    The media will all rush to a narrative of "legalizing sports betting led to this behavior" The truth is "this behavior" has long existed, and legalizing sports betting created a world where cheaters could be found and punished

    All of Massachusetts sports betting operators refusing to participate in today’s roundtable on the limiting of players is probably the biggest middle finger I’ve seen by licensees in the 20+ years I’ve been in this industry

    Been thinking how like “taxing unrealized capital gains” this proposed Federal gambling tax change is, where someone may receive a tax bill when no actual profit has been made. Doesn’t taxing folks for money they didn’t make seem so obviously wrong?

    I’m not a Democrat or a Republican. I’m an @Eagles fan. Philly does more to honor our military than any town, since I was a kid.

    Nothing to see here…just the CEO of the largest US-based sports betting company admitting his multibillion-dollar firm can’t do what some offshore sportsbooks have done for >25 years (*btw, “they don’t pay taxes” has zero to do w/ their risk mngt expertise)

    DraftKings CEO Jason Robins spoke at a BofA event Thursday, and was asked about prediction markets. Here's a snippet, in which JR explains why he thinks it's harder for a prediction market to offer what an online sportsbook can. A DK can limit sharps, but a PM can't, he suggests.
