In late February 2026, Jane Street, one of the world’s leading quantitative trading firms, suddenly found itself at the center of the crypto market spotlight. On February 24, the bankruptcy administrator for Terraform Labs filed an insider trading lawsuit against Jane Street in federal court in New York, alleging the firm engaged in front-running trades using non-public information during the 2022 Terra collapse. Soon after, a theory that had circulated in the crypto community for months—the "Bitcoin 10 a.m. daily dump"—quickly gained traction following the lawsuit’s disclosure. Market participants noticed that the persistent sell pressure at this specific time window, which had existed for months, "mysteriously" vanished once the lawsuit became public, and the Bitcoin price promptly staged a significant rebound. This chain of events thrust the secretive quant giant into the center of market manipulation suspicions.
Aftermath of the Terra Collapse: Lawsuit Timeline and Key Allegations
The turmoil began with a federal lawsuit targeting Jane Street. According to the complaint, Jane Street established a secret communication channel called "Bryce’s Secret" through Bryce Pratt, a former intern at Terraform Labs who later joined Jane Street. The core allegation is that on May 7, 2022, less than 10 minutes after Terraform Labs withdrew 150 million UST from the Curve liquidity pool without publicly disclosing its intentions, an address linked to Jane Street followed suit by withdrawing about 85 million UST.
The lawsuit claims that Jane Street used this non-public information to execute "front-running" trades before UST depegged and before the market-wide panic set in. As a result, the firm avoided over $200 million in potential losses and accelerated the collapse of $40 billion in Terra ecosystem market value. In response, a Jane Street spokesperson issued a strong rebuttal, calling the lawsuit "a desperate money grab" and stating the firm would vigorously defend itself, describing the allegations as "baseless and opportunistic."
It’s worth noting this isn’t Jane Street’s first encounter with regulatory scrutiny. In 2025, India’s market regulator SEBI accused the firm of manipulating the Bank Nifty index through a "pump in the open, dump midday" strategy, freezing approximately $565 million of its assets. This precedent has fueled skepticism about Jane Street’s conduct in the crypto space.
Data and Market Structure Analysis: Is the "10 a.m. Dump" Real or an Illusion?
As the lawsuit gained attention, the crypto community began linking Jane Street to the unusual Bitcoin sell-offs seen around 10:00 a.m. Eastern Time (right after the U.S. stock market opens) over the preceding months. An X account called "Whale Factor" pointed out that since November 2024, Bitcoin frequently dropped 2%–3% within minutes after the U.S. market open, speculating this was connected to Jane Street’s role as one of the largest authorized participants (APs) for BlackRock’s IBIT ETF. Supporters argue that after the lawsuit news broke, this pattern immediately stopped, and Bitcoin surged about 10% in a single day—an indirect piece of "evidence."
However, this popular narrative faces strong rebuttal from the data. Vetle Lunde, Head of Research at K33 Research, published an analysis showing that between January 2025 and February 2026, Bitcoin’s average minute return at 10:00 a.m. actually ranked in the top 25% for the entire day. He further explained that Bitcoin’s volatility peaks typically occur around the release of U.S. macroeconomic data and just before and after the U.S. market opens (09:31–09:37), a result of market microstructure and close correlation with U.S. equities, rather than targeted manipulation at a specific time.
Economist Alex Krüger shares a similar view. His analysis found that in the first 15 minutes of IBIT trading, Bitcoin drops about 1% on average, but then rebounds 0.9% over the next 30 minutes. He considers this "statistical noise," noting that these time windows closely track the NASDAQ index, indicating Bitcoin’s moves are part of a broader risk asset trend. Dragonfly partner Rob Hadick went further, calling the debate "somewhat silly," and noting that an AP’s daily job is to keep ETF prices in line with net asset value through buying and selling. These hedging activities are concentrated during high-liquidity periods and are often misinterpreted as targeted price suppression.
