Tesla and SpaceX are building a massive new semiconductor manufacturing complex to support AI, Optimus robots, Cybercabs and potentially orbital data centers. Could this create an entirely new source of silver demand—and what happens if it collides with an already tight global silver market?

On August 6, 2026, Texas announced one of the most ambitious manufacturing projects in recent memory: SpaceX’s new Terafab semiconductor complex in Grimes County.

The project represents more than $16.8 billion in capital investment and roughly 100 million square feet of planned manufacturing space—about 3.6 square miles.

Terafab is designed to vertically integrate advanced semiconductor manufacturing, including logic, memory, packaging, testing, AI processors and space-hardened chips. Those chips are intended to power applications both on Earth and in space.

For most people, this is an AI and semiconductor story. For those of us who follow gold, silver and sound money, there’s another question worth asking:

How Much Silver Could This New Industrial Ecosystem Eventually Require?

350–425 MILLION OZT of additional silver demand per year... You’ve probably seen the extraordinary number circulating online. Some versions mistakenly say 350–425 million tonnes. That is impossible.

Global silver mine production is only around 26,000 metric tonnes annually. The figure being discussed almost certainly means 350–425 million troy ounces. Even then, the number is enormous.

Using 2025 global mine production of roughly 846.6 million OZT:

350 Moz = about 41% of annual global mine production

425 Moz = about 50% of annual global mine production

In other words, the aggressive scenario implies that one corporate ecosystem could eventually consume silver equivalent to nearly HALF of everything currently mined worldwide each year. That deserves attention.... It also deserves skepticism.

I have not found any official Tesla or SpaceX forecast stating the companies expect to consume 350–425 million OZT of silver annually. That figure appears to be an outside extrapolation, not a disclosed corporate estimate. The exact number remains speculative, but the underlying industrial trend does not.

What Exactly Is Terafab?

Terafab is not simply another Gigafactory. It is designed to bring large portions of the semiconductor manufacturing process under one roof to support an increasingly interconnected Tesla and SpaceX ecosystem:

• Optimus humanoid robots

• Cybercab and autonomous vehicles

• Artificial intelligence

• Starlink and future AI satellites

• Space-based solar systems

• Starship infrastructure

• Orbital AI data centers

  
  

That last category is where the silver story becomes especially interesting!

SpaceX’s Orbital AI Plans May Be the Biggest Part of This Story

Terafab is huge... But the most important potential silver angle may be what SpaceX wants those chips to eventually power. SpaceX has discussed a long-term ambition of deploying:

100 GIGAWATTS OF ORBITAL AI COMPUTE PER YEAR!

At that scale, the company has talked about transporting roughly:

ONE MILLION METRIC TONNES OF HARDWARE INTO ORBIT ANNUALLY!

Potentially requiring thousands of Starship launches each year. That completely changes the scale of the conversation. We are no longer talking about a few satellites or another generation of consumer electronics.

We are talking about the possibility of building industrial-scale computing infrastructure in space. And those systems need power... A lot of it!

Orbital Data Centers Need Solar Power

A data center on Earth can plug into the grid but a data center orbiting Earth cannot. SpaceX’s orbital computing vision would rely heavily on solar energy, likely using arrays substantially larger than those on conventional communications satellites.

Silver already plays an important role in photovoltaic technology because of its unmatched electrical conductivity and exceptional performance in demanding electrical applications. On Earth, solar manufacturers have worked to reduce the amount of silver used per watt as prices have risen. But space is a very different environment, where reliability, conductivity, weight, thermal performance and resistance to extreme operating conditions can matter far more than simply minimizing material cost.

That raises an important question: If SpaceX eventually builds gigawatt-scale solar-powered computing infrastructure in orbit, how much silver will those space-grade power systems require? We simply don't know yet—but that number could become extremely important to the future silver market. But if orbital AI infrastructure eventually requires tens—or even 100 gigawatts—of newly manufactured solar capacity every year, it could create an industrial demand category that barely exists today.

