LTL is a $119B subset. The real market is $270B+ and most carriers can not see it.

Every pallet, every crate, and every mixed-SKU shipment that does not fill an entire truck is commingleable freight. It is freight that can share space or equipment with other shipments moving in the same direction. LTL is the most recognized form, but it is one segment of a much larger market that carriers have historically carved into separate services, separate pricing models, and separate technology stacks.

This article maps the full commingleable freight landscape: what it includes, how big it is, why no single carrier serves it end to end, and what changes when a network treats all partial-load freight as one addressable problem.

1. What Is Commingleable Freight

Commingleable freight is any commercial shipment that can be combined with other shipments on the same vehicle or through the same facility without compromising delivery integrity. The defining characteristic is shared capacity: the shipper does not need an entire truck, and the carrier can consolidate multiple shippers onto one route.

This includes:

• LTL (less-than-truckload): Palletized freight moving through hub-and-spoke or cross-dock networks on shared 53-ft trailers
• Partial truckload (PTL): 6 to 18 pallets, too large for traditional LTL pricing to be competitive, too small to fill a trailer
• Pool distribution: Full truckloads shipped to a regional hub, then deconsolidated and delivered to multiple endpoints on shared routes
• Consolidated last-mile: Multi-stop delivery routes using box trucks, cargo vans, or sprinter vans serving retail stores, restaurants, job sites, or residences
• Big and bulky final mile: Oversized items like furniture, appliances, mattresses, fitness equipment, and building materials delivered to homes and businesses on box trucks with liftgate, threshold, or white-glove service

The common thread is that all of these shipments benefit from network density: more freight moving in the same direction means lower cost per shipment, shorter transit times, and better equipment utilization. They are all commingleable. They have always been treated as separate products.

2. The Five Segments of Commingleable Freight

LTL: The Largest and Most Visible Segment

The U.S. LTL market reached $118.68 billion in 2026 revenue. It is dominated by six public carriers (Old Dominion, FedEx Freight, XPO, Saia, TForce, ArcBest) controlling the majority of a $52.8 billion addressable segment. Every major LTL carrier runs the same model: owned 53-ft trailers, hub-and-spoke terminal networks, union or non-union dock workers, and an operating ratio structure that requires high terminal utilization to generate profit.

LTL works well for freight that fits the 53-ft trailer model: palletized shipments picked up from loading docks, sorted through 2 to 4 terminals, and delivered to another loading dock. It works poorly for everything else.

Partial Truckload (PTL)

Partial truckload sits in the gap between LTL and full truckload. A shipper has 6 to 18 pallets. LTL pricing makes it expensive because weight breaks and freight class calculations penalize larger shipments. FTL is wasteful because half the trailer is empty. PTL is an estimated $55 billion market that neither LTL carriers nor truckload brokers serve efficiently.

The structural problem: LTL carriers price PTL shipments punitively because they consume trailer capacity that could hold 4 to 6 smaller shipments. Truckload brokers price it as a full truck minus a discount. Neither approach reflects the actual cost to move the freight.

Pool Distribution

Pool distribution is a $35 billion segment where a shipper fills an entire trailer at origin, ships it to a regional facility, and a local carrier breaks it into multi-stop deliveries. Consumer goods companies, food and beverage distributors, and retail chains use pool distribution to serve dozens or hundreds of delivery points from a single origin shipment.

Pool distribution eliminates 2 to 4 terminal touches compared to traditional LTL. Freight goes from origin to one regional cross-dock to final destination. The result is lower damage rates, faster transit, and 30 to 40% lower last-mile cost compared to routing the same freight through an LTL terminal network.

Consolidated Last-Mile Delivery

Consolidated last-mile is a $25 billion segment covering multi-stop commercial delivery: retail store replenishment, restaurant supply, construction site delivery, medical equipment distribution, and B2B delivery to locations without loading docks. This freight requires box trucks with liftgates, cargo vans, or sprinter vans, equipment that traditional LTL carriers do not operate.

78% of Warp managed-network shipments use equipment other than 53-ft trailers. This is not an anomaly. It reflects the reality that most commercial delivery points in the U.S. are not equipped with loading docks, and most commingleable freight does not require a 53-ft trailer.

Big and Bulky Final Mile

Big and bulky final mile is a $45 billion segment covering the delivery of oversized, heavy, or non-conveyable items to homes and businesses: furniture, mattresses, appliances, fitness equipment, outdoor furniture, building materials, and commercial fixtures. These items are too large for parcel networks, too awkward for standard LTL palletization, and often require liftgate, threshold, room-of-choice, or white-glove delivery service.

