LIVE LEADERBOARD: Here's the race running order

7:45 p.m.: Josef Newgarden wins 2024 Indy 500

Josef Newgarden wins his second consecutive Indy 500, outdueling Pato O'Ward over the final laps and earning a $440,000 bonus for repeating as champ of the rain-delayed race.

Just like last year, Newgarden exits his car at the Yard of Bricks and heads into the crowd to celebrate.

"I love this crowd," Newgarden tells NBC moments after the race. "I've always got to go in the crowd."

O'Ward, now twice a runner-up, takes the lead in Turn 1 on the final lap, but Newgarden passes back heading into Turn 3 and holds on by 0.341 seconds. O'Ward makes the most on-track passes (43).

"So (expletive) close," a frustrated O'Ward says. He also finished 2nd in 2022.

For repeating as champ, Newgarden earns the big bonus from Borg Warner. The last repeat winner was Helio Castroneves in 2001-02. Newgarden leads 26 laps.

Team Penske earns its record-extending 20th Indy 500 victory.

Kyle Larson, who had hoped to drive the Indy 500 and Coca-Cola 600 on the same day, stays in Indianapolis and finishes 18th. He gets a penalty for speeding on pit road, taking him out of contention. However, he leads 4 laps.

Before taking off for Charlotte to join the Cup race, which has already begun, Larson says he wants to return to Indy.

Pole-sitter Scott McLaughlin leads the most laps (66) and finishes 6th. Christian Rasmussen is the highest finishing rookie (12th).

Biggest movers: Conor Daly gains 19 positions from the start (from 29th to 10th), Dixon gains 18 (from 21st to 3rd), as does Graham Rahal (from 33rd to 15th). Will Power loses 22 spots (2nd to 24th).

Seven of the top 10 cars have Chevrolet power.

The race is delayed 4 hours by rain.
