  • Robinhood Engineers Charged After Allegedly Trading Crypto on Secret Listing Information

    Robinhood Engineers Charged After Allegedly Trading Crypto on Secret Listing Information

    Key Highlights

    • Two Robinhood engineers, Hefu Chai and Huaisong Xiang, have been charged by the U.S. Department of Justice with commodities fraud and wire fraud for allegedly using confidential listing information to trade crypto perpetual futures on Hyperliquid.
    • Prosecutors allege the defendants generated over $50,000 each by repeatedly trading tokens ahead of public Robinhood Crypto listing announcements between 2025 and 2026.
    • The case draws parallels to the Jane Street Group controversy, where the trading firm allegedly exited $192 million in TerraUSD (UST) prior to its May 2022 collapse using alleged insider access.

    Robinhood Engineers Charged in Alleged Insider Trading Scheme

    The U.S. Department of Justice has unsealed criminal complaints against two Robinhood Markets engineers, accusing them of orchestrating a systematic scheme to exploit confidential corporate data for personal profit in the cryptocurrency derivatives market. Hefu Chai, 36, of Menlo Park, California, and Huaisong Xiang, 30, of Jersey City, New Jersey, face charges of commodities fraud and wire fraud stemming from their alleged misuse of non-public information regarding upcoming token listings on the Robinhood Crypto platform.

    Trading on Confidential Listing Data

    According to complaints filed in the Southern District of New York, Chai and Xiang leveraged their positions as engineers to access advance knowledge of which cryptocurrencies Robinhood planned to list for trading. Prosecutors contend that the defendants used this privileged information to purchase perpetual futures contracts tied to those specific tokens on Hyperliquid, a decentralized perpetual futures exchange, before the listings were announced to the general public. The DOJ alleges this pattern of trading was repeated multiple times over a period spanning 2025 and 2026, with each defendant allegedly realizing profits exceeding $50,000.

    Severe Penalties and Upcoming Court Appearances

    The charges carry significant potential prison time. The commodities fraud count carries a maximum sentence of 10 years, while the wire fraud charge carries a maximum of 20 years. Chai is scheduled to make his initial appearance in federal court in the Northern District of California, while Xiang is set to appear before a federal magistrate judge in New York. The geographic split reflects the defendants’ respective residences and the national scope of the alleged electronic communications used to execute the trades.

    DOJ Signals Crackdown on Derivatives-Based Insider Trading

    U.S. Attorney Jamie McDonald emphasized the broader legal implications of the case in a formal statement:

    “Misappropriating confidential information to trade in the derivatives markets for personal benefit is illegal. That is exactly what we allege Hefu Chai and Huaisong Xiang have done. Today’s charges make clear that corporate insiders cannot evade the securities and commodities laws by trading based on misappropriated information in derivatives like perpetual futures, tokenized securities, or other similar financial instruments.”

    The statement underscores the Justice Department’s intent to apply traditional insider trading statutes to novel crypto-native instruments, specifically perpetual futures, signaling that the regulatory perimeter extends beyond spot markets into decentralized derivatives venues.

    Why This Matters: Regulatory Scrutiny Extends to Crypto Derivatives

    This prosecution arrives amid heightened regulatory focus on market integrity within the digital asset ecosystem. The allegations against Chai and Xiang represent a notable expansion of enforcement theory: applying misappropriation theory to perpetual futures traded on decentralized platforms like Hyperliquid, rather than traditional securities or spot crypto assets. It establishes a precedent that confidential corporate information—such as exchange listing schedules—is protected property regardless of the financial instrument used to monetize it.

    The case also resurfaces scrutiny on institutional players. The Jane Street Group controversy, referenced in the DOJ’s background context, involved allegations that the quantitative trading firm utilized a private Telegram channel with Terraform Labs insiders to sell approximately $192 million in TerraUSD (UST) ahead of the algorithmic stablecoin’s catastrophic de-pegging in May 2022. While distinct in mechanism—one involving exchange listing data, the other protocol-level stability intelligence—both cases illustrate a regulatory environment where information asymmetry, whether at a broker-dealer or a protocol issuer, is increasingly actionable.

