CNI vs CP: Which Is the Better Buy in 2026?
Last updated August 2026
Short answer
CNI (Canadian National Railway Company) and CP (Canadian Pacific Kansas City Limited) share investment themes but are different businesses. The right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
CNI vs CP: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | CNI | CP | What it tells you |
|---|---|---|---|
| Market cap | $76.95B | $78.14B | Size. The larger name is the incumbent; the smaller has more room to grow and more to prove. |
| Forward P/E | 19.88 | 20.82 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 22.92 | 28.95 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 1.00 | 1.22 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 89% of range | 80% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 4.95 | 2.36 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how CNI and CP affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. CNI and CP share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined CNI and CP exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Canadian National Railway Company (CNI) do?
Canadian National Railway Company, headquartered in Montreal, operates a roughly 20,000-mile rail network that is the only one in North America connecting the Atlantic coast (through eastern Canada), the Pacific coast (through Vancouver and Prince Rupert), and the Gulf of Mexico (through New Orleans and Mobile). It hauls a diversified freight mix including grain and fertilizers, petroleum and chemicals, intermodal containers, metals and minerals, forest products, coal, and automotive shipments, connecting Canadian and U.S. producers and ports to domestic and export markets. Revenue comes primarily from freight rates negotiated with shippers, plus fuel surcharges tied to diesel prices, and the company runs a precision scheduled railroading model focused on train speed, asset velocity, and cost per unit moved.
What does Canadian Pacific Kansas City Limited (CP) do?
Canadian Pacific Kansas City Limited (NYSE: CP) operates the only single-line freight railway linking Canada, the United States, and Mexico, a network created by the 2023 combination of Canadian Pacific and Kansas City Southern. The railroad hauls a diversified mix of bulk commodities (grain, potash, coal, fertilizers), merchandise (automotive, forest products, energy, chemicals, plastics), and intermodal containers across roughly 20,000 route miles, with the bulk franchise anchored by Canadian and US grain exports and the merger thesis centered on new cross-border interline traffic between the US Midwest and Mexico. Management runs the network on a precision scheduled railroading (PSR) model focused on asset utilization, network fluidity, and operating-ratio improvement.
CNI vs CP: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- CNI drivers: Efficiency and margin discipline; Three-coast network and export franchise.
- CP drivers: Single-line cross-border network; Precision scheduled railroading and margin gains.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: CN reports in Canadian dollars, so U.S. For CP, cP is economically sensitive: freight volumes track industrial production, grain harvests, energy, and consumer demand, so recessions or trade disruptions directly reduce carloads.
CNI or CP: which should you pick?
CNI vs CP: the full fundamentals
CNI. At roughly 20 to 21 times trailing earnings, CNI trades in line with the North American Class I railroad peer group, reflecting a stable oligopoly business rather than a high-growth premium. Full-year 2025 net income of about C$4.72 billion on C$17.3 billion of revenue implies a net margin near 27%, underscoring the structural profitability of a scaled freight railroad. The near-flat 2026 volume outlook and reliance on productivity for earnings growth are the main factors investors weigh against that valuation.
CP. CPKC delivered record 2025 revenue of ~$15.1 billion with a record-low core adjusted operating ratio near 59.9%, then saw a modest ~2% revenue dip in Q1 2026 on foreign-exchange, fuel, and macro headwinds. The stock trades at a premium to its historical EV/EBITDA range, reflecting its unique network and margin quality. All figures are approximate and drawn from company reports and market data as of mid-2026.
Headline figures (approximate, July 2026): CNI shows revenue (fy2025) ~C$17.3 billion (about US$12.4 billion), net income (fy2025) ~C$4.72 billion (about US$3.4 billion), operating ratio (fy2025) ~61.9% (adjusted ~61.7%), revenue (q1 2026) ~C$4.38 billion (about US$3.19 billion); CP shows revenue (fy2025) ~$15.1B, revenue (q1 2026) ~$3.7B, net income (q1 2026) ~$845M, diluted eps (fy2025) ~$4.51.

FAQ
What is the difference between CNI and CP?
+
Canadian National Railway Company, headquartered in Montreal, operates a roughly 20,000-mile rail network that is the only one in North America connecting the Atlantic coast (through eastern Canada), the Pacific coast (through Vancouver and Prince Rupert), and the Gulf of Mexico (through New Orleans and Mobile). Canadian Pacific Kansas City Limited (NYSE: CP) operates the only single-line freight railway linking Canada, the United States, and Mexico, a network created by the 2023 combination of Canadian Pacific and Kansas City Southern. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is CNI or CP the better stock?
+
Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, CNI or CP?
+
On forward P/E (as of August 2026), CNI trades at 19.88x and CP at 20.82x, so CNI is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both CNI and CP?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of CNI vs CP?
+
CNI: CN reports in Canadian dollars, so U.S. holders of CNI bear currency translation risk on top of the underlying business, and fuel plus foreign exchange were a combined US$0.07 drag on Q1 2026 earnings. Volume guidance is essentially flat, and freight mix shifts have offset same-store price gains, limiting near-term revenue growth. The company is exposed to trade-policy uncertainty, including tariffs and the upcoming USMCA review, which could disrupt cross-border and export freight flows. As a cyclical industrial, CN is sensitive to grain harvests, commodity demand, and broader recession risk, and its precision railroading model faces ongoing labor, regulatory, and service-quality scrutiny across two countries. CP: CP is economically sensitive: freight volumes track industrial production, grain harvests, energy, and consumer demand, so recessions or trade disruptions directly reduce carloads. A large share of revenue is earned in Canadian dollars and Mexican pesos, so foreign-exchange swings and fuel-price volatility create meaningful earnings headwinds (both weighed on Q1 2026). Cross-border exposure adds tariff and trade-policy risk across the US, Mexico, and Canada. The stock also trades at a premium multiple (roughly 22x earnings and mid-teens EV/EBITDA), leaving little room for disappointment if merger synergies or volume growth fall short. Rails additionally carry regulatory, labor, safety, and derailment liabilities that can be costly and reputationally damaging.
