How Did Tarek Mansour Create Kalshi?

In 2018, Tarek Mansour teamed up with his MIT classmate Luana Lopes Lara to launch Kalshi. They identified a gap in the financial markets where people could not hedge against real-world risks directly through a regulated and legal exchange platform.

The founders joined the Y Combinator accelerator program to secure initial funding and mentorship. This 3-month intensive helped them refine their business model and build the technical infrastructure necessary to handle high volumes of trades for various retail investors.

Mansour then spent nearly 2 years navigating the complex legal framework of the United States. He worked closely with the CFTC to prove that event-based contracts were not gambling. This persistence eventually led to a historic regulatory approval in 2020.

Today, Kalshi stands as a unique exchange where users trade on everything from weather to politics. Mansour successfully turned a theoretical concept into a practical tool. His leadership continues to drive the platform toward becoming a mainstream financial market staple.
