Marketplace Audience Graph • Social Signal

Marketplace's top 10 nearest neighbors span journalists, fellow podcasts, data-driven websites, and blogs — with no single entity pulling far ahead of the rest. Similarity here measures how closely two entities' audiences resemble each other in composition; the scores across the top 10 run from 0.98 down to 0.97, a band narrow enough that the shape is genuinely flat.

The two closest neighbors are journalists: Nina Totenberg (0.98) and Tamara Keith (0.98), both NPR correspondents by subcategory. Right behind them sit FiveThirtyEight (0.98) and NPR's Planet Money (0.98), followed by Fresh Air (0.98) and Pod Save America (0.97). Rounding out the top 10 are Merriam-Webster (0.97), Ari Shapiro (0.97), SCOTUSblog (0.97), and 538 Politics (0.97).

Tallying subcategories across the 10: four are Journalists, three are Podcasts and Radio (the same subcategory as Marketplace itself), two are Websites, and one is a Blog. The cross-kind presence is notable — journalists as individuals draw audiences shaped nearly identically to Marketplace's, sitting alongside fellow podcasts and data-focused web properties. No TV shows, no entertainment brands, and no activism organizations appear in the top 10.

The flat shape and compressed score range indicate that Marketplace's audience is not uniquely claimed by any single neighbor type — it sits at the intersection of public-radio listeners, data-literate news readers, and NPR-adjacent journalist followers.
