Binance has expanded its margin trading collateral options by adding five bStocks tokenized securities to Cross Margin, Portfolio Margin, and Portfolio Margin Pro. The new assets, effective October 21, 2026, at 12:00 UTC, include RoboStrategy Inc (BOTB), Berkshire Hathaway (BRKBB), KraneShares STAR Market 50 ETF (KSTRB), Direxion Daily 20 Year Treasury Bull 3X ETF (TMFB), and Vistra Corp (VSTB). While these tokens can now serve as collateral for margin positions, borrowing against them is not currently supported. Eligible users in permitted jurisdictions must complete a suitability assessment questionnaire before utilizing bStocks-related margin features. Binance emphasizes that bStocks are offered through an Approved Prospectus in the Abu Dhabi Global Market (ADGM) and are not available in other regions, including the United States.
