How Did Polymarket's Mysterious Account Precisely "Front-Run" Before Trump's Post?

A cloud of suspicion over “insider trading” related to war and peace is intensifying on Polymarket, the world’s largest prediction market.

This Monday (March 23), former U.S. President Donald Trump made a high-profile post on Truth Social, claiming that the U.S. and Iran had engaged in “very good and productive talks” to end the Middle East conflict, and announced a five-day pause on strikes against Iranian power facilities. This explosive news quickly triggered a global financial market frenzy—oil prices plummeted, and stock index futures soared. However, even faster than the market reaction, a group of mysterious accounts lurking on Polymarket had already heavily bet that “U.S. and Iran will reach a ceasefire next week” hours or even days before Trump’s public statement.

Is this “divine foresight,” or is it “insider trading” crossing a red line? As public opinion heats up, Polymarket urgently updated its market integrity rules, and members of both parties in the U.S. Congress jointly moved to impose regulations on this rapidly evolving industry.

1. Precise “front-running”: Mysterious 10 accounts with million-dollar gains

● According to on-chain data tracking, at least 10 recently created accounts have shown remarkable “foresight” in Polymarket’s “U.S.-Iran Ceasefire” market. These accounts predominantly bet that a ceasefire would be reached by March 31 or April 15, with a total wager of about $160,000. If the ceasefire occurs before the end of March, these bets could potentially yield over $1 million in profit.

● The timing of these accounts’ positions is extremely sensitive. Most entered the market around March 21, before Trump made any signals about a ceasefire, when the implied probability was only about 6%. This means these traders had to bet heavily in a low-probability fog, going all-in against the odds. After Trump’s post, unrealized gains from these positions instantly increased by over $300,000.

● Even more striking is that these accounts are not “newbies.” One account named “NOTHINGEVERFRICKINGHAPPENS” is considered a “fortune-teller.” It was created at the end of February, with its first two trades betting $7,600 on U.S. strikes against Iran before February 28, and $11,283 betting on strikes before March 1.

These two trades earned the account over $85,000 in profit. Now, this account has again made a precise bet on a ceasefire, and its history has led outsiders to speculate about its source of information.

2. Insider trading or “cash power”? On-chain traces reveal suspicious points

Faced with such precise timing ability, crypto market analysts and detectives on X (formerly Twitter) quickly launched investigations. Ben Yorke, a former researcher at CoinTelegraph, analyzed these accounts’ on-chain behavior and pointed out that these trades exhibit strong signs of insider trading.

The main suspicions focus on two points:

1. Wallet splitting: These accounts appear to have used a “wallet splitting” strategy, dispersing large sums into multiple newly created wallets for betting. Yorke noted that this approach usually indicates either large funds trying to avoid market impact or efforts to obscure true ownership.

2. Reckless position building: These accounts did not adopt a gradual, exploratory approach but instead rushed to bet near market prices or even at market price, fearing to miss the window. This urgency resembles someone with insider information racing against time.

Beyond on-chain suspicions, similar anomalies have appeared in traditional financial markets. Reports indicate that 15 minutes before Trump’s post, about 6,200 crude oil futures contracts changed hands on the NYMEX, with a notional value of approximately $580 million; at the same time, trading volume in S&P 500 mini futures spiked abnormally. These prediction market “front-runners” and futures market anomalies echo each other, fueling speculation about insiders leaking information early.

3. Platform “tightening”: Polymarket updates insider trading rules

Under pressure from public opinion and regulatory risks, Polymarket responded swiftly. On March 23, it announced a comprehensive update to its market integrity rules and launched a dedicated “Market Integrity Page.”

The new rules clearly define three core red lines:

● Prohibition of trading based on stolen confidential information: No trading using illegally obtained insider info.

● Prohibition of trading based on illegal insider tips: No building positions using insider info passed through unauthorized channels.

● Ban on influence by capable entities: Anyone capable of affecting event outcomes (e.g., executives, policymakers, athletes) cannot participate in related contracts.

Polymarket’s Chief Legal Officer Neal Kumar stated, “Market prosperity depends on clear rules. Strengthening these rules clarifies our expectations for all participants.” Analysts suggest this move may signal Polymarket’s intention to follow competitors like Kalshi and conduct formal investigations into these suspicious accounts.

4. Regulatory crackdown: Bipartisan efforts threaten prediction markets

● If platform self-regulation is “patching the hole,” then legislative actions from Congress are the real “pulling the rug.” While Polymarket faces insider trading controversy, Senators Adam Schiff (Democrat) and John C. Cuttis (Republican) jointly introduced a bipartisan bill to ban prediction markets from offering contracts related to sports.

● This classification would be a fatal blow to the industry. Recently, many new prediction market trades have been in sports events. If the bill passes, it would severely damage Kalshi’s business model and block Polymarket’s expansion into sports.

● Meanwhile, state-level regulatory clampdowns are intensifying. Several states have already classified Kalshi and Polymarket as “sports betting platforms disguised as tech,” and are taking legal action to restrict them. Although the current U.S. Commodity Futures Trading Commission (CFTC), under the Trump administration, tends to prioritize federal law over state law, growing bipartisan concern over “war and death” prediction contracts puts prediction markets in a precarious position—caught between financial, gambling, and insider trading regulations.

5. AiCoin perspective: Transparent on-chain data leaves “foxes” nowhere to hide

In this “U.S.-Iran Ceasefire” insider trading suspicion, on-chain transparency has become key to exposing issues. This is where AiCoin’s platform excels.

AiCoin’s built-in Polymarket data dashboard provides real-time on-chain transaction monitoring, wallet fund flow tracking, and anomaly alerts. In this game of war and peace, ordinary investors relying solely on delayed news often become “bagholders.” With AiCoin, users can:

1. Pierce the anonymity veil: Use AiCoin’s on-chain analysis tools to track large wallet holdings and timing of position building, identifying behaviors like the concentrated accumulation seen in this case.

2. Monitor market depth: Observe buy/sell order changes on key event contracts to help determine whether capital inflows are from retail traders or insider/large players “front-running.”

3. Detect early warning signals: Combine AiCoin’s real-time news and on-chain monitoring to receive alerts when implied probabilities shift, rather than reacting only after news breaks.

As of press time, the implied probability of a ceasefire before March 31 on Polymarket has surged from 6% to 24%, with total bets exceeding $21 million. Regardless of the final outcome of this high-stakes gamble, it has already left a profound lesson for this emerging industry: in a world of absolute transparency on the blockchain, there are no secrets forever—only stricter regulation and smarter tools. For investors, instead of blindly following “mysterious accounts,” leveraging professional tools like AiCoin can help find your own certainty amid the fog of information.
