Nearly 600 Marketplace fans gathered at the Aratani Theatre in downtown Los Angeles to watch Kai Ryssdal present Marketplace Live, in partnership with LAist.

Kai was joined onstage by economics author, educator, and content creator Kyla Scanlon to talk about AI, prediction markets, Federal Reserve independence, and the war in Iran. Later, former “Marketplace Morning Report” host David Brancaccio joined Kai to discuss his experience rebuilding after the LA fire and his new job as Marketplace senior correspondent covering future effects.

Note: This show was recorded on March 29, and the situation in Iran has changed since then. Follow our latest coverage here.

A lot of sci-fi is dystopian. Solarpunk flips that on its head. The subgenre imagines a brighter future where humans have fostered a better relationship with technology, the environment, and each other, in spite of climate disaster. On today’s show, writer and academic Phoebe Wagner joins Kimberly to make us smart about solarpunk, its connection to the green energy transition, and why you should check it out if you want to shake off climate doom.

Here’s everything we talked about today:

• "Solarpunk: A Container for More Fertile Futures" from Solarpunk Magazine
• "Tired of Dystopian Sci-Fi? You Might Like Solarpunk." from Mother Jones
• "Sunshine and Seedlings" from Hydroponic Trash
• "Underground" from Tractor Beam
• Chobani ad on YouTube

We love hearing from you. Leave us a voicemail at 508-U-B-SMART or email makemesmart@marketplace.org.

A series of suspiciously well-timed Iran war bets placed on Polymarket have revived concerns about insider trading on prediction markets. But enforcement is something of a gray area. Marketplace’s Meghan McCarty Carino joins Kimberly to explain the relatively recent history of insider trading laws at the CFTC and what it could mean for prediction market platforms. Plus, the debate over whether insider trading on these markets is actually a good thing.
