The 50th International 500-Mile Sweepstakes was held at the Indianapolis Motor Speedway on Monday, May 30, 1966.

Eleven of the 33 starters, a whole third of the field, was eliminated in a first-lap accident right after receiving the green flag on the mainstretch. No drivers are injured, except for A. J. Foyt, who hurts his hand scaling the catch fence trying to escape the wreck scene. Only seven cars, the fewest finishers ever, are still running by the end of the race.

First-time starter Jackie Stewart leads by over a lap when his oil pressure drops too low on lap 190. He parks the car and walks back to the pits. Fellow "rookie" Graham Hill leads a total of 10 laps to win, the first rookie winner since 1927.

Defending race winner Jimmy Clark spun twice during the race, and finished second.

Time trials

Time trials was scheduled for four days.

• Saturday May 14 - Pole Day time trials
  • Mario Andretti won the pole position with a four-lap track record of 165.889 mph. His best single lap was a record 166.328 mph.
  • Chuck Rodee was killed in crash. On his second warmup lap in turn one, Rodee backed in to the outside wall, and he died of his injuries at the hospital.
  • A total of 18 cars completed qualifying runs on a chilly pole day.
• Sunday May 15 - Second day time trials
  • After crashing on pole day, A. J. Foyt qualified at 161.355 mph, the fourth-fastest car in the field.
• Saturday May 21 - Third day time trials
  • Unser brothers Bobby and Al qualified, with rookie Al (162.272 mph) leading the speeds for the day.
  • Bobby Grim qualified his turbo Offy front-engined roadster at 158.367 mph, the only such car in the field.
• Sunday May 22 - Fourth day time trials
  • Two drivers managed to bump their way into the field, Ronnie Duman and Larry Dickson.
  • Greg Weld wrecked two cars (one of which was a popular Granatelli-Novi), but was uninjured.
  • Bobby Grim, the slowest qualifier, holds on to the make the field in his front-engined roadster.

Controversy

After the race, some confusion in the scoring led to a controversy, wherein second place Jim Clark's team thought they were the rightful winner. Clark had spun on two separate occasions during the race, but did not make serious contact during either incident. He did not stall his engine either time, and was able to drive to the pits for the crew to inspect the cars quickly both times. Clark's team contended that he did not lose a significant amount of time, and figured that they were still one lap ahead of Hill at the finish. The scoring pylon, which was manually controlled and unofficial, changed somewhat frequently as the scoring was ironed out, to the dismay of many Clark's crew in particular. The unofficial results at the conclusion of the race showed Graham Hill winning by 41.13 seconds over Clark.

The morning after the race, USAC released the official results, and the standings were unchanged. Colin Chapman and Andy Granatelli, the entrants of Clark's Lotus team, declined to file an official protest. A possible explanation given was that the Lotus crew did not see Hill pass by Clark during the aftermath of the second spin.

Race winner Graham Hill admitted to being "puzzled" and "surprised" to be the winner, while other unsatisfied competitors chimed that he "never passed a car all day long." The IMS Radio Network, which scored the race independently from the USAC officials, also came up with Hill as the first place car. The apparent controversy died out quickly, and no official action was ever taken. Years later the subject is still mildly debated in racing circles.

A theory emerged that scorers accidentally omitted one lap from Jim Clark's official total. Therefore, he was effectively placed behind Hill at the finish. The car of Al Unser, Sr. was painted nearly identical to Clark's. The theory is that when Al Unser crashed out of the race on lap 161, scorers mistakenly thought it was Clark, and as Clark drove by, they credited that lap to Unser by mistake.
