Eight insider-linked wallets captured $1.2M in profits, mostly from single-market bets placed before odds shifted.
On-chain data has intensified scrutiny around a Polymarket event linked to a ZachXBT insider probe. Trading records show heavy profit concentration among a small cluster of wallets. Several accounts placed large wagers early and exited with six-figure gains.
Concentrated Profits Raise Insider Concerns in ZachXBT-Linked Trade
More than 3,630 Polymarket addresses placed bets on “Axiom” during the incident. Data shows 56.2% of participating wallets ended in profit. While overall participation was broad, gains were heavily concentrated among a handful of accounts.
Eight of the top ten highest-profit addresses can be classified as insider-linked, according to the investigation. Combined profits among those eight wallets exceeded $1.2 million. Most followed a similar pattern, placing very few trades and focusing on a single market.
Trading records show several wallets made a single bet on the ZachXBT market and did not participate elsewhere. Despite minimal activity, three addresses posted profits above $100,000. Wallet “predictorxyz” earned $411,600, while two others captured $354,000 and $144,000.
Researcher defioasis.eth reported that all three six-figure winners traded only that one prediction market. Most active traders usually spread money across several markets to manage risk. Focusing on a single event has therefore raised concerns.

Meanwhile, Lookonchain reported that predictorxyz placed a $65,000 bet when Axiom odds were just 13.8%. Those odds implied a low chance of winning at the time. Betting a large amount under those conditions suggests either very strong confidence or early information.
ZachXBT also flagged a $70,000 USDC deposit into a newly created account shortly before trading began. Creating a new wallet and funding it with a large sum right before placing a winning bet has added to suspicions.
Six-Figure Losses Surface as Axiom Bet Fallout Deepens
Beyond the top winners, dozens of other traders also recorded solid gains. Forty-seven addresses earned between $10,000 and $100,000 each, with combined profits reaching $1.34 million. Even so, most of the largest returns remained concentrated among a small group of leading wallets.
On the losing side, fewer traders were affected, but losses were meaningful. Two addresses each dropped more than $100,000, for a combined $366,000 in losses. Another fifty wallets posted losses between $10,000 and $100,000, totaling roughly $1.24 million.
Trading results follow a familiar pattern, as traders who entered early secured most of the gains. Later participants took most of the losses. Most gains went to wallets that traded only this single event, which has increased concerns about possible insider access.
So far, Polymarket has not released an official response. Growing attention may push prediction platforms to tighten monitoring, especially when new accounts deposit large sums and place big bets in low-liquidity markets.

“Sports Betting Contract” is a derivative! The U.S. CFTC blocks local law enforcement to fight for regulatory control of prediction markets
The U.S. federal government argues that sports event wagering should be treated as a financial derivative rather than gambling, and it seeks to bar Arizona from enforcing against Kalshi, the prediction market platform. If the court backs the federal position, prediction markets will operate under uniform nationwide regulation, weakening each state’s ability to regulate. This legal dispute concerns the legitimacy of prediction markets and the allocation of regulatory authority, affecting the future development of the industry.

Bitcoin Breaks Through $72,000: The Iran–Israel ceasefire boosts risk assets, with $427 million in short positions liquidated, but Polymarket shows disagreement on end-of-year outlook
Bitcoin broke through $72,000 on April 10, mainly due to a fragile ceasefire agreement between the U.S. and Iran that boosted market risk appetite, with funds flowing from safe-haven assets into Bitcoin. Increased institutional inflows and a rebound in Large Investors’ holdings are driving the price higher. Technical analysis shows that the main resistance lies in the $72,200 to $73,500 range. Despite a bullish outlook in the short term, there is still disagreement over forecasts for Bitcoin’s price by year-end, and the risk of a pullback also needs to be watched.
