Public launches AI agents for prediction markets with Kalshi

Public, calling itself the world's first agentic brokerage, announced AI Agents for Prediction Markets. Members can trade event contracts directly or have Public AI agents use prediction-market data as a signal for stock, bond, or options trades. Public partnered with Kalshi, a CFTC-regulated prediction-market exchange, to offer the markets and execute trades.

FINANCE desk — when brokers wire prediction-market odds into agents that can buy stocks and options, event betting stops being a side game and starts steering real portfolios.

What the lede says the product is. Public calls itself the world's first agentic brokerage, and says it launched AI Agents for Prediction Markets so members can trade on events that can shape financial markets and connect them with the rest of their portfolio. People can trade events directly or have AI agents trade on their behalf. The example in that same paragraph: Public's AI agents can use prediction-market data as a signal for a stock or bond trade. A prediction market, in plain words, is a market where you trade on whether a future event happens. An agentic brokerage, here, means AI agents that can act inside the portfolio under rules the member sets. World's first is the company's claim. This desk did not survey every brokerage. The lede's signal example is a stock or a bond. It does not say options. Options show up later, in an example and in the about box. Do not collapse those sentences.

What members get, in the next paragraphs. Members will have access to a broad range of prediction markets across key areas of the economy and financial markets, and will be able to use AI agents to make informed decisions based on prediction-market data. The launch introduces prediction markets to Public, with a focus on events that move the markets. Categories at launch include crypto, commodities, climate, economics, corporate events, markets, indices, tech and science, and politics and elections. The page prints "tech & science." Each category, the release says, is another way to assess potential risks and opportunities in a portfolio. The illustrations it names are the potential impact of a Federal Reserve rate cut, bitcoin price movements, and the likelihood of a corporate event. A Federal Reserve rate cut is a decision by the U.S. central bank to lower its policy rate. Those three are examples of what the categories are for. They are not a list of live contracts this desk traded.

The co-founder's sentences, as a quote. Leif Abraham, identified as Co-CEO and Co-Founder of Public, said Public is built for investors who take an active hand in constructing their portfolios, and that the AI agents let them automate those strategies. He said 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. Co-CEO means he shares the chief executive job. That is his sentence on the wire. A quote is not a track record. This desk did not interview him.

Three instructions the release prints, and only those. Members can use the agentic brokerage and the AI agents to monitor prediction-market probabilities and take action when outcomes change. The release says members could instruct their agents to do three things. First, act on a clinical trial or a regulatory outcome: if the probability of FDA approval for a healthcare stock in the portfolio crosses 75 percent, automatically execute a $5,000 market buy for that symbol. FDA is the U.S. Food and Drug Administration, the agency that clears a drug. A market buy is an order that takes the price on offer now, not a limit the person names. Second, monitor rate expectations: if the probability of at least three rate cuts this year rises by 10 percentage points in a single day, alert the member and summarize exposure to bank stocks. Percentage points are the release's unit. Ten percentage points is not the same phrase as ten percent. "This year" is the release's clock, on a wire dated 24 Sep 2026. Third, respond to earnings risk: if the probability of a Q3 earnings miss rises above 60 percent for any stock the member owns, buy in-the-money put options, spending no more than $2,500 per position. Q3 is the third quarter. A put option is a contract that gains value if the stock price falls. In the money means the option already has value at the current price. These are examples on the page. This desk did not send an instruction, buy a stock, or buy a put.

Who provides the markets. Public partnered with Kalshi, which the release calls the world's largest prediction market and a CFTC-regulated financial exchange, to offer prediction markets and execute trades for members. CFTC is the U.S. Commodity Futures Trading Commission, the federal regulator for futures and for many event contracts. World's largest is the release's description of Kalshi. This desk did not measure Kalshi against other venues, and it did not read a CFTC order. The partnership sentence is about offering the prediction markets and executing trades. It does not, by itself, say Kalshi clears the stock order or the put in the examples above. Those examples sit in the agent-instruction list. Do not merge them into one venue.

Who can use it, and what the about box says the company is. Prediction Markets are now available to all Public members. The release says to join at www.public.com. The about box calls Public the world's first Agentic Brokerage, with a capital A and a capital B. The lede's phrase is "world's first agentic brokerage," in lowercase. Same claim, two casings. Investors, the about box says, use AI and a vast variety of asset classes, from stocks and bonds to crypto and options, to build portfolios for the long haul. Options are on that list. They are not in the lede's stock-or-bond example. Launched in 2019. Trusted with billions in assets of affluent investors. The page does not print a dollar figure for those billions. Headquartered in New York City. It has raised funding from investors like Accel and Tiger Global. "Like" means those two are examples the page names, not a full list of every investor. These lines are the about box. This desk did not audit assets under management.

What the picture shows, and what the words do not. The release graphic is two phones of Public product UI. The left phone is a prediction market under a Fed label, titled "Number of rate cuts in 2026?", with listed outcomes, a cent price and a percent on each line, a chart, and a volume figure. The right phone is the Build an agent screen: "Create an agent for your portfolio," a box to define a task, and sample tasks, including one labeled CPI hedge and one labeled idle cash management. Beside the phones, the graphic shows a "Trade placed" chip and two ABOVE price chips. CPI, on that card, is the consumer price index, the common measure of inflation. The cents, the percents, the volume, the sample-task wording, and the chip prices are the graphic's. The release text does not print them. The caption under the graphic is "Prediction Market from Public." Do not treat the still as a book of prices this desk traded, and do not treat a dollar figure on the still as the $5,000 in the FDA example. Those are different sentences.

Plain English for the rest of the card. A prediction market is a trade on whether a future event happens, such as how many times the Fed cuts rates. An event contract is this desk's plain name for that trade. The release's words are prediction markets and trade events. It does not print "event contract." An agentic brokerage is a brokerage where AI agents can act inside the portfolio under the member's rules. A signal, here, means the odds are an input that can trigger a stock, bond, or options trade somewhere else in the account. The lede's own example of that signal is a stock or a bond. The earnings example is a put. The about box lists options as an asset class. CFTC is the Commodity Futures Trading Commission. FDA is the Food and Drug Administration. A market buy takes the current price. A put gains if the stock falls. In the money means it already has value at today's price. Q3 is the third quarter. Ten percentage points is the rate-cut alert's unit. 75 percent, $5,000, 60 percent, and $2,500 are the three examples' numbers. 08:17 ET is 8:17 a.m. Eastern, and 12:17 UTC. 2019 is the year the about box says Public launched. Billions is the about box's word, with no dollar figure beside it. Accel and Tiger Global are the two investors the about box names. This filing is that launch. It is not a trade this desk placed.
