Indy 500 Longshots: Best Sleeper Bets to Make

- The Indianapolis 500 takes place this Sunday at Indianapolis Motor Speedway in Indianapolis, Indiana
- How much value is further and further down the racing board on Sunday?
- Below, see my Indy 500 expert longshots and some even longer bets to make.
The Indianapolis Motor Speedway hosts the 109th edition of the Indianapolis 500 this Sunday, May 25th. The green flag drops around 12:45 pm ET, with television coverage on FOX. Remember, supplementary coverage is available on Sirius, NBC Sports, and Peacock. Could the 2025 edition be another case where several unexpected things happen all at once?
The speedway tests every bit of resolve and patience. One wrong move means the end of the day, and typically, the phrase “the wrong place at the wrong time” happens an awful lot. It is a 200-lap event that feels like a series of soap operas.
Now, we list the Indy 500 longshot odds. Yes, readers will notice we went a little down the board, then a whole lot down the board.
Indy 500 Longshot Betting Odds
Marcus Ericsson remains at +2000 but did not make our cut (4% chance or less of winning). At +2500 odds, the implied probability for Conor Daly, Colton Herta, Will Power, or Santino Ferrucci to win the race is 3.85%. After that, the percentages only get lower and lower. For those wondering, Helio Castroneves has a 3.23% of drinking the milk once more.

Odds as of May 24 (pre-race) at DraftKings Sportsbook. Check out the top US betting sites for wagering on the race for the milk.
Indy 500 Longshots To Bet
The weather expects to be dry but cloudy on Sunday with temperatures in the 60’s. When a rookie hits the gas and snags the pole, there went one of the better longshots on the board. Robert Shwartzmann rocketed up the odds and now sits at +1100 on DraftKings. Okay, I needed some Plan B’s and maybe a C or a D.
This Spring race will not have concerns of hot weather and hotter tires.
The track should be faster. Cooler temperatures mean more grip and consistency. This also means fewer mistakes. Conor Daly is the best qualified of our longshots in 11th. He did have a podium last year in seven races. Juncos Hollinger Racing has given him a pretty quick racing car. Daly could go a long way here if there is a little bit of attrition. The last winner from outside the Top 10 was Helio Castroneves in 2021. He qualified 21st.
Bettors do ask about Castroneves at +3000. The numbers have trended down since his fourth and last win in 2021. The driver has gone down to 7th, then 15th, then 20th last year. Castroneves qualified 22nd for this year’s race. Sure, he could get into the Top 10, but does his car have the grip and luck to stay with the top teams over 200 laps?
Admittedly, there may be better drivers than Daly, like Colton Herta. However, Herta qualified down in 25th and drivers rarely win that far down. The same goes for someone like Graham Rahal (26th). Again, Herta has a Top 10 in 2023, and a Top 5 may be the better avenue to go (+330).
- Indy 500 Longshot Prediction to Win: Conor Daly (+2500 at DraftKings).
Indy 500 Sleeper Bet To Make
Thanks again to Joey Mulinaro for his specials. If one wants to go a little crazier, there is always the Trifecta Box. I still do not believe Pato O’Ward will get passed again on Lap 200 this go-around. An O’Ward-Palou with Takuma Sato 1-2-3 rolls in at a whopping +5000. Given how last year ended up, this year could be a little calmer.