    For Robinhood, the charges pose reputational risk as the firm continues its push to deepen its crypto product suite. For the broader industry, the message is clear: the Commodity Futures Trading Commission (CFTC) and DOJ view perpetual futures and similar derivatives as fully within their jurisdictional reach for fraud and manipulation enforcement.

    Frequently Asked Questions

    What specific charges do Hefu Chai and Huaisong Xiang face?

    Both defendants are charged with one count of commodities fraud, carrying a maximum 10-year sentence, and one count of wire fraud, carrying a maximum 20-year sentence, in the Southern District of New York.

    How did the alleged scheme work according to prosecutors?

    Prosecutors allege Chai and Xiang used their engineering roles at Robinhood to access non-public information about upcoming cryptocurrency listings on Robinhood Crypto. They then allegedly purchased perpetual futures contracts for those tokens on Hyperliquid before the listings were publicly announced, profiting from the price movements that typically follow a major exchange listing.

    What is the significance of the Jane Street comparison mentioned in the report?

    The Jane Street case, involving a $192 million exit from TerraUSD prior to its 2022 collapse, is cited as a parallel high-profile instance where sophisticated market participants allegedly used non-public information—via a private channel with Terraform Labs—to trade advantageously. Both cases highlight expanding enforcement against information asymmetry in crypto markets, whether on centralized platforms or decentralized protocols.

  • Susquehanna Loses Bid to Freeze $100M in Alleged Insider Trading Case

    Susquehanna Loses Bid to Freeze $100M in Alleged Insider Trading Case

    New York Federal Judge Denies Susquehanna’s Bid to Freeze $100 Million in Alleged Insider Trading Case

    A U.S. District Court judge in Manhattan has rejected an attempt by Susquehanna Securities and Susquehanna Investment Group to freeze nearly $100 million linked to dozens of traders accused of profiting from nonpublic information ahead of a Chinese regulatory crackdown on cross-border trading platforms.

    Lawsuit Background and Allegations

    Susquehanna filed the lawsuit on June 29 against 100 unnamed defendants, alleging violations of Section 20A of the Securities Exchange Act of 1934 and unjust enrichment. Citadel Securities later joined the case as an intervenor. The dispute centers on trading activity preceding a May 22 announcement by the Chinese government targeting cross-border brokerage services offered to mainland investors without regulatory approval.

    The market maker alleged that the defendants traded using material nonpublic information before the news triggered a sharp decline in certain securities. Susquehanna initially targeted 100 defendants but narrowed its request for a preliminary injunction to 40, seeking to prevent them from transferring, encumbering, or disposing of proceeds held at third-party brokerage firms. As an alternative, the company requested an attachment order to seize assets to secure a potential judgment.

    Court Finds No Irreparable Harm to Justify Asset Freeze

    In a September 14 opinion and order, Judge Arun Subramanian ruled that Susquehanna had not demonstrated a likelihood of irreparable harm without a preliminary injunction. The judge found insufficient evidence that the defendants were likely to dissipate or conceal assets before a judgment could be enforced.

    Susquehanna argued that the defendants’ allegedly suspicious trading created a significant risk that proceeds could be moved beyond the court’s reach. Subramanian rejected this reasoning, stating that accepting it would effectively allow asset freezes as a matter of course in many insider trading or fraud cases.

    The court analyzed three groups separately: domestic defendants, foreign defendants who had appeared in the case, and foreign defendants who had not appeared. For domestic defendants, the judge found no evidence that their failure to appear indicated an intent to frustrate enforcement, noting some may not have been formally served. Regarding foreign defendants, the court held that the potential difficulty of enforcing a judgment overseas does not, by itself, establish irreparable harm.

    Susquehanna did not identify a pattern of defendants hiding funds, making fraudulent transfers, or engaging in evasive conduct. Some foreign defendants who appeared submitted evidence showing they had sufficient funds to satisfy a potential judgment.

