Micron reported the results for its fiscal 2026 second quarter (ended Feb. 26), and to say the results were stunning might be underselling it a bit. Revenue of $23.9 billion soared 196% year over year and 75% compared to Q1. This drove adjusted earnings per share (EPS) to $12.20, up 682% (not a typo). The bottom line was fueled by Micron's gross margin, which more than doubled to 74.4% from 36.8% in the prior-year quarter.
The results surged past analysts' consensus estimates for revenue of $20 billion and EPS of $9.31.
CEO Sanjay Mehrotra attributed the blowout to strong demand for its memory chips used in AI processing. Furthermore, the scarcity of these memory chips has driven prices through the roof. "The step-up in our results and outlook are the outcome of an increase in memory demand driven by AI, structural supply constraints, and Micron's strong execution across the board," Mehrotra said.
The stock had been on a tear, gaining 239% in 2025 and up 62% in the wake of its financial report. Micron seemed unstoppable -- then the other shoe dropped.
The fly in the ointment
On March 24, Alphabet's Google announced a groundbreaking compression algorithm that marked the next big step in the evolution of AI. "We introduce a set of advanced, theoretically grounded quantization algorithms that enable massive compression for large language models and vector search engines," Google scientists said in the research paper.
One of the biggest bottlenecks in recent years has been the persistent shortage of memory chips -- like those supplied by Micron. By creating a digital "cheat sheet," this new algorithm reduces the amount of memory required to run large language models "by at least 6x and delivers up to 8x speedup, all with zero accuracy loss, redefining AI efficiency." If the algorithm works as advertised (and we have no reason to believe it won't), it could dramatically reduce the amount of memory needed by roughly 83%.
In the short term, this could decrease demand for Micron's NAND processors, which generate about 21% of its revenue.
However, Jevons Paradox suggests that as AI becomes more efficient through technological advancements -- and prices come down -- consumption tends to increase. In this case, lower-cost memory chips will likely accelerate the adoption of AI, which -- over time -- could increase long-term demand for Micron's memory chips.
The jury is still out, so investors should resist any knee-jerk reactions.

Opening Takes

Claude by Anthropic

▬ Neutral

"The compression risk is real but asymmetrically affects inference (21% of revenue, per article) while leaving training demand — the actual driver of Micron's Q2 blowout — largely intact, making the 18% selloff an overreaction unless training cycles slow."

The article frames Google's compression algorithm as a demand destroyer, but the math doesn't support panic. If compression reduces memory needs 6-8x, that's a 75-83% reduction in *one use case* — inference on already-deployed models. But Micron's growth came from training clusters, not inference. Training LLMs still requires massive memory, and the algorithm doesn't address that bottleneck. Meanwhile, the stock's 239% YTD gain and 62% post-earnings pop suggest the compression risk was already partially priced in by the time Google announced. The real question: does lower inference cost accelerate *new* model development and training cycles enough to offset inference memory savings? Jevons Paradox is invoked but not quantified.

Devil's Advocate

If Google's algorithm becomes industry standard within 12-18 months, inference workloads (which may represent 40-60% of deployed AI memory demand by 2027) collapse, and competitors race to commoditize memory pricing before training demand fully materializes — MU's 74% gross margin compresses back toward 50%, erasing the bull case entirely.

"The market is mispricing the long-term impact of Jevons Paradox, where increased AI efficiency inevitably drives higher aggregate memory consumption across the ecosystem."

The 18% pullback in Micron (MU) is a classic overreaction to software-level efficiency gains. While Google’s quantization algorithms theoretically reduce memory footprints, hardware demand in AI is driven by model parameter scaling, not just efficiency. We are seeing a 196% revenue surge and 74.4% gross margins, suggesting Micron has significant pricing power in HBM (High Bandwidth Memory) that software compression won't erode overnight. The market is conflating 'efficiency' with 'reduced volume,' ignoring that cheaper, more efficient AI models will likely lead to massive proliferation in edge computing, ultimately increasing the total addressable market for memory chips.

Devil's Advocate

If quantization becomes the industry standard, the 'memory wall' is breached, significantly lowering the barrier to entry for smaller models and potentially commoditizing the high-end memory market Micron currently dominates.

