Ex-Robinhood Engineers Charged Over Hyperliquid Trades

DOJ says Hefu Chai and Huaisong Xiang used confidential listing info to trade crypto perpetuals on Hyperliquid, earning over $50,000 each.

Federal prosecutors charged two former Robinhood engineers with commodities fraud and wire fraud on Tuesday, alleging they traded crypto perpetual futures on confidential information about upcoming token listings. Hefu Chai, 36, and Huaisong “Jerry” Xiang, 30, worked at Robinhood Markets when the trades took place between 2025 and 2026. Each allegedly earned more than $50,000.

Manhattan U.S. Attorney Jamie McDonald announced the charges. According to the Justice Department, the two had access to a private Slack channel where Robinhood planned which cryptocurrencies its brokerage would support. Before those listings became public, they allegedly opened long positions on Hyperliquid, a decentralized derivatives exchange, and closed them once the announcements moved token prices.

How the scheme worked

Prosecutors said the trades covered several crypto asset listings and were executed through perpetual contracts rather than direct purchases of the underlying tokens. That detail separates the case from earlier listing front-running prosecutions. When Robinhood announces support for a token, the price typically jumps, so a long position opened hours in advance captures the move without ever touching the spot asset.

Perpetual futures are leveraged derivatives with no expiry date, which makes them a natural vehicle for this kind of trade. A position on Hyperliquid can be opened with a few clicks, in size far beyond what a spot purchase on a monitored exchange would allow, and closed minutes after the news lands. The government did not name the tokens involved, and the indictment has not been unsealed in full.

Chai faces up to 10 years in prison on the commodities charge and up to 20 on the wire fraud count, with the same exposure for Xiang. The Justice Department’s press release describes the conduct as trading “on the basis of confidential business information.” Robinhood did not respond to a request for comment before publication.

A familiar case on new rails

The allegations closely parallel the 2023 Coinbase insider trading case, in which a former product manager used confidential listing information to buy tokens before announcements. That case led to convictions and became the template for listing front-running prosecutions.

The Robinhood case extends the same theory into decentralized markets. Hyperliquid runs without a traditional intermediary, and perpetual futures are derivatives, not securities in most readings. Prosecutors framed the conduct as commodities fraud, which lets them reach trades on a venue that sits outside the SEC’s jurisdiction. Legal observers have expected this move since perpetuals volume on decentralized exchanges grew past most centralized venues.

It also tests whether misappropriation theory, normally applied to securities and corporate information, works against data flows inside a crypto company. The government’s answer, in this indictment, is yes: the Slack channel carried confidential business information, and trading on it is fraud regardless of where the trade executes.

For Robinhood, the reputational math is manageable. The company moved quickly to describe the defendants as former employees and has cooperated in past insider trading matters involving its own staff. The bigger question is whether brokerages listing tokens now treat listing schedules as material nonpublic information with the same rigor banks apply to earnings dates.

There is a second-order question for Hyperliquid itself. The venue has no KYC gate, and its largest traders are pseudonymous. If US authorities start treating activity on it as prosecutable, the exchange faces the choice every offshore crypto venue eventually faces: geo-block US users or absorb enforcement risk. Hyperliquid has not commented.

Context: a rough week for crypto equities

The charges landed during a sharp pullback in crypto markets. Bitcoin traded near $75,900 on Tuesday, down about 2.85% in 24 hours, and ether fell harder, around $2,400. The Crypto Fear and Greed Index dropped from 69 to 51 overnight, a fast swing from greed to neutral.

US spot Bitcoin ETFs recorded roughly $450.4 million in net outflows in the latest session, the largest single-day withdrawal since late June, according to Farside data. September has seen larger swings between inflows and outflows than August, and flow data has become the indicator institutional desks watch most closely for allocation shifts.

Derivatives markets saw about $571 million in long liquidations over 24 hours, including roughly $190 million each in bitcoin and ether longs. XRP longs lost about $30 million and SOL longs $22 million. Short liquidations totaled around $100 million, so the deleveraging ran almost entirely against bullish positions. BTC had climbed from around $77,000 to nearly $80,000 before reversing, which is when the leveraged longs built up.

The Senate’s failure to advance the CLARITY Act on Monday added pressure. Shares of Circle and a major crypto exchange fell about 10%, Strategy and Strive each dropped around 5%, and miners fared no better, with Riot Platforms down about 6% and CleanSpark near 5%. Hut 8 and IREN each lost around 4%. The CLARITY Act had been under negotiation for months, covering digital asset classification, regulatory jurisdiction, stablecoin provisions and ethics rules for officials holding crypto.

What happens next

Both defendants will face arraignment in the Southern District of New York. Prosecutors have not said whether more people are charged or whether Robinhood itself faces any exposure. The company has previously cooperated in insider trading matters involving its own staff.

For decentralized exchanges, the case is a signal. Hyperliquid has grown into one of the largest perpetuals venues in crypto, and US prosecutors have now charged conduct that took place entirely on it. Expect compliance teams at every protocol with US users to reread their terms of service this week.
