Warren Buffett, in his first sit-down since stepping down as Berkshire CEO, gave the cleanest indictment of legalized gambling in a decade. He called it a tax cut for the wealthy. The math proves him exactly right. Americans wagered $165 billion at legal sportsbooks in 2025. They lost $16 billion of that. FanDuel pulled $6 billion of the losses. DraftKings pulled $5.3 billion. Every state with legal mobile sports betting collected a tax on the bettor side. New York alone took in over $1.2 billion in 2025 sports betting tax revenue. Layer the lottery on top. State lotteries generate over $90 billion a year. The bottom half of income earners account for roughly 70% of total spend. The average lottery player makes $38,000. A household earning $20,000 spends three times more on tickets than one earning $30,000. The implicit tax rate, meaning whatever the state keeps after prizes, runs 30 to 50% depending on the game. No other revenue source in America has that base and that rate. The structural design is the engine. A single straight sports bet carries a hold of 4 to 5%. A four-leg parlay carries a hold above 30%. FanDuel and DraftKings spent five years rebuilding their apps to make parlays the default product. FanDuel's blended hold rate hit 11.4% in 2025, up from roughly 7% in 2022. The product got worse for the customer and the customer wagered more anyway. Now look at the substitution. Nine US states have no state income tax. Seven of those nine run state lotteries. Seven of those nine have legalized sports betting. The states most committed to never taxing wealth are the same states running the largest extraction machines on people who cannot afford to lose. Read it as policy. Here is what Buffett is actually pointing at. The state needs revenue. It can raise income tax on the top decile, or it can run a lottery plus a sports betting tax. The second option raises the money from the people who can least afford it. The first option becomes politically optional. New York's $1.2 billion in 2025 sports betting tax is $1.2 billion the state did not have to ask of someone earning $5 million. DraftKings and FanDuel sell a privatized collection mechanism for a regressive tax that the state never has to defend at the ballot box again. Voters approve legalization once. Collection runs forever. The state takes a cut. The wealthy get a quieter top bracket. The bettor's cut shrinks every quarter as the parlay menu gets pushed harder. The function of a government, Buffett said, is not to play its people for suckers. Thirty-nine state governments now do.
@MikeIsaac I'd read an article about why this hasn't been a regulatory priority. My phone is essentially bricked.

@parkerconrad Saw this happen with a client who owned a huge chunk of SMB online invoicing market, until Xero came along, raised $100m+, and went on to not only eat their lunch but build a new market with their sales team. No coming back from that despite the massive head start.
