh decentralized computation, Ethereum could see its dominance challenged, particularly amid ongoing bear market conditions.

Market observers are closely watching whether Tether can maintain momentum and secure the coveted second position, signaling a potential shift in cryptocurrency rankings.
