Public’s decision to add Kalshi prediction markets and event data to its AI-powered investing platform is the day’s clearest signal that event contracts are moving closer to the mainstream retail-investing experience. Announced by Kalshi, the partnership places prediction-market information alongside the tools investors already use to research markets—expanding the audience that may encounter probabilities as a form of real-time, market-derived information.
Prediction markets enter the investing workflow
Kalshi says Public has partnered with it to add prediction markets and event data to Public’s AI-powered platform. The move matters because it is not simply another standalone prediction-market launch: it integrates event-market signals into an established investing product.
For market watchers, the key question is how these probabilities are presented and used. Event contracts can offer a fast-moving view of collective expectations around specific outcomes, but they are distinct from conventional securities analysis. Putting them inside an AI-oriented investing environment could make those distinctions—and the quality of the underlying market data—more important than ever.
CFTC spotlights manipulation concerns
The Block reports that the CFTC warned that “mention market” contracts—markets tied to whether a public figure says particular words or addresses a topic—may carry heightened manipulation risk.
That warning reaches beyond one niche contract type. Contracts based on actions that a participant, public figure, or coordinated audience can potentially influence pose a different market-design challenge from contracts tied to independently verifiable external outcomes. The concern is especially relevant as platforms experiment with increasingly granular and culturally immediate market subjects.
The regulatory emphasis is a reminder that prediction markets’ growth depends not only on demand and distribution, but also on whether contract rules resist obvious attempts to manufacture an outcome.
A split-screen view of market activity
The supplied market pulse shows heavy recent Polymarket volume in Seahawks vs. Commanders and Eagles vs. Bears, alongside a Bitcoin price target market. Those are examples of the sports and macro-adjacent categories continuing to command attention, while the biggest listed mover was a tennis matchup market, Porto 2: Max Basing vs Mili Poljicak, down 37 points to 24% Yes.
The contrast is useful: liquidity may cluster in familiar sports and crypto events, while product development and regulatory scrutiny are increasingly centered on how far event markets extend into new information and attention-driven categories.
Why it matters
Public’s Kalshi integration expands prediction markets’ distribution just as regulators focus on contracts most vulnerable to manipulation. The industry’s next phase may be defined less by whether event markets attract users, and more by whether platforms can scale access while maintaining credible, defensible market design.