Breaking Down Market Sentiment
The event has split market opinion into two distinct camps:
On one side are the "manipulation skeptics," mainly on-chain analysts and retail traders. They firmly believe there’s a causal link between the lawsuit’s disclosure and the disappearance of the "10 a.m. dump." Glassnode’s co-founder, via the Negentropic account, pointed out that the daily flash crashes stopped immediately after the lawsuit became public. They argue that Jane Street, as one of the few APs capable of physical creation and redemption, has both the ability and incentive to push spot prices lower, trigger liquidations, and accumulate at the bottom—or profit from undisclosed derivatives short positions.
On the other side are the "market structure defenders," primarily institutional professionals and economists. They emphasize that the accusations stem from a misunderstanding of ETF market-making mechanics. Bitwise advisor Jeff Park explained that APs are exempt from immediate Bitcoin buying and selling when creating or redeeming shares, leaving a "gray window" for hedging and arbitrage. Ryan McMillin of Merkle Tree Capital added that APs tend to use futures for hedging. When futures trade at a premium, this arbitrage caps spot price rallies and amplifies declines when positions are closed—often misread by retail as "whale dumping."
Examining the Narrative’s Credibility
In this debate, it’s essential to strictly distinguish between facts, opinions, and speculation.
The facts: Terraform’s bankruptcy administrator has filed an insider trading lawsuit against Jane Street, alleging it traded on non-public information in 2022. Jane Street denies the charges. Meanwhile, Bitcoin did experience frequent declines around 10 a.m. during certain periods.
The opinions: Many market participants directly link these two events, believing Jane Street’s alleged manipulation caused the "10 a.m. dump."
The speculation: Some analysts suggest that Jane Street’s billions in Bitcoin ETF long positions disclosed in 13F filings may be offset by undisclosed off-exchange derivatives shorts, resulting in a net negative position—profiting from price declines. This remains logical inference without public evidence. As Rob Hadick noted, there’s no public proof Jane Street intentionally manipulated Bitcoin prices.
Industry Impact Assessment
Regardless of the lawsuit’s outcome, this incident has already had a profound impact on the industry. First, it’s significantly advanced market education, prompting investors to understand the complex mechanics of spot Bitcoin ETFs—especially the role of APs, the physical creation/redemption process, and how futures hedging can affect spot prices.
Second, the event has intensified scrutiny of major quant firms’ roles in the crypto market. Jane Street, as a key liquidity provider for Coinbase, a major shareholder in several crypto mining companies, and an investor in multiple leading DeFi projects, wields considerable influence. Widespread suspicions of market manipulation reflect the common search for a "scapegoat" during downturns, while also exposing the limitations of current disclosure frameworks (like 13F filings, which only show long positions).
Possible Future Scenarios
Looking ahead, this event could play out along three main paths:
Scenario 1: Intensified Regulatory and Legal Action. If the New York federal court lawsuit moves into substantive investigation, or if Indian or even rumored Chinese regulators make progress, Jane Street could face stricter compliance reviews, fines, or trading restrictions. This would force other quant giants to reassess their global market risk exposure and compliance costs, potentially putting short-term pressure on market liquidity.
Scenario 2: Narrative Cools, Macro Factors Regain Focus. If no hard evidence emerges to support the manipulation allegations and Bitcoin’s price action resumes tracking macro risk assets like the NASDAQ, the "10 a.m. dump" story will gradually fade. Investors will refocus on core macro drivers such as Fed policy and inflation data.
Scenario 3: Greater Industry Transparency. This controversy could catalyze regulatory reform. In the future, regulators may require major market makers to disclose more comprehensive risk exposures, including key derivatives hedges, enabling the market to better identify real capital flows and institutional intent.
As of February 27, 2026, according to Gate market data, after the event-driven Bitcoin rebound, market sentiment has become increasingly complex. The truth may still be hidden within the intricate ETF mechanisms and undisclosed derivatives books, but one thing is certain: understanding market microstructure has become essential knowledge for every market participant.