Terafab may be the factory everyone is talking about today, but the materials demand from what those chips could eventually enable in orbit may prove to be the much bigger story. And the silver content of those future orbital solar arrays may eventually become one of the most important numbers for the silver market to watch.

Possible scenario(s) - Sensitivity test:

Tesla Is Also Designing for Millions of Optimus Robots

Tesla’s terrestrial ambitions are equally aggressive. First large-scale Optimus manufacturing plans have been discussed around eventual capacity of approximately:

1 MILLION ROBOTS PER YEAR

Longer-term Texas plans contemplate capacity potentially reaching:

10 MILLION ROBOTS PER YEAR

A sophisticated humanoid robot contains motors, processors, sensors, cameras, battery-management systems, power electronics, circuit boards, switches, connectors and countless other electrical components.

Many of those categories traditionally use silver. We do not yet know how much silver a finished Optimus will contain.

Possible scenario(s) - Sensitivity test:

These are scenarios, not estimates of actual Optimus silver content. They simply demonstrate why scale matters. At millions of units per year, even relatively modest silver loadings can become meaningful.

Cybercab & EVs Add Another Layer

Tesla Cybercab is a purpose-built, fully autonomous electric vehicle designed specifically for Tesla’s future robotaxi network. Unlike a conventional Tesla, the Cybercab is designed without a steering wheel or pedals, relying on Tesla’s autonomous-driving technology, cameras, AI processors, sensors and sophisticated onboard electronics.

For silver demand, that distinction could matter. A vehicle built from the ground up for autonomous operation could require substantial amounts of computing hardware, power electronics, electrical contacts, sensors and other electronic components—many categories where silver is used. However, Tesla has not disclosed the Cybercab’s actual silver content, so its ultimate silver requirement remains unknown.

Modern electric and increasingly autonomous vehicles already use meaningful quantities of silver in electronics, power systems, sensors, switches and contacts. Estimates for battery electric vehicles often fall around 25–50 grams per vehicle.

At 2 million vehicles annually, that would represent roughly:

1.6–3.2 MILLION OZT OF SILVER PER YEAR

Vehicles alone do not get us near the viral 350–425 Moz estimate. That is not the point.

Vehicles + robots + satellites + solar arrays + AI chips + electrical infrastructure all stack on top of one another. And Tesla and SpaceX are not the only companies pursuing these technologies.

Possible scenario(s) - Sensitivity test:

The Silver Market Is Already Tight

We are not starting from a massive global surplus. The silver market has experienced repeated annual deficits since 2021, and 2026 is on track to become the sixth! Recent figures put 2025 global mine production around 846.6 Moz, while industrial demand alone was roughly 657.4 Moz — and I believe those numbers may be significantly understated.

And here is where the scale becomes much easier to understand:

50 Moz of new annual demand would already exceed the entire projected 2026 market deficit.

100 Moz of new annual demand would equal nearly 12% of 2025 global mine production.

That is why Tesla and SpaceX do not need to consume 425 Moz for this story to matter.

Silver Supply Cannot Instantly Respond

Most of the world’s silver is not produced from primary silver mines. A large percentage comes as a by-product of mining for: Copper • Lead • Zinc • Gold

That creates an unusual supply dynamic. If silver demand suddenly rises 20%, we cannot simply assume miners will immediately produce 20% more silver. A zinc mine does not double production because its by-product silver becomes more valuable. New primary silver mines can also take 10 to 15 years to discover, permit, finance, construct and bring online. That means supply can be slow to respond to a demand shock.

The Biggest Threat to the Bull Case: Thrifting & Substitution

This is the single biggest risk to the extreme silver-demand thesis, and silver bulls should take it seriously.

If silver becomes expensive enough, industry will aggressively redesign products to use less of it.

We are already seeing this in solar through:

• Thinner silver metallization

• Redesigned electrical contacts

• Silver-copper mixes

• Copper-based alternatives

• Higher recycling rates

  
  

If silver eventually reaches $150, $175 or $200/OZT, companies will not passively accept exploding material costs. They will innovate. That is how commodity markets work.

