In July 2010, US Senator Blanche Lincoln (D-Ark.) predicted the rise of prediction markets and the problems they could cause. If not properly regulated, Lincoln warned during Senate proceedings on the Dodd–Frank Wall Street Reform and Consumer Protection Act, prediction markets could evade gambling laws by offering "event contracts" that let people place wagers on sports games.
"It would be quite easy to construct an event contract around sporting events such as the Super Bowl, the Kentucky Derby, and Masters golf tournament," Lincoln, who played a key role in making the law that now regulates prediction markets, told fellow senators. "These types of contracts would not serve any real commercial purpose.
Today, Lincoln is a lobbyist for prediction market Kalshi and has urged the Commodity Futures Trading Commission (CFTC) to allow sports gambling on the markets. The firm she founded has received $480,000 from Kalshi since 2024 in exchange for lobbying Congress and the CFTC for looser regulation of event contracts.
