I’d heard about the Long Bets foundation, but I had never visited the web site until today. It’s a lot of fun. Some famous people have made predictions about the future, such as "At least one person alive in 2000 will still be alive in 2150." (Peter Schwartz) and someone enjoys going on record against them.

Betting is purely ‘on the record’ because the money on both sides is automatically donated to the foundation: All Long Bets stakes are invested in a special-purpose Endowment portfolio called the Farsight Fund run by Capital Research and Management Company, based in Los Angeles, California.
