By the end of February 2026, the crypto market is shrouded in a strange “coincidence.” Over the past few months, Bitcoin has often experienced a precise wave of sell-offs at 10 a.m. Eastern Time, dubbed by the market as the “Jane Street 10 a.m. dump strategy.” However, just this week, with a lawsuit filed in the U.S. Federal Court in New York, this mechanically precise selling pressure suddenly vanished, and Bitcoin along with numerous altcoins surged.
This is not an urban legend but a real turmoil faced by Wall Street’s top quant giant, Jane Street. As one of the most secretive and profitable trading firms globally, Jane Street was previously fined heavily for alleged manipulation in the Indian derivatives market last year and is now entangled in the old case of TerraUSD (UST) collapse in 2022. Todd Snyder, the bankruptcy trustee of Terraform Labs, has officially filed suit, accusing Jane Street of front-running trades using insider information, accelerating the destruction of a crypto empire once valued at $40 billion.
When “delayed justice” strikes precisely after four years, and traditional financial quant giants leave indelible on-chain evidence in the decentralized world, we must reconsider a core issue: Is the “black box” operation of centralized giants like Jane Street fueling market liquidity or amplifying systemic risk?
To understand the destructive power of this lawsuit, we need to rewind to May 7, 2022 — the pivotal moment that triggered a seismic shock in the crypto industry.
In the design of the algorithmic stablecoin UST, the Curve liquidity pool (especially Curve 3pool) was central to maintaining its dollar peg. According to court documents disclosed by the bankruptcy trustee, on that day, Terraform Labs quietly withdrew 150 million UST from the Curve pool without any public announcement. For a highly confidence-dependent and liquidity-sensitive stablecoin, such a withdrawal was extremely dangerous.
Shockingly, just ten minutes later, a wallet address allegedly linked to Jane Street urgently withdrew 85 million UST from the same pool. Under the AMM (Automated Market Maker) mechanism, such an extreme tilt in pool assets can trigger exponential slippage. Jane Street’s withdrawal of 85 million UST was like detonating a directional bomb on a dam already showing cracks, directly causing UST liquidity to dry up and initiating the subsequent “death spiral.”
This critical ten-minute window became irrefutable evidence of insider trading in the lawsuit. The complaint reveals a behind-the-scenes network called “Bryce’s Secret.” Jane Street is accused of deliberately assigning Bryce Pratt, a former intern at Terraform Labs, to leverage personal connections to re-establish contact with Terraform’s software engineers and business development managers. This private chat group, composed of former colleagues, essentially became a backdoor for funneling major internal secrets of Terraform to Wall Street giants.
Moreover, the bankruptcy trustee, who previously filed a $4 billion claim against another quant giant Jump Trading, further alleges that some non-public information about Terraform Labs was leaked to Jane Street via Jump Trading. The covert communication among top-tier market makers on Wall Street during crises has left retail investors exposed to an extreme asymmetry of information.
Despite Jane Street’s spokesperson vehemently denying, calling it a “desperate and transparent extortion,” and blaming Do Kwon and Terraform’s management for billions of dollars in fraud, the immutable on-chain timestamps and recovered chat logs present an unprecedented legal backlash against the quant giant’s past “dimensionality reduction” tactics.
Jane Street’s case prompts a deeper industry reflection: Are the “black box” operations of centralized giants exacerbating systemic risks in crypto assets?
In traditional finance, Jane Street is known for its low profile and astonishing profitability. They rely on complex mathematical models, high-frequency trading (HFT), and ultra-low latency hardware to profit from tiny spreads. When such institutions began to heavily enter the crypto market around 2020, the industry naively believed they would bring much-needed liquidity and efficient pricing.
However, reality proved that profit-driven capital in the unregulated crypto space is more prone to become predatory trading. Crypto market depth still lags behind that of the US stock market by orders of magnitude. When funds of Jane Street’s scale and their algorithmic trading engines intervene, they are not just price takers but also price creators.
Take the recent widely discussed “10 a.m. dump strategy” as an example. Due to the operation mechanism of spot Bitcoin ETFs (like BlackRock’s IBIT), market makers need to align subscription/redemption with net asset value (NAV) at specific times.
Analysts suggest that, leveraging large holdings and algorithms, giants can exert selling pressure during periods of low liquidity, artificially induce panic sell-offs, trigger margin calls on retail leveraged longs, and then scoop up assets at lower prices. This strategy, often monitored closely by the SEC in traditional markets, remains ambiguous in the crypto spot market.
The Terra incident vividly demonstrated the power of “black box algorithms + information asymmetry.” When the system is stable, market makers provide liquidity; but when tail risks (like UST de-pegging) emerge, these giants’ algorithms can turn against the system instantly. With insider information or millisecond-level on-chain data perception, they do not provide buffers but instead become front-runners or capital withdrawers. This “sunny day umbrella, rainy day ladder” behavior, amplified by their vast funds, can rapidly turn localized liquidity crises into systemic collapses.
Broadening the perspective, Jane Street’s behavior in crypto is not an isolated case but an extension of its inherent trading logic.
In July 2025, India’s Securities and Exchange Board (SEBI) fined Jane Street a record 48.44 billion rupees (about $5.8 billion) and imposed trading bans. SEBI’s investigation revealed that during 18 options expiry days (including Bank Nifty and Nifty 50), Jane Street engaged in “short-term, large, and highly aggressive” intervention trades across spot, futures, and options markets. They exploited capital advantages at key expiry points to manipulate index levels, thereby securing huge profits from options positions.
Whether in India’s traditional derivatives markets or on-chain liquidity pools in Terra, the underlying behavior logic is consistent: identify market vulnerabilities (such as options expiry liquidity gaps or stablecoin pool imbalances), then leverage large capital and millisecond execution to conduct “highly aggressive” interventions.
The difference is that traditional markets have mature regulators (like SEBI) conducting post-event forensic reviews; in 2022’s crypto markets, giants mistakenly believed that decentralization could serve as a shield.
Now, nearly four years after Terra’s collapse and with Do Kwon sentenced to 15 years last year, why has the crackdown on market makers only intensified now?
This reflects a new characteristic of the crypto industry’s deep-water phase: Cross-Cycle Accountability. Previously, rapid crypto cycles led many wrongdoers to believe that as long as they survived the bear market, old sins would be covered by the next bull run. But the ongoing pursuit by Terra’s bankruptcy team, combining traditional bankruptcy procedures (subpoenas, communication record retrieval) with blockchain transparency (on-chain tracking), is shattering this complacency.
Jane Street’s involvement in Terra’s old case is not just a legal battle over billions in damages but a landmark moment in crypto financial history. It exposes Wall Street’s quant giants’ once-elegant and mysterious veneer in the decentralized world, revealing how, in the absence of regulation, they turn computational power and capital advantage into ruthless tools of predation.
This crackdown on the core of crypto is not overregulation but an inevitable painful step toward maturity. It sends a brutal message to all market participants: While blockchain may have no borders, every timestamp on the chain is an indelible piece of evidence in court.
For market makers, the era of blind, reckless trading is over. In future market battles, compliance will no longer be optional but a vital bottom line for survival.
