Blockchain sleuth ZachXBT identified crypto trading firm Axiom in an insider-trading probe after at least 12 wallets placed concentrated bets on a Polymarket contract prior to the report going public. Those wallets combined to net over $1 million in profit; the largest account, predictorxyz, bought 477,415 shares at ~$0.14 and is sitting on about $411,000 profit. Polysights and Lookonchain flagged additional suspicious activity (five wallets turning ~$50,000 into $266,000). Polymarket’s contract saw roughly $40 million in volume and attribution is difficult because the offshore platform does not perform identity checks. Axiom said it was “shocked and disappointed” and is investigating.

The story documents concentrated pre-report bets that realized over $1M in combined profit and shows substantial contract volume (~$40M), while Polymarket’s offshore, no‑KYC setup makes attribution difficult; those facts damage platform integrity and could influence short-term trading sentiment.
