How to Invest in Tungsten When No ETF or Futures Market Exists

The United States has not mined a single pound of tungsten domestically since 2015. This is the same metal required to build Tomahawk missiles, body armour, and armoured vehicles, and adversarial nations now control roughly 87% of the world’s supply.

That vulnerability moved from theoretical to active in early 2026. China halted tungsten exports to Japan entirely from January onward, and the Western benchmark price spiked to $3,000 per mtu (metric tonne unit) at APT CIF Rotterdam.

For a metal you have probably never thought about, tungsten now sits at the centre of a supply squeeze that reaches from munitions factories to the semiconductor lines building AI chips.

The problem for anyone considering a tungsten investment is that the usual tools do not exist here. There is no futures market and no exchange-traded fund tracking the price. What follows here gives you a clear framework for understanding this structural anomaly and evaluating the handful of direct corporate access points actually available on the market today.

The weaponisation of export controls and benchmark spikes

The number to sit with first is the price. Western tungsten reached $3,000 per mtu (APT CIF Rotterdam, 88.5% WO₃) as of the 3 September 2026 assessment, easing slightly from $3,075 per mtu the prior week. To grasp how extreme that is, the US Geological Survey reported Rotterdam APT prices climbing from $331 to $675 per mtu over the year before the 2025 spike began. The market has re-rated by multiples, not percentages.

This did not happen through ordinary supply and demand. It happened by design.

On 4 February 2025, China’s Ministry of Commerce announced export controls covering 25 rare-metal products including tungsten, requiring licences across 20 categories of tungsten-related goods. The stated rationale cited national security and non-proliferation obligations. The timing, immediately following new US tariffs on Chinese imports, told a different story.

The tungsten supply deficit now running through Western markets traces directly to Beijing’s decision to treat export licensing as a foreign policy instrument, compressing available APT volumes at precisely the moment defence procurement cycles are accelerating.

The effect was immediate and severe. According to GACC customs data aggregated by Fastmarkets, APT export volumes collapsed nearly 70%, falling from 782 tonnes in 2024 to just 243 tonnes across the first 11 months of 2025.

Then came the sequenced escalation. China’s 2026 dual-use licensing catalogue explicitly named tungsten products and prohibited military and dual-use exports to Japan. Per NHK World, Chinese APT exports to Japan have registered zero since January 2026, down from 688 tonnes in 2024. It is the first zero reading since records began in 2015.

South Korea felt the pressure next, with Beijing requiring export permits for tungsten used in semiconductors and displays. Two major Japanese chemical producers now face potential production halts of a gas critical to AI chipmaking, showing how far the disruption reaches into advanced technology.

In December 2025, China tightened further, announcing that only 15 approved firms would be permitted to export tungsten across 2026 and 2027.

This is not a commodity cycle. It is a resource cold war, where Beijing squeezes strategic metals to pressure US allies and test whether the West can build supply chains it does not control.

For your portfolio, the read is direct. Any tungsten exposure you take rests on strategic leverage and government response, not on normal price curves. That is precisely why US government funding sits at the heart of the investment case.

Why defence and tech sectors cannot engineer a substitute

If the geopolitics feel urgent, the physics explain why they cannot be engineered away. Tungsten holds the highest melting point of any metal, roughly 3,422 degrees Celsius, paired with extreme hardness and density. No other material combines these properties, and that combination is the entire point.

Where failure is not an option, tungsten has no viable substitute. The applications read like an inventory of modern hard power:

• Armour-piercing shells and munitions, where density and hardness determine penetration.
• Hypersonic and missile systems, where components must survive extreme heat.
• Aerospace turbine blades and thermal shielding, operating far beyond the limits of common alloys.
• Semiconductor tooling and precision cutting, where the metal shapes the chips powering everything else.
• Radiation shielding and radar components, where density does work no lighter metal can.

The US Department of Defense states plainly that tungsten is essential to national security, and the US Geological Survey has classified it as a critical mineral since 2018. It also sits in the National Defense Stockpile. These are not honorary labels; they are the legal foundation for government capital flowing into domestic projects.

Now weigh that necessity against where the metal actually comes from. China controls approximately 81% of global production. Russia and North Korea each add roughly 2.5% to 3%, bringing combined adversarial-nation output to around 87% of the global total.

The United States, meanwhile, produces none. That gap has now run 11 years and counting.

Washington’s critical minerals supply chain strategy increasingly treats government capital deployment through the Defense Production Act and allied financing agencies as the primary lever for rebuilding domestic capacity, with tungsten sitting near the top of the priority list precisely because adversarial concentration is most extreme there.

Here is what this means for you as an investor. Non-substitutability is the floor under the entire thesis. Because no lab can design tungsten out of a missile or a chip line, government interest in domestic supply is not a passing policy mood. It is a structural commitment that gives exploration projects a rationale that survives changes in sentiment.

Navigating a market with no passive options

Once you understand the strategic case, the natural next move is to reach for a fund. Here the market stops cooperating. There is no futures market for tungsten and no tracker ETF offering direct exposure. The standard critical-minerals playbook, buy the ETF and wait, simply does not apply.

