Three weeks ago I wrote about Lazarus wallets moving $30 million through Hyperliquid while the CFTC review was pending. I called it the compliance story nobody wanted to talk about. Today Congress decided to talk about it.
On September 29, House Oversight Chairman James Comer expanded his prediction market insider trading investigation to three new platforms. Hyperliquid Labs is one of them. The letter went straight to co-founder Jeff Yan, and the deadline is October 13.
Here is what the probe covers, why Hyperliquid got pulled into a prediction market inquiry, and what it means for everyone farming Season 3.
What the Hyperliquid Insider Trading Probe Actually Asks
The short version: Congress wants to know who is trading on Hyperliquid, how the platform verifies them, and what it does when a trade looks suspicious.
The three letters went to Hyperliquid Labs, Crypto.com, and Aristotle Exchange, the company behind PredictIt. All three must hand over records covering customer verification procedures and suspicious trading controls by October 13. The requests reach back to January 1, 2024.
The Hyperliquid letter goes further than the other two. Lawmakers want documents on geographic restrictions, trading surveillance, regulatory compliance, and any employees who hold government security clearances. That last item tells you where this is heading.
Comer’s investigation started in May 2026. The original targets were Polymarket and Kalshi, which have already handed over nearly 1,000 documents and sat through five briefings. This is the first time a perp DEX has been added to the list.
The $1.1 Billion Short That Started It
Every congressional letter needs a villain, and this one has a big one.
The letter cites a $1.1 billion leveraged short across Bitcoin and Ether perpetuals, opened roughly 30 hours before Trump’s October 2025 tariff announcement. The trader closed shortly after the crash and walked away with more than $150 million in profit.
Anyone who was trading last October remembers that weekend. It was the largest liquidation event in crypto history. Most of us got hit. One wallet on Hyperliquid got paid.
Congress has not established that the trader knew anything in advance. The letter is careful about that. But the timing, the size, and the fact that the position was opened on a platform with no mandatory KYC is exactly the combination lawmakers wanted a reason to look at.
I have said before that a $1.1 billion position is not a retail trade. Somebody with that kind of size either had conviction, information, or both. Congress wants to find out which.
The Soldier Who Bet on Classified Intel
The second case in the letters is the one that made this probe exist at all.
In April, a federal indictment alleged that Army Master Sergeant Gannon Ken Van Dyke used classified intelligence about Operation Absolute Resolve, the mission that captured Nicolás Maduro, to place Polymarket bets. The alleged profit was more than $409,000. He has pleaded not guilty.
That case is about Polymarket, not Hyperliquid. So why does it matter here? Because it set the frame. Comer’s public statement said bad actors are exploiting these platforms to profit from nonpublic information. Once that frame exists, any venue where large anonymous bets on real-world events can be placed becomes a target.
Hyperliquid fits. HIP-4 outcome markets exist. BTC and ETH perps respond to policy announcements within seconds. From a congressional staffer’s desk, it looks like the same product with more leverage.
Why Hyperliquid Is Different From Polymarket
The comparison is lazy, and it matters that it is lazy.
Polymarket is a prediction market. You bet on discrete events. Kalshi is CFTC-regulated and runs full KYC. PredictIt is a legacy political betting site. Hyperliquid is a decentralized perpetuals exchange where nobody can freeze your position and nobody asks for your passport.
That last part is the entire question. The letter asks about customer verification. Hyperliquid’s answer is that it does not do any at the protocol level. The front end applies geoblocking, and Hyperliquid Labs can respond about that, but the chain itself is permissionless.
We covered how that structure works in our breakdown of whether Hyperliquid is legal in the US. The core point stands: Hyperliquid Labs is a software company, and the exchange is a network. Congress is writing to the software company and asking it to explain the network.
Compare that to the Bitnomial deal with Kraken, which would route US users through a regulated wrapper. That is the version of Hyperliquid Washington can live with. The permissionless version is the one now getting letters.
What Congress Can Actually Do
A House Oversight letter is not a subpoena, and Comer is not a regulator.
What he can do is create a paper trail. The committee is explicitly weighing whether additional congressional action is warranted. That is code for legislation. If the October 13 responses come back thin, expect a hearing, and expect Hyperliquid to be the name in the headline.
The CFTC is the agency that matters. It has been reviewing Hyperliquid’s US path since the summer, and the Lazarus flows were already a problem for that review. A congressional inquiry into insider trading on the same platform does not help the case.
There is a second-order risk too. CME and ICE have already warned the CFTC and Capitol Hill that decentralized perps could enable manipulation and sanctions evasion. This letter gives those lobbyists a fresh exhibit.
What It Means for Season 3 Farmers
Hyperliquid is my main airdrop farm and my daily trading venue. So I have thought about this from the farmer’s side.
Nothing changes today. Points still accrue, volume still counts, and your wallet is still your wallet. If you are farming Hyperliquid Season 3, keep going.
The longer-term question is whether the permissionless model survives US pressure intact. Three outcomes are possible. Hyperliquid Labs tightens front-end geoblocking and calls it a day. The Bitnomial wrapper becomes the official US door while the DEX stays open elsewhere. Or, in the bad scenario, the team gets pushed into some form of address screening at the protocol edge.
The third one would be a real change to what Hyperliquid is. I do not think it happens. Jeff Yan has been consistent about not compromising the core design, and the validator set is outside US jurisdiction. But I would not build a farming strategy that assumes zero KYC forever.
For the ones who moved over after the Bitget hack, our Bitget vs Hyperliquid comparison still holds. Self-custody beats a hacked custodian. It just comes with a different kind of headline risk.
My Position
Flat on HYPE perps, and I have been since I closed my short on September 15.
I wrote up that trade in the HYPE price support post. It worked, I took it, and I did not chase the reversal. Since then HYPE has traded in a range around $88, with two whales moving about $22 million toward exchanges on September 28. That is not a market I want to be levered in during a regulatory news cycle.
My spot bag is untouched, and the twice-weekly DCA into HYPE continues. Congressional letters do not change the revenue. Open interest crossed $8 billion this month, and the buyback keeps burning. If the probe drags HYPE lower, my DCA just buys more.
The trade I am watching is the reaction, not the news. Headlines like this usually get sold first and bought back within days. If HYPE loses the $80 area on this, I will look at a long. I will post it here if I take it.

Final Words
Congress did not discover Hyperliquid because of a prediction market. It discovered Hyperliquid because a $1.1 billion short beat a presidential announcement by 30 hours, and nobody can say who placed it.
That anonymity is the product. It is why the exchange has $8 billion in open interest and why farmers like me use it every day. It is also why Washington will keep sending letters.
October 13 is the date. Watch what Hyperliquid Labs sends back, and watch how the CFTC reads it.
