The 2028 Global Intelligence Crisis

"What if our AI bullishness continues to be right... and what if that's actually bearish?"

A fictional-but-rigorously-researched macro memo written from June 2028, looking back at a financial crisis triggered by AI's overwhelming success. The thesis: AI exceeds all expectations, corporate margins explode, the S&P hits 8,000 by October 2026 โ€” then the economy collapses anyway. Machines don't spend money. White-collar workers lose jobs and stop consuming. The entire consumer economy quietly implodes in what the authors call the "Human Intelligence Displacement Spiral."

CRDO: The AI Data Center Connectivity Play

"The biggest bottleneck in AI isn't chips anymore โ€” it's the wiring between them."

Credo Technology (CRDO) makes high-speed Active Electrical Cables (AEC) and optical DSP chips that move data between GPUs, switches, and servers inside AI data centers. As NVDA's Blackwell GPU clusters scale to hundreds of thousands of chips, the bandwidth connecting them becomes the critical constraint โ€” and Credo's HiWire AEC is gaining share as a lower-power, lower-cost alternative to traditional optical fiber at short distances.

MRVL: The Custom AI Chip Architect

"While NVIDIA dominates off-the-shelf AI compute, Marvell is quietly winning the custom silicon war โ€” building bespoke AI chips for Google, Amazon, and Microsoft."

Marvell Technology (MRVL) is a semiconductor company pivoting aggressively toward custom AI ASICs (Application-Specific Integrated Circuits) for hyperscalers. As Google, Amazon, and Microsoft seek to reduce dependence on NVDA by building their own AI chips, they turn to Marvell to design and supply them. This is a high-margin, sticky business with multi-year design win cycles โ€” and Marvell's AI revenue is growing explosively.

AVGO: The AI Infrastructure Empire

"Broadcom is the quiet monopolist of AI infrastructure โ€” every hyperscaler building custom AI chips relies on Broadcom's networking silicon, and Google's TPU is built on Broadcom's custom ASIC expertise."

Broadcom (AVGO) operates two high-margin businesses that are both accelerating with AI: custom AI ASICs (building bespoke AI chips for Google, Meta, and ByteDance) and networking silicon (Tomahawk and Jericho switches that connect GPU clusters). On top of this, the $69B VMware acquisition has transformed Broadcom into a dominant enterprise software player, adding a recurring subscription revenue stream with 70%+ gross margins.

What to Watch โ€” March 4 Earnings

Analysts expect EPS ~$2.02 and Revenue ~$19.1B. The key signal is AI revenue guidance โ€” Broadcom guided for $60โ€“90B in AI revenue by FY2027 from just three hyperscaler customers. Any update to this range, plus VMware renewal rates, will drive the stock. Current price $319.55 implies ~42% upside to the $455 analyst consensus target.

Key Risk

Stock is down ~23% from its 52-week high of $414.61. Heavy customer concentration in AI ASIC business (Google, Meta, ByteDance) means any hyperscaler capex pullback would hit disproportionately. VMware integration execution risk also remains.

MDB: The AI Data Layer Nobody Is Talking About

MongoDB just got crushed 22โ€“25% on earnings โ€” but the selloff is a guidance reset, not a business breakdown. Q4 revenue grew 27% to $695M, beating estimates by 4%. Atlas (the cloud product) grew 29%. The problem: Q1 guidance missed by $0.02โ€“$0.06 EPS, and two sales leaders are departing. The market punished a great business for a small forward miss.

What MongoDB Does

The world's dominant document database โ€” flexible JSON-style data storage that modern apps (AI, e-commerce, IoT) need. 45% NoSQL market share. 65,200+ customers. Atlas is the cloud-hosted version, usage-based pricing.

The AI Bull Case

MongoDB's vector search capability makes it the natural database for RAG (retrieval-augmented generation) AI apps โ€” the architecture every LLM deployment uses to query private data. AI adoption accelerates MongoDB's growth, not disrupts it.

Why It Got Crushed

Q1 EPS guidance $1.15โ€“$1.19 vs. $1.21 estimate. Atlas growth decelerating from 29% to 21โ€“23% for FY2027. Two top sales executives departing simultaneously. Classic "sell the guidance" overreaction โ€” 31 of 42 analysts still rate Buy.

