How could Century Aluminum's expansion and production restoration affect Alcoa?
Increased domestic aluminum supply may pressure Alcoa's market share. Century Aluminum is significantly boosting its domestic primary aluminum output through two channels: the restoration of full capacity at its Mount Holly facility and the planned new smelter in Oklahoma. The Oklahoma project, if approved, would double total U.S. primary aluminum production. This substantial increase in supply from a major competitor could intensify market competition, potentially impacting Alcoa's market share and pricing power within the domestic and international aluminum markets.

How it reaches Alcoa
-
Century Aluminum announced plans for a new smelter in Oklahoma, which aims to double total U.S. primary aluminum production and create 1,000 permanent jobs. The company also reported returning to full capacity at its primary smelters, completing major restart projects at Mount Holly, Grundartangi, and Jamalco. This return to full capacity led to a 33% sequential lift in total shipments and net sales of nearly $1 billion in the third quarter of 2026. Financing discussions for the Oklahoma project have advanced, with material terms largely agreed upon ahead of a final investment decision.
The full event1independent outlet -
As a major producer of primary aluminum, Century Aluminum's increased supply from both restored and planned facilities directly increases competition in the U.S. market. This heightened supply environment could put competitive pressure on Alcoa, a key player in the same industry.

Why it matters
The primary aluminum industry is highly sensitive to supply and demand dynamics. For Alcoa, a major global producer, increased domestic supply from a large competitor like Century Aluminum means facing greater market saturation and potential downward pressure on commodity prices. This directly affects revenue and market positioning.
This expansion is part of a broader trend toward strengthening American primary aluminum production. Century Aluminum noted that the company's net cash position and federal manufacturing tax credits provide structural support for its expansion, positioning it as a major force in the domestic supply chain.
What we don't know yet
- Will Century Aluminum secure the final investment decision for the Oklahoma plant?
- How will global demand, driven by data center and power system build out, absorb the increased U.S. supply?