    The company came closest to establishing risk regarding one defendant, identified as John Doe 3, who allegedly removed more than $10 million from a relevant account before a freeze took effect. The court found the claim lacked supporting evidence and noted that moving money from an account does not necessarily indicate an attempt to avoid a judgment; funds used for active trading could have been reinvested elsewhere or belonged to a fund, employer, or client.

    Trading Patterns Do Not Establish Likely Insider Trading

    Beyond irreparable harm, Susquehanna failed to demonstrate a likelihood of success on the merits of its Section 20A claim. To prevail, the company would need to prove that someone owing a fiduciary duty used material nonpublic information to trade or tipped that information to others.

    Susquehanna submitted trading charts showing defendants buying highly risky, short-dated put options expiring on or shortly after the May 22 announcement, arguing no plausible explanation existed other than insider trading. However, defendant Zhengfei Li offered an alternative explanation. His records showed two equally sized positions, half expiring before May 22 and half afterward. Li told the court the pattern was consistent with repeated speculation based on public market signals, citing unusually heavy put option activity visible through public market information and investor discussions.

    Evidence submitted by Li showed a put-to-call ratio of roughly 49 to 1 on May 21, the day he entered positions expiring after the announcement. Another defendant provided similar reasoning and submitted messages showing her reaction when the crackdown became public.

    The court concluded that defendants could have noticed unusual market volatility or publicly available posts suggesting negative news was approaching and traded on those signals. Information available publicly does not qualify as nonpublic information under insider trading law. While some defendants’ trading records appeared more suspicious than Li’s, Susquehanna relied on broad arguments across a large group rather than providing detailed individual analysis. The judge noted the scale of the original case—accusing 100 defendants of receiving insider information—even though Susquehanna later stopped seeking an injunction against more than half of them.

    Susquehanna had not identified the alleged tipper, the fiduciary duty owed, or the personal benefit received for providing the information. The court found the large number of unconnected investors could support explanations other than insider trading.

    Context: China’s Crackdown on Cross-Border Trading

    The May 22 regulatory action at the center of the case involved Chinese scrutiny of overseas trading services offered to mainland investors. Previous reporting indicated Chinese securities regulators targeted cross-border brokerage activity involving firms such as Tiger Brokers, Futu, and Longbridge. The action concerned companies providing mainland clients access to overseas markets without regulatory approval.

    China had already tightened restrictions on crypto and real-world asset tokenization in February, extending restrictions to offshore entities serving mainland users and maintaining limits on virtual currency-related financial services. Days after the May 22 development, China’s Supreme People’s Court said judicial authorities would study rules for virtual currency disputes and cases involving cross-border financial activity.

    Enforcement involving overseas fund movements continued in July, when a Shanghai court sentenced five people over an illegal foreign exchange network that prosecutors said used cryptocurrency to move more than $29.4 million abroad. Authorities said the network helped domestic clients transfer more than 200 million yuan overseas over three years.

    Alternative Attachment Request Also Denied

    Susquehanna’s failure to establish likely success on the merits also doomed its alternative request for an attachment order under Federal Rule of Civil Procedure 64. In New York, a party seeking attachment must show, among other requirements, that it is probable to succeed on the merits.

    Susquehanna relied on the same arguments presented for the preliminary injunction. Subramanian found the company had not demonstrated likely success on either its Section 20A claim or its unjust enrichment claim. The unjust enrichment allegation was based on the same underlying claim of illegal insider trading, and the court found Susquehanna had not clearly shown defendants traded using material information unavailable to the market.

    Questions also remained over the extent of Susquehanna’s losses because the market maker acknowledged using hedging strategies. The record did not establish how much of the defendants’ alleged gains, if any, came at the plaintiffs’ expense.

    Subramarian stressed that the ruling did not decide whether Susquehanna had adequately pleaded plausible claims for relief, an issue the court had not yet addressed. The higher standard required to freeze funds totaling just under $100 million had not been met. The court denied both the preliminary injunction and the alternative attachment request. An earlier order restricting the funds was set to dissolve at 5 p.m. ET on September 16.

