In-N-Out and Whataburger fans do not argue like McDonald's and Burger King customers. They argue like rival faiths. For decades geography kept the peace: In-N-Out stayed west, Whataburger stayed in Texas and the South, and never the Double-Double and the Patty Melt had to share a parking lot.
Updated Aug 31 with a fresh map and the full state-by-state table. The front has grown from 14 contested exits to 19 in five days of data refreshes. This post now tracks the war as it moves.
That peace is ending, and our database can show you exactly where.
Seventeen are in Texas. The other two are in Nashville, Tennessee — In-N-Out's eastern beachhead, planted directly on exits Whataburger had already claimed.
| Metro | The front line |
|---|---|
| Dallas–Fort Worth (12) | I-20 Exits 467A, 467B, 468 · I-30 Exits 68 and 69 (Rockwall) · I-35E Exits 414, 417, 418A, 418B · I-35W Exits 61 and 69 · I-820 Exit 10A |
| San Antonio (3) | I-35 Exit 166A · I-410 Exits 26B and 27 |
| Waco (1) | I-35 Exit 335A — across from Baylor, the college-town flashpoint |
| New Braunfels (1) | I-35 Exit 190B |
| Nashville (2) | I-24 Exits 60 and 60B (Antioch) — the eastern front |
Notice what's missing: California. Whataburger has never crossed into In-N-Out's homeland, which stays a perfect 159 to 0. Every contested exit sits in Whataburger country, and I-35 and its Dallas splits carry nine of the nineteen. But calling this a one-directional invasion turned out to be wrong, because of what the data shows one state west.
Arizona sits directly next to California. It should be In-N-Out country. It is not: Whataburger leads Arizona 24 interstate exits to 15. While everyone watched In-N-Out march east into Texas, Whataburger quietly built the bigger footprint in In-N-Out's own backyard. This is a two-front war where each army is deep in the other's territory, they just have not run into each other in Arizona yet.
| State | In-N-Out exits | Whataburger exits | Contested |
|---|---|---|---|
| California | 159 | 0 | 0 |
| Texas | 15 | 429 | 17 |
| Arizona | 15 | 24 | 0 |
| Tennessee | 6 | 18 | 2 |
| Louisiana | 6 | 23 | 0 |
| Colorado | 10 | 2 | 0 |
| Nevada | 13 | 0 | 0 |
| Oklahoma | 0 | 17 | 0 |
| New Mexico | 0 | 12 | 0 |
| Florida | 0 | 11 | 0 |
The undercards matter too. Colorado has flipped In-N-Out, Oklahoma and New Mexico are solid Whataburger with no red anywhere, and In-N-Out scouts have reached Georgia and South Carolina one and two exits at a time. The Southeast is the next front.
The two Tennessee exits are the tell. In-N-Out's eastward expansion put its first Tennessee locations directly on top of exits Whataburger had already claimed, which means the overlap map is about to grow for the first time in decades. The burger cold war finally has a front that moves. We'll re-run this query as it does.