Photonics IDMTier 1 ยท Highest ConvictionNVIDIA GB200 Supplierโš  GTC UPDATE ยท Mar 17
Coherent Corp. ยท COHR ยท Optical Picks

COHR: The Most Vertically Integrated Photonics IDM

GTC Update (Mar 17, 2026): COHR spiked ~10% on the $2B NVIDIA supply deal (through 2030), then gave back gains after Jensen Huang's GTC keynote confirmed NVIDIA will continue using copper cables (ACC) in near-term Blackwell and Vera Rubin systems. Co-packaged optics (CPO) โ€” where COHR has its deepest moat โ€” is now a 2027โ€“2028 revenue story, not 2026. The bull case is intact; the timeline is longer. This pullback is a better entry point than last week's spike.

Coherent Corp. is the highest-conviction name in the photonics supply chain because it owns both the laser IP and the fab โ€” the exact combination the author of the Photonics Boom article identifies as the source of durable value creation. Coherent operates the world's largest 6-inch Indium Phosphide (InP) wafer fab, giving it a 4x manufacturing cost advantage over competitors still on 2-inch or 4-inch wafers. That fab is not replicable in under 5 years. NVIDIA's $2B investment and supply agreement through 2030 provides a durable revenue floor.

vs ~$82 today

The IDM Moat: Coherent designs and manufactures its own InP lasers โ€” the active light-emitting components inside every 800G and 1.6T transceiver. Competitors that buy lasers from third parties are at Coherent's mercy on pricing and supply. As AI cluster density increases (800G โ†’ 1.6T โ†’ 3.2T), the demand for InP lasers grows exponentially, and Coherent's 6-inch fab is the only facility in the world that can scale to meet it at competitive cost.

The Risk: COHR trades at ~251x trailing P/E โ€” expensive by any traditional measure. Jensen Huang's GTC comments (Mar 17) confirmed CPO revenue ramp is 2027โ€“2028, not 2026 โ€” the market is repricing the timeline. The bull case requires continued hyperscaler capex growth and a successful 800Gโ†’1.6Tโ†’CPO transition. If AI capex slows or the CPO transition is further delayed, the multiple compresses sharply. The $2B NVIDIA deal through 2030 provides a floor. Size accordingly and be patient on the CPO thesis.

AXT Inc. ยท AXTI ยท Speculative Picks

AXTI: The InP Substrate Chokepoint โ€” The CRDO of Raw Materials

Every 800G and 1.6T transceiver that COHR, LITE, and ALAB make requires Indium Phosphide (InP) wafers as the raw substrate. AXT Inc. is one of the only companies in the world that manufactures these wafers at commercial scale. With a 70% supply gap in InP substrates โ€” orders booked through 2026, 18โ€“24 month equipment lead times to add capacity โ€” AXTI sits at the most acute bottleneck in the entire photonics supply chain. This is the CRDO thesis applied one layer deeper: not the transceiver, but the raw material the transceiver is built from.

The Chokepoint Thesis: InP is not silicon. It cannot be grown in standard semiconductor fabs. It requires specialized MOCVD (metal-organic chemical vapor deposition) reactors that take 18โ€“24 months to procure and qualify. AXT has spent 30+ years perfecting InP crystal growth. The photonics boom is creating demand that the entire industry cannot fulfill โ€” and AXT is one of the only companies positioned to supply it. As COHR and LITE ramp their 6-inch InP fabs, they need more InP substrates. AXTI is the upstream supplier they cannot replace quickly.

The Risk: AXTI is a ~$300M market cap company with lumpy revenue and significant customer concentration. It is not profitable on a consistent basis. If the photonics buildout slows or COHR/LITE internalize more substrate production, AXTI loses its leverage. This is a speculative position โ€” size it as 1โ€“2% of portfolio maximum.

Looking for the Next 800% Tech Stock Winner?

A peek inside the AI datacenter optical interconnect revolution

"As AI models grew exponentially, datacenters were hitting a critical bottleneck. They needed to move massive amounts of data between servers and switches, but the infrastructure couldn't keep up. That's where Credo came in โ€” and that's where optical is going next."

