Jane Street最新提交的13F文件显示,截至2026年6月30日,这家量化交易公司申报的美国比特币现货ETF份额总值已超过10亿美元。其中,贝莱德旗下 IBIT 是其最大单一持仓,申报价值约为8.28亿美元。

这份文件反映的是季末时点持仓,而不是 Jane Street 当前仓位。由于13F只披露可申报证券的多头持仓,不包含空头头寸和多数衍生品,因此外界无法仅凭这份文件判断该公司对比特币的实际净敞口。

IBIT持仓较上季回升

按披露数据计算,Jane Street 在第二季度对 IBIT 的申报持仓较前一季度明显增加。此前截至3月31日,公司申报约590万份 IBIT,价值约2.25亿美元;到6月30日,这一部分已升至约8.28亿美元。

除 IBIT 外,Jane Street 还持有其他在美国上市的比特币现货 ETF,包括富达的 Wise Origin Bitcoin Fund,以及灰度的 Bitcoin Trust。合并计算后,其已披露的相关 ETF 份额在季末超过10亿美元。

13F无法反映净敞口

13F是美国证监会要求合格机构管理人定期提交的持仓文件,主要披露可申报证券的数量和季末市值。ETF份额属于这一披露范围,因此市场可以看到 Jane Street 在6月30日持有的部分多头仓位。

但这类文件并不能展示完整交易账本。空头交易不会出现在13F中,多数衍生品也不会被纳入。即便部分看跌或看涨期权需要单独申报,外界仍无法据此还原这些仓位与其他交易之间的对冲关系。

因此,这份文件只能说明 Jane Street 在季末申报的比特币现货 ETF 多头份额超过10亿美元,不能等同于其直接持有等值比特币,也不能据此认定其持有未对冲的同等规模风险敞口。

机构继续借道ETF参与市场

这份披露再次显示,大型金融机构仍在通过美国合规比特币基金进行交易、配置和流动性管理。作为交易型产品的重要做市与量化交易参与者,Jane Street 的相关持仓也可能服务于做市、套利、对冲等策略,而不一定代表长期方向性押注。

此前,IBIT 已多次在机构披露文件中成为最大加密基金持仓之一。其他金融机构也通过相同渠道披露过相关仓位,例如巴克莱曾在更早的文件中申报约1.31亿美元相关敞口。

报道提到,目前没有证据显示比特币或相关 ETF 价格对这份文件出现了单独、明确的市场反应。价格走势通常还会同时受到资金流、宏观消息和整体仓位变化影响。

下一份文件看9月30日

Jane Street 下一份13F文件将对应9月30日的可申报持仓快照。按美国证监会安排,2026年第三季度报告截止日期为11月16日。