This freight is commingleable because multiple big and bulky orders moving into the same metro area can share a box truck route. A 26-ft box truck carrying 8 to 12 bulky deliveries per route is the standard operating model, not a 53-ft trailer. The carriers who serve this segment are regional box truck operators, not LTL carriers. And the delivery requirements, scheduled appointment windows, photo documentation, assembly options, are fundamentally different from dock-to-dock freight.

E-commerce growth is accelerating this segment. Online furniture, appliance, and fitness equipment sales continue to grow, and every one of those orders requires a delivery vehicle and crew that traditional LTL carriers do not operate. The shipper needs a network with box trucks, liftgates, two-person delivery teams, and route optimization for residential and commercial stops.

3. Why This Market Is Fragmented

Five segments. Five sets of carriers. Five pricing models. Five technology stacks. The reason: each segment was built around a specific equipment type, and carriers organized around equipment.

• LTL carriers own 53-ft trailers and terminals. They do not operate box trucks or cargo vans.
• Pool distributors operate regional delivery fleets but depend on LTL or truckload carriers for linehaul.
• Last-mile carriers run box trucks and vans but have no cross-dock network for sortation.
• Truckload brokers match shippers to capacity but do not handle partial loads or multi-stop routes.
• Big and bulky carriers run box trucks with two-person teams for residential delivery but have no linehaul network or cross-dock infrastructure for upstream consolidation.

A shipper moving 1,000 pallets per month across these segments manages 3 to 5 carrier relationships, 3 to 5 rate structures, 3 to 5 tracking systems, and 3 to 5 claims processes. The operational overhead is enormous. And because each carrier only sees its own slice, no one optimizes across the full freight mix.

This fragmentation is not a technology problem. It is an infrastructure problem. You cannot serve LTL and consolidated last-mile from the same terminal if your terminal only handles 53-ft trailers. You cannot match freight to box trucks if you do not have box trucks in your network. The infrastructure determines what freight you can see.

4. The $270B+ Addressable Market

Here is the math:

Total: $279 billion.

LTL, the segment that every freight technology company targets, is 43% of the commingleable freight market. The majority of the opportunity sits in segments that traditional LTL carriers structurally cannot serve because they do not have the equipment, the facility model, or the routing software to handle anything other than 53-ft trailer freight through terminals.

These are not speculative markets. Partial truckload, big and bulky final mile, pool distribution, and consolidated last-mile are mature, high-volume segments with established demand. They are fragmented across thousands of regional carriers because no national network has been built to serve them at scale.

5. Why LTL Carriers Cannot Serve the Full Market

The structural constraints are not strategic choices. They are consequences of the terminal model:

• Equipment lock-in: LTL carriers own tens of thousands of 53-ft trailers. Their terminals, docks, and yard infrastructure are designed for trailers. Adding box trucks or cargo vans would require a parallel operating system.
• Terminal dependency: Revenue per terminal is the core unit economics metric for public LTL carriers. Every shipment must route through terminals to justify the fixed cost. This makes direct delivery, pool distribution, and multi-stop routes structurally unprofitable.
• Pricing architecture: LTL pricing is built on freight class, weight breaks, and accessorial charges. This pricing model does not apply to pool distribution, partial truckload, or consolidated last-mile. Each segment would need its own tariff structure, its own rating engine, and its own billing system.
• Labor model: Terminal-based LTL requires dock workers, forklift operators, and yard drivers at every facility. Adding multi-modal capability means managing a fundamentally different workforce alongside the existing one.

Old Dominion, the best-run LTL carrier, has a 73.4% operating ratio and 260 terminals. Their infrastructure is optimized for one thing: moving palletized freight on 53-ft trailers through terminals. Expanding into pool distribution or box truck delivery would mean building a second company inside the first one.

6. What a Commingleable Freight Network Looks Like

A network built for commingleable freight looks fundamentally different from a traditional LTL carrier.

Equipment Matching Over Equipment Ownership

Instead of owning a single equipment type, a commingleable freight network manages access to every equipment type through a carrier marketplace. Warp's managed network of 22,246 carriers includes 9,000+ box trucks and cargo vans, sprinter vans, 53-ft dry vans, reefers, and flatbeds. The routing engine matches each shipment to the right equipment based on dimensions, delivery requirements, and route density, not based on what the carrier happens to own.

This is why 78% of Warp shipments use equipment other than 53-ft trailers. The network does not default to trailers. It defaults to the right vehicle.

