Polymarket amid Iran tensions, regulatory warning triggered by $1.2 million profit

On February 28, when a military conflict between the United States and Iran materialized, an unusual trading activity emerged on the prediction market Polymarket. Six wallets took positions just hours before the attack, ultimately making over $1.2 million in profit. This event exposed information asymmetry and regulatory gaps within digital prediction markets.

Suspicious Fund Flows Just Before the Attack

According to research by blockchain analysis firm Bubblemaps, multiple accounts received funds for the first time within 24 hours prior to the attack. These accounts then heavily bought “Yes” shares on the market asking, “Will the U.S. attack Iran by February 28, 2026?” This occurred just hours before reports of explosions in Tehran and other locations.

Notably, one wallet purchased over 560,000 shares at about 10.8 cents each, and after the market settled at $1, received approximately $560,000 in refunds. Another wallet bought around 150,000 shares at roughly 20 cents, also securing six-figure profits.

Common Opaque Structures

Bubblemaps’ visual map shows these six wallets forming a cluster, with traces indicating they were funded through similar routes. According to Polymarket data, all six profiles were newly created in February, with no other trading activity recorded outside this event. In other words, these accounts appear to have been established temporarily, designed specifically to capitalize on this event.

In the February expiry market alone, about $90 million in trades were recorded, and over $529 million in related options were wagered since December. While the $1.2 million profit may seem limited relative to the market’s enormous size, the structure and funding patterns suggest significant issues.

Geopolitical Events and Financial Market Turmoil

The Iran strike also sent ripples through the crypto markets. Bitcoin experienced downward pressure, while crude oil futures on Hyperliquid surged over 5%. These developments indicate a new phase where geopolitical risks simultaneously impact traditional financial markets and crypto markets.

This situation makes clear that prediction markets are not just arenas for information efficiency but can also be sources of insider information leaks that directly generate profits.

Regulatory Authorities Take a Harder Line

U.S. regulators are stepping up efforts to monitor insider trading in prediction markets. The Commodity Futures Trading Commission (CFTC) has already issued enforcement advisories warning that insider trading on event contracts may violate U.S. law. CFTC Chair Mike Seiliger called exchanges the “frontline of defense,” signaling strong regulatory resolve.

Meanwhile, competing prediction platform Kalshi has recently taken action. Two users were accused of insider trading, resulting in trading bans and fines. One was a visual effects editor for YouTuber MrBeast’s “Beast Games,” who allegedly traded based on non-public information about the show’s results. Kalshi imposed a two-year ban and over $20,000 in fines on this employee. In another case, a political candidate was penalized for betting on their own election.

Kalshi, designated as a registered contract market by the CFTC, reports investigating around 200 cases and currently continuing investigations into a dozen or more.

Irony of Self-Serving Insider Markets

The rapid growth of prediction markets also raises new regulatory concerns. When blockchain investigator ZachXBT announced an investigation, other Polymarket users created a market predicting which company ZachXBT would target. The investigation involved Axiom, a crypto platform, where ZachXBT pointed out employees used non-public information to trade.

This structure is highly ironic: markets created to detect insider trading are themselves becoming targets of insider trading, highlighting the fundamental vulnerability of prediction markets. Data from Lookonchain shows that 12 wallets heavily bet on Axiom before the announcement.

Expansion of Prediction Markets and Regulatory Gaps

The rapid expansion of prediction markets like Polymarket is attracting attention as a new mechanism for discovering information in financial markets. However, they also serve as ideal playgrounds for those exploiting information asymmetries. The $1.2 million profit incident suggests these markets hold many opportunities but are growing faster than regulators can keep up.

Latin America’s crypto markets are also expanding rapidly, with transaction volumes projected to reach $730 billion in 2025, up 60% year-over-year. Brazil and Argentina are leading this growth, with stablecoins increasingly used for remittances and cross-border payments. The rising adoption of crypto in emerging markets will further challenge regulatory oversight.

Future Evolution of Prediction Markets and Regulatory Challenges

Despite the CFTC’s tough stance and precedents set by Kalshi, markets like Polymarket continue to grow by exploiting regulatory gaps. Until regulators establish robust enforcement frameworks, incidents of insider profit—such as the $1.2 million event—may persist.

The core purpose of prediction markets is to efficiently aggregate dispersed information and facilitate accurate price discovery. However, the risks of information asymmetry and leakage of confidential data will intensify as markets mature, posing serious regulatory challenges. The Polymarket incident indicates that the ongoing tug-of-war between regulators and market participants is still in its early stages.
