Crypto markets are once again debating the role of large institutional trading firms in major volatility events. Following the October 10 liquidation cascade, one of the largest in recent crypto history, attention has turned toward Jane Street.

The quantitative trading giant has recently faced regulatory scrutiny in multiple jurisdictions, and its deep involvement in ETF market making has placed it at the center of market structure conversations. But is there evidence linking the firm to the crash, or is this another case of markets searching for a villain after extreme volatility?

The Firm at the Center

Jane Street is one of the largest quantitative trading firms in the world. The company operates across equities, fixed income, derivatives, and increasingly, digital assets. Known for its dominance in ETF liquidity provision and arbitrage strategies, the firm has grown into one of Wall Street’s most powerful trading entities.

In recent years, Jane Street has reportedly generated around 10 billion dollars in trading revenue in a single quarter. It has also faced regulatory action in India related to alleged index manipulation. More recently, the firm has been mentioned in legal discussions tied to the fallout of the Terra ecosystem collapse.

At the same time, Jane Street has played an active role in market making for BlackRock’s iShares Bitcoin Trust, one of the largest spot Bitcoin ETFs. Its footprint in global liquidity is undeniable.

On October 10, 2025, crypto derivatives markets experienced approximately 19 billion dollars in liquidations within twenty four hours. The speed of the selloff stunned traders.

Bitcoin dropped sharply, major altcoins followed, and leveraged positions were wiped out across exchanges. Open interest collapsed as forced liquidations cascaded through perpetual futures markets.

Funding rates swung aggressively, reflecting panic positioning and sudden deleveraging. Within days, however, the market rebounded. Bitcoin reversed multiple red weekly candles and total crypto market capitalization expanded significantly.

The Terra collapse in May 2022 remains one of the most devastating episodes in crypto history. When Terra’s algorithmic stablecoin lost its peg, roughly 40 billion dollars in value evaporated within days.

The collapse triggered forced liquidations, fund insolvencies, and months of broader market stress. During periods like that, large trading firms, including quantitative market makers, are highly active as they manage risk and arbitrage price discrepancies.

However, volatility during structural failures does not automatically imply orchestration. Crypto has experienced similar liquidation cascades in 2020, 2021, and multiple times since. Excessive leverage combined with thin liquidity has repeatedly proven sufficient to trigger dramatic collapses without coordinated action.

ETF Market Making and Institutional Flows

Institutional participation in crypto has expanded significantly with the approval of spot Bitcoin ETFs. Firms like Jane Street act as liquidity providers in these products, facilitating share creation and redemption while hedging exposure in underlying markets.

ETF market makers typically operate neutral strategies. They profit from spreads and arbitrage rather than directional bets. However, during extreme volatility, liquidity providers may widen spreads or reduce exposure to manage risk.

When liquidity thins during high leverage conditions, price impact increases. This can amplify liquidation cascades even if no coordinated manipulation is taking place. Institutional scale changes market structure. It does not necessarily imply malicious intent.

🚨IS JANE STREET ALSO BEHIND THE OCTOBER 10TH CRASH, THE LARGEST LIQUIDATION EVENT IN CRYPTO HISTORY?

Look at the pattern.

How Liquidation Cascades Actually Work

Crypto markets are uniquely reflexive due to leverage. When traders use high leverage in perpetual futures, even small price moves can trigger forced liquidations.

Once liquidation engines begin executing market orders, those sales push prices further down. The drop triggers additional liquidations, creating a feedback loop. Within minutes, billions can evaporate.

In modern crypto markets, retail participants are no longer the only major actors. Large quantitative firms, hedge funds, ETF issuers, and institutional desks now provide substantial liquidity.

When massive liquidation events occur, attention naturally turns toward firms with the scale to move billions. Jane Street fits that profile due to its global footprint and active role in ETF markets.

Liquidity providers can unintentionally intensify volatility simply by reducing exposure during periods of stress. Risk management decisions made simultaneously across firms can create sharp price gaps.

However, there is currently no verified public evidence directly linking the firm to orchestrating the crash. Crypto markets remain structurally vulnerable to leverage driven cascades.
