Prediction markets are a hot topic again — even cartoon characters are talking about them (South Park). But beyond the buzz, what is a prediction market, exactly? How do they work, how are they designed, and what makes them work?

We answer all these questions and more in this deep-dive featuring experts Alex Tabarrok (professor of economics at George Mason University) and Scott Kominers (a16z crypto research partner and Harvard Business School professor), in conversation with Sonal Chokshi.

While we originally covered this topic during last year’s election, the discussion is more relevant than ever today, as we go into the claims people make about prediction markets — what they’re good for (and not); how they fit in with other trends like AI, futarchy, and the crisis in scientific publishing; and where blockchains and crypto come in.

This is your definitive explainer on the topic.

Are You A Charlotte?

Are You A Charlotte?

In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
