The Five Financial Giants Behind America’s Trucking Companies

Why Vanguard, State Street, Fidelity, Capital Group and Wellington—not Walmart or Amazon—belong in the next investigation of power in freight

When people talk about power in trucking, they usually point at the biggest names they can see: Walmart, Amazon, UPS, FedEx, J.B. Hunt or Knight-Swift.

That is understandable. Those companies put trucks on the road, buy enormous amounts of transportation and negotiate freight rates every day.

But that is only the visible layer.

Behind many publicly traded transportation companies sits another class of giant: investment managers whose funds hold significant pieces of multiple carriers, railroads, brokers and logistics companies at the same time.

These firms do not need their names painted on a trailer to matter. Their influence can travel through share ownership, proxy voting, corporate engagement and the permanent pressure public companies face to produce returns for shareholders.

The next five names that deserve serious investigation are:

1. Vanguard

2. State Street

3. Fidelity Investments and its parent, FMR LLC

4. Capital Group

5. Wellington Management

That list is not an accusation that these companies secretly operate trucking companies or coordinate every corporate decision. It is a roadmap for investigating **common ownership**—the concentration created when a small group of investment managers repeatedly appears among the largest shareholders of competing companies.

## Start with the Knight-Swift ownership table

Knight-Swift Transportation is one of the largest trucking companies in North America. Its own 2026 proxy statement gives us a clean look at the structure.

As of the company’s March 16, 2026 record date, Knight-Swift reported the following beneficial owners:

- FMR LLC/Fidelity: 10.0%

- Vanguard: 9.2%

- BlackRock: 8.6%

- Wellington Management: 8.0%

- Dimensional Fund Advisors: 5.0%

Together, those five disclosed positions equal **40.8% of Knight-Swift’s outstanding stock**. By comparison, all 18 current directors and executive officers together were listed at **2.9%**.[1]

That contrast should stop every trucker in their tracks.

It does **not** mean the five outside managers possess a single 40.8% voting block. They manage different funds and accounts, do not necessarily vote alike and have not been shown here to coordinate. “Beneficial ownership” is also a securities-law term that can include authority to vote shares, dispose of shares or both. In many cases, the underlying money belongs to fund investors, retirement savers and institutional clients—not to the asset manager’s corporate treasury.

Still, the table reveals something important: the executives running the carrier are not the only people whose financial interests matter. A small set of outside institutions holds positions large enough that their voting policies, engagement priorities and expectations deserve public scrutiny.

## 1. Vanguard: the unavoidable giant

Vanguard reported **$11.9 trillion in assets under management as of March 31, 2026**, serving more than 50 million investors. Unlike a traditional publicly traded corporation, Vanguard says it is owned by its funds, which are in turn owned by the funds’ shareholders.[2]

In Knight-Swift’s proxy, Vanguard was listed as a 9.2% beneficial owner.[1] Vanguard also repeatedly appears as a major holder across public transportation companies, although a 2026 internal realignment changed how some Vanguard entities report beneficial ownership.[3]

Vanguard belongs at the top of the next investigation because its size is not limited to one carrier. Index investing can make a manager a long-term shareholder across an entire industry. The legitimate question is not, “Does Vanguard dispatch the trucks?” It does not. The question is: **How does a permanent, industry-wide shareholder use its votes and access when it holds significant stakes in companies that are supposed to compete?**

## 2. State Street: smaller than Vanguard, still enormous

State Street reported **$5.6 trillion in assets under management** and **$54.5 trillion in assets under custody or administration** as of March 31, 2026.[4] Those two figures are different—custody is not ownership—but both show the scale of the financial infrastructure sitting behind the public markets.

State Street does not appear among Knight-Swift’s disclosed holders above 5% in the 2026 proxy. So why include it?

Because the investigation is larger than a single carrier. State Street Investment Management operates the SPDR fund complex and is one of the dominant index managers in the world. Its position in the common-ownership debate is important enough that the Justice Department and Federal Trade Commission addressed allegations involving State Street, BlackRock and Vanguard in a 2025 federal coal case.

The agencies did not declare ordinary index investing illegal. They said typical passive investing and ordinary corporate-governance advocacy are generally protected, while using commonly managed shares in competing firms to encourage market-wide output reductions would not be.[5]

That legal line—between passive ownership and anticompetitive use—is precisely why State Street deserves examination rather than careless accusation.

## 3. Fidelity and FMR: the largest disclosed Knight-Swift holder

If the investigation is centered on Knight-Swift, BlackRock is not the largest disclosed institutional holder. Fidelity’s parent, **FMR LLC, is**.

Knight-Swift listed FMR and Abigail P. Johnson at 10.0% beneficial ownership. The filing also reported that FMR had sole voting power over roughly 13.37 million shares and sole dispositive power over roughly 16.30 million shares, based on the cited ownership report.[1]

Fidelity itself reported **$7.0 trillion in managed assets** and **$17.9 trillion in assets under administration** as of March 31, 2026.[6]

Fidelity is often missing from public conversations that reduce everything to “BlackRock and Vanguard.” That omission matters. In Knight-Swift’s own disclosure, FMR’s stake was larger than either BlackRock’s or Vanguard’s.

Any serious investigation should examine Fidelity’s holdings across truckload, less-than-truckload, brokerage, rail, equipment and freight technology—not merely one stock on one filing date.