The bullish thesis should not be:

The real question is:

Can New Gold & Silver Demand Grow Faster Than Substitution, Thrifting, Recycling and New Mine Supply Can Respond?

If the answer is yes, which I believe it is, the structural case becomes significantly more interesting. If engineers successfully remove large quantities of silver faster than demand grows, the most extreme forecasts could fail. Any serious silver bull needs to acknowledge both possibilities.

Gold & Silver: Why Space Infrastructure Could Matter for Both

Silver may have the larger volume-demand story, but gold shouldn't be overlooked. Gold's combination of corrosion resistance, conductivity, chemical stability and reflectivity makes it valuable in high-reliability electronics, electrical contacts, connectors and thermal-control applications—especially in aerospace and space.

In orbit, reliability can matter far more than material cost. A failed component hundreds or thousands of miles above Earth may not be easily repaired or replaced. That creates two potentially powerful precious-metals stories:

GOLD = Monetary Reserve + High-Reliability Technology

SILVER = Monetary Metal + High-Volume Industrial Demand

If SpaceX eventually builds orbital computing infrastructure at anything approaching the scale being discussed, investors may need to ask not only how much silver will this require—but how much gold?

What This Means for Physical Silver Stackers

The takeaway is not that Terafab guarantees silver is going to any particular price. And it does not mean SpaceX is about to consume half the world’s silver.

The takeaway is more fundamental:

Another Potentially Significant Industrial Demand Category Is Emerging While Silver Supply Is Already Relatively Constrained.

🔥 Terafab is one project.

🔥 Optimus is one product.

🔥 Cybercab is one platform.

🔥 Orbital data centers are one potential new industry.

Together they point toward a world that will require dramatically more:

🔥 Electrical infrastructure

🔥 Computing

🔥 Automation

🔥 Solar power

🔥 High-performance electronics

Silver does not need to dominate every one of these technologies for their aggregate effect to become meaningful. And Tesla and SpaceX are not alone. They are simply among the most visible companies pushing in this direction. Could an extreme scenario eventually approach one billion ounces of annual silver demand? Mathematically, yes. Is there enough evidence today to say that will happen by 2032? NO.

That belongs firmly in the extreme bullish scenario category. At those levels, the market itself would likely change through:

🔥 Higher recycling;

🔥 New mine investment;

🔥 More aggressive thrifting;

🔥 and faster substitution.

But the extreme scenario does not need to happen.

Even 50–100 Moz of additional annual demand could be meaningful in a market producing less than 900 Moz from mines each year.

And if several industries create incremental demand at the same time, the effect could compound!

My Take as a Gold & Silver Stacker

I am not interested in this story because I believe one factory in Texas is about to consume half the world’s silver. I am interested because:

The List of Technologies Requiring Enormous Amounts of Electrical Infrastructure Keeps Getting Longer While the Silver Market Remains Relatively Small.

🔥 Terafab is another data point.

🔥 Optimus is another.

🔥 Cybercab is another.

🔥 AI data centers are another.

🔥 Orbital computing could become another.

None of those guarantees dramatically higher silver prices. But together they reinforce a long-term trend:

The world keeps finding new strategic uses for a metal that is difficult to rapidly produce more of.

The viral 350–425 Moz estimate remains unproven. That does not diminish what Tesla and SpaceX are actually attempting. SpaceX has discussed a future involving as much as 100 GW of new orbital computing capacity annually. Tesla is simultaneously pursuing millions of humanoid robots, autonomous vehicles and increasingly vertically integrated semiconductor production. Meanwhile, silver is entering what is forecast to be its sixth consecutive annual market deficit.

Tesla and SpaceX do not need to consume the world’s entire silver supply for this to matter. They simply need to become one more major source of demand in a market already struggling to balance supply and consumption. And if SpaceX begins moving toward anything remotely resembling its full orbital-compute ambition, the silver content of its satellites, solar arrays, electronics and electrical systems could become one of the most important numbers for silver investors to watch.

Because then we are no longer talking about another phone, another car, or another data center...

