Two Japanese firms just shut down their production line, cutting 25% of the world’s tungsten hexafluoride (WF₆) capacity. This is what Chinese critical minerals dominance looks like in action — slowly choking allies’ high-tech economies
Kanto Denka Kogyo (sometimes referenced with Showa Denko ties) and Central Glass have notified big chipmakers like Samsung, SK Hynix, and TSMC: inventories run out in June, lines shut for good from July 1. Boom — 2,200 tons of annual global WF₆ capacity gone. This specialized gas is essential for depositing ultra-thin tungsten layers in advanced semiconductors (3D NAND, DRAM, logic chips). Without it, fabs slow or stop
Why? China controls ~80% of global tungsten supply and refining. Beijing tightened export controls and licensing on strategic minerals (tungsten included) — hitting Japan hard. Shipments to Japan have plunged, raw material costs spiked, and these specialty gas producers can’t keep operating profitably or at all. Japanese firms were high-quality, reliable suppliers that Korea and others depended on for ~80% of their WF₆ in some cases
This isn’t random. Japanese PM Takaichi hostile posturing against China and plan to remilitarize Japan brought about Chinese sanction of dual use critical minerals (tungsten, rare earths, etc.) to Japanese companies. Higher costs, supply chaos, lost competitiveness, and eventual factory pain ripple through the semiconductor chain. Auto, electronics, defense… all feel it downstream.
Japan’s been diversifying and stockpiling, but decades of over-reliance on Chinese inputs make this a slow bleed. Allies need to accelerate onshoring, friend-shoring, and alternative processing FAST. Relying on an adversary for the guts of your chip industry isn’t strategy — it’s vulnerability
The “just-in-time” global supply chain was efficient until it wasn’t. Now it’s a national security risk. Wake-up call for anyone still sleeping on critical minerals

Dan Dreyfus keeps an incredibly low profile but also is maybe one of the most amazing self made success stories in finance
While the track record is legendary, what is so rare in this industry is what such a good authentic person he is
Never worked for him, but it would be the most obvious job offer to accept if ever given
If AI can help identify new patient populations, uncover overlooked clinical signals, or generate credible new hypotheses, it could shorten timelines while reducing risk. This is one of the main drivers to own NetraMark $AIAI.TO

Exact reason I own NetraMark $AIAI.TO
AI will have the most impact on Pharma. Clinical trials have a failure rate of almost 90%. Even a small impact on this rate will be worth billions.

$LITE rode the first optical wave from $3B to $75B in 2 years time with EML and pluggables.
My thesis is $SIVE can do the same from $3B, with CPO/Pluggables and CW.
Sivers + GFS SiPH reference laser news, alongside the +54% increase today.
Is just one step of the way.
There's a new $SIVE short seller with 0 clue what they're talking about.
1. $MRVL Celestial is likely buying lasers directly with $SIVE as the laser supplier, not through $POET.
As they've been identified as a likely direct customer since 2023.
An analogy is if O-Net / Enablence / Sivers, and O-Net worked directly with $SIVE (which they have) but vertically integrated away Enablence.
They're still likely buying $SIVE lasers.
2. $SIVE is clearly the likely $AAPL supplier for lasers. I use the term likely, because although markets are 99% sure, the BOM is confidential.
The short seller is claiming it's TASC, which I've already identified multiple times as an Apple supplier.
But falsely they're conflating two different generations of Apple Watches with photodiodes and lasers for glucose monitoring to say $SIVE is not a supplier.
3. US NASDAQ listing is likely incoming soon after the new board meeting and shareholder vote.
Upgrading accounting standards and having immaterial changes doesn't mean anything.
4. Ayar labs hasn't scaled up yet. Ayar specifically listed $SIVE as their primary laser supplier in their website.
With their executives going out on statement that they couldn't built their products without $SIVE lasers.
Claiming $SIVE isn't shipping volume to Ayar when their CPO products haven't ramped is stupid.
5. There's zero leak around news for listing. Hilarious coincidence and management has always been pursuing NASDAQ listing since last year.
Short sellers keep repeating this disinformation to try and profit.
6. I've never seen such hilarious BS around Win Semi volume scaling. High confidence in SpaceX and $AVGO supply chain critical foundry.
7. Using arguments from authority saying they know an engineer and then having them confusing architectural differences between $LITE / $COHR and $SIVE is hilarious.
Regardless
-distorting financial statements
-conflating different gen architectures and timeline NRE
- reiterating false accusations
to profit off short term sentiment is likely going to see them turn into a long as CPO/Jabil partnerships volume ramp.
DID YOU LISTEN ANON?
Reuters: New Sivers x GFS strategic collaboration.
$SIVE has now announced its lasers will be integrated into reference designs built on Globalfoundries Silicon Photonics Platform.
For pluggable optical transcivers, CPO, and SiPH.
This is fundamentally the most groundbreaking news for Sivers in history.
As Broadcom, Nvidia, Marvell, AMD, and anyone who goes through GFS silicon photonics has Sivers embedded as a default laser route.
I personally think this news alone should easily 2x or 3x Sivers market cap over the medium term, given how fundamental this is to their revenue.
To have Sivers be the standard laser route for the many hyperscalers that use the world's leading photonics foundry.
People who haven't been to China may not know. Spaces under viaducts are often the most vibrant.
Table tennis courts, dirt bike tracks, basketball courts, people singing and dancing. You almost never see homeless people, druggies, abandoned needles or graffiti.
In a high trust society, the darkest places can be the safest. If criminals are not glorified or in charge of the government.
