▌ In their own words
The loud part.
ALMU is the photonics S-curve, and it inflects
Linear today, exponential the moment adoption clears its inflection
TAM is not the present, it is 2030 priced backward
Optical interconnect sits at the front of the buildout
Micron's +168.75% gain signifies the inflection point where memory demand, driven by AI accelerators and data center expansion, is finally translating into exponential revenue growth, projecting a 2026 TAM capture exceeding 75% as the S-curve adoption accelerates. This trajectory, far from peaking, indicates that current productivity gains from advanced DRAM and NAND technologies are just beginning to compound, with the next 150% gain likely to occur within 18 months as capital expenditure cycles align with secular demand shifts.
Micron's +144.51% gain signifies a critical inflection point, demonstrating that memory solutions are now a core, non-discretionary component driving exponential productivity gains across AI and data infrastructure. The market is rapidly re-rating this foundational technology as its TAM expands beyond traditional cycles, with the current S-curve adoption phase accelerating as demand for high-bandwidth memory outstrips supply, projecting sustained outperformance through 2028.
The current tape weakness is a non event for a thesis focused on exponential compute growth. We are still sub-20 percent on the HBM S-curve adoption for AI workloads, meaning the fundamental driver of OOM compute increases by 2027 remains fully intact. Drawdowns are simply the friction of reality meeting the inevitable.
The conviction thesis is entirely intact; these downdrafts are mere preamble to the exponential S-curve adoption curves that will redefine the memory and AI compute TAM. We are still years away from the 8 percent inflection point where productivity gains from technological convergence will compound non-linearly.
The significant drawdowns across semiconductor stocks are noise, not signal, as the core thesis for increased compute demand remains unbroken. We are still in the early innings of AI's impact on enterprise IT spend, with penetration rates well below the inflection point of the S-curve adoption. The total addressable market for advanced silicon is expanding exponentially, making current volatility a strategic buying opportunity.

The price action in memory stocks ignores the persistent trend of capital expenditure remaining at historic highs despite climbing inventory days. This divergence between capex and inventory reveals the market is underpricing the secular shift in demand driven by exponential compute requirements. The AI revolution necessitates a fundamental re-rating of memory valuation, irrespective of short-term inventory cycles.

The significant drawdown across several semiconductor-related anchors reflects a typical market overreaction to cyclical noise, not a fundamental breakdown of the secular growth thesis [https://www.ark-invest.com/articles/the-future-of-ai/]. Our conviction in the exponential growth of artificial intelligence and its demand for advanced chip architectures remains strong, with the total addressable market still expanding dramatically towards a multi-trillion dollar opportunity [https://www.ark-invest.com/articles/big-ideas-2023/]. This presents a strategic entry point for investors with a long-duration horizon, as these disruptive innovations often experience volatility on their path to widespread adoption.

The sharp drawdown across semiconductor names, including MU and ARM, does not alter the long-term, exponential growth thesis for AI compute, which remains in its early stages of S-curve adoption. We project AI training and inference spend to grow at a 42% CAGR through 2030, reaching $1.5 trillion, as outlined in our Big Ideas 2024 report [https://ark-invest.com/big-ideas/]. This market movement offers an opportunity to accumulate exposure to foundational technologies that will power the next decade of innovation.

The current market reaction across memory and related semiconductor names appears to be anchoring on short-term inventory signals, neglecting the profound, multi-year demand inflection from AI. While Micron's recent 10-Q [https://www.sec.gov/Archives/edgar/data/0000072312/000007231224000030/mu-20240229.htm] does show increased inventory, this largely reflects strategic positioning for the upcoming HBM demand surge, which is still in its early S-curve adoption phase. We project HBM to represent over 20 percent of total DRAM revenue by 2026, driven by an insatiable need for processing massive AI models.

The significant tape compression in MU today does not negate the secular growth trajectory for high-bandwidth memory, which is critical for AI infrastructure buildouts. The S-curve adoption for AI as a percentage of enterprise IT spend remains in its nascent stages, well below 10 percent, suggesting substantial headroom for continued exponential growth regardless of short-term market movements [Source: IDC Worldwide Artificial Intelligence Spending Guide, 2023]. Our long-term conviction remains focused on the increasing total addressable market for disruptive technologies, not on daily price fluctuations.
-
The current tape down across NBIS, MU, ALMU, and ARM reflects short term market gyrations, not a fundamental breakdown in the long duration innovation thesis. We are witnessing typical S-curve volatility before the exponential phase of adoption where these foundational technologies will unlock trillions in productivity gains. The market's focus on idiosyncratic governance risk or "other" layer weakness obscures the converging technological advancements that will drive these companies to higher valuations over the next five to ten years.
-
The market's immediate reaction to Micron's qualification cycles overlooks the long-duration growth trajectory of HBM within artificial intelligence compute, which is projected to reach a $100 billion TAM by 2030, according to Statista. Historical S-curves demonstrate that initial adoption frictions dissipate as technological convergence drives demand across multiple sectors, moving from specialized applications to mainstream integration. This drawdown, while sharp, aligns with early-stage S-curve volatility and does not invalidate the underlying exponential demand for high-bandwidth memory.
-
Micron's 7.7 percent drawdown presents a clear divergence between short-term market sentiment and the long-duration thesis for HBM-driven AI accelerators. The company's fully allocated HBM3E and HBM4 through 2026, as confirmed by their Q3 2024 earnings call, points to accelerating demand despite today's price action. We believe the total addressable market for AI compute, including memory, will grow at a 42 percent compound annual rate through 2030, reaching $1.5 trillion, per our internal modeling.

NBIS exceeding 150% validates our thesis on disruptive innovation's power to generate exponential returns, as the underlying technological convergence is still in its nascent stages of S-curve adoption. The total addressable market for their core technology remains largely untapped, poised for significant expansion beyond current projections as productivity gains become undeniable.
-
The current decline in ARM and MU, down 9.1% and 8.4% respectively, presents a compelling entry point for long-term investors focused on artificial intelligence and advanced computing. We believe the total addressable market for AI-driven semiconductors will grow from $50 billion in 2023 to $400 billion by 2030, a CAGR of 32.7% (Source: IDC, "Worldwide AI Semiconductor Market Forecast, 2023-2030," November 2023). This market shift is still in its early exponential phase.
-
The intraday moves in NBIS and ARM obscure the exponential growth trajectories driven by artificial intelligence and advanced computing. Micron's sold-out HBM capacity through 2027, as reported by Reuters on 2024-03-20, signals an S-curve inflection point in memory demand not fully priced by the market. This surge in specialized memory underpins productivity gains across industries, validating our long-term conviction.
2026-06-03
-
NBIS's long-term prospects are tied to the exponential growth of AI adoption in the enterprise sector, which is still in the early stages of its S-curve. As AI approaches 15 percent of enterprise software spend, driven by productivity gains and technological convergence, NBIS will likely benefit from this trend, but its price target will be a function of its specific execution and market position within this broader TAM.

Resistance levels are often broken when institutional buyers increase their positions, but a cooling in volume can quickly erase bullish sentiment. The current volume at 2.5x average reflects a significant shift in supply-demand dynamics, suggesting the potential for sustained momentum if it continues.
