There’s a 16% EV Dabble play on Selene right now We’ve been posting a lot about prediction markets, market makers, and sportsbooks But don’t forget that Selene also has a DFS optimizer complete with its own auto slip builder The auto builder will automatically build the best profitable slips for you with just the click of a button It account for the optimal number of legs, whether the play should be insured or not, and tells you the EV and exact bet sizing In case the Dabble slip bumps, I’ve included an 8% EV variation as well

Right now, a Kalshi market maker is trying to get down MILLIONS of dollars on NFL middles But you can get the same middles on DraftKings, Onyx Odds, or Courtside, for an even better price Not only that, both sides of the middle are +EV, and the cumulative EV of each middle could be 10% or more We’re seeing MULTIPLE of these A market maker on Kalshi is putting up millions of dollars currently as direct arbs to the odds DK has. Who do you trust more, an institutional Kalshi market maker or a billion dollar odds provider powering DK? The bets in question are spreads, and not only is each bet an arb to DK, the market maker is offering both sides of spread of multiple games. If you take both sides of the spread on DK that are arbs to Kalshi, you will have a middle, which is basically even more +EV X only let us include screenshots of a couple of these middles, but there are way more on Selene's Maker Radar Read on if you want to learn what the bets are and how the middles work- let’s get into it Throughout the day, Selene’s Maker Radar has flagged over 6 NFL games and counting where Kalshi’s odds are a direct arbitrage to what’s being offered on DK. Onyx Odds and Courtside use the same odds provider too, so Kalshi’s prices are arbs to them as well We’ll go over some examples, but first let’s describe some of what we’re seeing One of the most important parts of trading is knowing who your counterparty is, and what makes this example interesting is you can be 99% sure that the market maker disagreeing with DK on all of these markets is the same person. Why? Because each of the trades carries a couple very similar characteristics: 1. The arbs are on NFL spreads 2. On each trade, the market maker is trying to get down ~$260K 3. The price on Kalshi is the same for half of these trades, 8.5% That tells us the market maker is running the same model for each market, which is why its giving them the same sizing and pricing for the spread in different games In the first screenshot, we see that Kalshi is letting you wager up to $24,104 on the Falcons -13.5 spread at +1070 odds. That means the market maker is trying to get down $258K on the other side, Bengals +13.5 at -1070 odds. DraftKings is offering you -1020 on the Bengals +13.5 If you were to bet both sides, it’d be a 0.38% ROI arb with a guaranteed $4.46 profit for every $100 placed on Kalshi. But arbing between DK and Kalshi isn’t the play here, because the market maker is telling us that the spread on both teams is +EV, and we should take both for a middle A middle basically means you have two bets that guarantee at least one of those bets will win, while also giving you the possibility of having both bets win For example, the Falcons +9.5 and Bengals +13.5, both of which the market maker is trying to get down on and both on DraftKings at better odds. As long as the Falcons win by 13 points or less, or the Bengals win by 9 points or less, we would win both plays Let’s say each spread bet is 2% EV. If we take two spreads, thats 4% in EV. Now if both those spreads form a middle, that could be an additional 2-8% EV on top. These are 10% EV plays here These middle bets are occurring on the Browns vs Saints, Broncos vs Panthers, Texans vs Chargers, and thats just what we’ve caught while occasionally checking Selene throughout the day So when you do the math and expand it out, the market maker is trying to get filled for $260K on each spread market, multiple spreads per game, and multiple NFL games. That comes out to millions of dollars being deployed With that much liquidity behind them, the market maker has to be an HFT firm like SIG or one of the top syndicates

