Six of Jimmy Kimmel's ten nearest neighbors by audience similarity are comedians — Sarah Silverman (0.93), Kevin Nealon (0.92), Whitney Cummings (0.92), Conan O'Brien (0.91), Jeff Ross (0.90), and Judd Apatow (0.89) — making stand-up and comedy-adjacent figures the defining texture of this audience shape. Similarity here measures how closely two entities' audiences resemble each other in composition, not thematic overlap.

The remaining four neighbors span three other subcategories. Actors account for two slots: Jeremy Piven leads the entire top 10 at 0.94, and John Cusack sits at 0.91. Arnold Schwarzenegger, classified as a Politician, appears at 0.90 — the only politician in the top 10. Bill Maher (0.89) is the sole fellow TV Personality, meaning Kimmel's own subcategory is nearly absent from his nearest neighbors. The scores run from 0.94 down to 0.89, a narrow band consistent with the flat shape: no single neighbor dominates, and no sharp drop separates the top from the bottom.

The overall picture is an audience shaped primarily by comedians and comedy-adjacent actors, with Kimmel's own TV Personality peers largely elsewhere in the graph.