That absence is not an oversight. It reflects how tungsten is actually traded, through bilateral contracts and physical benchmark assessments rather than exchange-traded derivatives that institutions can pile into.

How price discovery actually works

Pricing runs through published benchmarks rather than a screen you can trade. The Western reference is the APT CIF Rotterdam assessment, sitting at $3,000 per mtu. Inside China, the SMM domestic APT benchmark was quoted at $78,168 per tonne on 4 September 2026.

Those two numbers, assessed rather than exchanged, are the closest thing this market has to a live price.

The consequence for you is structural. Without a liquid derivatives market, large passive institutional flows cannot enter, which means the smoothing effect of index money never arrives. You are left with individual equities as the only direct route in.

That forces a decision. To gain exposure, you accept single-stock risk and the rigorous due diligence that comes with it. Expect thinner liquidity and sharper volatility than a diversified commodity fund would ever hand you, and size your expectations accordingly before you go looking for the names.

Illiquid junior mining stocks in critical minerals sectors routinely exhibit bid-ask spreads and daily volume constraints that make position entry and exit far more consequential decisions than equivalent moves in large-cap equities, a dynamic that compounds the dilution risk already embedded in these companies’ funding models.

Evaluating the three primary retail entry points

With no fund to hide behind, the entire proposition narrows to a short list of equities. Three companies anchor the US-oriented tungsten thesis developed by John Fenwick of Fenwick Consulting, who began investing in the sector in 2023 and screened partly for a US-supportive orientation.

They differ sharply in government backing and project maturity, and telling those differences apart is the whole game.

Guardian Metal Resources (GMTL)

Guardian is the name with actual government cash in hand. On 23 July 2025, its subsidiary received a $6.2 million non-dilutive grant from the US Department of Defense under Title III of the Defense Production Act, funding pre-feasibility work at the Pilot Mountain tungsten project in Nevada.

The company closed its US IPO on 24 March 2026, raising approximately $21 million through the sale of ADSs at $13.50 each. A July 2026 filing recorded insider buying by the CEO and directors during the price spike, and reporting suggests Guardian is six to nine months ahead of peers in US government engagement.

Kaz Resources (KAZR)

Kaz Resources offers the largest scale and the softest funding. It holds a 70% controlling interest in a joint venture with Kazakhstan’s national miner Tau-Ken Samruk, developing what are described as among the largest undeveloped tungsten deposits globally, and targets 12,000 tonnes per year by around 2030, roughly 15% of 2025 global mine output.

The financing needs a careful eye. KAZR claims $1.6 billion in letters of interest from the US Export-Import Bank and the Development Finance Corporation against a project cost near $1.1 billion. A June 2026 report stressed that no binding loan, guarantee, or equity agreement has been signed. These are intentions, not commitments.

Western Star Resources (WSRIF)

Western Star sits earliest on the risk curve. The company staked its properties in 2020, when tungsten traded near $200 per ton, and holds past-producing ground at its Rowland and White Star projects in Nevada and New Mexico.

The critical caveat is the company’s own. These properties lack a current NI 43-101 mineral resource, the standardised third-party estimate of economically recoverable metal. Historical production is not a resource, and Western Star notes that any production path carries significant uncertainty and risk of failure.

Structural cycle and dilution risks

The upside here is real, and so is the way it can vanish. Critical-minerals juniors are hyper-cyclical, with past cycles producing gains of 10x to 100x followed by drawdowns of 80% to 95%. Rare earth equities recently ran up 500% before collapsing when US-China tensions briefly eased.

A disciplined junior mining investing strategy accounts for the specific pattern of these cycles: equities in hyper-cyclical critical mineral sectors often reach peak valuations on narrative momentum well before underlying projects generate cash flow, which means timing the exit matters as much as identifying the entry.

Two risks deserve particular weight. Timelines are long, with building non-Chinese supply chains historically taking years, and equities can peak well before projects generate cash. And these companies typically fund themselves through repeated equity raises, so weak markets can force highly dilutive financings; one documented comparable saw its share count rise 143.5% in a single year.

When you assess these three, keep the line sharp. Guardian’s grant is cash in the bank. KAZR’s $1.6 billion is a set of non-binding letters. Western Star rests on historical production without a current resource. Those are three different risk profiles wearing the same commodity story.

Structuring a position in an unhedged critical mineral

The tension at the core of this is hard to resolve, and you should not pretend otherwise. The macro case for domestic tungsten is close to undeniable: an 87% adversarial supply chain, zero US production, and a Pentagon writing cheques. The equities carrying that case are small, illiquid, and operationally risky.

Timelines demand patience. Analysts studying rare-earth precedents estimate that meaningfully reducing dependence on China takes 10 to 15 years even with sustained government support and allied coordination. Your capital, if you commit it, is committing to that horizon, not the next quarter.

Watch the catalysts that convert promise into reality. The next meaningful signals are further DoD actions and, critically, whether those Ex-Im and DFC letters of interest ever harden into binding financing. Conversion is the moment the thesis stops being a story.