  • CFTC Probes Polymarket Trades Linked to Biden Pardons, Iran, Google, Report Says

    CFTC Probes Polymarket Trades Linked to Biden Pardons, Iran, Google, Report Says

    CFTC Opens Three Insider Trading Investigations Into Polymarket

    The Commodity Futures Trading Commission has launched at least three previously unreported investigations into suspected insider trading on the prediction market platform Polymarket, according to a report from WIRED. The probes target event contracts tied to presidential pardons issued by former President Joe Biden, Iran-related geopolitical outcomes, and Google’s 2025 Year in Search rankings.

    First Probe Follows NPR Report on Pardon Markets

    CFTC Chairman Michael Selig approved the first investigation in early May. The action followed an NPR report detailing a trader who earned more than $300,000 from pardon-related markets after correctly predicting several preemptive pardons.

    Second Investigation Targets Iran Contracts

    A second investigation was approved at the end of May. This probe centers on Iran-related contracts and was prompted by a 60 Minutes report on accounts that reportedly earned $2.4 million with a 98% win rate.

    Third Probe Examines Google Search Rankings

    In July, the CFTC approved a third investigation into suspected insider trading involving Google’s 2025 Year in Search ranking. An agency official said the probe would examine additional individuals and noted that the Southern District of New York was conducting a parallel investigation.

    CFTC enforcement officials clarified that this investigation is separate from an existing case against former Google engineer Michele Spagnuolo, who allegedly made more than $1.2 million trading Polymarket contracts based on confidential information about Google’s 2025 Year in Search rankings.

    Polymarket’s U.S. Return Under CFTC Oversight

    Polymarket has been working to rebuild its reputation in the United States after four years of operating outside the country. In late 2025, the company relaunched in the U.S. following the acquisition of QCEX, granting Americans limited access to its event contracts under CFTC oversight.

    Previous DOJ and CFTC Probe Concluded

    The Justice Department, alongside the CFTC, previously examined whether the crypto prediction market circumvented restrictions on U.S. traders imposed under a 2022 settlement with the CFTC. The authorities ended that probe in July 2024.

  • Kalshi Bans George Santos Over $17,839 Market Manipulation

    Kalshi Bans George Santos Over $17,839 Market Manipulation

    Kalshi has permanently banned former U.S. Representative George Santos and imposed a $71,356 penalty after determining that he manipulated an event market tied to his attendance at President Donald Trump’s 2026 State of the Union address. The exchange said Santos earned $17,839.57 from the trades.

    Kalshi says Santos traded on an outcome he could control

    In an Aug. 28 disciplinary notice, Kalshi said Santos placed large trades between Feb. 2 and Feb. 25 in contracts that paid out depending on whether he attended the address.

    Because Santos’s attendance determined the contracts’ result, he could directly influence the underlying event. Kalshi Rule 5.17(z) prohibits members from trading contracts when they can affect the outcome.

    Despite the restriction, Kalshi’s compliance department found that Santos bought and sold contracts tied solely to his own attendance. His positions included both “Yes” contracts, which paid if he appeared at the event, and “No” contracts, which paid if he did not.

    During the trading period, Santos published several statements about his travel and attendance plans. Kalshi said some of the posts were false or misleading and were intended to move prices before he bought or sold the related contracts.

    The exchange determined that the statements affected the market as intended. By shifting between “Yes” and “No” positions while controlling information about his plans, Santos generated $17,839.57 in profit, according to the notice.

    Kalshi cited violations involving market manipulation, trading with material nonpublic information, trading on an outcome a member can influence, and using a deceptive scheme connected to exchange activity. The exchange’s compliance department also found that Santos did not cooperate promptly and fully with its internal investigation.

    Under the settlement, Santos cannot access Kalshi directly or through another person or account. The exchange also imposed a $71,356 penalty, exactly four times the profit amount listed in its notice. The disciplinary document took effect on Aug. 28.

    Social media posts moved Santos attendance contracts

    A separate Commodity Futures Trading Commission order issued on July 31 provided a more detailed timeline of Santos’s trades. According to the regulator, Santos opened his Kalshi account on Feb. 11 and deposited about $7,000, using the funds exclusively to trade on his own attendance.