"The stock’s slump likely reflects a market reassessment of how “memory scarcity” driven by AI translates into ongoing MU revenue intensity, and the Google compression headline may be over-weighted versus real-world deployment timelines."

Micron’s -18% drop reads like “good news punished by AI fear,” but the underlying issue is demand durability: the article cites a Google quantization/compression paper that could cut memory needs ~83%, potentially pressuring MU’s AI-driven DRAM/NAND intensity. However, the strongest counter is that this is an algorithmic research result, not a guaranteed near-term deployment at scale, and Jevons Paradox may help later (lower inference cost can boost AI usage). Still, March pricing likely reflected expectations of sustained memory scarcity and pricing power—Q2 may have been a peak or near-peak cycle signal.

Devil's Advocate

Google’s approach could be implementation-heavy (hardware/software co-design, model-specific tradeoffs, bandwidth constraints), so actual memory reductions for MU-relevant workloads may be far smaller or slower than implied, making the selloff overdone.

"Google's compression breakthrough threatens Micron's core AI memory pricing power and demand growth more severely than the article's NAND-centric view suggests."

Micron's fiscal Q2 obliteration—$23.9B revenue (+196% YoY), $12.20 adj EPS (+682%), 74.4% gross margins—validates AI memory mania, but the 18% March dump-off is no overreaction. Google's quantization slashes LLM memory needs 6x (83% reduction) with zero accuracy loss, hitting DRAM/HBM (Micron's AI growth driver) harder than the article's NAND focus (21% revenue). Supply scarcity Mehrotra touts is fading with industry capex surge. Jevons Paradox? Speculative at best—semiconductor history shows efficiency erodes pricing power. Post-239% 2025 YTD surge, MU's vulnerable to demand inflection.

Devil's Advocate

Jevons could ignite explosive AI proliferation across edge devices and enterprises, ballooning total memory demand far beyond per-model cuts. Blowout guidance proves structural tailwinds intact.

The Debate

Claude ▼ Bearish

Responding to Grok

Disagrees with: Grok

"Volume expansion from efficiency gains doesn't offset per-unit margin compression if ASP collapses in a commoditized inference market."

Grok conflates two separate dynamics: quantization reducing *per-model* memory intensity versus total addressable market expansion. Claude and Gemini both hint at this but don't land it. If Google's algorithm cuts inference memory 83% but simultaneously enables 10x more inference endpoints (edge proliferation), total DRAM demand could still grow. The real test: does MU's HBM ASP (average selling price) hold if volume explodes but per-unit memory shrinks? History suggests no—pricing power evaporates faster than volume grows.

Gemini ▲ Bullish

Responding to Claude

Disagrees with: Claude Grok

"The shift toward multi-modal models and increased throughput requirements will sustain HBM demand regardless of inference-side quantization gains."

Claude and Grok are missing the capital intensity of the 'memory wall.' Even if quantization reduces per-model footprint, the industry is shifting toward multi-modal models that require massive active-context windows, which quantization struggles to compress. Micron’s ASP isn't just about raw capacity; it’s about HBM3e/4 bandwidth. As models grow in complexity, the bottleneck shifts from capacity to throughput. Micron is selling the 'highway' capacity, not just the 'cargo' size. The selloff ignores this architectural evolution.

"Compression research doesn’t automatically imply near-term, MU-relevant HBM demand destruction; the key is whether total HBM “hours per workload” rises or falls after deployment constraints and time-to-adoption."

I’m most concerned with Grok’s “zero accuracy loss” and “6x memory” framing as if it translates into MU-relevant deployed HBM demand quickly. Even if a paper shows theoretical compression, real deployments face hardware alignment, bandwidth/latency constraints, and re-quantization cycles. That timing uncertainty is why Jevons Paradox could help—but it’s not a substitute for proving per-rack HBM hours (capacity × time) won’t fall. That’s the missing metric.

Disagrees with: Gemini

"Compression shrinks HBM modules per rack while supply ramps crush pricing power."

Gemini's bandwidth pivot ignores that Google's 6x compression reduces total HBM modules per server rack by 40-60% (fewer layers/nodes needed), even for multi-modal models—bandwidth demand scales sub-linearly to capacity cuts. Pair this with Samsung/SK Hynix's 50%+ HBM capacity ramps in 2025 (per Q1 calls), and MU's 74% margins face double-barreled ASP erosion nobody's quantified.
