Insider bet? Wallet linked to Axiom user profits after ZachXBT names exchange

A prediction market bet placed ahead of a high-profile crypto investigation has drawn scrutiny after on-chain analysts linked the winning account to an active user of Axiom Exchange, the platform later named in the probe.

The episode has reignited concerns about information leakage, internal controls at crypto firms, and whether investigations themselves are becoming tradeable events in on-chain markets.

Investigation teased before the reveal

Blockchain investigator ZachXBT first hinted on 23 February that a major investigation into insider trading at a crypto company was imminent. The teaser sparked speculation across social media and prediction markets, but no firm names were mentioned at the time.

On 26 February, ZachXBT published a detailed investigation. He alleged that employees at Axiom Exchange had abused internal tools to access sensitive user wallet data, enabling insider trading and coordinated profit-seeking. 

The report included recordings, screenshots of internal dashboards, and wallet-tracking evidence dating back to early 2025.

Axiom later acknowledged the allegations and said it was reviewing the claims internally.

A profitable bet draws attention

Following the public release, on-chain analytics firm Lookonchain flagged a trader under the username “predictorxyz” on Polymarket. The trader wagered roughly $65,800 on a market asking whether Axiom would be accused of insider trading.

At the time the position was opened, the odds reportedly implied only a 13.8% probability. After Axiom was named in the investigation, the position settled in profit, netting more than $400,000, according to Polymarket data shared by Lookonchain.

The timing raised immediate questions: the bet was placed after ZachXBT’s public tease, but before the exchange was identified.

Lookonchain also reported that two other newly created anonymous wallets bet $59.8K on Axiom being the company. The data showed that these wallets made $109K in three hours.

Wallet traced back to an Axiom user

In a follow-up response, ZachXBT said he had traced the funding source of the Polymarket account. It was traced back through instant exchanges to a Solana wallet linked to an active Axiom user, known on another platform under the username “JustADegen”.

According to ZachXBT, the account was newly created and funded with approximately $70,000 in USDC shortly before the bet was placed. This pattern was described as suspicious, though not definitive proof of wrongdoing.

ZachXBT emphasised that his findings were based on timing analysis and transaction flows. That further confirmation would require access to internal exchange logs. No criminal charges have been filed, and no law enforcement action has been announced.

What the Axiom episode reveals

While the allegations against Axiom remain under review, the sequence of events highlights a broader issue for crypto markets: investigations, leaks, and enforcement actions can now move prices — and prediction market odds — before facts are fully public.

Even without proof of insider coordination, the case illustrates how asymmetric information, or even its perception, can create profit opportunities in on-chain markets. 

It also raises uncomfortable questions for exchanges about employee access to sensitive data and the safeguards in place to prevent misuse.

For prediction markets, the incident underscores a growing tension between open betting on future events and the risk that insiders may exploit privileged knowledge — or appear to do so — in ways that undermine trust.

What happens next

Axiom has not publicly commented on the specific wallet-tracking claims tied to the Polymarket bet. 

ZachXBT has said he hopes the company conducts a deeper internal review and considers legal action against any employees found to have abused their access.

Whether regulators or prosecutors take interest remains to be seen.

But for crypto markets, the episode has already delivered a stark reminder: when investigations themselves become market catalysts, the line between information, speculation, and insider advantage can blur quickly.

Final Summary

• The Axiom investigation underscores how insider access and weak internal controls can turn sensitive information into a financial instrument before the public narrative fully forms.
• As prediction markets intersect with on-chain transparency, exchanges may face heightened pressure to demonstrate that internal data access cannot be exploited before market-moving disclosures.
