This is like the former CEO of Marlboro going on a multi day rant about the evils of vaping. This guy was is the fun version of Gouker. Hope he sticks around.

@danielalready_ It has already been shown that customers lose much faster on Kalshi than sportsbooks. Predictably Kalshi PR Legal machine spazzed and called it extortion before then quietly shutting the fuck up cause it’s true. casino.org/news/kalshi-di…

I don’t really dabble in sports “trading”, but I had this idea: Sports books have the chance to spoof tf out of prediction market exchanges. It’s somewhat well known that one can just regress over prices of books with weights scaling with historical brier’s of the books. Suppose pinnacle and another exchange or two “open” up the line 4-5% from their fair (cooperation would be needed), this probably isn’t enough for the average degenerate sports gambler to notice some crazy mispricing, but would be enough to meaningfully shift the lines on kalshi and poly. These books could then size up massively on these exchanges that don’t block institutions from trading and they’d be able to make some pretty big +EV coin flips. Now of course it goes without saying that they can’t do this every time or else people will rely on their pricing less; there’s some GTO mixed strategy here. Someone who knows the space better please correct me if it is obvious this would not work (ignore legal/moral reasons of course).

@goldenpants013 @Sports__Proj got another one. In the big 2026, how much of an originator's edge comes from factoring in data no one else has vs. out analyzing the data that everyone has? (Respective of the liquidity of the market you're trying to originate)

if you're a booking parlays, how do you go about managing the risk? It's not as easy as making your max liability per parlay quarter kelly and calling it a day. You could have a ton of 2 to 20 leg parlays that all share 1 or more legs. Maybe some of those legs shared with it already hit. Maybe you have some parlays that contain the opposing side of that leg that net out. Maybe the common leg is a huge favorite so if that wins it wont really tank the value of the rest of the legs that bad.

For those keeping score of sports betting numbers... lot of headlines these days about 'cannibilization' due to prediction markets. And while it is certainly a factor contributing to y/y decrease in recent months, I wouldn't be quick to dismiss other factors such as promo levels coming down y/y (look at the data), the sheep continually getting slaughtered with SGPs, general malaise in the consumer due to inflation and job market... lot of moving parts to consider is the point... ☕️

#Raiders HC Klint Kubiak prefers a rookie QB like Fernando Mendoza to see a veteran 'run the show' at first "Ideally you don't want him to start from Day 1. You'd love for him to learn behind somebody. That's a perfect world. It doesn't always work out that way. Sometimes they have to play from Day 1 and it's our job as a coach to get them ready to go. I think it does help the player, though, if they can sit behind a mature adult and watch how they run the show." Aidan O'Connell, 27, is the only QB on Las Vegas' current roster and the team is reportedly in the mix for Kirk Cousins, who's 37.

Inside the mind of an ex-SIG quant trader who can't turn off the EV brain - even for his kid's school choice Andrew Courtney (@andrewcourt1) ran the International ETFs Trading Desk at Susquehanna International Group for ~15 years before leaving in 2023. He now runs Kalshionomics (@Kalshinomics), a prediction markets analytics tool, and writes the Whirligig Bear, one of the sharpest prediction markets Substacks out there. "I think of everything as a bet. I kind of don't understand how you talk to normal people — they do not do that." SIG trains their junior traders with poker, spending 2hrs/day turning over cards after every hand, justifying every decision quantitatively AND qualitatively. 15 years later, Andrew views prediction markets the same way: read who's on the other side, size accordingly, fold when the whale comes back at you 10x. We cover: - Why SIG pays junior traders to play poker for 2hrs/day — & what happens after every single hand - The "one eye on the market, always" attention tax that destroys most people's careers - How to find edge in prediction markets by asking: who am I actually trading against? - Why meme-heavy, overhyped markets (Taylor Swift at the Super Bowl) might be the juiciest trades - The insider trading debate in prediction markets — & why it's "socially corrosive" - Floor trading vs. upstairs quant: why the transition saved his career - 40 connections after ~15 years at one of the world's best firms — the hidden cost of prop trading - Why he doesn't have collision insurance on his car (& the EV math behind it) Thank you so much @andrewcourt1 for coming on the pod!
