Listen to the deep-dive discussion –  Chris Hohn’s 53 Billion Dollar Tollbooth Bet. (44:02 min)

“The most important thing is high barriers to entry. If you find a company that is going to be a good company long-term, then you should hold on to it because there’s a persistency of these barriers to entry.”

Nine Positions. $53.6 Billion. Zero Cash.

In February 2026, the 13F filings of TCI Fund Management reveal something extraordinary. Chris Hohn — the British fund manager who runs one of the most successful hedge funds of his generation — manages $53.6 billion in exactly nine positions. No hedges. No cash. Every dollar deployed.

His average holding period is eight years. His annual portfolio turnover is 11%. His top five positions account for 84% of the portfolio. This is extreme concentration — among the tightest in the hedge fund industry at this scale.

Here is the portfolio, as filed on December 31, 2025:

#	Position	Value ($B)	Weight	Category
1	GE Aerospace	14.6	27.3%	Physical monopoly
2	Visa	9.7	18.1%	Information tollbooth
3	Microsoft	8.1	15.1%	Hybrid
4	Moody’s	6.8	12.7%	Information tollbooth
5	S&P Global	6.2	11.5%	Information tollbooth
6	Alphabet	2.7	~5%	Information tollbooth
7	CP Kansas City	2.1	~4%	Physical monopoly
8	CN Rail	1.6	~3%	Physical monopoly
9	Ferrovial	1.1	~2%	Physical monopoly

Two categories emerge. On one side, information tollbooths — Visa, Moody’s, S&P Global, Alphabet — representing 47% of the portfolio. On the other, physical monopolies — GE Aerospace, railways, Ferrovial, Microsoft — representing 53%. Both are excellent businesses with deep moats. But what matters is not what Hohn holds. It’s what he’s doing with it.

The Freesurfer and the Cost of B

To understand the significance of Hohn’s moves, we need a framework. In The Infinite Investor, we decompose every business into two forces: A (the existing operations — the moat, the recurring cash flow, the toll collected today) and B (growth — the secular expansion of the addressable market, the wave that carries revenue forward).

What distinguishes businesses is not the size of B but its cost. When the cost of B is zero — when growth arrives for free — every incremental dollar of revenue falls directly into free cash flow. No new factory, no new fleet, no new patent. This is what we call a Free B: the rarest and most valuable condition in investing.

A business that has a Free B and rides a growing wave of demand without having to build that wave is what we call a Freesurfer.

Visa is the archetype. Visa doesn’t lend money, doesn’t hold accounts, doesn’t take credit risk. It operates a network that processes transactions between issuers and acquirers, collecting approximately 0.13% on each one. Global electronic payment volume grows 8–10% annually. Visa’s revenue grows 8–10% annually. Additional capital required to capture that growth: zero. The same network. More volume. More revenue. Automatically.

Contrast this with GE Aerospace. GE holds one side of the global jet engine duopoly with Pratt & Whitney — a moat as deep as any in the world. But developing a LEAP engine costs $15 billion and takes 15 years. The next engine will cost another $15 billion. The moat is absolute, but growth requires perpetual reinvestment of heavy capital. This is what we call an Accretion Monopoly — a monopoly that grows by accumulating physical capital.

Both are superb companies. But only the first is a Freesurfer. And this distinction produces a natural hierarchy:

Tier	Type	Cost of B	Examples
1	Freesurfer	Zero	Visa, Mastercard, S&P Global, Moody’s, MSCI
2	Hybrid	Moderate	Microsoft (Azure needs data centers), Alphabet (same logic)
3	Accretion Monopoly	High	GE Aerospace, CN Rail, CP Kansas City, ASML

The thesis is simple: capital should migrate up the gradient. From Tier 3 to Tier 1. From atom to bit. From heavy capital to zero capital.

And that is exactly what Chris Hohn is doing.

The Migration: Three Quarters, One Direction

13F filings tell a story when you read them in sequence. This is not a static snapshot. It’s a film in motion.

Q2 2025

Buys: Visa (+2.4 million shares), S&P Global (+730,000), Microsoft (+265,000), Moody’s (+84,000).

