Polymarket is offering a $50 trading bonus through referral code HANDLE for new users who make a $20 deposit on Sunday, May 24, 2026, giving Indy 500 fans a way to get into the market before the green flag waves at 12:45 p.m. ET.
The promotion can be used on Indy 500 prediction contracts ahead of the race and while the race is underway. Users can trade on the winner, the top three finishers, the top five finishers, head-to-head matchups and other markets tied to the 500-mile event.
SportsHandle says the deal is simple: “Redeem a $50 trading bonus thanks to Polymarket referral code HANDLE and a $20 deposit.” The outlet also frames the offer as a way to “celebrate Indy 500 day with a $50 trading bonus,” pointing bettors toward a race-day market that moves as quickly as the field at Indianapolis Motor Speedway.
The timing matters because the offer is built around the same day the race starts, with the bonus available for pre-race positions and live-race bets after the opening lap. For fans looking for a market angle on the biggest single-day event in American motorsports, the promotion is designed to meet them at the exact point the race begins to matter most.
Access is limited. The referral code is available in AK, AR, CA, CO, CT, DE, FL, GA, HI, ID, IN, IA, KS, KY, LA, ME, MN, MS, MO, NE, NH, NM, NJ, NY, NC, ND, OK, OR, PA, RI, SC, SD, TN, TX, UT, VT, VA, WA, WV, WI, WY and Washington, D.C. Sign-up is not available in AZ, IL, MA, MD, MI, MT, NV and OH, and users must be at least 18 years old with a legal U.S. residential address in the applicable state, D.C. or U.S. territories.
That leaves a narrower pool than the race’s national audience, but it still covers much of the country. For those eligible, the pitch is straightforward: deposit $20, collect the $50 bonus and use it on a market where the price can shift with every turn, caution and pit stop.
Malukas is the writer’s Indy 500 winner prediction at +250, a sign that the race card is open enough for bold opinions before the start. Whether the bonus lands on the outright winner or a head-to-head play, the real hook today is that the market is open when the race is still unsettled and the green flag has not yet fallen.
