Details about these bets—what data they draw on, how quantities are calculated, how payouts will be handled, and so on—are available at the Long Bets website (longbets.org). This site is also where you can sign up for one or more bets if you’re interested, and confident enough that these predictions are wrong. Each bet can be between $50 and $1,000. I’m putting up $100,000 of my own money.
