The B-side of bStocks: Using Perpetuals Rather Than Spot Trading to Compete for Post-Market Price Discovery
- Binance's stock perpetuals (Perp) and bStocks products aim to capture price discovery power during times when traditional stock markets are closed, rather than simply extending trading hours.
- On weekends when U.S. markets are closed, Binance's stock Perps show significant trading volumes (e.g., $461 million combined for NVDA, TSLA, SNDK, SKHY in August 2026) but sometimes misprice the Monday opening, indicating volume alone does not guarantee pricing accuracy.
- The proposed market structure uses Perp as the primary price discovery engine for directional views and leverage, while bStocks serves as an inventory and correction layer, with Direct Stock handling traditional market interfaces.
- Historical parallel: Chicago Board of Trade's 1848-1865 development of standardized grain grading and warehousing created conditions for liquid futures markets by establishing uniform standards and reducing transaction costs.
- The competitive advantage lies not in offering two extra trading days, but in absorbing capital revaluation of stocks during market closures (weekends, holidays) when news and macro events continue to occur outside official exchange hours.
Binance's approach to 24/7 stock trading is not about simply extending market hours, but about establishing a new market structure to capture pricing power during traditional market closures. The article examines how perpetual futures, bStocks, and Direct Stock products work together: Perp absorbs trading direction and leverage with lower barriers to entry, bStocks provides on-chain inventory that can be held and collateralized, and Direct Stock maintains traditional market interfaces. This structure allows the market to process price discovery when NYSE, Nasdaq, and other exchanges are closed.
The evidence suggests volume alone does not guarantee accurate price discovery. In August 2026, Binance's stock Perps on SNDK traded $338 million over a weekend, pricing the stock at $1,223.98 on Sunday, but the Monday cash market opened at $1,203.41—a directional miss despite massive volume. Conversely, during the July 4th holiday, Binance's Perp pricing of SNDK at $1,841.88 on Sunday proved prescient when the Monday open was $1,828.68, capturing a 4.8% gap. This inconsistency reveals that the market structure, not just trading volume, determines pricing accuracy.
The article draws a historical parallel to the Chicago Board of Trade's development in the 19th century. When CBOT standardized grain grading and warehousing (1859-1865), it reduced transaction costs and created conditions for liquid futures markets. Similarly, Binance's structure uses Perp as the primary price discovery engine—since derivatives have lower costs for expressing views than spot markets—while bStocks serves as the inventory and correction layer. The goal is not to compete with Nasdaq directly, but to establish an alternative market that can absorb capital revaluation during closures, positioning Binance to influence the official price when traditional markets reopen.
bStocks的B面：用永续合约而非现货交易争夺盘后定价权
币安对24/7股票交易的理解不是简单延长交易时间,而是建立新的市场结构以在传统市场休市期间争夺定价权。该文章分析了永续合约、bStocks和Direct Stock产品如何协同运作:Perp以较低的进入壁垒吸收交易方向和杠杆,bStocks提供可持有和抵押的链上库存,Direct Stock维持传统市场接口。这种结构使市场能在纽交所、纳斯达克等交易所休市时进行价格发现。
证据表明,交易量本身不能保证准确的价格发现。2026年8月,币安SNDK股票永续合约周末交易3.38亿美元,周日价格达$1,223.98,但周一现货市场开盘价为$1,203.41——尽管交易量巨大但方向错误。相反,7月4日假期期间,币安永续合约对SNDK的$1,841.88定价在周一开盘$1,828.68时被证实正确,捕捉了4.8%的跳空。这种不一致性表明市场结构而非仅交易量决定定价准确性。
该文章借鉴了19世纪芝加哥期货交易所的历史发展。当CBOT标准化粮食分级和仓储(1859-1865年)时,它降低了交易成本并为流动性期货市场创造条件。类似地,币安的结构以Perp作为主要价格发现引擎——因为衍生品表达观点的成本低于现货市场——而bStocks作为库存和修正层。目标不是直接与纳斯达克竞争,而是建立能在休市期间吸收资本重新估值的替代市场,使币安在传统市场重新开盘时能影响官方价格。
