Micron Technology (MU) ranked as the third most-discussed ticker on Reddit on May 6 with a sentiment score of 0.42, driven by a surge in AI memory theses across r/wallstreetbets and r/ValueInvesting.
The broader semiconductor rally — including AMD jumping 16% and Super Micro Computer surging 22% on earnings — provided a strong tailwind for memory names like Micron and SanDisk.
Reddit users argued that Micron remains undervalued despite its massive run, citing a DCF fair value estimate of $586.77 and structural demand from AI data centers that changes the cyclical nature of memory.

Reddit's Bull Case: 'Memory Is No Longer Just a Commodity'
The most upvoted post of the day on r/wallstreetbets carried a confident headline: "MU Earnings: Turns out AI actually DOES need memory." The author, who claimed a position of 1,200 shares, argued that Micron beat expectations on its most recent earnings, that HBM demand was "crazy," and that margins were expanding. Many commenters agreed that sector rotation into semiconductors and memory was accelerating.
A second, longer r/wallstreetbets post laid out a detailed thesis: "DD: Why Micron and Memory is Still an Undervalued Play in the AI Supercycle." The author argued that the "cyclical" label is outdated. With a consolidated market of few producers and hyperscalers like Google, Meta, and Microsoft spending billions on data centers, memory pricing has found a structural floor. The post cited severe memory shortages benefiting ![]()
On r/ValueInvesting, a user posted, "My value algorithm flagged Micron as the #1 value pick in the S&P 500 on April 1st. I thought it was a bug." The algorithm gave the stock a DCF margin-of-safety score of 20 out of 20, with a fair value estimate of $586.77 against a price of $337.84. Another user in the same community mused about Intel, AMD, and Micron one day surpassing Berkshire Hathaway in market cap — a reflection of how far sentiment has swung since Intel's near-bankruptcy narrative.

The VanEck Semiconductor ETF (SMH) gained 30% in the past month alone. Meanwhile, a Benzinga report noted that SanDisk secured over $42 billion in long-term AI supply agreements, reinforcing the idea that memory demand is now driven by structural contracts rather than spot-market volatility.
Even Michael Burry's high-profile short on the semiconductor ETF SOXX came under pressure, with the fund trading 60% above its 200-day moving average — a record stretch. Some Reddit commenters interpreted this as a contrarian bullish signal for the sector.
The Narrative Shift: From Cyclical to Structural Growth

Another user on r/wallstreetbets summed it up succinctly: "MU is just heating up." The author cited "inefficient market pricing" that ignored AI data center buildouts, capex increases, and severe memory shortages — all of which he argued benefit Micron disproportionately.
