Whiplash week. Optics? Copper? Both? Mon AM: Nvidia bets $4B on optics. Mon PM: Credo posts 200% YoY growth on copper. Wed PM: Hock Tan claims 400G/lane works over copper, potentially pushing CPO past 2030. 48 hours of whiplash. Optics? Copper? The answer is both. The question is when....

Dylan Patel believes $NVDA will not use CPO even with Feynman “We’re very bullish on copper and non-CPO optics. We're kinda bearish CPO. $APH is going to perform much better over the next few years than previously expected.” Full quote: “The spending associated with AI chips is currently at or below 10%, but when we move to CPO, networking will grow even further, to 20% or 30%. We are seeing a huge uplift in networking content. CPO is a massive step-function change for the industry, and everyone recognizes it now, but people are getting a little too exuberant. In my view, it is not coming in 2027. It will really arrive toward the end of 2028, with 2029 being the real ramp for scale-up CPO. There have been a lot of manufacturing problems. If we could deploy it today at a good cost, everyone would do it. However, it is really hard. The manufacturing volumes and yields are not there, and the chips are not fully designed for it yet. It is a very complex and difficult technology to ramp, so people are going to stay with copper for as long as they can. That means Rubin is all copper, and Feynman, the next-generation Nvidia GPU after Rubin and Rubin Ultra, is still copper. We are not even shipping Rubin yet. We have a few generations of chips before we get to CPO on the GPU. CPO on switches is coming earlier than on GPUs or AI ASICs. Even without CPO, as cluster sizes get bigger, you need more optics, active electrical cables, and similar components per GPU. We have seen a major shift in the dynamics. On Monday, we released a note for our institutional research subscribers stating that, over the medium term, we are actually very bullish on copper and non-CPO optics, while being slightly bearish on CPO. This is due to delays in downstream chips, such as Feynman not fully utilizing CPO. Copper companies like Amphenol, which make backplane connectors and cables, are going to perform much better over the next few years than previously expected because CPO is being delayed. Ultimately, integrating optics is much more expensive than sending signals electrically. However, electrical signals cannot travel very far without adding repeaters or optics. There is a trade-off continuum, and while CPO will happen, it is currently being pushed out.”

The world needs astronomical amounts of copper over the next 20 years. Here is a collection of televised predictions I made about copper over the past 4 years. It did not require clairvoyance to predict where the price of copper is going. Copper is up again this morning at over $5.00/lb (~$11,000/tonne)

Copper itself is not magnetic. However, the magnetic field causes electrons on the surface of the copper to rearrange themselves and begin rotating. This is the interaction of a magnet and copper. [📹styro.drake]

Rick Rule: Copper is the next bull market - Copper offers the best risk/reward setup - 7% of global copper supply has vanished - In a market already in structural deficit “The copper price has a coiled spring aspect to it” At the same time, it is getting increasingly harder to find new copper deposits. - Grades are lower - Mines are deeper - Risks are rising As a result, exploration and mine development costs are surging. Copper has a bright future

Trump: Boot edge edge…. Grossly incompetent… What they do is take the fiber optics and tried to hook it into copper and fiber and copper don't mix.. It didn't work. You saw that by the helicopter crash. You saw that into the plane.

COPPER HEALS❓️ 📍Copper is known for its antimicrobial properties & is quite capable of replacing antibiotics. When water is stored in a copper bottle for more than 8 hours, the copper releases some of its ions into the water through a process called the oligodynamic effect.

A masterclass on Google's TPU v8 Networking. Two TPU chips? Pssh. We already knew workload-specific silicon was here. But two scale-up networking topologies? That's the actual Google TPU news. Workload-specific interconnects. Think about that. New Semi Doped with Vikram Sekar and Austin Lyons. Copper? Yep. Optics? Yep. What we cover: - TPU splits in two: 8t training, 8i inference. - Virgo: 47 Pb/s scale-out fabric, 100% OCS. - Boardfly scale-up: copper PCB + AECs inside racks, OCS between groups. 16 hops → 7. - Training uses 3D torus (Rubik's Cube). - Inference doesn't. Workload-specific topologies now. - Dragonfly traces to a 2008 paper by Kim, Dally, Scott, Abts. Abts went on to build Groq's interconnect before Nvidia. Chapters: 0:00 Intro 0:21 Two TPUs for two workloads 2:31 HBM, SRAM, and Axion CPUs 7:22 Why networking is the new bottleneck 17:14 Virgo: rebuilding scale-out on optics 25:24 3D torus Rubik's Cube scale-up for training 34:50 Boardfly: scale-up for MoE inference 42:07 Workload-specific everything $GOOGL

While gold dominates the headlines, our largest shareholder, Frank Giustra, believes one of the biggest investment opportunities may be unfolding in copper. After 45 years financing and building mining companies, Frank argues the world is facing a structural copper supply deficit. In his latest interview with Kitco NEWS, Frank discusses: - Why copper demand continues to accelerate - The supply gap the market still isn’t pricing in - How AI and data centres are becoming major copper consumers - The long-term implications for copper producers and developers - Why critical minerals are becoming increasingly strategic For investors focused on the next major commodity cycle, this is an interview worth watching: $CGNT.V $LBCMF

Do you know why they tell you copper is toxic? 🤔 Because copper charges the human body electrically⚡ Your body itself is made mostly of copper + carbon — together they create electricity. Without it, you couldn’t function. That’s why in the 1800s copper was everywhere: 🌿 In gardens to boost plant growth 💧 In water pipes, cups, and cutlery 🏥 In hospitals for healing and recovery 🧿 In jewelry and bracelets to balance energy So how can copper be toxic… When it’s the King of All Minerals? 👑✨ Ask yourself why they never teach you this in school… And why the media demonizes what empowers you. ⚡ Reclaim the power of copper today: 👉 👉

Robert Friedland: If you think we have enough copper you’re dreaming - In human history, we have mined ~700 Mt of copper - In the next 18 yrs, we need to mine the same amount as in the last 10k yrs - And that’s without factoring in renewables, data centers or wars We have all these fancy ideas: renewables, data centers, and EVs… just electrify everything and assume copper will be available. The reality? We haven’t invested in copper for >10 years, meanwhile it is getting harder and harder to find and mine copper. - Since 1900, energy required to produce copper is up 16x - Water consumption is up 2x - Mines are deeper and smaller - Grades are declining We now need more resources to produce the same amount of copper. - 6 Tier-1 copper mines must come online every year for the next 24 yrs - The last major copper mine came online in 2021 - Major copper discoveries are down ~80% over the past 2 decades That’s a long way of saying copper prices must rise to incentivize new production.

One of the most successful mining investors, Frank Giustra, is very bullish on Copper. "The only thing that's going to fix the Copper shortage is a higher price. as we all know in the mining business it could take up to two decades get into production." Got copper?
