Who is "dumping" Bitcoin? A comprehensive overview of the Jane Street incident and its profound impact on the crypto market

In February 2026, the world’s top quantitative trading firm Jane Street is at the center of a rare regulatory and public opinion storm. Known for its low profile and high profits, this market maker has been thrust into the spotlight of crypto market discourse due to two separate legal incidents: one is a insider trading lawsuit filed by Terraform Labs’ bankruptcy estate, accusing it of withdrawing funds using non-public information before the 2022 Terra ecosystem collapse; the other is a temporary ban issued by India’s Securities and Exchange Board (SEBI), alleging market manipulation on derivatives expiry dates for profit.

Meanwhile, the long-standing “10 a.m. sell-off” theory in the crypto community has reignited. Many opinion leaders and retail traders blame Bitcoin’s persistent weakness during U.S. stock market open hours on systematic algorithmic manipulation by Jane Street. These events, combined with a sharp crypto market correction in early 2026, have sparked a core debate: Is the market decline caused by the “malfeasance” of individual institutions, or is it an inevitable reflection of systemic fragility?

Accusations and Timeline: From Terra Collapse to Indian Ban

Accusations against Jane Street are not isolated but span different markets and timeframes, revealing a pattern of behavior continuity.

Terraform Insider Trading Lawsuit (February 2026): Filed by Terraform’s bankruptcy estate, it alleges that Jane Street, just before the 2022 UST de-pegging, used secret chat information from Terraform insiders to withdraw 85 million UST from Curve pools. The complaint suggests this trade worsened liquidity instability, allowing Jane Street to avoid losses before the crash. Jane Street responded that the lawsuit was a “reckless money grab,” asserting that the real losses stemmed from Do Kwon’s fraud.

SEBI Temporary Ban (July 2025): India’s market regulator accused Jane Street of exploiting a “two-phase strategy” — “rising in the morning, selling in the afternoon” — to manipulate the Bank Nifty index futures around expiry, illegally profiting up to $4.3 billion. Despite warnings from exchanges, the firm continued these practices, which SEBI deemed “blatant rule violations.”

“10 a.m. Sell-off” Theory (late 2025 to early 2026): In crypto circles, opinion leaders like Whale Factor and Justin Bechler accuse Jane Street of leveraging its role as a licensed participant in the BlackRock IBIT ETF to systematically sell Bitcoin at the U.S. stock market open (Eastern Time 10 a.m.), depressing spot prices to buy ETF shares at a discount. Data shows that by Q4 2025, Jane Street held about $790 million worth of IBIT shares.

Data and Structural Analysis: Validating and Challenging Market Manipulation Claims

Faced with these serious allegations, it’s essential to distinguish “facts” from “opinions” and incorporate data and market structure analysis.

First, regarding the “10 a.m. sell-off” claim, macro analyst Alex Krüger rebutted strongly through on-chain data. Since January 1, 2026, Bitcoin’s cumulative return between 10:00 and 10:30 a.m. has been +0.9%, showing no signs of “systematic selling pressure.” Krüger pointed out that the so-called “10 a.m. dump” more likely reflects broader macro risk re-pricing, synchronized with Nasdaq and other risk assets.

Second, from a market microstructure perspective, ETF operation mechanisms offer an alternative explanation. Bitwise advisor Jeff Park notes that authorized participants (APs) do not need to buy or sell Bitcoin in strict time alignment when creating or redeeming ETF shares. This “regulatory-permitted gray window” allows for share creation, hedging, and spot trading to occur asynchronously. Therefore, even large inflows into ETFs may not immediately push spot prices higher. Ryan McMillin of Merkle Tree Capital adds that APs tend to hedge using futures (often at a premium), which causes ETF capital growth to not translate directly into equivalent spot buying, and can even exacerbate declines when futures positions are unwound.

Public Opinion Breakdown: Scapegoats and Cognitive Dissonance

Current sentiment shows clear stratification. Retail traders and some opinion leaders tend to oversimplify complex issues, seeking a specific “villain” responsible for asset declines, with Jane Street as an ideal target due to its secrecy and high-frequency trading background. This sentiment peaked after the Terraform lawsuit was made public, with some claiming “after the lawsuit, the 10 a.m. crash mysteriously disappeared.”

Institutional analysts and macro researchers present a different narrative. CryptoQuant’s Julio Moreno warns that blaming a single institution for market volatility is overly simplistic; hedging strategies are normal. Nick Puckrin of Coin Bureau suggests that Bitcoin’s weakness is better explained by geopolitical uncertainty, tightening global liquidity, and competition for funds from AI sectors. These differing views fundamentally reflect divergent beliefs about “market efficiency”: whether the market is manipulated by a few “whales,” or is a complex outcome of numerous macro and micro factors.