We are talking about:

BUILDING INDUSTRIAL INFRASTRUCTURE IN SPACE AT A SCALE HUMANITY HAS NEVER ATTEMPTED BEFORE.

And silver will have a role to play... Potentially, a very big one.

FAQ: Tesla, SpaceX, Terafab & the Potential Silver Demand Shock

What is Tesla and SpaceX’s Terafab?

Terafab is a massive planned semiconductor manufacturing complex in Texas designed to vertically integrate advanced chip production. The chips could support Tesla Optimus robots, Cybercabs, AI computing, Starlink, SpaceX spacecraft and potentially orbital AI data centers.

Why could Terafab matter for silver?

Terafab itself is only part of the story. The technologies it could support require enormous amounts of electronics, electrical infrastructure, power systems, solar generation and advanced computing hardware—all areas where silver can play an important role. The bigger question is not simply how much silver the factory uses, but how much silver could eventually be required by the products and infrastructure its chips enable.

Will Tesla and SpaceX really need 350–425 million OZT of silver per year?

We don't know. The 350–425 million OZT annual silver-demand estimate is NOT an official Tesla or SpaceX forecast. It appears to be an outside extrapolation based on aggressive assumptions about future robots, vehicles, orbital computing, solar generation and other infrastructure. The figure should therefore be viewed as an extreme scenario to investigate—not an established forecast.

What would 350–425 million OZT of silver actually represent?

Using global silver mine production of roughly 846.6 Moz in 2025:

• 350 Moz = approximately 41% of annual global mine production

• 425 Moz = approximately 50% of annual global mine production

That demonstrates how extraordinary the claim is. Tesla and SpaceX would not need to reach anything close to those levels for incremental demand to become meaningful to the silver market.

How many metric tonnes is 425 million OZT of silver?

Approximately 13,219 metric tonnes.

For comparison:

• 350 Moz ≈ 10,885 tonnes

• 400 Moz ≈ 12,441 tonnes

• 425 Moz ≈ 13,219 tonnes

  
  

This is why claims of 350–425 million tonnes are clearly incorrect. The circulating figure almost certainly refers to millions of troy ounces, not tonnes.

What are SpaceX orbital data centers?

SpaceX has discussed the possibility of deploying massive amounts of computing infrastructure in orbit. Instead of operating entirely inside terrestrial data centers, advanced computing hardware could potentially operate aboard satellites powered largely by solar energy. The long-term vision discussed by SpaceX could eventually reach as much as 100 GW of orbital computing deployment annually.

Why could orbital data centers require silver?

Orbital computing infrastructure would require far more than AI chips. Potential requirements include solar power generation, electrical connections, power-management systems, advanced electronics, spacecraft and high-reliability electrical components. Silver has the highest electrical conductivity of any metal, making its potential role in high-performance electrical systems particularly interesting.

Exactly how much silver future SpaceX orbital infrastructure would require remains unknown.

How much silver could 100 GW of orbital solar require?

SpaceX has not disclosed the silver intensity of its future orbital power systems, so any calculation is hypothetical. For example, if 100 GW of annual orbital solar deployment required:

• 5 tonnes/GW → ~16.1 Moz

• 10 tonnes/GW → ~32.2 Moz

• 20 tonnes/GW → ~64.3 Moz

• 30 tonnes/GW → ~96.5 Moz

• 50 tonnes/GW → ~160.8 Moz

These are scenarios designed to illustrate scale—not forecasts of actual SpaceX silver consumption.

Can copper simply replace silver in orbital solar systems?

That cannot currently be assumed. Terrestrial solar manufacturers have incentives to reduce silver use and investigate alternatives such as copper. However, space-based systems face very different engineering requirements, including extreme temperatures, radiation, vacuum, weight constraints, reliability and long operating lifetimes. Until SpaceX reveals the architecture of its future orbital power systems, we do not know how much silver—or what alternative materials—they will require.

What is Tesla Optimus?

Optimus is Tesla's humanoid robot platform. Tesla has discussed producing Optimus at enormous scale, potentially reaching millions of robots annually over the long term. Each robot could require sophisticated electronics, sensors, processors, motors, power-management systems, switches and electrical connections.

