IAAI vs Copart: Which Auction Fits Your Business in 2026?
Both platforms move millions of vehicles per year, but they're not the same. Here's how to decide which one (or both) to use for your sourcing strategy.
The Two Giants
IAAI and Copart together account for the majority of salvage and total-loss vehicle auctions in North America. Both work similarly: insurance carriers, fleets, and dealers consign vehicles, and registered buyers bid online or in person.
But the differences between them matter for your sourcing strategy.
Key Differences
| Factor | IAAI | Copart |
|---|---|---|
| Inventory volume | ~1.5M units/year | ~2M+ units/year |
| Buyer fee structure | Slightly lower on mid-range units | Can be higher on lower-priced units |
| Lot photo quality | Generally more photos per listing | Variable |
| Mobile app | Good, recently updated | Strong mobile experience |
| Storage fees | Competitive | Similar |
| Title processing | 3–7 business days | 3–7 business days |
Who Should Use Which
IAAI tends to work better for:
- Dealers focused on newer model-year vehicles (2015+)
- Buyers who want detailed condition reports
- Markets where IAAI has the closest physical yard
Copart tends to work better for:
- Higher volume buyers (more total inventory)
- Dealers sourcing older or specialty vehicles
- International buyers (Copart has stronger export infrastructure)
Our recommendation: Register for both and run searches across both platforms before committing to a sourcing strategy. The best deal on a specific make/model/year will be on whichever platform has it listed this week.
Fees at a Glance
Both platforms have tiered buyer fees that increase with purchase price. Always calculate total acquisition cost (bid + buyer fee + gate fee + transport) before setting your max bid.
Using Autowalk with Either Platform
Autowalk accepts direct URLs from both IAAI and Copart listings. Paste the URL immediately after winning — the system pulls the vehicle description, lot details, and existing photos to start the marketing generation process while the car is still at the yard.
