while the plebs are crying in the comments about gambling - prediction market has to be the grittiest business to start, maybe ever due to regulatory at the time these guys will go down in history books as legends, among the likes of the Ellisons, Zuck, etc
Kalshi just raised an additional $1B, valuing the company at $40B. This will help us expand into stocks, compute, indices, and institutional. Tomorrow marks 8 years since we got accepted into YC and the journey began. The odds of a kid from Lebanon getting here were pretty low. Growing up there was great, but very challenging. We went through war. We had bombs explode in front of my house. I watched brilliant people’s lives destroyed for reasons beyond their control. Lebanon is an unpredictable country. That unpredictability made it hard to plan for success. And yet despite it all, my mom sacrificed everything to give me and my brother the chance to go back to the US. I found my refuge in two things: anime and math. Especially math. I loved math because it calmed me. It was the opposite of unpredictable: clear, deterministic, orderly, and consistent. The proof is either right or wrong. I find that elegant and beautiful. I was lucky. I made it to my dream school, MIT (largely thanks to my mom), and my love for math quickly translated to a love for statistics, probability, and markets. I love markets for a lot of the same reasons. Their incentives are clear: you get rewarded for being right and for pursuing knowledge. They are effective weighting machines for people’s opinions. They provide an incentive to be truthful, because they separate good information from bad information. They let people challenge the consensus and be rewarded for being right. IMO, Hayek, Surowiecki, Hanson, Tetlock were the founding fathers of prediction markets. The more I read them, the more obsessed I got with the idea of applying market-based pricing to more things. Markets bring rigor and critical thinking to more questions. And in an increasingly polarized and information-positioned word, I believe we need that more than ever. Markets would also let people predict and manage more things outside of their control. And the world was becoming increasingly more unpredictable, and more like Lebanon, not less. That love for markets got Luana and me to build Kalshi. At first, it was mostly an idea we couldn’t stop talking about. We didn’t have much money. Luana’s sister bought the Kalshi domain name for us (for ~$1.7k). We moved to SF to get started, and embarked on a long, uncertain journey to build a regulated exchange. The paranoia and anxiety from my childhood never left me. Even when things are going well, I think about what could go wrong. When people trust you with their money, that instinct serves a purpose. I wanted us to build something that would hold up under pressure. The first principle we defined at the company: regulatory-first. We worked with regulators for years before we listed a single market. We took every step to do things the right way and always asked for approval before proceeding. It was very hard at times, especially when we were being overtaken by competitors, but we believe doing things the right way matters. Luana and I aren’t the only ones. Our team put years of their lives into something far from certain. That’s especially true of Lior, Brandon, Rainer, Luis, Xavier, and Josef, who stuck with us for years. They believed when there was little to point to. And they stuck with us no matter how long it took. Kalshi is the result of an arduous journey through a long desert where, at times, most people didn’t understand why we were making the walk. Many people still don’t understand what we’re doing and some disagree with us. Markets have historically taken time to be understood and accepted by some. But while not always obvious, their benefits are vast: capital markets help allocate capital and derivative markets help predict and manage uncertainty. I firmly believe in these benefits, and that’s why I am dedicating my life to building this market. Markets have caused issues many times in the past, and they certainly can present harms (manipulation, insiders, and addictive behaviors). These harms are more acute for certain types of markets (sports, short-term options, etc.) than others. It’s why I believe that guardrails need to exist and why we have taken the approach we have taken. We have consistently prioritized thinking critically about the risks and building the appropriate safeguards, sometimes beyond what the regulators require us to do. Many believe more needs to be done, and that’s a conversation I welcome. Over time, I believe more people will see what we see: markets can help us get smarter and manage the future with more rigor, more precision, and more certainty than we have today. To our tens of millions of users: you have made Kalshi bigger than anything Luana and I could have possibly imagined. Thank you for trusting us and thank you for coming along on the journey. I feel a strong responsibility to build a company worthy of that trust. I am so lucky to spend my life building something I love. I hope everyone finds something they care about that much. Something that keeps you curious. Something that pushes you to your limits. Something that may put you at odds with the status quo. Something worth the hard days. For me, it’s still markets. The more I learn, the more I want to understand.

Congress created a federal framework for derivatives markets. Allowing states to impose conflicting rules will undermine that system. Utah is trying to set a dangerous precedent…

Kalshi institutional accounts: 130 → 822 in 10 months. 242 now trade $1M+/month. At FIX today I asked: when do we hit 10,000? The answer I got: hard to say, since every major player that onboards brings hundreds of institutions with it, but it could happen by the end of 2027!

Small businesses are starting to use prediction markets to hedge tariffs, shipping costs, and bad weather. Tea company Zest used a prediction market payout to help offset tariff-related lost sales. Its founder also helped develop a contract that pays when container shipping costs exceed certain thresholds. Other businesses are experimenting with weather contracts to hedge canceled kayak trips, slower ice cream sales, and crop damage. Prediction markets are leveling the playing field for small businesses.

FWIW, I – like scholars ranging from Philip Tetlock to Kenneth Arrow to Daniel Kahneman – believe that there are positive externalities to prediction markets (more widely available accurate information, the ability to hedge against future events, e.g.), and that they work differently than actual betting markets. That doesn’t mean people can’t and don’t abuse them. But people do the same with day trading, and that doesn’t mean the stock market is the same thing as DraftKings.