McHugh maps the three-stage evolution of AI datacenter connectivity: copper (CRDO, done โ€” 800%+ gains), optical interconnects (LITE, COHR, CIEN, ALAB, CLS, GLW โ€” running now), and co-packaged optics / silicon photonics (POET, LWLG โ€” speculative next frontier). His key warning: the optical plays are largely priced in after massive runs. The best risk/reward is ALAB, down 29% YTD despite 115% revenue growth. COHR is the best-valued optical name with a direct Nvidia partnership. POET and LWLG are high-risk binary bets on next-gen photonic integration.

The Photonics Boom: A Simple Guide to the Biggest Investment Theme in 2026

Yiannis Zourmpanos ยท YIAZOU ยท Mar 3, 2026

"The question is no longer whether optical interconnects will dominate data center architectures, but how quickly the ecosystem can mature."

Big Tech is committing $660โ€“690B to AI infrastructure in 2026 โ€” nearly double 2025. The AI cluster optics market alone hits $26B in 2026 (+60% YoY). The key insight: downstream transceiver makers (LITE at 202x P/E, COHR at 251x) are already priced in. The real opportunity is the upstream supply chain โ€” Indium Phosphide (InP) substrate makers, MOCVD equipment, and testing companies that most investors donโ€™t know exist. A 70% supply gap in InP with orders booked through 2026 and 18โ€“24 month equipment lead times creates a structural bottleneck. Co-packaged optics (CPO) deployment in 2028โ€“2030 extends the boom into the next decade.

Layer 1Raw Substratesโ€” The atoms everything is built from

Indium Phosphide (InP) and Silicon-on-Insulator (SOI) wafers are the raw materials that laser chips and silicon photonics chips are grown on. These materials cannot be made in standard silicon fabs โ€” they require decades of specialized expertise and equipment with 18โ€“24 month lead times. The supply gap is 70%+ and growing.

Layer 2IDM Laser Makersโ€” Own the laser IP and the fab โ€” the highest-moat layer

Integrated Device Manufacturers (IDMs) that both design and manufacture InP laser chips in their own fabs. This is the layer where "value creation is migrating" โ€” companies that own both the laser IP and the fab have a moat that takes 5+ years to replicate. Coherent's 6-inch InP fab gives it a 4x cost advantage over competitors on 2-inch wafers.

COHR~$15B

Layer 3Transceiver Assemblers & Connectivityโ€” Turn laser components into datacenter-ready modules

Companies that assemble transceivers from laser components, or make the connectivity chips that route data between transceivers. This layer is growing fast but faces more competition than the IDM layer. Margins are lower, but the TAM is enormous โ€” the $26B AI cluster optics market is primarily served by this tier.

Layer 4Passive Infrastructureโ€” The toll roads โ€” durable, lower upside, almost no downside

Passive infrastructure companies make the glass fiber, cables, and connectors that carry light signals. They do not make lasers or chips โ€” they make the pipes. Lower margins, lower risk, lower reward.

Gen 2CW + SiPhoโ€” Continuous Wave Laser + Silicon PhotonicsEMERGING โ€” Ramping 2026โ€“2027

Instead of an integrated EML chip, a continuous-wave (CW) laser provides a steady light source, and a separate silicon photonics chip handles the modulation. This decouples the laser from the modulator โ€” allowing silicon fabs (TSMC, Intel Foundry) to manufacture the modulator at scale, while the CW laser is sourced separately. The EML shortage is directly accelerating this transition as hyperscalers seek supply chain diversification.

Signal Path

The optical engine is co-packaged directly on the switch ASIC package โ€” eliminating the pluggable transceiver entirely. Light never has to travel through a connector. An External Laser Source (ELS) module provides CW light to the co-packaged engine. This eliminates ~30% of power consumption vs. pluggable optics. Jensen Huang confirmed at GTC 2026 (March 17) that CPO revenue ramp is 2027โ€“2028, not 2026. Coherent demonstrated a 6.4T socketed CPO at OFC 2026 (March 17โ€“19, LA).

