Markets 😍💫
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.

Rizzo's Bar & Grill, steps from Chicago's Wrigley Field, usually has a full house when the Cubs have games.
It can be difficult for owners to plan around the volatility of a postseason, where a team could go on a long run or be quickly eliminated.
Enter prediction markets.

“For 68 years, onions have been the only crop Congress decided Americans couldn’t be trusted to hedge. Not oil. Not wheat. Not pork bellies. To the growers who have gone without a hedge since the Eisenhower administration: we see you."

"Historically, America has frowned on monopolies and protected free-market competition. Why drop this principle for the sake of the gaming industry?"

Yes, a bet and a trade often look similar.
But how they work is fundamentally different.
A sportsbook sets the odds and takes the other side of your bet. Prediction markets are markets, where buyers and sellers compete to discover and produce efficient prices and enable important public benefits.
What the market is about can change, but the structure doesn't.

The clearest explanation I’ve seen of the difference between prediction markets and sportsbooks.
Amazing how much of the media still fails to understand the basic mechanics.

Every Tesla, every Starlink dish, every rocket on the pad. All of it needs tungsten. It’s in chips, jet engines, drones, missiles, and armor-piercing rounds.
It's in everything America is trying to build. China controls most of the world’s 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 didn’t exist until now.

"Oftentimes, they work more like insurance. And prediction markets are opening this protection to businesses with risks that conventional financial markets have struggled to cover," writes @CatoInstitute's @MrRBourne. More in @NRO: nationalreview.com/2026/10/p…

Kalshi’s decision to put regulation before growth looks obvious now. It looked a lot less obvious when they were spending years on it without much to show on a chart.

An LA hospitality group runs 25 bars, many of them right by Dodger Stadium. Every extra playoff game means packed bars. An early exit means lost revenue they were counting on.
So they hedged it. They put $60,000 on Kalshi on the Dodgers *not* making the World Series.
The Dodgers lost the NLCS to the Brewers. The position returned nearly 2x, helping cover the playoff business that *never* came.
A Columbia law professor told Fortune it works like “a form of bespoke insurance.”

We know that prediction markets are well calibrated. What is less well understood is who calibrates them.
We ran the first and largest study of its kind on a federally-regulated derivatives exchange, analysing over 1 billion trades on Kalshi to try to answer this question 🧵
We analyzed over 1 billion trades to find out why Kalshi markets are so accurate. A group of 15,000 superforecasters is largely responsible.
What stands out:
-There are 14,694 people on Kalshi who have significantly better predictive ability than other traders. This is measured by Brier skill score, which tracks trader calibration.
-They provide their forecasts to the whole platform, not just the top few markets. Skilled traders are active in 97.3% of markets.
-Timing and category change behavior: for example, superforecasters enter economic markets earlier, and sports markets later.
-These traders aren’t concentrated in the coasts or major cities. They come from all around the country, with Wyoming having the most per capita.
Prediction markets provide an incentive for smart people to do research, think rationally, and share their views with the world.
This incentive has brought almost 15,000 superforecasters to Kalshi, who create a public good by providing accurate forecasts to nearly every market on the platform.

“I can’t control what we’re charged for natural gas, but I can prepare for what happens if prices go up.”
That’s Nick Zoraian, third-generation owner of Family Laundry, which has served North Jersey for more than 50 years across six locations.
Every dryer and every hot water wash runs on natural gas. So Nick uses Kalshi’s natural gas markets to hedge. If prices rise past a set level, his trade pays out and helps cover the higher bills.
Energy prices, weather, interest rates. If it hits your bottom line, you can hedge it on Kalshi.

Replying to @MarshallCohen
This is an example of stupid polling. Asking people whether they personally support an activity is likely to get majority opposition to most activities since there are few activities most people partake in. For example, if you asked people "do you support getting an abortion," the answer would be 90% oppose. The relevant policy question would be do you favor legally banning it.
this is (almost) hilarious but also sad
How to make a poll say what you want:
Barely explain what prediction markets are.
“Do you like war?”
“Do you like betting on war?”
“These markets are gambling. Do you support gambling?”
“Prediction markets are horrible. Do you support prediction markets?”
Gather and publish the results.
Make sure to call it an unbiased poll.
