Polymarket to Investigate “Insider Copy-Trading” Startup Amid Concerns Over Potential Market Manipulation

According to The Information, prediction market Polymarket has announced audits of several early-stage startups integrated into its ecosystem. These startups had previously been accused of identifying and distributing suspected “insider trading accounts” to steer users into copy-trading those accounts. Among the implicated projects are Kreo—which touts itself as a service for “detecting insider accounts ahead of time”—and Polycool—which offers an “insider trading guide.” By pushing suspicious account trading data to users, these platforms have amplified market concerns about insider trading and market manipulation. Polymarket’s move signals its strengthened compliance oversight of its ecosystem, following sustained external scrutiny over potential insider trading risks in prediction markets.
