“It’s a wild market right now. I think what we’re doing has been very consistent since day one,” Robins said on CNBC in February. “I think the model’s working, and we’ll play the long game here.”

DraftKings’s trading price has plummeted in recent months, exacerbating a downturn that has now lasted more than a year.  DraftKings stock was trading at $17.82 on Wednesday, near its recent 52-week low of $16.56. The stock is down over 43% over the past three months, and down 72.1% over the last 12 months.

In February, DraftKings disclosed that Robins’s total compensation in 2021 was $14.03 million, down from $236.83 million in 2020.

Robins suggested that the tax revenue that California would receive from legalizing sports betting would directly benefit ‘homelessness and mental health’ in the state. Thirty U.S. states and Washington, D.C. now offer some form of legalized sports wagering, according to the latest tally from the American Gaming Association.
