In short: Copied IBKR's phantom-money prediction market, got a CFTC license first ("I said what a stupid thing it is I didn't think about doing that"), and refused his takeover offer. Mostly sports volume — "a huge amount of money" — but the states are up in arms and the Supreme Court decides next spring whether those contracts are swaps or state-licensed bets.
Kalshi is a private, federally regulated exchange where people trade yes/no contracts on future events. Peterffy says it copied his earlier play-money version, got licensed first, and turned down his offer to buy it. Most of its money comes from sports bets, which states are fighting in court; the Supreme Court is expected to decide next spring whether those are federally regulated financial contracts or gambling that needs state licenses — a big risk to its business model.
18:22So we actually came out with it, but we came out with it with phantom money. So it wasn't real, but it was real enough for the guys at Kalshi and Polymarket to see it. And they said, "That's a great idea," and they came out with it for real money and so that's what happened, and so now they are way ahead of us of course. — And when Kalshi came out you tried to buy them. — That's right, because they went to the CFTC and they got licensed and I said what a stupid thing
In short: The host shows Kalshi's "which companies will sign a Venezuelan oil agreement" market; Sankey flags the contract definition ("you have to kind of read the small print") and then gives his long Shell / short Exxon read. A venue reference.
21:19the Houthis. — Trump also promised that Venezuelan oil is going to bring down the price of gasoline. This is from Kalshi. It's a prediction market. Which companies will sign a Venezuelan oil agreement? It looks like Shell is in the lead 62%. whether or not a Shell or Exxon, I'll let you comment on that, but the bottom line is whether or not Venezuelan oil production will kick in early enough to make a difference.
In short: The show's sponsor, and also the data source the host puts to him: the market on which lab lists first prices Anthropic at 93%. Eisman engages with the implication — that the S-1 he is waiting on is most likely Anthropic's — rather than with the platform.
6:16This is Will Open AI or Anthropic IPO first? 93% Anthropic. Open AI. In your show, The Real Investment Playbook, you talked about how once these companies do go public, we'll have real data to base a lot of our decisions on. What are some of the real data that you're anticipating? What are you looking forward to? — Well, what I'm really looking forward to is I'm pretty sure that Anthropic's revenue story will be good through June.
In short: Named with Polymarket as the second venue in the same critique — "or on Polymarket or Kalshi… We've created a gamblers mentality. Not an investing mentality." His objection is behavioural: it skews the return expectations people bring to actual investing, so that a compounding 20%-a-year record looks unimpressive next to a lucky 500% ticket.
18:22We've created a gamblers mentality. Not an investing mentality. A gambling mentality. I try to be generous and call it speculation. But yet these people think they're investing. And so their expectations are skewed. The history that they're relating to is skewed and this is part of the problem. So I'm a little bit long-winded.
In short: The "what's cool now" answer. "Over the last year or so… prediction markets have taken off. I can't prove it, but I think young investors have moved to prediction markets. Bitcoin is no longer the cool toy. Kalshi is." Framed as the cohort shift, not a valuation call.
Kalshi is a regulated prediction market — a venue where you buy and sell contracts on whether real-world events will happen, so the price acts like an odds quote. Eisman brings it up not as an investment but as an explanation for a shift in behaviour.
His claim is about where speculative attention has gone: young traders who once treated Bitcoin as their primary asset class have moved to prediction markets. "Bitcoin is no longer the cool toy. Kalshi is." He concedes he can't prove it — but he uses it to explain two data points at once: Bitcoin's decline and the pressure on betting platforms like DraftKings and crypto-heavy brokers like eToro.
25:01Year-to- date, Bitcoin is down 27%. Over the past 12 months, it has declined 46%. Also, I think something else is going on here. Bitcoin used to be cool. Young people traded it as their primary asset class. Over the last year or so, however, prediction markets have taken off. I can't prove it, but I think young investors have moved to prediction markets.
In short: Eisman's "little pet thesis" for why Bitcoin has been weak: "all the young people who used to trade Bitcoin are on Kalshi… they just don't care anymore. And so it's just not hot. So my guest said something like Bitcoin is for boomers." Prediction markets as the competing outlet for speculative risk appetite.
