I think this is kind of what happened with Kalshi in the election, it was a bit of a Chad GPT moment for our industry. An industry truly becomes an industry when there's a rivalry. Without Polymarket, we wouldn't have pushed our marketing and pushed our product as hard.

Did you ever cross paths with SBF? And what did you learn from observing FTX's implosion? This is 20VC with me, Harry Stebbings, and Kalshi is one of the fastest growing companies on the planet right now. In the last week, they announced their $1 billion raise and an $11 billion valuation. They announced partnerships with CNN and CNBC, and today, their founder Tarek joins me for his only interview following these announcements to give me the exclusive lowdown.

**Tarek Mansour** (4:17)
Thanks for having me. Super excited.

**Harry Stebbings** (4:19)
Dude, I got to start on the main thing, a billion dollars. The first thing I have to ask, why does Kalshi need a billion dollars?

**Tarek Mansour** (4:26)
That's a good question. What we've realized in the last, I would say, six to nine months, given the sort of acceleration of what we've seen, is the opportunity ahead of us is maybe even bigger than we had all possibly imagined. There's a few symptoms of that. So one, Kalshi this year is at this scale, at least, I think the fastest growing company in America outside of AI. I think Anthropic is going faster, and I'm not sure about Mercure and Corsair, but we're growing at that sort of, at that pace, at that rate. And number two, what we're seeing, which is even more important, the qualitative thing that we're seeing is there's a real and rare shift in consumer behavior. People are kind of turning from like passive watchers of events or news or sports or other things that they engage with in real life to active participants. That natural behavior of wanting to predict the future or debating about something is turning into activity on Kalshi. That is rare. Like when you see this shift in consumer behavior, I mean, you've seen it in Airbnb with the hosts and Uber with riders, when you're seeing a new class of people, in this case, prediction market traders becoming a thing, that's indicative of a very, very massive opportunity ahead of us. And, you know, when you have a massive opportunity ahead of you, you want to go big, you want to bet big. And so we're really scaling up for that opportunity here.
