Brokerage firm Public launched AI Agents for Prediction Markets on September 24, 2026, through a partnership with Kalshi, letting members trade Kalshi event contracts directly or have the platform's AI agents trade on their behalf, according to announcements from both companies.
Through the partnership, Public members can access Kalshi event contracts through the same infrastructure they already use for Public's other financial products, Kalshi said in its Sept. 24 newsroom announcement. Members can trade events directly or let built-in AI agents act on their behalf, and the agents can use prediction-market data as a signal for stock or bond trades elsewhere in a portfolio, according to Kalshi.
Public, which describes itself as the world's first agentic brokerage, is positioning the launch around automation. "Public is built for investors who take an active hand in constructing their portfolios, and our AI agents let them automate those strategies," co-CEO and co-founder Leif Abraham said. "Prediction markets give those agents a new input: real-world events." In a Fortune interview, Abraham added: "AI agents can do work for you, and in investing, that means they can monitor markets when you're not looking at a screen. They can execute strategies that you might have not been physically even able to execute yourself," according to a syndication of the interview.
The product keeps the member in the loop at launch. Users set a strategy and instruct the platform's AI, which converts it into fixed rules that can range from sending an alert when probabilities change to automatically executing a trade, and investors must approve the rules before the agent can act, the Fortune interview reported. Public's launch examples included buying a healthcare stock if FDA approval odds move above 75%, or buying put options if the probability of an earnings miss rises above 60%, with an example position cap of $2,500, according to Bonus.com, citing Public's September 24, 2026 launch materials.
Coverage spans the categories that move financial markets. Tradeable events at launch included Fed rate decisions, CPI and inflation releases, GDP, unemployment, earnings results, delivery targets, revenue milestones, regulatory approvals, legislative actions, elections, and price levels for crypto, oil and precious metals, Public said, via Bonus.com. The offering includes an event contracts hub and daily AI market briefings, markets are available 24/7 including weekends and holidays, and developers can reach them through an open API and Python SDK with read and write functionality, according to Bonus.com.
The regulatory wrapper is the differentiator Public is emphasizing. Kalshi is a CFTC-regulated financial exchange, according to both companies' announcements. Event contracts on Public are offered by Open to the Public Investing, Inc. and Apex Clearing Corporation, both registered futures commission merchants, Public said, via Bonus.com. Public's disclosures also state that event contract trading involves significant risk and is not appropriate for everyone, and that event contract accounts are not protected by SIPC, according to Bonus.com.
Eligibility is limited at launch. Public said the product is available to eligible members who are at least 18, hold a valid Social Security number, have a legal permanent U.S. residential address, and are U.S. citizens, permanent residents or valid visa holders, according to Bonus.com. Kalshi said prediction markets are now available to all Public members. "Bringing this data into Public's AI agents shows how prediction markets are increasingly being used to assess risk, inform investment views and support trading strategies," said Max Crowley, Kalshi's vice president of business development.