Strategic Takeaway

The EML shortage is a double-edged catalyst

Near-term (2025โ€“2026): Extremely bullish for LITE and COHR โ€” they make EMLs and demand exceeds supply. But the shortage is also the forcing function accelerating the Gen 2 transition โ€” hyperscalers do not want to be held hostage to InP fab capacity, so they are funding CW+SiPho alternatives aggressively. COHR is the most durable long-term position because it is the only company demonstrating products across Gen 1, Gen 2, and Gen 3 simultaneously at OFC 2026 right now. SMTC is a 2027 story that got priced as a 2026 story โ€” the thesis is intact, the timeline is longer. AXTI has a structural headwind if Gen 2/3 adoption accelerates beyond InP substrates.

The Fourth Piece Ships

NVIDIA's Groq 3 LPX changes the inference business model โ€” and the investment thesis for every name on this watchlist.

The Four-Piece Convergence Thesis

BEP Research's thesis: NVIDIA's AI infrastructure platform has four convergent pieces. The first three โ€” stacked memory (HBM), backside power delivery, and the compiler (CUDA/Dynamo) โ€” were already in place. The fourth piece โ€” optically-synchronized dataflow inference โ€” shipped at GTC 2026 as the Groq 3 LPX.

Groq 3 LPX โ€” SHIPS Q3 2026
โšก JUST ANNOUNCED

The Thresher vs. The Speed Demon

AI inference has two fundamentally different phases. The GPU dominates one. The LPU owns the other. NVIDIA now sells both.

Vera Rubin NVL72 โ€” The Thresher
Prefill Phase

Processing the input prompt. Compute-intensive, parallelizable, HBM-memory-bound. GPUs excel here. Handles training, prefill, and high-concurrency batch inference.

Memory: HBM4 ยท Architecture: GPU ยท Workload: Batch
Groq 3 LPX โ€” The Speed Demon
Decode Phase

Generating tokens one by one. Memory-bandwidth-bound, latency-sensitive, sequential. LPUs with 500MB on-chip SRAM per chip are dramatically better. 256 LP30 chips per rack, 640 TB/s scale-up bandwidth.

Memory: SRAM ยท Architecture: LPU ยท Workload: Interactive

The Revenue Tier Model โ€” Jensen's Slide That Changes Everything

NVIDIA's keynote slide showed that pairing LPX racks with NVL72 racks unlocks dramatically higher revenue per megawatt. This is not a replacement cycle โ€” it is an additive revenue layer. Jensen said ~25% of every AI cluster should be LPX-type inference hardware.

Portfolio Implications โ€” How LPX Changes Each Name

NVDA
DIRECTLY BULLISH

The street still models NVIDIA primarily as a training hardware company. LPX changes the revenue model: NVIDIA now sells a GPU rack for training/prefill AND an LPU rack for decode. The combination unlocks 10x more revenue per megawatt for hyperscalers. This is additive revenue, not a replacement cycle. The $20B Groq acquihire is already looking cheap.

COHR
STRUCTURALLY BULLISH

If 25% of every AI cluster is LPX-type inference hardware, and LPX racks communicate optically at 640 TB/s, the optical transceiver and CPO market just got a structural demand uplift. The article's title references 'optically-synchronized dataflow inference' โ€” the LPX architecture is exactly the system CPO was designed for. COHR's OFC 2026 CPO demonstration is directly relevant.

TSEM
QUIETLY BULLISH

The optical interconnect fabric tying 256 LPUs together at 640 TB/s requires silicon photonics. Tower's PH18 platform is the leading open-foundry SiPho process. This is a direct demand driver for TSEM that the market has not fully priced. The LPX architecture is a proof-of-concept for exactly the kind of rack-scale optical interconnect Tower is building capacity to serve.

ALAB
MOST UNDERAPPRECIATED

Astera Labs makes the PCIe/CXL connectivity fabric that connects LPX racks to NVL72 racks and to the host CPU. In a heterogeneous inference architecture with GPU racks and LPU racks working together, the connectivity fabric between them becomes critical infrastructure. ALAB is the toll road. This is the strongest argument yet for ALAB's valuation โ€” currently 51% off its 52-week high.

