DraftKings fined $100,000 by New Jersey gambling regulators over inaccurate data

DraftKings sent inaccurate sports betting data to the state due to a coding error in their database, leading to overstated wager amounts on parlays. This required regulators to issue corrected financial data for several months, an event not seen in 13 years. DraftKings has since resolved the coding issue.
