Current IndyCar Freedom 250 winner markets

There are 33 drivers in the full market based on live data from Polymarket as of August 20. However, we discovered that because it’s a newly launched market with untraded contracts, the order books are empty. In other words, the current market prices are default numbers, not real market values, because no real traders have placed active buy or sell limit orders yet.

Once real trades are closed, everything will reset to normal, and the market prices will keep shifting as we get closer to the race. So feel free to check prediction market news for the latest updates.
