Here’s a question most equity investors have asked themselves at least once: what happens to my portfolio if the next CPI print comes in hot, or if a recession officially starts? Hedgebook is betting there’s a middle path, one that runs through prediction markets.

The platform, accessible at hedgespx.com, connects approximately 500 S&P 500 companies to 47 event contracts on Kalshi, the CFTC-regulated prediction market exchange. The idea is straightforward: if you hold large-cap equities, you should be able to see which macroeconomic events pose the biggest risks to your positions, and then explore hedging strategies using Kalshi’s event contracts.

How Hedgebook actually works

Hedgebook has established roughly 2,500 connections between those 500 companies and 47 distinct Kalshi markets as of May 30, 2026. The types of events it tracks include recession probabilities, CPI prints, and other economic indicators. The platform pulls data from the Kalshi API and refreshes daily.

One important distinction: Hedgebook is not a trading tool. It’s a user interface for conditional risk management. It helps you understand your exposure and identify potential hedges, but you still need to go to Kalshi to actually execute trades.

Kalshi’s massive growth provides the foundation

Kalshi was founded in 2018 by Tarek Mansour and Luana Lopes Lara, both MIT alumni. It became the first CFTC-regulated Designated Contract Market for event contracts when it launched publicly in July 2021. Unlike crypto-native prediction markets such as Polymarket, Kalshi operates under federal oversight as a regulated exchange and is not linked with cryptocurrency assets or digital tokens.

The platform raised $1B in May 2026, reaching a valuation of $22B. In February 2026, it formed a partnership with Game Point Capital to enhance institutional adoption for sports hedging.

What this means for investors

Event contracts offer direct, binary exposure to specific outcomes — questions like whether GDP growth will exceed 2% next quarter or whether the Fed will cut rates in September — without the Greeks and implied volatility math that make options complex. Hedgebook’s value proposition is making those connections explicit: if you own a basket of tech stocks, the platform can show you which macroeconomic scenarios represent the greatest downside risk and which Kalshi contracts might serve as hedges.

Liquidity in some Kalshi markets remains thinner than what you’d find in major options chains. There have also been no recent public announcements or press communications surrounding Hedgebook’s launch, suggesting it is an actively maintained interface rather than an entirely new product.
