Kalshi is defining a new category
Kalshi has defined a new category: prediction markets. Kalshi allows people to trade on the outcome of any events & turn any question about the future into a financial asset. Kalshi fought for years & legalized prediction markets in the US for the first time in history. Kalshi is currently the fastest growing financial market in America, & has thousands of markets across politics, economics, financials, weather, tech, AI, culture & more.
We believe prediction markets have the potential to be the largest financial market because they turn anything into a financial position.
Building a new category is hard like really hard. But its beautiful & deeply fulfilling. Our culture is simple: we hire really talented people, work really hard, & enjoy the climb. We are looking for ambitious & exceptional people to join our (relatively small) team to help us build the next generation of financial markets.