Sells: CN Rail (−3.9 million shares), CP Kansas City (−2.1 million), Alphabet (−1.8 million), GE Aerospace (−61,000).

Q3 2025

Massive buy: Visa (+47% of the position, adding nearly 9 million shares). Minor additions to Moody’s and S&P Global.

Sells: Alphabet (−41%), CN Rail (−18%), CP Kansas City (−6%), Microsoft (−6%).

Q4 2025

Buys: Moody’s and S&P Global both increased, doubling down on the credit ratings duopoly.

The pattern is unambiguous. Over three consecutive quarters, Hohn is systematically selling physical monopolies — Canadian railways, infrastructure — and buying information tollbooths. He’s selling good to buy better. He’s trimming Alphabet and Microsoft to concentrate on Visa. He’s moving capital up the gradient.

The critical context: Hohn operates at zero cash. Every purchase is an explicit arbitrage. To increase one position, he must reduce another. In a zero-cash portfolio, every dollar competes permanently with every other dollar. It is the purest conviction test that exists.

And the result of that test, repeated three times in nine months, is always the same: the capital moves up. From rails to tollbooths. From atom to bit. From Tier 3 to Tier 1.

*     *     *

AND, Not OR: The Cooperative Duopoly

The most counterintuitive observation in Hohn’s portfolio is this: he simultaneously holds Moody’s at 12.7% and S&P Global at 11.5%. Combined: 24.2% of $53.6 billion. Thirteen billion dollars in what appears, at first glance, to be two versions of the same company.

Why?

Because Moody’s and S&P Global are not the same company. They share a segment — credit ratings — where they form a duopoly. But beyond that segment, they diverge completely.

S&P Global is a conglomerate of four information tollbooths: credit ratings, indices (the S&P 500 and thousands of others, on which trillions of dollars of passive assets are benchmarked), financial data (Market Intelligence), and Platts (the global benchmark for commodity prices). Four Freesurfers in one ticker.

Moody’s is more concentrated: Moody’s Investors Service (ratings) and Moody’s Analytics (credit risk, compliance, KYC). Everything orbits a single axis — global credit.

But the real insight is in the structure of the tollbooth itself.

When a corporation issues $500 million in bonds, it pays approximately $500,000 to S&P Global AND approximately $500,000 to Moody’s. Not or. AND. Institutional investors demand two ratings. Regulators require it. Every debt issuance pays both agencies. This is a cooperative tollbooth, not a competitive one.

Increasing the position in one does not cannibalize the other. When global debt issuance volume rises, both collect. When it falls, both suffer — but the toll remains mandatory.

The train cannot run on just one.

In Freesurfer terms, this is the purest case imaginable. Two companies jointly levying a mandatory tax on global debt — with zero capital, zero competition between them, and no regulatory alternative. As long as the world issues debt — which is structurally inevitable in a credit-based economy — Hohn collects from both sides.

Zero Cash and the Infinite Option

Hohn’s portfolio runs at zero liquidity. This is not an oversight. It is a statement.

In The Infinite Investor, we argue that cash has a specific and powerful function: it is an Infinite Option — the right to buy at the exact moment when the market offers a gift. A confirmed Freesurfer at a historically low valuation. A tollbooth on sale. The Infinite Option is the ultimate weapon of the patient investor. Buffett holds $325 billion in cash at Berkshire Hathaway precisely for this reason.

Hohn does the opposite. Zero cash. Every dollar at work.

Both are right. The difference is in the mechanics.

Buffett runs a conglomerate that generates cash continuously — insurance premiums, subsidiary earnings. Cash accumulates naturally. Keeping it is an active choice. Deploying it is a rare, decisive event (Apple in 2016, Occidental Petroleum in 2019). The Infinite Option is his structural edge.

Hohn runs a concentrated fund where every dollar must be at work. Cash doesn’t compound. But when he wants to increase a position, he can’t draw from a reserve — he must sell something. And it is precisely this constraint that reveals the hierarchy. When Hohn sells rails to buy information tollbooths, it isn’t tactical rebalancing. It is a value judgment: dollar for dollar, the Freesurfer is worth more than the Accretion Monopoly.