40:04So each of the big banks might have their own token or their own digitized tokenized deposits, tokenized money markets. And how the banks compete with stable coin is an interesting thing. It comes so So before we get to stablecoin, just a little pet thesis about Bitcoin, which I explored with a guest many months ago, which is that the reason why Bitcoin's been so weak is that all the young people who used to trade Bitcoin are on Cal Shi.
In short: The prediction-market firm behind the "stunning" MIAX decline narrative. Its May 29 CFTC approval to list a U.S. bitcoin perpetual triggered CME's suit; it offers almost 6x leverage — "put down $200 to control $1,000 of bitcoin… heads you're up 50%, tails you lose it all." Horizon Kinetics' conclusion is that nothing precludes the incumbents from offering the same event contracts, so Kalshi and Polymarket "aren't a threat to incumbent exchanges so much as an indicator of extraordinary next-generation, next-decade expansion possibilities."
Kalshi is a private prediction market — you buy yes-or-no contracts on sports, economic data and political events — and it is the company clients blamed for the exchange stocks falling. In May, U.S. regulators let it list a bitcoin "perpetual," which prompted CME to sue the regulator.
Horizon Kinetics' read is deliberately unexcited. Nothing stops the big regulated exchanges from listing the same event contracts, and several already are. What Kalshi and its peers really demonstrate is that there is demand for a much wider universe of tradable things — which is an opportunity for exchanges, not a threat to them. The firm is blunt about the product itself: Kalshi advertises roughly 6x leverage on bitcoin, where $200 controls $1,000, a 10% move makes you 50%, and a 20% move against you takes everything. That is a wager, not a hedge.

In short: Context only: the SEC rules "allowing for these perpetual futures I think for Kalshi and Polymarket" are what people interpreted as a threat to the exchanges' moats and drove the sell-off — the exogenous drop that let him buy CBOE. Nothing about the exchanges' business actually changed. Also flagged as part of the prediction-market/gambling wave.
3:49For example, in the last couple weeks, you've seen a major correction in a lot of the exchanges here in the US, CBOE, CME, ICE, the big ones here in the US. What precipitated that? Well, they were very highly valued because we've had a bull market and so CBOE and some of these other things really got ahead of themselves, and then some rules were passed by the SEC allowing for these perpetual futures I think for Kalshi and Polymarket that people interpreted as a threat to the moats for these exchanges. However on further analysis it doesn't appear that that's really the case, which we don't have time to get into.
In short: Context only: the "recent legislation that opened up these perpetual futures for Kalshi" is what knocked the listed exchanges "down massively" — the exogenous drop that let him buy a quality exchange (his jul-09 CBOE buy). Nothing about the exchanges' business or moat changed.
28:55know, I like the exchanges but, as you know, because of this bull market a lot of them became pricey recently over the last year or so. And so I kept looking at them, looked at them. Okay, bang, had this recent legislation that opened up these perpetual futures for Kalshi and that, and these things dropped massively. Okay.
In short: Lumped in with Polymarket — "I don't like either of these companies." Both pay creators "obscene amounts of money" to sponsor videos; same gambling/addiction objection.
29:24And I'll lump in Kalshi. I don't like either of these companies. Prediction markets I think is a fancy way of saying gambling. What these companies do is entice you with the enticement of gambling. In reality, what these companies sell is a highly addictive product. Gambling can wrap people into it. It can change their life, and it puts them in a lower economic state.
In short: An addiction business model: exploits near-miss psychology (a near-miss reads as an "almost win" and drives more betting); kids reportedly access it via parents' accounts / VPNs. "Everything I said about Kalshi applies to its customers as well."
Kalshi is a prediction/betting marketplace. Eisman believes it runs on an "addiction model": it exploits "near-miss" psychology — when a gambler almost wins, the brain treats it as an "almost win" and is driven to bet again, more often, rather than walk away.
He adds two alarms: kids reportedly get in using parents' accounts or by faking their age behind VPNs — and the addiction critique applies just as much to its grown-up customers. It's a profit model he distrusts on both ethical and durability grounds.
15:43We discuss the legal theories behind these cases and which cases he thinks have real potential. For our audio and video listeners, see the premium link at the top of the description. If addiction were confined to just social media, that would be bad enough, but it has spread. For example, Kalshi is a company that I believe uses an addiction model to increase the level of customer betting.