Scrutinizing Narrative Authenticity: Systemic Risk vs. Individual Behavior

Synthesizing multiple sources, we can differentiate the narrative’s factual basis:

• Facts: Jane Street faces Terraform’s lawsuit and SEBI’s ban; it holds substantial IBIT shares; crypto prices have fallen at certain times.
• Mainstream claims (to be verified): Jane Street used insider info to front-run Terra (pending court ruling); it manipulated Indian derivatives markets (SEBI allegations, appeal ongoing); it “dumped” Bitcoin (community theory).
• Logical speculation: Even if SEBI’s allegations are true, equating high-frequency traders’ derivative expiry manipulations with long-term trend manipulation in a 24/7 global asset like Bitcoin involves a logical leap. The scale, regulatory arbitrage, and operational complexity differ vastly.

The deeper truth may be that Jane Street’s actions (whether compliant or not) expose the crypto market’s systemic fragility. This fragility manifests in:

1. Microstructure dependence: Market depth relies heavily on a few market makers; when these giants face regulatory or risk management issues, liquidity can evaporate instantly.
2. Macro factors dominate: Macro forces like yen carry unwinding, U.S. TGA withdrawals, and derivatives deleveraging drive the overall decline. Even if Jane Street engaged in manipulation, it’s more like a participant caught in a receding tide than the cause of a tsunami.
3. Narrative inertia: The market’s habit of seeking “KOL opinions” rather than analyzing on-chain data fosters conspiracy theories.

Industry Impact: Regulatory Tightening and Market Maker Model Rebuilding

Regardless of the lawsuit’s outcome, this incident has already impacted the crypto industry substantively.

Increased regulatory expectations: SEBI’s tough stance and detailed insider trading allegations signal that as crypto assets integrate with traditional finance (e.g., ETFs), regulators will scrutinize market participants more stringently. The “gray areas” of market making and trading will be squeezed.

Market maker strategy adjustments: High-frequency traders under regulatory and public pressure may reassess their crypto risk exposure. Some may reduce market-making activities, lowering risk appetite, which could widen bid-ask spreads and increase volatility. If leading market makers pull back, liquidity could thin, amplifying price swings.

ETF operational mechanisms become a focus: Details of authorized participants’ creation/redemption timing and their impact on spot prices will attract regulatory and research attention. Calls for increased transparency in underlying ETF operations are likely to grow.

Scenario Evolution and Projections

Based on current facts, the Jane Street incident could evolve along several paths:

• Scenario 1: Legal clarification restores macro focus
  • Path: Courts dismiss some Terraform claims or Jane Street reaches settlement (e.g., in India). Market attention shifts back to inflation, Fed policies, and global liquidity.
  • Impact: Narrative of manipulation diminishes; Bitcoin’s correlation with Nasdaq normalizes. Investors focus more on macro data and on-chain metrics.
• Scenario 2: Regulatory escalation causes systemic shocks
  • Path: U.S. or other jurisdictions launch comprehensive investigations into market makers and ETF participants, prompted by this case. New rules increase compliance costs.
  • Impact: Industry consolidation, with smaller firms exiting; market concentration rises, possibly reducing liquidity. Short-term negative, long-term infrastructure improvements.
• Scenario 3: Narrative becomes entrenched, trust erodes
  • Path: Regardless of legal outcomes, the “market manipulation” story becomes deeply rooted among retail investors.
  • Impact: Tolerance for declines drops; any macro-driven correction is seen as manipulation, triggering panic selling. Trust costs rise, prolonging recovery.

Investor Strategies

In this complex environment, investors should move beyond “blame game” thinking and develop resilient strategies:

• Detach emotion, focus on data: Avoid being swayed by social media conspiracy theories. Use on-chain analytics—transaction flows, active addresses, exchange net flows—to gauge real activity, not unverified claims.
• Understand macro, manage exposure: Recognize that macro liquidity and policy are primary drivers. Control leverage, reduce exposure to high-beta altcoins, and increase allocations to stablecoins or real-world assets with strong cash flows.
• Use volatility as an opportunity: Quant strategies (active or passive) often create price dislocations. For disciplined traders, these can be opportunities for long-term positions—distinguish noise from trend reversals.
• Respect regulations, prioritize compliance: Regulatory risks are real and increasing. Choose platforms and assets with transparent, compliant operations to safeguard investments.

Conclusion

The Jane Street incident acts as a multifaceted mirror reflecting the pains of crypto’s path toward mainstream acceptance: lagging regulation, emotional and irrational public sentiment, microstructure fragility, and macroeconomic forces. Simplistically blaming a single institution for market declines offers psychological comfort but hampers understanding.

For mature investors, the real risk lies not in whether “manipulators” exist but in overexposure to a system inherently fragile and disordered. Until the truth emerges clearly, maintaining data-driven analysis, macro awareness, and disciplined strategies may be the best approach to navigate this ongoing turbulence.