The lesson is the same in both cases. Whether you hold cash or not, the principle doesn’t change: when the  arrives — a confirmed Freesurfer trading 30% below its historical valuation — capital must move. Buffett does it by deploying his reserve. Hohn does it by selling good to buy better. The mechanics differ. The discipline is identical.

Sizing: Conviction Measured in Billions

Hohn’s position sizing is an education in itself. Nine positions. The top five represent 84% of the portfolio. This is extreme concentration.

But the concentration is not random. It reveals a logic of conviction weighted by quality.

The largest bet, GE Aerospace (27%), is his most irreplaceable Accretion Monopoly — the global jet engine duopoly has a near-absolute barrier to entry. But the second largest, Visa (18%), is a pure Freesurfer. And if you combine both sides of the credit ratings duopoly — Moody’s and S&P Global — you get 24.2% of the portfolio. The largest effective position is an information tollbooth.

When Hohn sizes, he isn’t just looking at the quality of the moat. He’s looking at the cost of B. GE sits at 27% because the moat is absolute and the position was accumulated at attractive prices. But the direction of marginal capital — the next dollar, the one Hohn is actively deploying — systematically goes to the Freesurfers. He doesn’t trim GE to buy more GE. He trims rails to build Visa, Moody’s, and S&P Global.

Sizing reveals conviction more honestly than words. And Hohn’s conviction, measured in billions, points in one direction: toward the top of the quality gradient, where the cost of B is zero.

*     *     *

The Prison of Size

There is a Freesurfer that Hohn does not own: MSCI.

MSCI is a remarkably pure tollbooth on global indexing. Two segments only — indices and analytics — with operating margins among the highest in the sector. Every ETF, every passive fund, every institutional allocation benchmarked to an MSCI index pays a royalty. It’s the same model as S&P Dow Jones Indices — but more concentrated. Two segments instead of four. A purer Freesurfer.

Hohn doesn’t buy it. Not because he doesn’t see it. Because he can’t.

MSCI has a market capitalization of approximately $45 billion. To take a meaningful position — say 3% of his fund, or $1.6 billion — Hohn would need to acquire 3.5% of all outstanding MSCI shares. Both on entry and exit, this creates a major liquidity problem. Furthermore, S&P Global owns S&P Dow Jones Indices — Hohn already has his index exposure, bundled in a more liquid ticker.

This is the prison of size. At $53.6 billion, Hohn is constrained to nine positions because each position must absorb billions. Mid-cap names, asymmetric opportunities, smaller Freesurfers — all of it is off-limits.

“Give me $1 million and I guarantee you 50% a year. At $300 billion it’s impossible.” — Warren Buffett

The investor managing $10 million, or $1 million, or $100,000 has a structural advantage that Hohn can never replicate. Size is a moat, but in the other direction: being small is the moat. You can own Hohn’s nine positions plus MSCI, plus high-convexity positions in names Hohn will never touch. You have Hohn’s framework with the flexibility Hohn doesn’t have.

The Gradient Revealed

What Chris Hohn’s portfolio reveals, in real time, with $53.6 billion, is a hierarchy that reasoning alone can derive but empirical evidence makes incontestable.

Even at the summit of quality — in a portfolio where every position is a monopoly or near-monopoly — a gradient exists. And capital always migrates up the gradient. Canadian railways are excellent. Visa is better. GE Aerospace is irreplaceable. The Moody’s–S&P Global duopoly is more irreplaceable still, because it costs nothing.

The discriminant is not the moat. It’s not the barrier to entry. It’s the cost of B. GE has a moat as deep as Visa’s. But GE must reinvest $15 billion per cycle. Visa reinvests zero. In the universe of long-term compounding, this difference is determinative. It is the only variable that separates the very good from the exceptional.

Hohn doesn’t theorize. He acts. He sells good to buy better. And every quarter, the 13F tells the same story: capital moves up. From atom to bit. From heavy capital to zero capital. Toward the top of the gradient.

The capital always migrates up the gradient. Not because physical monopolies are bad — they are excellent. But because in the universe of compounding, the cost of B is the only variable that separates the very good from the exceptional.
