TeraWulf plans to expand its Muskie site to 1 gigawatt of capacity, according to a Yahoo Finance report that also names SpaceX as considering TSMC as a partner for its "Terafab" initiative. Both items share one theme: access to large-scale power and advanced silicon now determines who can build AI-scale compute infrastructure in the United States.

The 1 GW figure is the concrete anchor of the TeraWulf announcement. One gigawatt of dedicated capacity places the Muskie site among the largest single-location compute builds in the US market. Data center operators typically announce facilities in the tens or low hundreds of megawatts; crossing the 1,000-megawatt threshold moves a project into a category where grid interconnection, cooling and upstream chip supply become the governing constraints, not the server order itself.

TeraWulf built its business on bitcoin mining powered by low-cost energy, and the company has been redirecting that energy-first playbook toward hosting AI and high-performance computing workloads. An expansion at Muskie to a full gigawatt signals that the company intends to compete for AI training and inference contracts that hyperscalers and neocloud providers currently dominate.

What does the 1 GW expansion change for TeraWulf?

Scale changes the customer conversation. AI developers shopping for capacity generally want sites that can absorb hundreds of megawatts on a single interconnection. A 1 GW campus lets TeraWulf bid for those contracts without splitting workloads across locations.

It also changes the risk profile. Projects of this size require:

• Multi-year power purchase agreements negotiated with utilities
• Long-lead equipment: transformers, switchgear and cooling plant
• Committed anchor tenants before construction milestones unlock
• Financing structured against contracted revenue rather than merchant mining income

TeraWulf has not detailed the timetable or the tenant lineup for the full buildout in the reported announcement. The 1 GW figure represents planned capacity for the site rather than energized infrastructure today.

Why would SpaceX talk to TSMC about a "Terafab"?

The second item in the report — SpaceX considering TSMC for a "Terafab" — points at the silicon end of the same bottleneck. TSMC fabricates the overwhelming majority of leading-edge AI accelerators and advanced logic, and any US player planning proprietary compute at scale must secure wafer capacity from the Taiwanese foundry or build alternatives.

The name "Terafab" itself signals ambition: a facility sized for teraflop-class or terawatt-era compute production. SpaceX already operates Starlink, a satellite constellation that functions as an orbital data network, and the company has moved deeper into direct-to-device connectivity. Owning a compute and fabrication pipeline would reduce its dependence on external suppliers for both satellites and AI-driven services.

No deal terms, capacity figures or dates for a SpaceX–TSMC arrangement appear in the report. The item establishes that discussions are under consideration, not that a contract exists.

What connects the two stories?

Both moves treat power and fabrication capacity as strategic assets. TeraWulf is buying scale at the energy layer — a gigawatt under one roof. SpaceX appears to be exploring scale at the silicon layer, where TSMC's process nodes gate access to advanced chips.

For the broader market, the pairing illustrates where leverage now sits in the AI buildout:

• Energy capacity: gigawatt-class sites are scarce and slow to permit
• Silicon supply: leading-edge wafer allocation is booked far in advance
• Vertical integration: operators increasingly want control of both layers

The report does not state whether TeraWulf and SpaceX have any commercial relationship with each other; the two items are separate developments published together.

Market participants tracking AI infrastructure should watch for follow-on disclosures: interconnection approvals for Muskie, anchor tenant announcements at TeraWulf, and any confirmation from SpaceX or TSMC on the scope of a Terafab partnership. Until then, the 1 GW expansion remains a plan, and the TSMC discussion remains exploratory.
