Bitfinex ETH longs climb to their highest level in over four years

Margin traders on Bitfinex are leaning hard into Ethereum. Long positions on the exchange have reached their highest level in more than four years.

As of October 11, 2026, Bitfinex margin data showed approximately 283,410 ETH in longs. That works out to roughly $709 million at current prices, the largest bullish bet on the platform since at least 2022.

The numbers behind the bet

A margin long is a leveraged wager that a price will rise. A trader borrows funds, buys more of an asset than they could afford outright, and profits if the price goes up.

Bitfinex longs sat at around 82,500 ETH in late August. The jump to more than 283,000 ETH since then is substantial, and much of it happened quickly.

Long positions surged 157% over just seven days, according to the margin data. The current tally sits just below the 90-day peak of 283,598 ETH, recorded on October 8.

Shorts tell the opposite story. Bets against ETH on Bitfinex have dwindled to approximately 3,530 ETH, or about $8.8 million.

Put the two figures side by side and you get a long-to-short ratio of roughly 80:1.

The buildup arrived while Ethereum traded around $2,500. It also came after a stretch of price volatility that included a recent dip, which suggests some traders treated the weakness as an entry point.

A sharp reversal from September

The current setup looks very different from a few weeks ago. In late September 2026, short positions on Bitfinex spiked to a four-year high, landing somewhere between 73,000 and 101,000 ETH.

Those shorts then fell away sharply. Today’s figure of roughly 3,530 ETH is a small fraction of that late-September peak.

Commentary on X has framed the long buildup as a sign of conviction among large “whale” traders on the platform.

What this means for ETH traders

The imbalance has sparked talk of a potential short squeeze. A squeeze happens when rising prices force short sellers to buy back the asset to close losing positions, and that buying pushes prices even higher.

With shorts at approximately $8.8 million against roughly $709 million in longs, there is relatively little short interest on Bitfinex left to squeeze. The fuel for that particular fire has mostly burned off already, likely during the late-September unwind.

When longs dominate this heavily, the bigger risk may be a long squeeze, where a price drop triggers forced selling from leveraged bulls and accelerates the decline.

For anyone tracking Ethereum, watch whether longs push past the October 8 peak of 283,598 ETH, which would suggest continued accumulation. Watch the short side as well, as a rebuild in short positions from today’s low base would signal that skeptics are returning. Finally, watch how ETH behaves around the $2,500 area where much of this buildup took place.
