No single neighbor dominates McDonald's top 10 — the similarity scores span a tight 0.904 to 0.846, with multiple distinct subcategories all landing within that band. That breadth is the structural finding.

Burger King (0.90) and QSR (0.89) sit at the top, both sharing McDonald's own QSR subcategory, and Subway (0.86) adds a third restaurant neighbor. But the cluster doesn't stay inside food service. Rent-A-Center (0.88) — a home goods and furnishings retailer — is the third-highest match, sitting above every other food brand in the set. Rockstar Games (0.85), a game developer, and Randy Orton (0.85), Lay's (0.85), and Pringles (0.85) round out a top 10 that spans QSR, retail, food brands, and athletes — with no single subcategory accounting for more than three of the ten slots.

The athlete neighbors are worth noting specifically: Randy Orton (0.85) is the highest-scoring celebrity in the set, and his subcategory is Athletes — not a food or restaurant figure. That cross-kind pull, alongside the game developer and home goods retailer, signals that McDonald's audience shape is defined less by food-category loyalty than by a broad consumer profile that overlaps with mass-market entertainment, snack brands, and value retail simultaneously.

The shape here is genuinely broad: no structural spike, no two-peak bridge — just a wide, even distribution of audience overlap across categories that don't obviously belong together.
