Billionaire Philippe Laffont Just Bought Micron Stock in Q2: Is the Artificial Intelligence (AI) Memory Winner a Buy for 2026?

Micron stock is up ~225% in 2026 but is still down >20% from its June all-time high, as the article argues the memory-chip shortage remains supportive. Revenue surged 346% YoY in fiscal 2026 Q3 (ended May 28), with Wall Street expecting 348% growth in fiscal Q4, while management projects tightness won’t ease until 2028 at the earliest. Despite the profit tailwind and memory prices rising on AI-driven demand, the stock trades at ~6x fiscal 2027 earnings versus a suggested ~20x ‘market-average’ valuation, implying upside if the cyclicality worry fades.

Analysis

The market mechanism here is scarcity rent, not just “AI demand.” When memory is fully allocated, the supplier with the cleanest mix and best yield curve captures disproportionate incremental margin, while OEMs and server assemblers absorb the volatility in bill-of-materials costs. That makes MU the direct beneficiary, but it also raises a second-order squeeze on names with high memory intensity such as DELL/HPE and, to a lesser extent, handset and PC supply chains where pricing power is weaker.

Near term, the main catalyst is not capacity itself but evidence that contract pricing stays elevated through the next earnings cycle. The risk is that consensus extrapolates peak pricing too linearly: semis can look cheap on forward P/E right before the market starts discounting normalization, especially if peers accelerate capex or if customers begin inventory digestion. The thesis breaks if sequential ASPs flatten, backlog shortens, or management sounds more cautious on margin expansion over the next 1-3 quarters.

Contrarian view: the crowd may be too focused on the headline “shortage” and not enough on duration. If AI memory allocation remains tight into 2027, MU’s earnings power can stay underappreciated longer than investors expect; but if the shortage is simply bringing forward demand and not expanding the end market, this is still a cyclical stock with a trapdoor multiple. The right lens is whether normalized earnings are being revised up, not whether current earnings look optically cheap.

Key Decisions for Investors

• Stay constructive on MU, but only add on pullbacks or post-earnings volatility; use a 6-12 month call spread rather than outright stock if you want upside with defined carry risk.
• Pair trade: long MU / short DELL over the next 1-3 quarters to express memory pricing power versus OEM margin compression from rising component costs.
• If you already own MU, hedge part of the position with a broad semiconductor ETF short or put spread into the next guide, since any sign of normalization can compress the multiple fast.
• Set a thesis alert on MU gross margin and sequential pricing commentary: if margins stop expanding or management signals easing tightness before mid-2027, reduce exposure immediately.
