Marketplace All-in-One

David Brancaccio has hosted an estimated 16,925 morning shows over 13 years. Now, for his final time in the host chair, David shares snippets of discussions he's had throughout the years, including with experienced local Del Rio, Texas-based reporter Karen Gleason, Nobel laureate Paul Krugman, and actor and entrepreneur William Shatner. Also on the program, Princeton's Burton Malkiel addresses concerns and gives advice about a potential AI bubble.

For his second-to-last time hosting an episode of "Marketplace Morning Report," David Brancaccio spoke with the author of arguably the most influential book on personal finance and investing of all time. First published in 1973, "A Random Walk Down Wall Street" argues that it’s super hard to beat the stock market. Its author, Burton Malkiel, is a Princeton professor emeritus and still going strong at 93. We have that conversation, as well as a preview of March's consumer price index.

This week, a Wisconsin city votes to restrict future data center development. Plus, the astronauts on Artemis II take their journey to social media. But first, Anthropic announced this week it has a new AI model called Claude Mythos Preview.

Marketplace’s Stephanie Hughes spoke with Joanna Stern, founder of the media company New Things, to discuss all these topics and more.

The personal consumption expenditures report, which is the Fed’s preferred measure of inflation, showed costs rose 2.8% year-over-year in Feburary. That’s above the target, but never fear: Resilient consumers keep on spending, despite rising prices. What’ll it take to shake things up? Also in this episode: A war-driven plastic shortage costs U.S. manufacturers, we give that GDP revision some context, and Kai visits a nuclear reactor.

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.
