Bets
Inspired by LongBets.Org, and Julian Simon's 1980 bet with Paul Ehrlich on the future price of five metals.

I find it useful -- when people have a strong disagreement in their predictions about future world events -- to quantify the confidence of their assertions by associating it with hard cash. If nothing else, it causes all parties to take stock of what they actually believed at the time, and then avoid various kinds of experimental bias by actually following through to see what the outcome turns out to be.
Open Bets
UFOs (6/19/2023). Within 5 years (expires 6/19/2028) and 12 years (expires 6/19/2035), there will be public scientific consensus for at least one specific concrete artifact, technology, or humanoid visitor of non-human origin. Don Geddis says NO; Win Ark says YES. Stakes: 5 years 20:1 odds $500:$20; 12 years even odds $500.
Fusion power (3/26/2018). Within 20 years (by 2038), a power generation plant will be constructed that generates at least 100MW of net energy via nuclear fusion. Don Geddis says NO; Win Ark says YES. Stakes: Steakhouse or Brazilian Churrascaria dinner.
Go (12/23/2003). Lifetime, biannual, man-vs-machine bet on the game of Go.