## 4. Capital Group: the XPO example

Capital Group is another name that rarely reaches the truck-stop conversation, even when its investment organizations rank among the largest holders of a freight company.

XPO’s 2026 proxy listed **Capital Research Global Investors at 9.5%** and **Capital World Investors at 9.4%**. It also listed Vanguard at 9.3%, BlackRock at 8.9% and Invesco at 5.3%.[3]

There is an important caution here: Capital Research Global Investors and Capital World Investors are separate investment organizations within Capital Group, and Capital Group describes its system as distributing investment decisions among multiple independent managers. Their positions should not automatically be added together and treated as one coordinated voting block.

But they should not be ignored either. When two investment organizations under the broader Capital Group umbrella each appear near the top of the same freight company’s ownership table, investigators should examine who makes the investment decisions, who controls proxy voting, what engagement occurs and how independence works in practice.

## 5. Wellington Management: quiet, private and substantial

Wellington Management may be the least familiar name on this list to the general public. It should not be.

Wellington reported more than **$1.3 trillion in client assets under management as of June 30, 2026**.[7] Knight-Swift listed Wellington-related entities at 8.0% beneficial ownership in its 2026 proxy. The filing reported shared voting power over roughly 11.85 million shares for Wellington Management Group and shared dispositive power over roughly 12.92 million shares.[1]

An 8% position in one of North America’s largest carriers is not trivia. It is enough to make Wellington part of the ownership story and a proper subject for questions about proxy votes, governance priorities, executive compensation and engagement with management.

## Why Walmart and Amazon are not on this list

Walmart and Amazon are unquestionably powerful in freight—but they exercise a different kind of power.

Walmart’s leverage comes from being an enormous shipper, retailer and private-fleet operator. It can influence carriers through purchasing volume, contracts, routing requirements and rate negotiations. That is buyer power, operational scale and potential monopsony leverage—not the same common-ownership structure examined here.

Amazon goes even further. Its power comes from vertical integration across fulfillment, warehousing, linehaul, brokerage, air, ocean, final mile, data and its contractor network. Amazon deserves its own investigation into platform control, self-preferencing, contractor dependence and what happens when one company can be shipper, broker, warehouse, carrier network and marketplace at the same time.

Those are major stories. They are simply not this story.

## Ownership is not the same as control—but it is not meaningless

The fastest way to weaken a legitimate investigation is to overstate the evidence.

A large asset manager’s beneficial ownership filing does not, by itself, prove that the manager controls daily operations, sets freight rates, orders layoffs or directs a carrier’s executives. Assets under management are primarily client assets. A 10% position is not the same thing as owning 100% of a subsidiary. And five shareholders with separate governance systems cannot be treated as one actor without evidence of coordination.

That makes BlackRock fundamentally different from Berkshire Hathaway.

Berkshire directly owns and consolidates operating businesses such as BNSF. BlackRock, Vanguard, State Street, Fidelity and Wellington primarily manage investments for funds and clients. Their influence, where it exists, operates through a different channel: votes, engagement, access, capital allocation and the expectations imposed on public-company management.

The responsible claim is not that these firms have been proven to run trucking from a hidden command center.

The responsible claim is this: **ownership in freight is heavily institutional, the same managers recur across competitors, and the public deserves to know how that concentration is used.**

## The questions the trucking industry should be asking

For each major investment manager, investigators should obtain and compare:

- Current and historical holdings across carriers, railroads, brokers, leasing companies and freight technology firms

- Voting authority versus investment or dispositive authority

- Actual proxy votes on directors, executive compensation, mergers and shareholder proposals

- Private engagement policies and documented meetings with transportation companies

- Policies governing competition, consolidation, labor, safety, emissions and executive pay

- Any communications encouraging similar conduct across competing portfolio companies

- Changes in holdings before and after major mergers or industry consolidation

- Whether voting power is centralized, delegated to individual funds or passed through to underlying investors

The distinction matters. Broad diversification is legal. Ordinary index ownership is commonplace. But if a manager uses positions in multiple competitors to promote coordinated conduct that harms competition, regulators have made clear that “passive” labels do not provide unlimited protection.

## Follow the filings, not the logos

The trucking industry has spent decades staring at the companies whose names are printed on equipment. The next layer of accountability requires looking past the logos and into the proxy statements, Schedule 13G filings and voting records.

Start with Vanguard. Then State Street. Then Fidelity/FMR, Capital Group and Wellington.

Do not call them a cartel without evidence. Do not pretend client assets are the managers’ personal property. Do not confuse a minority position with ownership of an operating subsidiary.

But do not dismiss the concentration either.

When five outside managers can collectively appear on a carrier’s ownership table at 40.8% while the company’s entire current leadership group is listed at 2.9%, the right response is not conspiracy. It is scrutiny.

And trucking is long overdue for it.

### Editor’s note on terminology

“Beneficial ownership,” “voting power,” “dispositive power,” “assets under management” and “assets under custody or administration” describe different legal and financial relationships. Percentages in this article come from the cited company proxy statements and may rely on ownership reports filed on different dates. Holdings can change after publication. The article identifies issues for investigation and does not allege that the named investment managers coordinate their votes or control the daily operations of the referenced transportation companies.