Update: it’s still going on today teapawt.org/seleneodds/status/2118…
FYI the Kalshi market maker is disagreeing with DraftKings on even more spreads today There’s still MILLIONS of dollars that the market maker is trying to get down and the spreads from yesterday are still available It looks like DraftKings odds provider is on an island, and they provide the odds for Onyx Odds and Courtside too Selene is showing entire ladders on Kalshi that are arbitrage trades to DraftKings, as well as the spreads for more games popping up like the Rams vs. Commanders, Texans vs. Chargers, and Cowboys vs. the Colts There’s literally double digits of these spreads available where Kalshi is disagreeing with DK to the order of $260K on each of them The signals for these are strong, so let’s talk about each of them: 1. When you look at it from a simple positive EV betting perspective, we can safely assume DK’s odds are off because they can be devigged to several sharp books besides Kalshi and still come out positive EV. When devigged to Pinnacle, Novig, Polymarket, even FanDuel, the results all come out +EV 2. The arbitrage percent to Kalshi is 1-2% for a lot of these plays. This means if you decide to take both sides, on Kalshi and DK, you would lock in a guaranteed 2% profit. Arguably this is the strongest signal that someone is off on their pricing, because arbitrage opportunities are literally free money, which is why they’re rare 3. The market is trending upwards in one direction, with all the sharp books following Kalshi meaning they agree with their prices, while DK, Onyx, and Courtside are the only books moving down in the opposite direction. Its basically their model against everyone else’s We’re also seeing more interesting stuff going on in these markets, like automatic refillers on Kalshi, but that’s a post for another time For now, we just know that DK’s odds provider is on an island by themselves and it’s been days since they’ve made a move towards the market For a major sport like NFL, it’s rare that a large odds maker won’t update their lines for so long and leave these kinds of arbs available Do they know something the market doesn’t?

The Pistons won’t sell me like the Lakers did right? …..right..??

I can’t believe this is what sold me out of $8,000 yesterday 😒
THIS IS WHAT NBA NEPOTISM LOOKS LIKE. With 2:28 remaining, the Lakers led Toronto 122-107. The game was effectively over. Enter Bronny James. His next 1 minute and 44 seconds: 0 points. 0 rebounds. 0 assists. 1 turnover. MINUS 11. Suddenly, a 15-point lead was down to FIVE. JJ Redick had to send Luka Dončić, Austin Reaves, and Walker Kessler BACK onto the floor to rescue a game they had already checked out of. Watch the video. The level of basketball being played here is absolutely embarrassing. An NBA roster spot is supposed to be earned through talent and performance. How much longer are we supposed to pretend Bronny James has demonstrated that he belongs on this floor? LeBron's greatness doesn't automatically transfer to his son. The longer this charade continues, the more embarrassing it becomes for the Lakers, the NBA, and LeBron's legacy. This is professional basketball. Start treating it that way.

This just in for STALE LINES New York Knicks, -122 Available on Courtside, and also DraftKings and Onyx at -125 Hit the moneyline on all three, and after you’re done, the Knicks -1.5 spread at -115 is also good Sorry LeBron, but we’re going to need the 76ers to lose tonight
Fun fact: did you know Onyx Odds and Courtside are both mirrors of DraftKings? That means their odds are the exact same as DraftKings So if you’re limited on DraftKings, you can go straight to Onyx or Courtside to get your bets in, and Onyx especially has high limits Save this tip for the next time you can’t get down enough on DraftKings

You’ve heard about DraftKings and Onyx, but did you know Bally Bet and BetRivers are also mirrors? Just like DK and Onyx, Bally Bet and BetRivers share the exact same odds for a lot of their plays We did a data pull on our backend and 93% of their odds are the same What’s the reason? Well they actually both share the same odds provider, Kambi In fact, most sportsbooks don’t build their own models and odds engines in-house. Instead, they outsource to a third party provider that feeds them lines and prices It’s the same reason why DraftKings, Onyx, and Courtside all have the same lines. Kambi is one such odds provider, and in this case they’re the ones Bally’s and BetRivers are using If you go to Kambi’s website, you might even find another major sportsbook using them also.. So if you’re limited on either Ballys or BetRivers, go check out the other the next time you need to get more money down
Fun fact: did you know Onyx Odds and Courtside are both mirrors of DraftKings? That means their odds are the exact same as DraftKings So if you’re limited on DraftKings, you can go straight to Onyx or Courtside to get your bets in, and Onyx especially has high limits Save this tip for the next time you can’t get down enough on DraftKings

Apparently he just cashed his 3rd 6-man pick this week On PrizePicks again He can’t keep getting away with this 😭
So one of our subscribers recently discovered that he can just spam Selene’s DFS auto slip builder and blind tail the plays lol These are his results after using it just on PrizePicks for a week
