OKE vs WES: 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.

Reading it: WES is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

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. OKE and WES 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 OKE and WES 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.

ONEOK (NYSE: OKE) is an American midstream energy company headquartered in Tulsa, Oklahoma. It provides gathering, processing, fractionation, transportation, storage, and marine export services for natural gas, natural gas liquids, crude oil, and refined products across four reportable business segments. The company operates approximately 60,000 miles of pipeline and earns the majority of its revenue through long-term, fee-based contracts that limit direct commodity price exposure. Roughly 90% of 2026 earnings are expected to be fee-based, making cash flow relatively predictable across commodity price cycles.

Western Midstream Partners owns the pipes, compressors, treating and processing plants and water systems that sit between a producer's wellhead and the long-haul market. The footprint is deliberately concentrated: the Delaware Basin in west Texas and New Mexico, the DJ Basin in Colorado, a growing position in the Powder River Basin, and equity interests in a handful of joint-venture pipelines. Second-quarter 2026 set records across nearly every stream the partnership measures, with Delaware Basin natural gas at ~2,140 MMcf/d, produced water at ~2,993 MBbls/d and DJ Basin gas at ~1,547 MMcf/d. Two purchases built that scale in under a year: Aris Water Solutions closed in October 2025 for roughly $1.5B, and Brazos Delaware II closed in June 2026 for roughly $1.6B, split about evenly between cash and newly issued units.

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

• OKE drivers: Fee-Based Revenue Durability; Acquisition Synergy Capture.
• WES drivers: Delaware Basin throughput and the Brazos integration; Produced water as a second fee stream.

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: ONEOK's Net Debt to EBITDA stands at approximately 4x, which is elevated even by midstream standards, and the 2026 adjusted EBITDA guidance range of approximately $7.9 to $8.3 billion was viewed by some analysts as essentially flat versus 2025, raising questions about near-term earnings momentum. For WES, occidental sits on both sides of every material contract as controlling owner, general partner and largest customer, so unitholders depend on a negotiation they take no part in.

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 OKE if you believe its drivers more; WES 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 OKE and WES guides.

OKE. ONEOK's trailing P/E of approximately 15x to 16x sits modestly below its peer group average of roughly 17.5x and well below its own 10-year historical average of approximately 23x, reflecting market uncertainty around integration complexity and a cautious 2026 volume outlook. The EV/EBITDA multiple of approximately 11x is consistent with large-cap midstream peers and suggests the market is pricing in a period of consolidation rather than re-acceleration. Free cash flow of approximately $2.5 billion in fiscal 2025 comfortably covers the dividend, supporting the roughly 76% payout ratio.

WES. Q2 revenue of ~$1,224.7M and net income to limited partners of ~$394.9M came alongside ~$263.6M of free cash flow, and guidance went up on all three of EBITDA, distributable cash flow and free cash flow. On the guidance midpoint the units change hands around 10 times enterprise value to EBITDA, which is roughly where gathering and processing peers trade and well under the multiples midstream partnerships carried before the 2015 reset. The distribution yield near 7.8% is doing most of the work in how the market prices these units, so the coverage ratio and the leverage path matter more here than earnings per unit.

Headline figures (approximate, 2026-06-27): OKE shows revenue (fy 2025) ~$33.6 billion, net income (fy 2025, attributable to oneok) ~$3.39 billion, adjusted ebitda (fy 2025) ~$8.02 billion, diluted eps (fy 2025) ~$5.42; WES shows revenue (ttm) ~$4.33B, q2 2026 adjusted ebitda ~$736.5M, up ~19% year over year, fy2026 adjusted ebitda guidance ~$2.75B to ~$2.95B (raised in August), distribution ~$0.93 per unit quarterly, ~$3.72 annualized, ~7.8% yield at ~$47.94.

OKE and WES 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.
