Rothera has deployed Eventus’ Validus platform to monitor trading on its regulated event-contract exchange, adding surveillance technology already used by brokers, futures firms and established trading venues. The implementation comes as prediction markets handle growing volumes and face the market-integrity obligations associated with regulated exchanges. Rothera is a joint venture between Robinhood and Susquehanna, launched as a designated contract market and registered derivatives clearing organisation overseen by the US Commodity Futures Trading Commission.It launched its first products in May, and its World Cup markets had generated 3.5 billion traded contracts by mid-July, according to the company.Why Event Markets Need Trade Surveillance Validus analyses orders, executions and participant behaviour, generating alerts for compliance teams to investigate. Its procedures seek to identify potentially abusive patterns including spoofing, layering and wash trading, alongside suspicious activity involving particular instruments or accounts. Rothera plans to use the system across fully collateralised and margined products. Event contracts present surveillance demands familiar to other derivatives operators, alongside risks specific to markets settled against real-world outcomes.According to Rothera Chief Compliance and Regulatory Officer Kevin Dan, “a reliable market surveillance partner is foundational to Rothera’s ability to offer customers fair and orderly markets on an Exchange that adheres to CFTC Core Principles.”Compliance teams may need to examine trading by participants who can influence an outcome or possess non-public information, as well as self-dealing, artificial volume and coordinated activity. These are monitoring risks rather than evidence that misconduct is widespread across the sector. External Monitoring Spreads across Event Exchanges Prediction market platforms seek to add third-party surveillance infrastructure. Novig deployed Validus in June, while Kalshi said in February that it would augment its internal systems with technology from Solidus Labs. Validus also supports conventional market participants, including broker-dealer and futures commission merchant PhillipCapital and CFTC-regulated derivatives exchange Bitnomial. Recent exchange enforcement illustrates the conduct these controls are intended to identify. In February, the CFTC described a case in which a political candidate traded a Kalshi contract linked to his own candidacy. Kalshi imposed a financial penalty and suspended the trader for five years because its rules prohibit trading in contracts whose outcomes a participant can influence. The CFTC advisory also covered an editor affiliated with a YouTube channel who likely had access to non-public information before videos were published. After investigating the trades, Kalshi imposed a separate financial penalty and a two-year suspension. Rothera said it needed a system capable of monitoring thousands of event contracts. That requires alert investigation and an audit trail for internal review and regulatory oversight alongside the exchange’s matching and clearing functions. Deployments by Rothera, Novig and Kalshi place third-party surveillance among the core controls being adopted as regulated event exchanges expand their product ranges and trading volumes.This article was written by Tanya Chepkova at www.financemagnates.com.
