Ethena Labs has launched its first equity basis-trading strategy on Binance to back its $4.9 billion USDe synthetic dollar. By holding Binance's tokenized bStocks as spot collateral and hedging with USDT-denominated equity perpetual futures, Ethena extends its delta-neutral model beyond crypto. The move is driven by declining crypto funding rates, with bitcoin yields dropping to 2.2% in 2026. Following the announcement on 25 September 2026, Ethena's ENA token surged 12% to $0.249.
Launch of equity basis-trading strategy
- ▪On 25 September 2026, Ethena Labs announced a partnership with Binance to back its USDe synthetic dollar with tokenized U.S. stocks, holding Binance's tokenized stock product, bStocks, as spot collateral.
- ▪Ethena Labs' equity basis-trading strategy on Binance expands its potential underlying collateral pool from approximately $2.5 trillion in crypto assets to over $150 trillion in real-world assets
- ▪Ethena Labs began allocating capital to its new equity basis-trading strategy on Binance on 25 September 2026.
Delta-neutral strategy and risk mitigation
- ▪Ethena Labs' Risk Committee identified off-hours trading as a structural risk, as U.S. stock markets close while tokenized stocks and perpetuals continue trading.
- ▪Binance provides lower auto-deleveraging priority for eligible delta-neutral accounts, including those of Ethena Labs, reducing liquidation risks during market stress.
- ▪Ethena Labs' delta-neutral strategy hedges spot tokenized stock positions by shorting Binance's USDT-denominated equity perpetual futures to capture the price difference and funding payments.
Comparison of crypto and equity funding rates
- ▪Binance's equity perpetual contracts averaged annualized funding rates of 17.5% from 20 May 2026 to 11 August 2026, compared to lower crypto yields such as bitcoin's 2.2% annualized rate in 2026
- ▪Ethena Labs expanded into equities because crypto funding rates declined, with weighted bitcoin funding rates falling from an 11.0% annualized average in 2024 to 2.2% in 2026 through 11 August 2026.
Impact on ENA token price
- ▪The ENA token price surge following Ethena's Binance equity integration announcement was accompanied by the forced liquidation of approximately $150,000 worth of ENA short positions
- ▪Following the Binance integration announcement, the Ethena (ENA) token price increased by 12% within 24 hours, reaching approximately $0.249 on 25 September 2026.
Binance bStocks market and structure
- ▪Binance bStocks are issued by BTech Holdings Limited and represent an interest in underlying shares held by the issuer, rather than direct stock ownership.
- ▪The tokenized stock market tracked by Token Terminal grew to $2.7 billion in August 2026, with Binance bStocks accounting for over $600 million.
Growth of Binance equity perpetuals
- ▪Binance's traditional finance perpetual futures generated approximately $433.4 billion in trading volume during August 2026, with equity-linked contracts accounting for $342.9 billion.
- ▪Open interest in Binance's equity perpetual contracts exceeded $2.9 billion and grew at a compound monthly rate of 105% in 2026.
Kairos Research analysis and recommendations
- ▪Kairos Research recommended that Ethena Labs approve bStocks only after establishing a side letter restricting what the issuer can do with the backing shares.
- ▪Kairos Research reported that approved Binance equity names averaged approximately 18% annualized returns in late July 2026 and about 7% as of 26 August 2026.
Debatable claims
- ▪Using bStocks as collateral exposes USDe to excessive counterparty risk
- ▪Ethena's equity basis-trading strategy poses unacceptable risks to USDe
- ▪Binance's preferential auto-deleveraging treatment for delta-neutral accounts is unfair
- ▪Synthetic stablecoins must expand into traditional assets to remain viable
