Rumors that quant trading giant Jane Street systematically sells Bitcoin every day at 10 AM EST have spread across social media and legal filings. But multiple data points and market analyses suggest the narrative is flawed: the observed volatility is likely a natural feature of risk asset opening hours, not deliberate manipulation.
Lawsuit Sparks Conspiracy Theories
The controversy gained traction after a court-appointed manager sued Jane Street over alleged suspicious trading around the 2022 Terra collapse. As case details emerged, some crypto influencers linked Bitcoin's recent price drops to Jane Street. They pointed to Jane Street's large position in BlackRock's iShares Bitcoin Trust (IBIT), arguing the firm could use futures and options to build a net short position not fully disclosed in public filings. The theory evolved into a claim that Jane Street algorithmically sells Bitcoin spot or futures at 10 AM daily, then buys ETF shares at lower prices—a so-called "liquidity sweep" arbitrage loop.
Data Check: 10–10:30 AM Returns Are Positive
Macro analyst Alex Krüger back-tested Bitcoin performance in the 10:00–10:30 window since January 1. His finding: cumulative returns are actually positive, contradicting the "systematic dump" claim. Krüger noted that the window coincides with the U.S. stock market open, when risk assets naturally reprice—volatility is expected, not malicious. Bitcoin's high correlation with the Nasdaq Composite makes synchronized moves unsurprising. CryptoQuant research head Julio Moreno added that "buy spot, sell futures" delta-neutral strategies are arbitrage plays, not price suppression tools. Labeling them as deliberate market manipulation oversimplifies complex trading structures.
One Firm Can't Dominate a Global Asset
Bitcoin trades 24/7 across borders with deep liquidity. While a large firm might amplify short-term volatility during specific hours, it cannot sustainably control the overall trend. Coin Bureau co-founder Nick Puckrin emphasized that Bitcoin is not a meme coin; its price formation involves global exchanges, derivatives markets, and on-chain liquidity. Attributing price declines to a single company ignores macro factors and misleads investors. He pointed to geopolitical risks, global liquidity tightening, and capital flows into AI as more plausible drivers of Bitcoin's recent weakness.
