Current Ideas & Positions
Meta Platforms
META
Meta is turning WhatsApp and Instagram into a closed-loop payments network. Every in-app checkout starts to look like Visa swipe revenue layered on top of ads—advertising drives discovery, payments capture the transaction, and Meta keeps the whole flywheel inside its apps.

Cloudflare
NET
Cloudflare has become essential internet infrastructure—their verification challenges and security services appear on virtually every website, making them the default layer between users and the internet. As websites need DDoS protection, CDN services, and security, Cloudflare sits at the intersection of traffic, becoming the infrastructure that powers the web. When every site needs protection and performance, and Cloudflare is the default choice, they capture value as the platform that enables the modern internet.

Roblox
RBLX
Roblox is the digital Burning Man—an always-on carnival built by its own community. User-generated content means every world, quest, and virtual good comes from creators, not a studio. That keeps fresh supply flowing, feeds the Robux economy, and gives Roblox operating leverage as it scales. If they march toward a billion participants, you’re looking at a self-funding marketplace that could justify a much larger equity value.

ASML
ASML
ASML is the only producer of machines needed for cutting-edge chips, so most of Europe's semiconductor ambitions depend on their technology. When policymakers consistently reference your technology as a matter of national security, you've moved beyond normal business dynamics. Everyone needs the bridge, and ASML is the only one that can build it—even if the world watches every move.

Figma
FIG
Figma sits at an inflection point in software: while Adobe built design tools for individuals, Figma reimagined them for how teams actually work—collaborative, web-native, and integrated into modern workflows. The bet isn't that Figma will take market share; it's that they've redefined the category. When the next generation of designers grows up on Figma, the question shifts from "should we switch" to "why would we use anything else?"

RDDT
Reddit is one of the most visited sites globally with over 1.3 billion monthly users, yet it’s often overlooked. The bet isn’t about user growth; it’s about monetizing an underutilized asset. With 100,000+ active communities generating authentic conversations, Reddit has become essential infrastructure for how people discover information. As AI companies need high-quality training data, Reddit’s trove of real human discourse becomes increasingly valuable—the conversations happening here are the data that trains the models everyone uses. When a platform reaches this level of embeddedness but remains under-monetized, the opportunity is about capturing value that’s already there.

Alphabet
GOOGL
Google is rebuilding search and YouTube with GenAI, keeping ad slots scarce and pricing power intact. YouTube acts like the only network that matters—it captured the shift from linear TV to streaming with billions of hours of watch time, creator economy at scale, and engaged audiences with measurable results traditional TV can't match. This flywheel funds disciplined bets in Cloud and AI tooling, enabling Google to compete in infrastructure while others struggle to fund AI investments.

VANECK Alternative Asset Manager ETF
GPZ
The VanEck Alternative Asset Manager ETF lets you access alternative asset managers without the constraints of SAFEs or private placements. Those require accredited investor status, lock up capital for years, and limit diversification—this bypasses those barriers while capturing the economics of firms that manage private capital. When access to alternatives is valuable but hard to reach directly, owning the managers who control the capital flows becomes a compelling proxy.

BYD Company LTD
BYDDY
BYD benefits from China's renewable energy infrastructure, but from a different angle: as a vertically integrated EV and battery manufacturer, they capture value across the entire electric mobility value chain. While others buy batteries and components, BYD manufactures them—giving them cost advantages and supply chain control that become more valuable as the energy transition accelerates. The bet isn't just about China's grid; it's about owning the manufacturing capabilities that turn cheap energy into competitive products.

Baidu
BIDU
China's solar build-out now produces more power than U.S. solar and nuclear combined—a shift that changes the economics of compute-intensive businesses. Baidu's AI cloud and robotaxi operations benefit from this grid expansion: cheap renewable energy enables cost-competitive cloud services, while electric robotaxis gain from cleaner, more abundant power. When energy infrastructure becomes a competitive advantage, companies positioned to leverage that infrastructure—rather than fight against it—capture outsized benefits.

CoreWeave
CRWV
Avoid CoreWeave: it’s a short-term play built on hardware that likely won’t last. They’ve loaded up on GPUs to capture current AI demand, but that hardware advantage is eroding fast. GPU rental prices have fallen sharply (H100 chips dropped from $5–6/hour to around 75 cents within a year), and newer architectures offer far more performance. CoreWeave’s core asset—a massive GPU fleet—may be largely obsolete in 5 years as technology shifts toward more efficient, specialized chips. When your entire business model depends on hardware that depreciates this quickly, you’re betting against the pace of innovation.

Enbridge
ENB
Enbridge offers current income through its MLP-like structure despite predictions the structure would change. Energy infrastructure has shown resilience, and the predictable cash flows from pipelines and energy transportation remain valuable. The structure continues to work for income-focused investors, while the underlying energy assets provide a durable foundation. When everyone expects structural change and it doesn't materialize, you get mispriced income streams that persist.

