SEC Investigates Market Maker Susquehanna: Suspected Insider Trading Profits Exceed $100 Million
The U.S. SEC is investigating market maker Susquehanna for allegations of insider trading, as unknown trading parties made significant purchases of related U.S. stock options before the Chinese regulators announced a crackdown on cross-border brokers Futu Holdings and Tiger Brokers on May 22.
These trading parties reportedly profited at least $100 million with an investment of about $12 million, while Susquehanna, as the counterparty, incurred losses exceeding $70 million. U.S. courts have frozen assets in suspected related accounts at Interactive Brokers, Futu, and Up Fintech, and allowed subpoenas to disclose the actual identities of the account holders.
Market mechanisms indicate that precise options betting drove rapid capital inflow into bearish positions before the regulatory event, with information asymmetry causing market makers to passively assume risk exposure. Profiting parties benefited from prior knowledge of the crackdown, while liquidity providers like Susquehanna faced pressure and losses, prompting regulatory intervention.

Susquehanna, as a major global market maker, has faced significant losses in the past due to information advantages held by counterparties in high-frequency trading and options markets during similar cross-border events. This time, they have proactively initiated a John Doe lawsuit and sought SEC support to trace the trading parties.
In terms of capital pathways, the unknown trading parties leveraged options to mobilize limited funds for precise bets, motivated by the use of non-public regulatory information to achieve high returns. Their actions included purchasing a large number of short-term put options within two weeks and closing positions for profit after the announcement, facilitating resource transfer from information channels to offshore capital platforms.
Similar to previous abnormal trading cases before Chinese regulatory crackdowns on specific industries, this case marks a transition for market makers and regulators from passive losses to active enforcement, coinciding with the regulatory cycle of penalties against Futu and Tiger Brokers.
Essentially, this reflects a regulatory change: the breach of cross-border information barriers has temporarily shifted pricing power to informed parties. Through court freezes and SEC investigations, there is a mechanism for returning to compliant market makers, aimed at enhancing market fairness to prevent systemic capital outflow due to insider trading.

The more extreme the information asymmetry, the more astonishing the leveraged profits, and the more inevitable the regulatory accountability. Market maker losses signal market conditions, with the ultimate burden always falling on the compliance system. Abnormal trading before regulatory crackdowns reveals capital flows that disclose the truth earlier than the announcements themselves.