    From Feb. 12 through Feb. 22, Santos accumulated 30,874 “Yes” contracts at a total cost of $6,695.94. While holding the position, he asked his X followers whether he should wear a serious suit or a bedazzled one to the address.

    After the post, the “Yes” contract rose from about $0.15 to $0.70. Santos then sold the entire position for a $3,448.43 profit and withdrew $10,146.07 through a Venmo account created four days earlier, the CFTC said.

    Later on Feb. 22, an airline notified Santos that his flight to Washington, D.C., had been canceled. He booked a train that night, then posted the following morning that bad weather had made his trip difficult and suggested that the address might not take place. The “Yes” price fell from $0.63 to $0.28 after the post.

    On the evening of Feb. 23, Santos posted that he would attend from the House gallery. According to the federal order, a video repeating his attendance plans pushed the contract price from $0.40 to $0.70.

    About 40 minutes after publishing the video, Santos began buying “No” contracts. He eventually acquired 23,855 contracts for $8,650.66. His train was canceled about an hour after he began building the position, but he later responded, “I am” when another user asked whether he was still going.

    With both his flight and train canceled, Santos had not bought another ticket when he posted on Feb. 24 that he was watching the address on an airport television. The “Yes” contract fell from $0.73 to $0.02, increasing the value of his opposing position.

    The CFTC found that Santos closed the “No” trade early on Feb. 25 for a $14,390.57 profit. Combined with his earlier gain, the two positions generated the amount later addressed in Kalshi’s disciplinary action.

    Federal penalties are separate from Kalshi’s lifetime ban

    Kalshi’s sanction is separate from the CFTC settlement, which imposed different payment amounts and a shorter restriction covering all federally registered trading venues.

    As crypto.news previously reported, the CFTC ordered Santos to disgorge $17,569.98, pay a $17,500 civil penalty, and stop trading on any CFTC-registered entity for three years. Santos consented to the July order without admitting or denying its findings or legal conclusions.

    The regulator applied Section 6(c)(1) of the Commodity Exchange Act and Regulation 180.1, which prohibit manipulative or deceptive conduct involving swaps. The order classified the State of the Union event contracts as swaps because their payouts depended on a future event with possible financial, economic or commercial consequences.

    Although Kalshi cited Santos for failing to cooperate with its inquiry, the CFTC recognized his cooperation in the federal investigation. The findings relate to two separate reviews conducted by the exchange and its regulator.

    Earlier in June, federal investigators were examining the trades after Kalshi froze Santos’s account and referred the activity to authorities. The CFTC later resolved its part of the matter through the July settlement, while the reported Justice Department inquiry has not received a publicly announced resolution.

    Prediction markets expand controls after insider-trading cases

    Kalshi operates as a designated contract market under CFTC oversight, making its event contracts subject to federal derivatives rules and exchange-level restrictions. Users trade contracts priced according to the perceived likelihood of outcomes involving politics, sports, economic data and other public events.

    Concerns about privileged information have increased as contracts tied to speeches, political decisions and unpublished content attract more trading. In February, Kalshi imposed a $20,397.58 penalty and a two-year suspension on a MrBeast-affiliated editor over trades involving unreleased YouTube videos.

    A separate federal case involves U.S. Army Special Forces member Gannon Ken Van Dyke, whom prosecutors accused of using classified information to earn about $409,881 from Polymarket contracts linked to the capture of Nicolás Maduro. A federal judge paused the CFTC case in August while the related criminal proceeding continues. Van Dyke has pleaded not guilty and disputes whether the contracts qualify as swaps.

    Kalshi has also introduced employer-disclosure rules, a whistleblower channel and risk reviews for proposed markets. In June, it partnered with StarCompliance so participating financial firms could connect employee accounts to internal monitoring systems.

    The exchange said it conducted more than 150 investigations during the first quarter of 2026, blocked more than 100 suspected insider-trading attempts and referred 20 cases to law enforcement.
