Public Brings Kalshi Prediction Markets to Its AI Investing Agents

Public, the brokerage that calls itself the world’s first agentic brokerage, launched AI Agents for Prediction Markets on September 24, 2026, through a partnership with Kalshi, giving members direct access to Kalshi’s event contracts and letting the platform’s built-in AI agents use market-implied probabilities as signals across the rest of a member’s portfolio.

Kalshi announced the partnership on its newsroom the same day, saying Public users will access its event contracts through the same infrastructure they already use for the brokerage’s other financial products. Members can trade events directly or have the AI agents trade on their behalf, and prediction markets are available to all Public members from launch.

Public’s own announcement, datelined New York on September 24, said the company partnered with Kalshi to offer prediction markets and execute trades for members, with a launch focus on events that move the markets. Kalshi is a CFTC-regulated financial exchange, and both companies describe it as the world’s largest prediction market. Kalshi says its markets translate trading activity into real-time, market-implied probabilities for future events, and it describes its data as well-calibrated and as a source for research, investment analysis, and risk management.

“Public is built for investors who take an active hand in constructing their portfolios, and our AI agents let them automate those strategies,” said Leif Abraham, Public’s co-CEO and co-founder. “Prediction markets give those agents a new input: real-world events. Members can take a position on the event directly, or use the market’s data as the signal that triggers a trade anywhere else in their portfolio.”

How the Agents Use Market Data

According to Public’s release, the platform’s AI agents can use prediction market data as a signal for a stock or bond trade, and members can monitor prediction market probabilities and take action in response to changing outcomes. The release lists three example instructions a member could give an agent. In the first, if the probability of FDA approval for a healthcare stock in the member’s portfolio crosses 75%, the agent automatically executes a $5,000 market buy for that symbol. In the second, if the probability of at least three rate cuts this year rises by 10 percentage points in a single day, the agent alerts the member and summarizes the member’s exposure to bank stocks. In the third, if the probability of a Q3 earnings miss rises above 60% for any stock the member owns, the agent buys in-the-money put options while spending no more than $2,500 per position.

Public’s product page says agents act on rules members write in plain English, from sending custom alerts to placing trades, and that the member defines the conditions and actions, then reviews and approves the plan before the agent runs. The page lists three agent functions: automated trading, in which agents buy or sell event contracts when specified market conditions are met; market monitoring, in which agents act when an implied probability reaches a set threshold; and cross-asset automation, in which an implied probability triggers an action elsewhere in the portfolio.

“This partnership broadens how investors can engage with prediction markets and the data they generate,” said Max Crowley, Kalshi’s vice president of business development. Crowley said Public members can use the probabilities Kalshi’s markets produce as a signal alongside stocks, bonds, crypto, and other assets, and that bringing the data into Public’s AI agents shows prediction markets increasingly being used to assess risk, inform investment views, and support trading strategies.

Markets, Access, and Features

Contract categories at launch cover crypto, commodities, climate, economics, corporate events, markets, indices, tech and science, and politics and elections. The companies say each category is designed to give investors another way to assess potential risks and opportunities relevant to their portfolios, citing examples that include evaluating the potential impact of a Federal Reserve rate cut, anticipating bitcoin price movements, and assessing the likelihood of a corporate event.

The product page details tradable markets within those categories: Federal Reserve interest rate decisions, CPI inflation prints, GDP releases, and unemployment numbers; quarterly earnings, vehicle delivery targets, revenue milestones, and corporate headcount changes; court rulings, antitrust case decisions, regulatory approvals such as FDA drug approvals, and legislative actions; presidential and congressional elections, cabinet confirmations, and international policy shifts; and target price levels for major cryptocurrencies, crude oil benchmarks, and precious metals.

Prediction markets on Public trade 24 hours a day, seven days a week, including weekends and holidays, and the page says members can take positions on breaking news and events when traditional markets are closed. Eligibility matches a standard Public brokerage account: members must be at least 18 years old, hold a valid Social Security number and a permanent US residential address, and be a US citizen, permanent resident, or valid US visa holder. Members can trade from their primary brokerage account using existing buying power, or open and fund a dedicated account for event contracts while managing all assets under a single login.

Listed features include an event contracts hub covering the most heavily traded contracts and a member’s owned positions, an AI market briefing on the events moving prediction markets, contextual discovery that places relevant contracts on asset pages with live market-implied probabilities, an integrated watchlist the page lists as coming soon, and API access with a Python SDK that provides read and write access for programmatic prediction market strategies.
