IndyCar Odds to Bet Online

Motorsport betting has grown exponentially in popularity, and IndyCar betting is a worldwide phenomenon that attracts millions of fans, many of whom want a vested interest in the races.

On Sunday, August 23, the IndyCar series will return with the Freedom 250 Grand Prix of Washington, DC:

After this event, here’s a snapshot of the remainder of the IndyCar season as follows:

  • August 29: Snap-on Makers and Fixers 250 (Milwaukee Mile, WI – Race 1)
  • August 30: Snap-on Milwaukee Mile 250 (Milwaukee Mile, WI – Race 2)
  • September 6: IndyCar Grand Prix of Monterey (WeatherTech Raceway Laguna Seca, CA – Season Finale)

IndyCar Season Heading Into the Home Stretch

Four races are currently left on the 2026 IndyCar season, and as of this moment, the standings show that Alex Palou, riding under the Chip Ganassi Racing Team’s banner, is in the pole position to claim their fourth consecutive IndyCar Driver’s Championship and his fifth overall.

The Spanish sensation is the reigning king of IndyCar, but there are several of his competitors who are eager to secure the throne. Below are the last four IndyCar events, replete with last year’s winner and a look at who may be poised to cross the finish line first in 2026.

Freedom 250 Grand Prix of Washington, DC – Sunday, August 23, 2026, at 1:00 PM ET

This is the race’s inaugural event, but it is no surprise that Alex Palou is the betting favorite at odds of +140 at the time of this writing. Palou has won three of the five street courses he has entered this season, with victories at St. Petersburg, Long Beach, and Detroit, while finishing second at Arlington behind Kyle Kirkwood and fourth at Markham on August 16th.

Grand Prix of Milwaukee Race 1 and 2 – August 29-30, 2026, at 2:30 PM ET (1) 1:00 PM ET (2)

The Grand Prix of Milwaukee is a doubleheader of IndyCar magic, each a stand-alone event on the paved asphalt of the Milwaukee Mile oval in West Allis, Wisconsin. Each race is 250 laps or over 253 miles, but last year the series scaled this event to just one race, won by Christian Rasmussen.

In 2024, Pato O’Ward won Race 1, followed by Team Penske’s winning driver, Scott McLaughlin, in Race 2 of that year. IndyCar odds at BetUS will be up for these two events as the dates draw closer.

Grand Prix of Monterey – Sunday, September 6, 2026, at 2:30 PM ET

It is safe to say that Alex Palou will once again be the bettor’s choice in this event, considering he has won it the last two consecutive years and notched his first Monterey victory in 2022, for a combined three championships at the WeatherTech Raceway Laguna Seca near Monterey, California.

BetUS Sportsbook is proud to offer IndyCar odds on every event, including the last four races of the season as well as IndyCar championship futures.

Race to Better Odds with IndyCar Betting

Every IndyCar race has its own story. One weekend it’s a fuel-saving masterclass; the next it’s a caution-filled sprint where strategy changes in an instant. That’s part of what makes the series so entertaining, and why IndyCar betting has grown increasingly popular.

Whether it’s head-to-head matchups, predicting podium finishers like the top three and top five, outright winners, or IndyCar championship futures, every IndyCar Series race is covered at BetUS, along with live betting on all events as the race unfolds.

Understanding IndyCar Odds

IndyCar odds are easily understood. All we need to know is whether there is a plus (+) or minus (-) in front of the number.

Positive odds (+) = the underdog. This number tells you how much profit you’d make on a $100 bet. For example, a driver with +600 odds to win a race means that a $100 bet will earn a profit of $600 for a total return of $700 ($600 profit + the original investment of $100).

Negative odds (-) = the favorite. This number tells you how much you need to wager to make $100 in profit. For example, a driver with -150 odds to win a race means that $150 must be bet to earn a profit of $100 for a total return of $250 ($100 profit + the original investment of $150).

Betting on an IndyCar race is more than just about the driver. Collaboration between the driver, the pit crew, and the spotter, who is the team’s eyes in the sky, is essential. Constant communication and fuel awareness during the race are critical, as one missed fuel stop can spell the end of the race for even the best drivers in the world.

It is also important to research how a driver has historically performed at the track on which they will be racing. Weather conditions can also change the nature of road and street courses, but rainy conditions are not allowed on oval tracks where speeds can soar to 240 mph or more.

Some of the top IndyCar drivers to watch are Alex Palou, David Malukas, Kyle Kirkwood, Christian Lundgaard, and Pato O’Ward, all of whom are at or near the top of the season IndyCar standings.

Naturally, Indy 500 odds are a popular market, but an IndyCar season does not consist of just one race.

What Makes the Indy 500 Special?

The Indy 500 is one of those events that’s been around for so long it’s embedded itself as a piece of national sports culture at this point. The race is held every year at the Indianapolis Motor Speedway, and even people who don’t follow racing are aware of its existence.

The grueling test of endurance features 500 miles of racing at blazing speeds, with these exotic open-wheel cars hitting speeds of more than 200 miles per hour on the straightaway and racing within inches of each other. The course is 2.5 miles, which means a total of 200 laps that normally last a little over three hours.

Ray Harroun was the inaugural Indy 500 winner back in 1911, whose average speed of nearly 75 mph was considered cutting-edge at the time. Over the years, the race has morphed into a complex amalgam of engineering design to reduce aerodynamic drag and maximize thrust, coupled with an elite pit crew to complement the car and the driver.

Between the pre-race singing of “Back Home Again in Indiana,” followed by the traditional glass of milk being gulped by the winner in Victory Lane, the Indy 500 is more than just a race; it has become a piece of Americana.
