The latest ZachXBT investigation has triggered major discussion across the crypto market after revealing suspicious betting activity linked to the Axiom insider trading case.
ZachXBT, a blockchain investigator, recently exposed alleged insider trading at Axiom Exchange, where an employee reportedly used internal tools to track user wallets and front-run trades. But the story didn’t stop there.

Things got more complicated when, before the news became public, many people on Polymarket started betting on which company ZachXBT would expose, and the majority of top-gaining wallets made huge profits by betting on Axiom.
This created controversy because it looks like insiders may have used early information about the investigation itself to make money, raising concerns about trust and fairness in prediction markets.
The case investigation began after the on-chain investigator accused Axiom Exchange employee Broox Bauer of misusing internal tools that allowed tracking of user wallets, transaction history, and trading behaviour.

Soon after the announcement came that the investigation would surface on February 26, Polymarket launched a prediction market asking which company ZachXBT would expose.
According to analysis, more than 3,630 addresses participated in Polymarket bets related to the Insider Probe case. Around 56.2% of participants ended up profitable. However, the biggest attention came from the top earners, eight of the top 10 highest-profit wallets showed insider-like behaviour and generated over $1.2 million combined.
This created a controversial situation where an investigation into insiders trading may have triggered another layer of insider-style profits. Analysts noted many suspicious wallets were newly created in February 2026 and had little prior activity beyond this single event.
Polymarket is the largest decentralized prediction market, processing over $50–56 billion in total trading volume with record monthly activity reaching $7.6–12 billion in January 2026 alone. The platform now has around 1.9 million total addresses, with 300,000–600,000 monthly active users.
Because so many people rely on it to reflect real market expectations, but when insider trading concerns appear on a platform this large, it risks discouraging retail participation, raising fairness questions, and weakening confidence in prediction markets as reliable sentiment tools for the broader crypto community.
On the other hand, Axiom Exchange, the Solana-based trading platform, interacted with 650,000+ wallets by mid-2025 and is estimated to have around 300,000 monthly active users. Insider trading in this puts exchanges also under scrutiny.
While blockchain transparency allows anyone to track transactions and wallet activity, it does not guarantee equal access to information. Individuals who receive insights earlier, whether through internal tools, leaks, or private networks, can position themselves before the broader market reacts.
Experts often compare this to traditional financial markets where traders with early or exclusive data can capture disproportionate profits. In prediction markets and crypto trading, this advantage can lead to sudden price moves, unusually profitable trades, and most importantly, damage to the sovereignty of decentralization.
Overall, the ZachXBT Polymarket Insider Probe has intensified debate around prediction market fairness. The incident shows how transparency alone may not prevent insider advantages, pushing the industry toward stronger access controls, monitoring tools, and clearer rules to maintain user trust.