MU
NUANCED โ€” WATCH WEDNESDAY

The LPU uses SRAM, not HBM. The Groq architecture was specifically designed to avoid HBM because HBM has too much latency for decode-phase inference. If 25% of AI cluster compute shifts to LPX-type SRAM architectures, that is 25% of the compute budget that does not buy HBM. Mild headwind at the margin โ€” not a thesis-killer, since NVL72 still uses massive HBM4. But worth noting going into Wednesday's earnings (Mar 19).

LITE
STRUCTURALLY BULLISH

Same optical demand uplift as COHR. LPX rack-scale optical interconnect at 640 TB/s is exactly the kind of system that drives 800G and 1.6T transceiver demand. The CPO 'headwind' narrative for LITE is backwards โ€” CPO is the enabling technology for the LPX architecture to work at scale. LITE's EML lasers feed the CW+SiPho engines that power Gen 2 and Gen 3 optical interconnects.

โš  Key Risk โ€” The One Thing the Bull Case Requires

The LPX ships in Q3 2026 โ€” Jensen said "very likely Q3." That is 6 months away. Samsung has to manufacture 256-chip racks at scale, the optical interconnect fabric has to work at 640 TB/s, and the Dynamo inference software stack has to orchestrate the whole thing. NVIDIA has never shipped a product like this before. The probability of a delay is non-trivial. The market will price this in before it ships โ€” but execution risk is real. Watch for any Q3 2026 guidance language in upcoming earnings calls from NVDA, MU, and ALAB.

Investment Framework ยท Vernor Vinge (1993) ร— Jason's Chips (2026)

Why This Cycle Is Different

Three principles for investing in the age of AI โ€” derived from a 1993 paper that predicted almost everything about today's AI boom, and why the dot-com analogy collapses under scrutiny.

1993
PREDICTED
"An ultraintelligent machine will be built and that it will be the last invention that man need make."

โ€” Vernor Vinge, The Coming Technological Singularity (1993)

Written when the internet had barely begun ยท 33 years before GPT-4 ยท Accurate within the predicted window

Analysis based on: Jason's Chips ยท "How a 1993 Paper Predicted the AI Boom" ยท Apr 4, 2026

Vernor Vinge predicted human-level AI before 2030 in 1993 โ€” not because he could picture an NVL72 rack or EUV lithography, but because he could follow Moore's Law to its logical conclusion. The mechanism was simple: compute keeps improving, and intelligence is downstream of compute.

The dot-com bear case argues that AI infrastructure will follow the telecom playbook: massive buildout, overcapacity, collapse. But that analogy breaks on a fundamental asymmetry. The telecom buildout was a one-time capacity installation. Once the fiber was laid, it was laid. AI infrastructure is the opposite.

GPT-3 training: ~3.6ร—10ยฒยณ FLOPs
GPT-4 training: ~10ร— more than GPT-3
Next frontier model: another step up
Each smarter model unlocks new use cases โ†’ demands even smarter models โ†’ demands more compute

The demand curve for AI compute has no ceiling anyone can credibly forecast. This is not a cycle. It is a structural shift in what the global economy needs from semiconductors.

Portfolio Positioning
NVDAGPU compute โ€” the staircase engine
TSMLeading-edge fab โ€” every step requires TSMC
MUHBM memory โ€” scales with each model generation
ASMLEUV tools โ€” enables the transistor shrinkage that powers Moore's Law

โš  KEY RISK NOT IN THE ARTICLE: The staircase demand curve assumes scaling laws hold โ€” that each new frontier model requires meaningfully more compute than the last. If scaling laws break down before AGI (capability plateau), the demand curve flattens and the infrastructure thesis weakens. Additionally, ASML and TSMC face geopolitical concentration risk that the "atoms beat bits" framing amplifies rather than reduces. These risks do not invalidate the thesis but must be sized accordingly.

Defense primes are not cheap โ€” they trade at 16โ€“21x forward earnings, reflecting already-elevated expectations for budget growth. A rapid ceasefire or diplomatic resolution could cause a short-term pullback.
