ETHFI: ether.fi Perps

ETHFI is a perpetual futures contract on Polymarket that tracks the price of ether.fi (ETHFI). It lets you go long or short on ETHFI using pUSD as collateral, with no expiry date, so you can hold your position as long as you want. Right now, ETHFI is trading at $0.67, down 9.77% in the last 24 hours.

You can trade ETHFI with up to 5x leverage on Polymarket. The default margin mode is Isolated. For example, with 5x leverage and a $1,000 position, you're controlling $5,000.00 worth of ETHFI. Higher leverage amplifies both gains and losses, and at current settings, a 5x long position would have a liquidation price around $0.59.

ETHFI uses two prices. The oracle price (0.6673) reflects ether.fi's real-time spot price from external data feeds. The mark price (0.66679) is Polymarket's calculated fair value used for P&L and liquidations. Right now, the spread between mark and oracle is just $0.00 (0.08%), which means the contract is tracking ETHFI's spot price very closely. A funding rate of 0.0013% is applied every funding cycle to keep these prices aligned.

The current funding rate for ETHFI is 0.0013%, resetting in the next funding cycle.

Funding rates are dynamic and update each cycle, so check this page for the latest rate.

The mark price (0.66679) is Polymarket's calculated price used to determine your unrealized P&L and liquidation thresholds, and it's what matters for your position. The oracle price (0.6673) is the external reference price pulled from real-time ether.fi spot price data. When these two are close (currently within 0.08%), it means the market is efficiently priced with minimal premium or discount.

Beyond ETHFI, Polymarket offers perpetuals on other popular Crypto assets including BTC, ETH và SOL. Each contract works the same way: pUSD-settled, no expiry, with leverage up to 5x.

Polymarket perpetuals supports both Cross Margin and Isolated Margin. Cross Margin shares collateral across all open positions, which can help prevent liquidation, but may put more of your balance at risk. Isolated Margin assigns collateral to each position individually, so only the funds allocated to that position are at risk of liquidation.

Through its partnership with TradingView, Polymarket brings advanced charts, indicators, drawing tools, and multiple timeframes directly to each Perps asset page. TradingView provides charting technology for traders to review price action and prepare trades using symbols such as ETHUSD and BTCUSD charts, among others.
