Prediction market platform Kalshi has partnered with enterprise compliance software provider StarCompliance to deploy real-time prediction market surveillance across its markets — a move that directly targets the insider-trading risks that have shadowed the sector as institutional money flows in. For traders watching where prediction markets are headed, this deal is a clear signal that the space is shifting from regulatory grey area to regulated infrastructure, and the compliance cost of that transition is only going up.
What Happened
Kalshi integrated with StarCompliance, a firm that specializes in employee trading compliance for financial institutions, to create what the companies describe as an enterprise-grade compliance solution purpose-built for prediction markets. The system lets financial firms connect their employees’ Kalshi accounts to existing compliance infrastructure, enabling automated surveillance of trades across the platform in real time.
The integration goes beyond basic account linking. It layers in configurable alerts tied to firm-defined risk parameters, centralized case management for investigations and audit tracking, and monitoring linked to transaction volume, trading patterns, market categories, and work-hour activity. In plain terms: if a bank analyst is trading Kalshi contracts that could be informed by non-public information they handle at work, compliance officers will now have the tooling to flag it.
The timing is not coincidental. Kalshi has disclosed that it screens for and blocks suspected insider-trading attempts, runs internal investigations, and has referred cases to law enforcement — including cases involving individuals believed to have traded on non-public information tied to their professional roles. The volume of that activity made a structural compliance solution unavoidable rather than optional.
What It Means for Traders
Retail participants may feel the most visible effect of this deal indirectly. As financial firms gain the compliance tooling they need to allow employees to trade prediction markets, institutional participation will likely grow. More liquidity and more professionally managed positions changes the dynamics of any market — spreads can tighten, but edges that relied on retail-dominated order flow may compress as well.
The surveillance architecture also sets a precedent for what “compliant” participation looks like. Firms that want exposure to event contracts now have a tested framework to point to when internal compliance teams push back. That lowers the barrier for institutional adoption, which Kalshi has explicitly been targeting.
For existing active traders, the environment simply becomes more watched. Patterns that flag as unusual in legacy markets — heavy positioning ahead of market-moving events, abnormal trade timing relative to business hours, volume spikes in narrow contract categories — are precisely what this system is built to detect. That applies to employees of regulated firms first, but the framework itself signals the direction of travel for oversight across the board.
The Bigger Picture
The Kalshi-StarCompliance deal lands in the middle of a significant jurisdictional dispute between the Commodity Futures Trading Commission and state regulators over who governs prediction markets. The CFTC has acted to defend federally regulated event contracts against state-level enforcement, and federal courts have sided with Kalshi on preemption arguments in multiple states, finding that CFTC-regulated event contracts likely supersede state gambling laws.
The CFTC has also moved toward a more defined federal framework for event contracts through rulemaking and formal guidance. Against that backdrop, Kalshi’s move to build institutional compliance infrastructure is as much a strategic signal as an operational one — demonstrating that the platform can self-regulate at an institutional standard strengthens the case that federal oversight is sufficient and state intervention is unnecessary.
Polymarket is navigating the same environment. After re-establishing a regulated US presence, it has published updated market integrity rules covering insider trading and market manipulation. The parallel moves by the two largest prediction market platforms suggest that compliance infrastructure is becoming a competitive differentiator, not merely a regulatory checkbox. Platforms that can demonstrate robust oversight gain credibility with both institutional clients and federal regulators at the same time.
Proposed federal rules would also shape the boundaries of what event contracts can legally cover, including potential limits on contracts tied to violent or harmful outcomes. The combination of federal rulemaking, active litigation, and voluntary compliance investment is compressing the ambiguity that characterized prediction markets only a year ago.
Conclusion
Kalshi adding StarCompliance to its stack is less a routine technology announcement and more a declaration of intent: prediction markets are building the institutional plumbing needed to operate inside the regulated financial system, not around it. With the CFTC asserting federal jurisdiction, state-level legal challenges being beaten back in court, and institutional firms requiring enterprise compliance before they can participate, the sector is moving toward a more structured form of market infrastructure. Traders who understand that trajectory will be better positioned to read how liquidity, regulation, and access evolve from here.
