Public and Kalshi partner on AI trading

New York-based investing app Public announced a product letting users deploy AI agents to trade prediction market events. Kalshi, one of the largest prediction markets, provides the contracts and handles trades.

How the AI agents work

Users decide on a strategy and instruct Public's AI what to do. The agent converts requests into fixed rules, from sending alerts when odds change to automatically buying or selling investments. Users must approve rules before the agent acts.

Tracking real-world events

The product targets investors who want to use prediction market data to track events affecting their portfolios, such as Federal Reserve rate decisions, regulatory approvals or company metrics like quarterly shipments.

Why agents matter for investors

Leif Abraham, Public's cofounder and co-CEO, said AI agents can monitor markets when investors are not looking at a screen and execute strategies they might not be physically able to execute themselves.

“AI agents can do work for you, and in investing, that means they can monitor markets when you're not looking at a screen.”

Public's broader strategy

Founded in 2019 and backed by Accel and Tiger Global, Public manages billions in assets across millions of users. The company positions itself as an agentic brokerage, using software to handle routine portfolio work rather than just executing trades.

Prediction markets surge in the US

Prediction markets have surged since the two thousand twenty-four presidential election. Platforms like Kalshi and Polymarket have reached multibillion-dollar valuations, with some contracts generating billions in trading volume across politics, sports and culture.
