BHP vs RIO: How BHP Group and Rio Tinto Compare (2026)

Same yardstick, side by side (as of July 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: RIO 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. BHP and RIO 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 BHP and RIO 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.

BHP Group is a global diversified resources company headquartered in Australia and dual-listed, with a US ADR trading on the NYSE under BHP. Its core businesses are Western Australia iron ore (the largest earnings contributor historically and among the lowest-cost in the world), copper (mines including Escondida in Chile plus operations in Australia and the Americas), metallurgical coal, and a growing potash business anchored by the Jansen project in Canada. BHP reports on an Australian fiscal year ending June 30 and reports in US dollars; in FY2025 revenue was around $51 billion with underlying EBITDA near $26 billion at roughly a 53% margin.

Rio Tinto is a global mining group that digs, processes, and ships the raw materials behind steel, power grids, and batteries. Iron ore from its Pilbara operations in Western Australia is still the profit engine, generating the majority of earnings, while the company also produces aluminum and bauxite, copper (including from the Oyu Tolgoi mine in Mongolia), and, after its 2025 acquisition of Arcadium, lithium. Its two marquee growth projects are the giant Simandou iron ore mine in Guinea, which made its first shipment in late 2025, and a lithium business it aims to scale toward 200,000 tonnes of lithium carbonate equivalent by 2028. RIO shares are American Depositary Receipts representing the London-listed Rio Tinto plc, so U.S. investors get the same underlying economics with dollar-denominated trading.

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

• BHP drivers: Copper as the growth engine; Low-cost iron ore cash engine.
• RIO drivers: Iron ore scale plus Simandou; Copper growth for electrification.

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: BHP's earnings are highly sensitive to iron ore and copper prices, which are driven by Chinese property and steel demand, global growth, and supply from rivals. For RIO, rio's fortunes are tightly linked to iron ore prices, which hinge on Chinese steel demand and property construction, so a slowdown there hits earnings and the dividend directly.

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 BHP if you believe its drivers more; RIO 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 BHP and RIO guides.

BHP. BHP reports on an Australian fiscal year ending June 30 and reports in US dollars. FY2025 revenue fell about 8% to roughly $51 billion on lower iron ore and coal prices, even as copper reached a record. The variable dividend and cyclical earnings mean valuation multiples and yield shift with the commodity cycle rather than staying fixed.

RIO. Revenue and EBITDA both grew in 2025, but reported profit slipped and net debt roughly tripled after the Arcadium lithium acquisition. Shares traded around the low-to-mid $90s at mid-2026 on a trailing P/E of roughly 15, a discount that reflects commodity-cycle risk. The full-year dividend of about $6.5 billion at a roughly 60% payout keeps the yield near 4%.

Headline figures (approximate, JULY 2026): BHP shows revenue (fy2025) ~$51 billion, underlying ebitda (fy2025) ~$26 billion (~53% margin), market capitalization ~$205 billion, dividend yield (adr) ~3.3% to 3.5%; RIO shows revenue (2025) ~$57.6B, underlying ebitda (2025) ~$25.4B, underlying earnings (2025) ~$10.9B, net debt ~$14.4B.

BHP and RIO 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.
