Hedgebook launches S&P 500 hedging app using Kalshi prediction markets
In brief
- Hedgebook connects ~500 S&P 500 companies to 47 Kalshi event contracts via hedgespx.com
- Platform tracks recession probabilities, CPI prints, and macroeconomic indicators for risk assessment
- Event contracts offer binary exposure without options Greeks or implied volatility complexity
- Kalshi raised $1B in May 2026, valuing the CFTC-regulated exchange at $22B
How it works
Hedgebook, accessible at hedgespx.com, establishes roughly 2,500 connections between those 500 companies and Kalshi's 47 distinct markets. The platform tracks recession probabilities, CPI prints, and other economic indicators — events that directly move large-cap stock valuations. Investors can then see which macroeconomic outcomes pose the biggest risks to their positions and explore hedging strategies without leaving the interface.
The appeal lies in simplicity. 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. For portfolio managers accustomed to option chains, this directness cuts through layers of calculation.
Kalshi's momentum
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 carries no cryptocurrency assets or digital tokens.
The platform's institutional footprint expanded sharply in 2026. Kalshi raised $1B in May 2026, reaching a valuation of $22B. In February, it formed a partnership with Game Point Capital to enhance institutional adoption for sports hedging.
The tradeoff
Liquidity in some Kalshi markets remains thinner than what you'd find in major options chains. This matters for large positions. A hedge that can't be executed quickly or at tight spreads loses its protective value.
There have been no recent public announcements or press communications surrounding Hedgebook's launch, which speaks to the quiet, institutional nature of the rollout. Hedgebook isn't marketing to retail traders. It's building infrastructure for portfolio managers who need cleaner, more transparent hedging mechanics than options offer.