Tesla has not disclosed the amount of silver contained in an Optimus robot.

How much silver could Tesla Optimus require?

Because Tesla has not disclosed actual silver content, the article uses hypothetical scenarios. At 1 million Optimus robots annually:

• 25 grams/robot → ~0.8 Moz

• 50 grams → ~1.6 Moz

• 100 grams → ~3.2 Moz

• 250 grams → ~8.0 Moz

• 500 grams → ~16.1 Moz

At 10 million robots annually, those scenarios range from approximately 8 Moz to 160.8 Moz.

Again, these figures illustrate potential scale and are not estimates of actual Optimus silver content.

What is Tesla Cybercab?

Cybercab is Tesla's purpose-built autonomous electric robotaxi. It is designed around autonomous operation rather than traditional human driving controls. That means Cybercab could contain substantial computing, sensors, power electronics, electrical contacts and other sophisticated electronics. The actual amount of silver per Cybercab has not been disclosed by Tesla.

How much silver could 2 million Cybercabs require?

Using hypothetical silver loadings:

• 25 grams/vehicle → ~1.6 Moz

• 50 grams → ~3.2 Moz

• 75 grams → ~4.8 Moz

• 100 grams → ~6.4 Moz

• 150 grams → ~9.6 Moz

  
  

These are scenario calculations rather than forecasts of Cybercab's actual silver content.

Why would an additional 50–100 Moz of silver demand matter?

Because the silver market is relatively small. An additional 50 Moz of annual demand would be comparable to or greater than an entire recent annual silver-market deficit, while 100 Moz would equal roughly 12% of 2025 global mine production. That means the extreme 350–425 Moz scenario does not have to come true for new technology demand to potentially matter.

Why can't silver miners simply produce more silver if demand increases?

Much of the world's silver is produced as a by-product of copper, lead, zinc and gold mining. That means higher silver prices do not automatically result in an equivalent increase in silver production. New primary silver mines can also require years to discover, permit, finance, construct and bring into production, potentially making supply relatively slow to respond to sudden demand growth.

Could manufacturers reduce their silver consumption?

Yes. This is one of the most important risks to extremely bullish silver-demand projections. As silver becomes more expensive, manufacturers have stronger incentives to thrift silver, redesign products, increase recycling and substitute other materials where technically practical. The key long-term question is whether new demand from AI, robotics, electrification, solar and potentially orbital computing grows faster than thrifting, substitution, recycling and new mine supply can respond.

Why is silver different from gold in this story?

Both could benefit from expanding space infrastructure, but in different ways:

GOLD = Monetary Reserve + High-Reliability Technology

SILVER = Monetary Metal + High-Volume Industrial Demand

Gold is critical in high-reliability electronics and space applications, while silver’s exceptional conductivity makes it important across solar, electronics and electrical infrastructure.

Could Tesla and SpaceX eventually consume the world's entire annual silver supply?

It is mathematically possible to construct an extreme scenario approaching one billion OZT of annual demand, but there is currently not enough evidence to forecast that Tesla and SpaceX will actually reach those levels. At anything approaching that scale, higher prices would also encourage more recycling, mine development, thrifting and substitution. The “entire world's supply” scenario should therefore be treated as an extreme bullish scenario rather than a base-case forecast.

What is the biggest takeaway for silver stackers?

Tesla and SpaceX do not need to consume half the world's silver for this story to matter. The more important development is that AI, robotics, autonomous vehicles, advanced computing and potentially orbital infrastructure could create new sources of industrial demand at a time when the global silver market is already relatively tight. The numbers worth watching going forward are the actual silver loadings in Optimus, Cybercab, advanced solar systems and SpaceX's future orbital infrastructure.

Why do many stackers use Dollar Cost Averaging?

Many long-term stackers use Dollar Cost Averaging because it avoids trying to perfectly time the market. When prices fall, the same dollar amount purchases more troy ounces. When prices rise, fewer ounces are purchased. Over time, this can lower the average cost per troy ounce.
