CNP vs DUK: Which Is the Better Buy in 2026?

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.

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. CNP and DUK 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 CNP and DUK 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.

CenterPoint Energy is an energy-delivery holding company headquartered in Houston that operates regulated electric transmission and distribution plus natural gas distribution businesses serving more than 7 million metered customers in Texas, Indiana, Minnesota and Ohio. Its earnings come primarily from rate-regulated operations, where state commissions set allowed returns on the capital CenterPoint invests in poles, wires, substations and gas mains, making the business relatively stable and predictable compared with merchant power generators.

Duke Energy is a holding company for a group of regulated electric and gas utilities serving roughly eight and a half million electric customers across six states, including the Carolinas, Florida, Indiana, Ohio, Kentucky, and Tennessee, plus natural gas distribution to over a million customers. As a regulated utility, Duke earns an authorized return on the capital it invests in power plants, poles, wires, and pipes, so its profit grows largely as it grows its regulated asset base, or rate base, subject to approval from state utility commissions. This regulated model produces relatively stable, predictable cash flows that fund a long-running dividend, which is the core of the income case for the stock.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• CNP drivers: Houston load growth and data centers; Large regulated capital plan.
• DUK drivers: Rate-base growth from a $103B capital plan; Data-center and large-load demand.

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: As a capital-intensive regulated utility, CenterPoint carries substantial debt (enterprise value well above its equity market cap), so rising or elevated interest rates raise financing costs and can pressure the stock. For DUK, duke is highly capital-intensive and carries substantial debt to fund its build-out, which makes it sensitive to interest rates: higher rates raise its borrowing costs and tend to compress the valuations investors assign to regulated utilities, while also making bond yields more competitive with its dividend.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick CNP if you believe its drivers more; DUK if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the CNP and DUK guides.

CNP. CenterPoint trades at a valuation typical of a regulated utility, with a forward P/E around 21x and a trailing multiple in the mid-20s, reflecting its steady, rate-based earnings. Q1 2026 net income was about $316 million ($0.48 GAAP, $0.56 non-GAAP per share), and management reiterated roughly 8% EPS growth for the full year. The dividend yield near 2.2% is on the lower side for the sector, with the total-return case leaning on earnings growth from the capital plan.

DUK. As of late June 2026, DUK traded near the high-$120s per share with a market cap around ~$100 billion. The trailing P/E of roughly ~19x to ~20x is broadly in line with large regulated-utility peers, reflecting steady but moderate earnings growth rather than the higher multiples of faster-growing sectors. Revenue for full-year 2025 was about ~$31.8 billion, and Q1 2026 adjusted EPS was ~$1.93, up from ~$1.76 a year earlier. Figures are approximate, drawn from the Q1 2026 release and public market data, and move with the share price.

Headline figures (approximate, July 2026): CNP shows revenue (ttm) ~$9B, q1 2026 revenue ~$2.98B, 2026 non-gaap eps guidance ~$1.89-$1.91, market cap ~$27B; DUK shows revenue (ttm) ~$31.8B, adjusted eps guidance (fy2026) ~$6.55 to ~$6.80, adjusted eps growth target ~5% to ~7% per year through 2030, dividend yield ~3.4%.

CNP and DUK are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme. Walnut can show your combined CNP and DUK exposure against your real portfolio. It is not an investment adviser.
