BHP’s share price (ASX: BHP) has continued to set new all-time highs, the latest mark of A$63.58 capping a 15.32% monthly gain and a 38.5% rally since the start of 2026. The blue-chip name, Australia’s largest by market cap, has captured market attention through a combination of record copper production, upgraded guidance, and the successful conclusion of tense iron ore supply negotiations with China Mineral Resources Group that had threatened one of its key revenue streams.
The rally in BHP shares is being partly driven by copper becoming the company’s primary earnings engine for the first time in its modern history. In its operational review for the nine months ended 31 March 2026, BHP reported record copper output at its flagship Escondida mine in Chile and raised full-year guidance to the upper half of its 1.9 to 2.0 million tonne range. This marked the second guidance upgrade in the first quarter of 2026 alone, signalling both operational excellence and management confidence in sustained production strength.
Copper’s ascendance reflects not just volume growth but also surging prices driven by structural demand from electrification, artificial intelligence data centres, and energy transition infrastructure. According to BHP’s own commodity outlook, the copper market faces a structurally tight supply-demand balance through the late 2020s, with new mine supply constrained by permitting challenges, capital discipline across the industry, and declining ore grades at aging operations.
The company’s half-year results to 31 December 2025, released in February 2026, underscored the copper story with underlying profit beating market expectations. For the first time, copper earnings surpassed iron ore, historically BHP’s cash cow. Management commentary around the results emphasised that new investors were specifically buying BHP for copper exposure, a validation of the strategic repositioning the company has pursued over the past five years.
Iron ore, while no longer the growth driver, remains a formidable cash generator. BHP reported record year-to-date production from its Western Australia Iron Ore operations and reaffirmed full-year guidance of 258 to 269 million tonnes. Critically, on 22 April 2026, BHP announced the successful conclusion of iron ore sales contract negotiations with China Mineral Resources Group, ending a dispute that had escalated in late 2025 when reports emerged that CMRG had asked Chinese steel mills to pause purchases of certain BHP cargoes. The resolution removes a significant tail risk and provides cash flow visibility for the company’s largest business segment by revenue.

Unit cost performance has strengthened across the portfolio. BHP lowered copper unit cost guidance in April, citing operational efficiencies and favourable by-product credits. Iron ore remains at the low end of the global cost curve despite record volumes, preserving margins even as management guides for broadly plateaued seaborne demand over the next few years, with Chinese softness offset by growth in emerging markets and a European recovery.
What Next?
The bull case rests copper demand fundamentals remaining robust, with consensus forecasts pointing to sustained deficits as electrification and AI infrastructure build-outs accelerate. BHP’s copper assets are among the lowest-cost, longest-life operations globally, providing both margin resilience and optionality for expansion. The iron ore business, while not a growth engine, generates substantial free cash flow that underpins dividends and provides downside protection. Then you have BHP’s balance sheet strength and capital discipline, which help differentiate it from peers that overextended during previous cycles.
The bear case centres on valuation and cyclicality. Any softening in copper prices due to weaker-than-expected growth, slower adoption of electric vehicles, or a pullback in data centre capital expenditure could compress both earnings and the valuation multiple. Iron ore, despite operational strength, faces structural headwinds from plateauing Chinese demand and potential new low-cost supply. Project execution risk on major copper and potash developments represents another vulnerability, with cost overruns or permitting delays capable of denting the growth narrative.
