Polymarket insider trading fears grow, Bloomberg reports
Bloomberg's Denitsa Tsekova reported on Bloomberg Open Interest that insider trading concerns on Polymarket are becoming more visible, with prediction market participants raising alarms about potential misuse of non-public information on the platform. The segment examined these growing fears without citing specific cases or regulatory actions. Separately, an NBC affiliate site published a headline warning that prediction markets create opportunities for unregulated insider trading, referencing Polymarket in a photo caption showing people wagering on potential Democratic presidential candidates. Neither report detailed specific enforcement actions or platform responses.
Polymarket must now demonstrate its surveillance can detect confidential-data exploits before DOJ and CFTC treat the platform as a co-defendant. Any gap leaves the CFTC-registered exchange exposed in future parallel enforcement actions.
Polymarket joins Kalshi in facing public scrutiny over insider-trading controls after both CFTC-registered platforms tightened surveillance systems this month in response to DOJ-CFTC coordination.
