The Lithium Triangle in 2026: Codelco Takes Chile, Argentina's RIGI Delivers, Bolivia Still Waits

Three countries hold most of the world's known lithium, and as of mid-2026 they're on three visibly different trajectories: Chile just finished a years-long legal fight over who controls its flagship deposit, Argentina is the only one of the three actually shipping meaningfully more tonnes than a year ago, and Bolivia's ambitious extraction contracts are still sitting in its legislature where they've been since 2024. The price backdrop for all three shifted this year too — lithium carbonate roughly doubled off its trough before pulling back somewhat, for reasons that are more specific and traceable than "the market recovered."

Chile: the Codelco-SQM fight is over

The Chilean Supreme Court rejected Tianqi Lithium's final appeal on January 26, 2026, confirming completion of the merger between state copper giant Codelco and SQM's Salar de Atacama lithium operation — the country's most consequential lithium-policy decision in years, now legally settled rather than pending. The resulting entity, NovaAndino Litio, is where the reporting genuinely diverges: some sources describe a 50:50 structure in which Codelco holds a "golden share" that gives it operational control starting in January 2031, with SQM running operations until then; other reporting describes Codelco taking a 51% controlling stake immediately upon completion. Both versions appear in credible coverage of the same deal, and a single primary filing that reconciles them wasn't confirmed this session — worth verifying directly against SQM's own 6-K filings before citing a specific ownership percentage as settled. What is confirmed: because the joint venture materialized before the end of 2025, SQM secured a quota increase of 300,000 tonnes of lithium carbonate equivalent through 2030, raising its extraction allowance to 1.65 million tonnes LCE for the remainder of its mining lease.

Argentina: RIGI is actually producing tonnes

Argentina's RIGI (Régimen de Incentivo para Grandes Inversiones) investment-incentive regime is the one part of the Lithium Triangle story with hard 2025 output to point to rather than just announcements. Lithium Argentina's Cauchari-Olaroz project produced approximately 34,100 tonnes of lithium carbonate for full-year 2025, and in December submitted RIGI and environmental permits for a Stage 2 expansion targeting an additional 45,000 tonnes per year of capacity. Rio Tinto's Rincón project began exports in 2025, reaching 140 tonnes of cumulative production by the end of October that year — a small base, but Rio Tinto's own 2026 guidance calls for 61,000-64,000 tonnes LCE (its share) from the project, a substantial ramp. Both Rincón and the Cauchari-Olaroz expansion are among the RIGI-approved projects, alongside the Hombre Muerto West lithium project — a real, incentive-backed pipeline with output already landing, not just filings.

Bolivia: still waiting on its legislature

Bolivia's Salar de Uyuni holds some of the largest lithium resources in the world by USGS estimates, but its two flagship DLE contracts — a roughly $1 billion agreement with China's CBC (a CATL subsidiary) and a separate deal with Russia's Uranium One — have been stalled in Bolivia's legislature since late 2024. As of this writing, only the Uranium One agreement has received partial approval; the CBC contract remains unauthorized, with no confirmed timeline. Indigenous communities near the project sites have separately filed legal challenges citing environmental and self-determination concerns over preliminary site activities that began before legislative approval was secured. Any figure describing Bolivia's future DLE output — including commonly cited "by 2030" production targets — should be read as an aspiration tied to contracts that haven't yet cleared Bolivia's own legislature, not a confirmed production plan.

The production and reserves picture, by country

Note the deliberate distinction in that table: "lithium content" tonnes and "lithium carbonate" tonnes are different units, and this piece does not convert between them or between either and LCE — treat any comparison that silently mixes the three as suspect.

The price backdrop

Lithium carbonate priced in China peaked around CNY 181,000/tonne on January 26, 2026 — the same week as Chile's Supreme Court ruling, coincidentally — before pulling back to roughly CNY 165,000/tonne by late March and trading near $20,684/tonne (CIF China/Japan/Korea terms, Fastmarkets) as of April 1, 2026. SMM's own H1 2026 market review attributes the rebound to three specific, named causes: Zimbabwe's suspension of lithium concentrate exports (removing feedstock from Chinese supply chains), supply discipline among Australian spodumene producers following the 2024 price trough, and a resumption of Chinese battery-producer restocking. SMM's outlook flags persistent shortages continuing into H2 2026, with prices likely to rise further — a forecast, not a locked-in outcome, but one grounded in three identifiable market mechanisms rather than sentiment alone.
