Robinhood Engineers Charged Over Hyperliquid Perpetuals Trades

Two former Robinhood engineers face federal charges of commodities fraud and wire fraud after the U.S. Attorney’s Office for the Southern District of New York alleged they used material nonpublic information about upcoming coin listings to trade perpetual futures on Hyperliquid, pocketing more than $50,000 each in alleged illicit profits.

What the charges allege

The FBI complaint against Hefu Chai alleges he accessed confidential Robinhood listing information and placed Hyperliquid perpetual futures trades ahead of at least 10 public listing announcements, spanning 2025 through January 2026. The complaint alleges more than $50,000 in illicit profits from those trades. For related coverage, see Binance Launches Wealth Management Service With 11 US-Listed ETFs.

A separate complaint against Huaisong Xiang, also known as Jerry Xiang, mirrors the same charge structure. The Xiang complaint describes one initial trade sequence plus at least 10 additional pre-announcement perpetual trades between May 2025 and February 2026, with alleged illicit profits also exceeding $50,000, as CoinDesk confirmed in a corroborating report.

The complaints invoke Robinhood’s internal “Coin Aware Individuals” designation, a classification that restricted employees with knowledge of pending listings from trading the relevant assets for at least 24 hours after any public announcement. Both Chai and Xiang allegedly bypassed that restriction by trading perpetuals on an external decentralized derivatives venue rather than spot markets within Robinhood’s own platform. The complaints characterize this as commodities fraud under 7 U.S.C. §§ 9(1) and 13(a)(5) and wire fraud under 18 U.S.C. § 1343. These are allegations, not convictions.

One trade spelled out in the complaint

The Chai complaint identifies a specific example: Chai allegedly opened and closed a HYPE perpetual position on Hyperliquid on October 23, 2025, before Robinhood publicly announced it would list HYPE. That single instance illustrates the alleged scheme’s structure: take a directional position in the perpetuals market before an announcement that would predictably move spot price, then close after the listing is public.

Why Hyperliquid perpetuals are central to the case

Perpetual futures are derivative contracts that provide leveraged price exposure to an underlying asset without an expiry date. Unlike spot purchases, they do not require the trader to custody the underlying token, and on a decentralized venue like Hyperliquid they leave a different compliance footprint than a brokerage account connected to a known identity. That structural feature appears relevant to why the alleged scheme used this instrument and venue rather than direct spot trading.

Hyperliquid has grown into one of the largest on-chain derivatives protocols by volume. At data collection, its native token HYPE was trading at $77.81, down 1.82% over the prior 24 hours, against a market capitalization of roughly $17.3 billion and 24-hour volume near $895 million.

The case arrives as Robinhood’s on-chain footprint has been expanding rapidly. The company’s blockchain infrastructure has faced growing pains, including congestion events that pushed Robinhood Chain out of Ethereum blob space during traffic spikes, while the Arbitrum DAO has been reporting revenue streams tied to Robinhood Chain activity. The insider-trading allegations add a compliance dimension to that broader infrastructure buildout.

What to watch next

Both complaints are charging documents filed by the FBI, not indictments returned by a grand jury. The next procedural steps are initial appearances in federal court, potential bail hearings, and decisions by the SDNY on whether to seek formal indictments. Statements from Robinhood or Hyperliquid, if issued, would clarify whether either company is cooperating with investigators or has taken internal disciplinary action.

Allegations versus findings

Nothing in the complaints establishes guilt. Under U.S. law, defendants are presumed innocent until proven guilty in court. The specific allegations, including the profit figures, trade counts, and the “Coin Aware Individuals” policy mechanics, are the government’s theory of the case and will be tested against evidence presented at trial or in any plea proceedings.

The broader regulatory question surfaced by these filings is whether decentralized perpetuals venues create a compliance gap that traditional employee-trading policies do not address. That question will likely appear explicitly in court filings as the cases develop, with potential implications for how other DeFi derivatives protocols handle insider-information risk frameworks going forward.
