When insider trading crashes the crypto party
It’s been quite a week on the legal front of the cryptosphere. Two insider trading cases are simultaneously making headlines in radically different contexts: on one side, Jane Street, the quantitative finance heavyweight, seeking to get rid of an inconvenient lawsuit, and on the other, an American soldier accused of turning classified intelligence into trading gains on a decentralized betting platform. Sometimes fiction can’t compete with reality.
Jane Street vs. Terraform: the legal saga continues
The Terra/LUNA saga, which in 2022 wiped out some $40 billion in market capitalization in just a few days, continues to produce legal consequences. Terraform Labs — or what remains of it after the collapse — had filed a lawsuit against Jane Street, the American algorithmic trading giant, accusing it of precipitating the collapse of its algorithmic stablecoin UST and its associated LUNA token through insider trading operations.
As a reminder, UST was an “algorithmic” stablecoin: instead of being backed by actual dollars, it maintained its peg to the dollar through a complex mechanism involving the LUNA token. A system that showed its limits spectacularly — and catastrophically for investors.
Jane Street, far from being intimidated, has therefore filed a motion with an American court to have the lawsuit dismissed outright. The firm’s argument is rather blunt: the causes of Terra’s collapse have already been extensively debated in other legal proceedings. In other words, “we’ve already tried this case, move on.” A defense strategy that banks on judicial fatigue as much as on the merits of the law.
The outcome of this dismissal request will be decisive. If the court accepts it, Terraform will find itself in an additional legal impasse, while the company is already going through liquidation proceedings after concluding a $4.47 billion settlement with the SEC.
A soldier, classified intelligence, and $400,000 on Polymarket
If the Jane Street case falls within traditional financial law applied to crypto, the second case of the week almost belongs to another genre — call it geopolitical thriller.
According to U.S. federal prosecutors, a military soldier allegedly used classified information to bet on political events via Polymarket, a decentralized prediction market platform. The result? Approximately $400,000 in gains.
Concretely, Polymarket allows anyone to bet on the outcome of real-world events: elections, central bank decisions, political crises… In this specific case, the soldier allegedly wagered on issues related to the situation in Venezuela, particularly on potential developments around President Nicolás Maduro — information he would have had access to through his military duties well before the general public.
This case raises a question few anticipated when decentralized prediction platforms emerged: what happens when someone has an… institutional information asymmetry? Prediction markets are theoretically designed to aggregate collective wisdom. But if a participant possesses data that no one else legally has access to, the equation changes radically.
The soldier now faces federal charges, which could mark an important precedent regarding the use of crypto platforms in matters involving state secrets.
Two cases, one underlying symptom
What connects these two seemingly very different stories is the fundamental question of market fairness. Insider trading — trading based on non-public information — is prohibited in traditional financial markets precisely because it creates an uneven playing field. Crypto, often presented as a disintermediated and more “fair” space, is not immune to this problem.
Whether it’s an institutional player capable of moving entire markets or an individual exploiting government intelligence, the logic is the same: profit from information that others don’t have.
American regulators and courts seem increasingly determined to apply existing principles of financial law to these new playgrounds, whether algorithmic stablecoins or decentralized prediction markets. The crypto Wild West is gradually getting sheriffs — even if some lawsuits risk lasting as long as the collapse they’re trying to explain.
