The 7investing Podcast

Three massive semiconductor and computing developments are reshaping the future of AI infrastructure — and 7investing's Simon Erickson sits down with Nick Rossalillo of Chip Stock Investor to break them all down. First up: Cerebras Systems (NASDAQ:CBRS), which just went public on May 13th at $185/share (~$40 billion valuation) and is now trading near $46 billion at 90x trailing sales. The company's Wafer Scale Engine, a chip that uses an entire silicon wafer rather than individual diced chip, was designed specifically for AI inference workloads that NVIDIA (NASDAQ:NVDA) GPUs struggle to handle efficiently due to on-chip SRAM limitations. With potential $20 billion in orders from OpenAI and access via AWS, Cerebras is real, but neither Simon nor Nick is buying at this price. Their rule: wait a year before touching a fresh IPO.Next, SpaceX's freshly-raised $75 billion gets put under the microscope, specifically Elon's ambition to build orbital data centers. Nick walks through the SpaceX diagram: 70-meter solar panel wingspan, laser-based networking between compute modules, and the massive engineering challenges around power, heat dissipation, and in-orbit assembly. This isn't imminent, Starlink's next-gen constellation comes first — but if Elon can crack the economics, it would rewrite the rules of data center infrastructure entirely.Finally, Huawei's Tau Scaling announcement: a new architectural approach to chip performance that bypasses the need for extreme ultraviolet lithography (which China can't access due to ASML export controls). Tau temporal scaling focuses on minimizing signal travel time between transistors using logic folding, new materials, and 3D stacking. Huawei claims it could reach 1.5 nanometer equivalent performance by 2031. Simon and Nick are skeptical — 381 chips in six years is not mass production, and TSMC (NYSE:TSM) will be well past that node by then but it's worth watching as China continues building workarounds to Western export restrictions.Whether Moore's Law is dead or simply rerouting, the chipmaking industry is more innovative and more investable than it's been in decades.Join the conversation on the 7investing discord: https://discord.com/invite/PT9ZQqdXXSWant access to all 7investing research?

February 27, 2026: Co-Packaged OpticsGenerative AI is getting very demanding.It's become extremely power-hungry, and that's pushing the physical limits of what today's highest-performing chips are even capable of.One potential solution is co-packaged optics, which involves integrating fiber-optic transmitters directly into the chip. It's a great way to avoid much of the heat and signal degradation that traditionally comes from moving data across inefficient copper wires.Overall, that improves computing performance and uses less power. Which is a big win for this entire sector!But there are also significant costs associated with this new advanced packaging technology. Will the hyperscalers be willing to foot the bill, as the pace of their data center buildouts now approaches light speed?On Friday's show, I was joined by 24/7 Wall Street's Eric Bleeker to discuss the opportunity for co-packaged optics.We described why Lumentum has doubled in price during just the past two months and why Applied Optoelectronics is another stock that should be on your investing radar.⚠️ Not financial advice.

Feb 16, 2026: Why Infrastructure is the Real Winner in the Age of AIWarren Buffett is widely credited with characterizing competitive advantages as moats that companies will aggressively build and will vigorously defend to protect themselves from attacks by others.The software industry has been a popular sector for investors in recent years due to its outsized growth rates and its ability to quickly iterate.Yet the barriers to entry are low here, and it's been difficult for software companies to build sustainable moats.That's perhaps one of the key reasons for the recent "SaaS-pocalypse", where many software stocks have sold off due to the emerging threat of AI and technological disruption.So where do we go from here? Are software stocks with lower prices now a compelling buying opportunity? Or are these falling knives with even more downside risk ahead?On Monday's livestream show, Bastion Fiduciary portfolio manager John Rotonti and I describe the status quo of the software industry. But we also discuss how infrastructure providers are emerging as the real winners in the age of AI.Power, cooling, networking, and other supporting functions are supply-constrained and are doing their best to meet the $3 trillion of AI infrastructure spending that will take place within the next five years. We discuss the turnaround taking place in manufacturing and why Amphenol, TE Connectivity, and Trane Technologies could be lucrative investment opportunities.Timestamps:00:00 – Welcome & Mardi Gras check-in02:30 – The SaaS reckoning: low moats, high competition08:00 – Valuations then vs. now (52x PE → 20x)12:00 – The stock-based compensation problem15:00 – Is it finally time to invest in SaaS?20:00 – Constellation Software: the acquisition machine28:00 – Nvidia & the AI infrastructure buildout38:00 – Hardware + software integration as a moat40:00 – Why Alphabet is the widest-moat AI company43:00 – Power, liquid cooling & the data center arms race47:00 – Labor shortages & re-industrialization50:00 – Audience Q&ALearn more about long-term investing at 7investing.com — get your first 7 days free at 7investing.com/subscribe#7investing #AIStocks #SaaS #Nvidia #Alphabet #JohnRotonti #StockMarket #Investing #AIInfrastructure #IndustrialStocks #ConstellationSoftware #LongTermInvesting

Feb 9, 2026: The Future of the Chip Industry1) Elon Musk wants Tesla to bypass Taiwan Semi and to build his own massive "TeraFab" facilities that would supply 20% of the world's chips.2) Datacenters that are launched into Low Earth Orbit would operate more efficiently with lower temperatures, zero-gravity, and with abundant solar power.3) Meta Platforms' new 5 gigawatt Hyperion AI lab will require more power than the current output of America's largest nuclear power plant.These aren't just science fiction ideas, nor are they purely academic discussions.These are actual projects on the table, which would cost hundreds of billions of dollars and years of dedicated effort to complete.And their technological, commercial, and geopolitical implications would be felt everywhere across the world.I recently spoke with Robert Quinn about the future of the semiconductor industry.Robert has spent three decades advising companies, investors, and institutions on how to design and operate fabs and then to optimize their yields.On our show, we discuss Elon's latest ambitions, whether "the AI Bubble" is actually "an inflection point of demand" and several of the important bottlenecks the industry is facing.We also describe investing opportunities, including chip designer NVIDIA, equipment provider ASML, and quantum innovator IonQ.🔗 Follow Robert Quinn: https://www.linkedin.com/in/robertquinn2020/🔗 Get started with 7investing: https://www.7investing.com (7-day free trial)#semiconductors #elonmusk #AI #chipmanufacturing #tesla #SMR #nuclearenergy #spacetechnology #investing #stockmarket
