Ethena begins backing USDe with tokenized stocks via Binance basis trade
Ethena has begun backing its USDe synthetic dollar with tokenized equities for the first time, buying Binance’s bStocks and shorting matching equity perpetuals to collect funding payments from leveraged longs. The move extends a hedging strategy that already underwrites $4.9 billion of USDe with crypto into a stock market Ethena says dwarfs the $15 billion crypto perpetual pool it captured last cycle.
- Ethena will hold Binance bStocks in Nvidia, Tesla and SpaceX among 17 qualifying equity pairs.
- Binance’s equity basis trade has averaged about 11% annualized over the past six months, per Ethena.
- Binance handled 76% of the $250 billion in equity perpetual volume traded in July, per CryptoQuant.
- 11% Binance’s average annualized equity basis over six months
- 76% Binance’s share of July’s $250 billion equity perpetual volume
- $4.9B USDe backed with crypto since launch
Ethena began the trade on Friday, September 25, 2026, buying Binance’s bStocks and shorting the exchange’s matching equity perpetuals to earn the funding leveraged longs pay, first reported by CryptoPotato. The structure mirrors the delta-neutral trade Ethena has run on Bitcoin, Ether and Solana since launch, only now the spot leg is a share-backed token rather than a cryptocurrency.
Ethena called the tie-up “one of the most exciting updates to the USDe collateral backing since launch” in a post on X. It is the first time the protocol has widened its collateral base beyond crypto since it added Bitcoin to USDe’s backing in April 2024, when supply stood at $2 billion versus $4.9 billion today.
Binance’s bStocks Are Backed One-for-One by Custodied Shares
The spot leg of the trade is a bStock, issued by Binance affiliate BTech Holdings Limited and backed one-for-one by custodied shares of the underlying company. Binance gives eligible delta-neutral accounts, including Ethena’s, lower priority in auto-deleveraging, a protection that matters when funding-driven strategies need to hold positions through volatility.
The scale Ethena is chasing is already concentrated on one venue. CryptoQuant data shows Binance handled 76% of the $250 billion in equity perpetual volume traded in July, while its tokenized U.S. equities reached $100 million in assets within two weeks of their June launch.
Kairos Research Framework Clears 17 of Binance’s 67 Pairs
The allocation follows a framework Kairos Research wrote for the Ethena Risk Committee. A name qualifies on $25 million of perpetual open interest over 14 days, 30 days of funding history, and a matching tokenized stock listed on the same venue.
Seventeen of Binance’s 67 stock-perpetual pairs passed, Nvidia, Tesla and SpaceX among them, on a venue holding $2.14 billion of the $2.9 billion measured across four exchanges. Carry on the approved Binance names had halved in a month to about 7%, with two names negative.
Earnings season is the stated stress test. Across 37 earnings events, the underlying stocks gapped 9.9% on average while the hedged position moved just 20.3 basis points, a gap the framework used to justify inclusion.
The report still made bStock approval conditional on a side letter with the issuer, since holders have no proprietary interest in the backing shares and every bStock contract sits behind a single upgrade key.
Ethena Says Equity Perpetuals Dwarf Its $15 Billion Crypto Base
“We expect the market opportunity size for equity perpetuals to far exceed the $15b+ of crypto perpetuals captured by Ethena last cycle,” the protocol wrote in its announcement. USDe’s own trajectory shows how much room that leaves: supply peaked at $14.8 billion on October 4, 2025, according to DefiLlama, before contracting to the $4.9 billion it stands at now.
ENA traded at $0.24 on Friday, up 12% in 24 hours, per CoinGecko. The rally came the same day Ethena unveiled the Binance partnership.
The CCS read. Concentrating both the collateral and the hedge on a single exchange ties USDe’s stability to Binance’s solvency and its single upgrade key in a way crypto collateral never did. For ENA holders and stablecoin allocators, the 11% carry compressing to 7% within a month is the more telling number than the headline market size Ethena is chasing.
Ethena has not said when it will extend the equity basis trade beyond Binance, leaving the Kairos Research framework as the template for any second venue. The next test comes with the following earnings season, when the 37-event sample of 9.9% stock gaps against 20.3 basis point hed
