Today weāre launching markets on Business Sector KPIās.
Kalshi originally launched KPI markets to provide investors with direct exposure to the underlying events that move stocks.
If you had a thesis on Teslaās Q4 car deliveries, instead of just buying or shorting the stock as a proxy, these markets enabled you to trade directly on the number of deliveries.
But what if your thesis isn't about a single company, but rather a broader, sector-wide trend?
If you are bullish on the adoption of robotics, delivery apps, or content streaming, you could buy a basket (ETF) of individual stocks in each sector, but in doing so, you become exposed to the external variables that influence stock prices.
Our new Sector KPI markets enable users to trade on aggregated performance.
For example, if you have a view on the mobile adoption of AI, you can now trade on the combined monthly downloads for Claude, ChatGPT, Gemini, and Grok.
We have KPI markets for aggregated credit card spend, point of sale data, and foot traffic, with more to come.
These markets offer a new way to express an opinion and, of course, hedge risk.
Turns out weathermen are just making it up as they go. Kind of crazy how much more accurate prediction markets have become.

From SpaceX rocket engines to Tesla parts, tungsten is the metal that stops everything from melting.
Giving companies a way to lock in prices on Kalshi after a 500% spike is huge for real-world tech.

Every Tesla, every Starlink dish, every rocket on the pad. All of it needs tungsten. Itās in chips, jet engines, drones, missiles, and armor-piercing rounds.
It's in everything America is trying to build. China controls most of the worldās supply. Prices are up 500%+, including a 94% spike in six weeks this spring.
Oil has futures. Gold has futures. Copper has futures. Tungsten had nothing. So we built it.
Through @PillarHQ, an Ohio metals distributor locked in protection against tungsten prices on Kalshi. A real American business, hedged against a geopolitical supply shock, on a market that didnāt exist until now.
