DOJ charges two ex-Robinhood engineers over Hyperliquid perp trades ahead of listings
Prosecutors say Hefu Chai and Huaisong Xiang each cleared more than $50,000 from long perpetual positions on Hyperliquid, opened on planned listing dates they read in a private Robinhood Slack channel.

What happened
- US prosecutors on Tuesday charged former Robinhood engineers Hefu Chai and Huaisong Xiang with commodities fraud and wire fraud over perpetual futures trades placed ahead of the firm's crypto listings.
- The Department of Justice alleges each man profited more than $50,000 from the trades between 2025 and 2026.
- Chai is alleged to have traded perpetuals ahead of at least 10 announcements, involving tokens including MEW, MOODENG, ASTER, XPL, HYPE, ENA and AERO.

Why it matters
- exposure A mid-five-figure gain now sits opposite a 30-year statutory ceiling per defendant if prosecutors prevail on both counts.
- constraint Compliance work at a listing venue moves from writing the blackout to detecting positions on books the firm does not operate. That is a data-purchase problem.
- precedent With tokenized securities named alongside perpetual futures by the US Attorney, the next charging document on this theory need not involve a perp at all.
- decision Every exchange that maintains a pre-listing information group now has to choose between shrinking it and paying to watch what its members do off-platform.
On the minimum count of ten announcements, more than $50,000 of alleged profit averages about $5,000 a trade [1], and the two counts against each defendant carry maximum terms of 10 and 20 years, a combined ceiling of 30 [9][2]. Between the two men the alleged gain is more than $100,000 [3]. Prosecutors put the trading ahead of at least 21 listing announcements in total [5].
The instrument is the new part. Prosecutors allege the two opened long perpetual contracts linked to tokens before the Robinhood Crypto listings and closed them once the price rose after the debut [2][4]. In the 2023 Coinbase insider-trading case, according to Cointelegraph, the former employee bought the underlying assets directly, and this case extends the issue into decentralized derivative markets [13].
Robinhood had written the rule already: both engineers were designated Coin Aware Individuals, which gave them a private Slack channel carrying planned listing dates [5]. Company policy barred that group from trading on Robinhood or any other platform for 24 hours before or after a listing or delisting announcement [6], a 48-hour blackout per event [4]. So the policy reached other venues on paper. Making it bite means seeing positions on someone else's book, and Cointelegraph's account of the complaints is silent on how the trades were traced to the two engineers [15].
US Attorney Jamie McDonald said corporate insiders cannot evade securities and commodities laws by trading misappropriated information through perpetual futures, tokenized securities or similar instruments [10]. Chai was a technical lead responsible for new digital-asset listings from around 2021 until May 2026; Xiang was a software engineer involved in crypto listings from around 2024 until September 2026 [14].
The venue is incidental on one reading. The theory is misappropriation of an employer's information, the statutes charged are pre-existing, and a Commodity Exchange Act count reaches a derivative the way a fraud count reaches a spot purchase [1][9]. On the other, reconstructing flow on a decentralized perp market is the expensive part, slower and dearer than pulling a broker's own blotter. I lean to the second. If the charging documents show Robinhood's internal surveillance flagged the accounts, that lean is wrong and the perp adds nothing but a name.
The allocation question for a listing desk follows from the same point. Buying visibility into employee activity on venues it has no relationship with is expensive; cutting the number of names that see planned dates is cheap, and it is the control most likely to move first.
Robinhood did not respond to Cointelegraph's request for comment [11]. The charges remain allegations, and both defendants are presumed innocent unless convicted [12].
What to watch
- Whether Robinhood narrows the Coin Aware Individuals designation or says anything publicly after not responding to Cointelegraph.
- Whether the tokenized securities that US Attorney Jamie McDonald named alongside perpetual futures appear in a later charging document.
- Whether the charging documents or a later filing show how the Hyperliquid positions were identified, internally or by prosecutors.