Bitmine Immersion Technologies
BMNR
Bitmine owns a meaningful Ethereum stack, and Chairman Tom Lee is steering it to run both Ethereum staking nodes and Bitcoin miners in its immersion-cooled pods. Ethereum's proof-of-stake shift created staking yields, and as tokenization grows, Ethereum becomes preferred infrastructure—Bitmine's staking captures that while maintaining Bitcoin mining. When crypto or AI workloads spike, their low-power chassis puts them at the front of the line.

Elbit Systems
ESLT
Elbit Systems' advantage is vertical integration—they build the entire defense stack from sensors to platforms to command systems, creating integrated solutions rather than selling components. The moonshot is the shift to autonomous warfare: as conflicts move toward unmanned systems and AI-driven operations, Elbit's ability to deliver complete integrated systems—not just parts—positions them to capture more value. When defense procurement shifts from buying individual components to buying complete autonomous systems, companies that can deliver the full stack become essential partners.

NextVision Stabilized Systems
NXSN.TA
NextVision Stabilized Systems' advantage is their specialization in stabilized imaging and sensor systems—the critical component that makes drones, surveillance, and targeting systems effective. As warfare shifts toward precision autonomous systems and AI-driven targeting, the quality of stabilized sensors becomes the bottleneck. When every drone, vehicle, and platform needs precision stabilization to enable AI vision and targeting, companies that master this specific technology become essential suppliers to the entire defense ecosystem—not just one platform, but every platform that needs to see and aim accurately.

Israel Defense Tech
Israel Defense Tech is unique because it's battle-tested in real conflicts—systems proven under fire, not in simulations. Drones, cybersecurity, and AI systems that work in actual warfare get exported globally, and dual-use technologies transition from defense to commercial markets. When defense tech is validated in combat and becomes the standard for how conflicts are fought, you're investing in the infrastructure of modern warfare.

NVIDIA
NVDA
This was one of my best learning experiences—the first time I touched the stove. I tried to predict short-term geopolitical events when Iran-Israel tensions escalated and there was talk of closing the Strait of Hormuz, which would cut 30% of the world's oil supply. I learned I'm not an oracle of the market, and short-term events—especially geopolitical ones—are nearly impossible to predict with any consistency. The better approach is focusing on long-term fundamentals: companies with durable competitive advantages, structural shifts in industries, and trends that play out over years, not weeks.

SK Hynix
000660.KS (Korea Exchange)
Memory is the future because AI workloads are memory-intensive, and as models grow, memory becomes the bottleneck—not compute. SK Hynix sits at the center of this shift: their HBM and DRAM are essential for training and inference, and the AI boom has created structural demand that goes beyond cyclical patterns. When every major tech company is racing to build AI infrastructure, memory isn't optional—it's the foundation. We're likely in a new cycle where memory demand is driven by a permanent shift in how computing works, not just temporary supply constraints.

Energy
Energy will be the constraint for AI: compute-intensive workloads require massive power, and as AI scales, energy becomes the bottleneck—not just technology. The companies racing to build AI infrastructure are competing for limited energy capacity, and those with access to cheap, abundant power gain a structural advantage. When data centers consume as much energy as entire cities and AI demand keeps growing, energy isn't optional—it's the foundation. We're likely seeing a permanent shift where energy infrastructure determines which regions and companies can compete in AI, not just who has the best chips.

Electricity
Electric utilities sit at the core of AI infrastructure: data centers require large amounts of power delivered through the grid, and as AI scales, transmission and distribution capacity becomes the constraint. Regulated utility companies own and operate the electrical infrastructure that powers AI data centers—the transmission lines, distribution networks, and grid capacity that determines where AI can be built. When every new data center needs grid connections and power delivery, utilities become essential infrastructure. As AI demand grows, these companies can invest in grid expansion and earn returns through the regulated rate base, capturing value as power demand shifts from traditional uses to compute-intensive workloads.

This was part of the same learning experience as NVIDIA—selling out of nervousness during the Iran-Israel geopolitical tensions. When tensions escalated and there was talk of closing the Strait of Hormuz, which would cut 30% of the world's oil supply, I got nervous and sold Vertiv along with Vistra and NVIDIA. I learned I'm not an oracle of the market, and short-term events—especially geopolitical ones—are nearly impossible to predict with any consistency. The better approach is focusing on long-term fundamentals: companies with durable competitive advantages, structural shifts in industries, and trends that play out over years, not weeks. This portfolio documents both successes and mistakes—lessons learned along the way.

IShares Bitcoin Trust ETF
IBIT
Bitcoin is becoming programmable money for the AI age. As AI agents and autonomous systems proliferate, they need a monetary layer that's programmable—settlement that's final, global, and permissionless. Bitcoin's network effect creates a new infrastructure layer: money that AI can use, that exists on the internet, and that operates as reliably as TCP/IP. The iShares Bitcoin Trust provides exposure to what's evolving from a speculative asset into the monetary infrastructure for autonomous agents and global payments. This isn't about digital gold—it's about money becoming a protocol.
