Tony Wang9 min readThe Fast Food 'Competitor' to McDonald's You've Never Heard Of Isn't a Restaurant Company
One PE-owned conglomerate (Sonic + Arby's + Dunkin') controls 11.2% of US fast food listings — almost matching McDonald's 13.0% alone.
Every hidden-consolidation story in this series so far has involved one company operating under multiple names within the same product category — SCI's funeral homes, FirstCash's pawn shop banners, Dollar Tree's now-divested Family Dollar. Fast food adds a version of this that's easy to miss because the brands genuinely compete with each other at the counter, on menu, on price — they just also happen to report up to the same private-equity owner.
"Burger" contaminates descriptions, not just names
| Query (within category=fast_food_restaurant) | Raw match count | What's happening |
|---|---|---|
| q="Burger" | 22,232 | Matches nearly the whole burger-adjacent slice of the category — the word appears in Google's own auto-generated descriptions ("Fast-food burger & fries chain"), not just brand names |
| q="Burger King" | 22,524 | Nearly identical to the bare word "Burger" alone — direct search can't isolate the brand |
| q="King" | 4,844 | Confirms "Burger" is doing all the damage, not "King" |
| q="McDonald's" | 12,004 | Stays clean — a distinctive two-part name with no generic-word overlap |
| q="Wendy's" | 5,707 | Also clean, for the same reason |
McDonald's and Wendy's direct-search totals turn out to be usable because neither name shares a token with a generic word. Burger King isn't so lucky — and unlike this series' earlier contamination cases, the fix here can't rely on the standard "check the bare category word" tell alone, because the collision is happening in auto-generated description copy that Google applies broadly across the category, not just in individual business names.
McDonald's biggest rival isn't a restaurant company
| Domain | Brand | Share of sample | Owner |
|---|---|---|---|
| mcdonalds.com | McDonald's | 13.0% | McDonald's Corporation (public, NYSE: MCD) |
| sonicdrivein.com | Sonic | 8.2% | Inspire Brands (Roark Capital) |
| locations.tacobell.com | Taco Bell | 8.0% | Yum! Brands (public, NYSE: YUM) |
| locations.wendys.com | Wendy's | 7.6% | The Wendy's Company (public, NASDAQ: WEN) |
| burgerking.com | Burger King | 7.0% | Restaurant Brands International (public, NYSE: QSR) |
| dairyqueen.com | Dairy Queen | 5.0% | Berkshire Hathaway |
| chick-fil-a.com | Chick-fil-A | 4.6% | Privately held (Cathy family) |
| restaurants.subway.com | Subway | 4.0% | Roark Capital (as of 2024 acquisition) |
| dunkindonuts.com | Dunkin' | 1.6% | Inspire Brands (Roark Capital) |
| arbys.com | Arby's | 1.4% | Inspire Brands (Roark Capital) |
Sonic, Arby's, and Dunkin' — three brands that occupy different menu categories (drive-in burgers, roast beef sandwiches, coffee and donuts) and compete against completely different sets of rivals at street level — combine for 11.2% of this sample. That's a hair behind McDonald's own 13.0%, and it belongs to a single owner: Inspire Brands, a Roark Capital portfolio company built through acquisitions since Roark took Arby's private in 2018.
Regional density: the South pattern holds, even under population-driven raw counts
Show the full per-capita fast food density ranking
| Rank | State | Listings | Per 1M residents |
|---|---|---|---|
| 1 | Mississippi | 1,019 | 346.2 |
| 2 | Kentucky | 1,500 | 326.9 |
| 3 | Alabama | 1,610 | 312.2 |

| 43 | New Hampshire | 198 | 140.5 |
| 44 | Massachusetts | 875 | 122.6 |
| 45 | Hawaii | 159 | 109.9 |
Texas, California, and Florida lead in raw count, which mostly just tracks population size — but the per-capita view tells the more familiar story from this series: 263.8 fast food listings per 1M residents in the South, versus 191.9 per 1M elsewhere — a 1.37x gap. Mississippi, Kentucky, Alabama, and Oklahoma top the per-capita ranking, the same regional tilt this series has documented in bank branches, pawn shops, dollar stores, and storefront lenders.
How we did this, and the caveats
| What | Detail |
|---|---|
| Category totals | datasets_google_map_facets on category=fast_food_restaurant, country=United States — 68,173 listings (facet), 68,173 in direct category search |
| Chain share | 500-record domain-classification sample, has_website=true, sort=updated_at_desc |
| Chain real-location counts | McDonald's own 2025 10-K (13,706 US restaurants); Sonic's franchise count via Inspire Brands/public reporting (3,129 US stores) |
| Inspire Brands portfolio and ownership | Inspire Brands' own reporting and public coverage of its Roark Capital ownership and 2026 confidential IPO filing |
| Per-capita rankings | State facet counts divided by US Census Bureau Vintage 2024 state population estimates |
Caveats worth stating plainly: the 13.0% McDonald's share and 11.2% Inspire Brands share are sample-relative figures, not national extrapolations. Sonic's 8.2% sample share is very likely an overestimate relative to its true national share — its real US footprint (3,129 stores) is roughly 23% the size of McDonald's (13,706), yet its sample share (8.2%) is nearly two-thirds of McDonald's (13.0%), consistent with this series' repeated finding that a recency-sorted sample can over-represent a chain relative to unrelated factors like a recent listing-refresh event. The Inspire Brands combined total in this post (11.2%, or ~15.2% including Subway) covers only the brands that happen to be tagged fast_food_restaurant — Buffalo Wild Wings, Jimmy John's, and Baskin-Robbins are real parts of the same ownership structure but fall under different categories not counted here, meaning Roark Capital's true combined footprint across all its restaurant brands is larger than what this single-category count can show. And as with every study on this dataset: it's live-growing, so a re-pull after Inspire Brands' potential IPO may show different public-disclosure detail than is available today.

Frequently asked questions
Which fast food chain has the biggest Google Maps footprint?
McDonald's, at 13.0% of a 500-record domain-classification sample within category=fast_food_restaurant. But the second-biggest concentration of market share, 11.2%, doesn't belong to one restaurant brand — it belongs to Inspire Brands, a private-equity owner spread across Sonic, Arby's, and Dunkin', three brands that appear to compete with each other and with McDonald's.
Who owns Sonic, Arby's, and Dunkin'?
All three are owned by Inspire Brands, a portfolio company of private-equity firm Roark Capital, which took Arby's private in 2018 and built the group through subsequent acquisitions. Inspire Brands' full portfolio also includes Buffalo Wild Wings, Jimmy John's, and Baskin-Robbins, and Roark Capital separately acquired Subway in 2024.
Is Inspire Brands going public?
It filed confidentially with the SEC for an initial public offering in May 2026. If it proceeds, a company most consumers have never heard of by name would become a public company at a scale comparable to the individual fast food brands it owns.
Why is category=fast_food_restaurant not a clean 'burger chains' measure?
Because it covers the entire fast-food format, not burgers specifically — Taco Bell, Sonic, Subway, Chick-fil-A, and KFC all share the tag alongside McDonald's, Burger King, and Wendy's. A separate hamburger_restaurant category exists but only captures a small fraction of each major burger chain's real footprint, so it isn't a usable substitute.
Why can't you search directly for 'Burger King' on this dataset?
Because the word 'Burger' saturates the category's own Google-generated listing descriptions, not just brand names — q="Burger" alone (22,232 matches) returns nearly the same total as q="Burger King" (22,524), so text search can't isolate the brand. Domain classification is the only reliable method.
