Something very strange happened at Polymarket last week, and people are starting to notice. When ZachXBT announced that Axiom would be the target of his insider trading investigation, it seemed like a small group already knew exactly what was going to happen.

Let me explain the context: Polymarket created a prediction market weeks earlier, allowing users to bet on which company would be named. This attracted around $40 million in volume since Monday. Normal, right? Wrong. When we look at on-chain data, it’s clear that a small group of newly created anonymous wallets heavily bet on Axiom just before the reveal happened.

The numbers are impressive. Lookonchain identified 12 wallets that collectively accumulated over $1 million in profits. But there’s more: a data terminal called Polysights found five wallets that bet about $50,000 and walked away with $266,000. The biggest individual bet? An account called predictorxyz bought 477,415 shares at $0.14 and now has a profit of $411,000 — a 7x return.

The pattern is very suspicious. It wasn’t a dispersed market with many people guessing. A small group of addresses really dominated the Axiom side of the order book. For most of the week, another company called Meteora was leading with over 50% probability. Things only changed at the end of Wednesday, when Axiom hit 46.2% chance.

Now, ZachXBT has already admitted that he contacted Axiom for comments and conducted interviews before publishing. This means people inside the company knew the investigation was coming out. Any of them could have bet directly or leaked the information to someone who did.

The problem? Polymarket doesn’t require identity verification. Without cooperation from the platform itself, tracking who actually made these bets is nearly impossible. Axiom said they are “shocked and disappointed” and will investigate, but they didn’t respond if their employees were trading on the market.

The most ironic part is that the mechanism worked exactly as designed — a small group benefited from non-public information. But instead of catching the insider traders, it ended up rewarding exactly the people who were the subject of the investigation. It’s like a game where the target gets to see the cards before playing.