Cross-Docks, Not Terminals

Terminals are designed for storage and sortation across days. Cross-docks are designed for same-day throughput. A cross-dock facility receives freight, sorts it, and dispatches it within hours, not days. Warp operates 50+ cross-dock facilities with an average dwell time of 0.67 days at the best-performing facility and 85.5% same-day throughput.

Cross-docks handle any equipment type. A 53-ft trailer can dock at the same facility as a 26-ft box truck. Freight can arrive on a trailer and depart on three cargo vans. This flexibility is what makes pool distribution, big and bulky delivery, and multi-modal routing possible through a single network.

One Network, One Rate, Any Mode

The most valuable outcome of a commingleable freight network is simplicity for the shipper. Instead of managing separate carriers for LTL, pool distribution, store replenishment, and partial truckload, one network handles all of it. One API. One rate structure. One tracking system. One claims process.

This is not a theoretical benefit. Warp already serves shippers who use the same network for LTL pallets on 53-ft trailers, store replenishment on box trucks with liftgates, pool distribution through cross-dock deconsolidation, and direct delivery on cargo vans. The freight is different. The network is the same.

7. Why This Matters Now

Three trends are converging to make commingleable freight a definable, addressable market rather than a collection of disconnected segments:

• E-commerce is fragmenting shipment sizes and growing big and bulky. More orders, smaller quantities, more delivery points. The average commercial shipment is getting smaller, pushing freight from FTL into partial truckload, from partial truckload into LTL, and from LTL into consolidated last-mile. At the same time, online sales of furniture, appliances, and fitness equipment are growing double digits, creating massive demand for box truck final-mile delivery that LTL carriers cannot serve. A carrier that only handles one mode loses the shipment as it migrates.
• Retailers are demanding direct store delivery. Major retailers are shifting from DC-to-DC freight (which works on 53-ft trailers) to DC-to-store freight (which requires box trucks with liftgates). Store replenishment volume is growing faster than LTL volume, and it is commingleable freight that traditional LTL carriers cannot serve without surcharging it into unprofitability.
• Software can now do what terminals cannot. AI-powered routing, real-time carrier matching, and automated cross-dock scheduling make it possible to consolidate shipments across equipment types and delivery modes without physical terminal infrastructure. The technology to optimize commingleable freight as a single category did not exist 5 years ago. It does now.

The $279 billion commingleable freight market is not a new market being created. It is an existing market being recognized as one market for the first time. The carriers that serve it will not be the ones with the most terminals. They will be the ones with the most flexible networks.

Frequently Asked Questions

What is the difference between commingleable freight and LTL?

LTL (less-than-truckload) is one type of commingleable freight. LTL specifically refers to palletized freight that shares space on 53-ft trailers through terminal or cross-dock networks. Commingleable freight is the broader category: any shipment that can share equipment with other shipments, including LTL, partial truckload, big and bulky final mile, pool distribution, and consolidated last-mile delivery. LTL is roughly 43% of the total commingleable freight market.

How big is the commingleable freight market?

The U.S. commingleable freight market exceeds $279 billion annually. This includes LTL ($119B), partial truckload ($55B), big and bulky final mile ($45B), pool distribution ($35B), and consolidated last-mile ($25B). These segments are typically served by different carriers, but they share the same underlying characteristic: shipments that benefit from consolidation and network density.

Why don't LTL carriers offer pool distribution and last-mile delivery?

Traditional LTL carriers are structurally built around 53-ft trailers and terminal networks. Their infrastructure, labor model, and pricing architecture are optimized for one equipment type. Pool distribution requires regional box truck and van fleets. Last-mile delivery requires liftgate-equipped vehicles and multi-stop routing. Adding these capabilities would require LTL carriers to operate a second, parallel business alongside their terminal network. Most public carriers have chosen to focus on improving terminal utilization rather than expanding into adjacent freight modes.

What equipment types are used for commingleable freight?

Commingleable freight moves on every equipment type: 53-ft dry vans, 53-ft reefers, 26-ft box trucks with liftgates, cargo vans, sprinter vans, and flatbeds. The right equipment depends on the shipment size, delivery location, and access requirements. 78% of Warp managed-network shipments use equipment other than 53-ft trailers because most commercial delivery points do not have loading docks and most shipments do not require a full-size trailer.

Can one carrier handle all commingleable freight?

A traditional asset-based carrier cannot, because they are organized around a single equipment type. A managed freight network can, because it matches shipments to carriers based on equipment availability, route density, and delivery requirements rather than defaulting to owned assets. Warp serves LTL, pool distribution, store replenishment, and partial truckload freight through a single network of 22,246 carriers and 50+ cross-dock facilities using every equipment type.
