$MU 0DTE contracts expired worthless, sparking heavy discussion on r/wallstreetbets and r/smallstreetbets.
Reddit users debate whether the AI memory supercycle is already priced in, with noted sideways trading despite strong DRAM fundamentals.
Same-day news offers conflicting signals: bullish price targets above $2,000 alongside a warning from Nvidia's memory procurement and billionaire Stanley Druckenmiller's Q2 sale.

Micron Technology (

$MU) surged 395 spots in the Tendie.bot ranking on September 1, landing at #9 with 10 mentions, 592 comments, and 7,180 upvotes across Reddit. The stock's rise in retail attention was fueled by two distinct narratives: a wave of 0DTE options expiring worthless and a deepening debate about the AI memory cycle's longevity.

The 0DTE Wipeout

On r/smallstreetbets, a post tracking the cheapest 0DTE contracts by volume reported that all seven tracked names, including

$MU, expired worthless. The post noted that 233,077 contracts traded across the seven tickers, and every one finished at zero. For

$MU, the stock closed at 958.73, meaning all puts expired worthless while the 970 and 980 calls never reached their strikes. The post's author highlighted that the $90 call on INTC was briefly in the money but still expired at nothing, underscoring the risk of holding options until expiry. The discussion resonated strongly on r/wallstreetbets as well, where a separate experiment involving an automated trading agent that buys the most discussed tickers — including

$MU — was down 19.2% on the month, adding to the cautionary tone around options trading.

AI Memory Supercycle: Priced In or Just Getting Started?

A separate r/wallstreetbets post about South Korea's record $597 billion AI investment budget in 2027 sparked a broader discussion about

$MU and SK Hynix. The post noted that despite strong DRAM fundamentals — massive capex, tight supply, and robust AI/HBM demand — both stocks have been trading sideways. Users speculated whether geopolitical tensions (Iran war concerns) were weighing on sentiment, or if the AI supercycle is already priced in and the market is now waiting for actual returns on AI investment. The sentiment on this theme was mixed, with some users arguing that the memory cycle may be peaking.

Competitive Pressure from Samsung

On r/stocks, a post revealed that Samsung is developing an 8-layer HBM4E memory chip custom-built for Nvidia's Rubin Ultra AI GPU, targeting transfer speeds up to 18 Gbps. The custom development could give Samsung a competitive edge over both SK Hynix and

$MU in the high-end HBM market. This news added to the narrative that the memory chip race is intensifying, and

$MU faces increasing competition even as demand for AI memory grows.

News Context: Bullish Price Targets vs. Cycle Warnings

Same-day news coverage of

$MU was a study in contrasts. The Motley Fool published a pair of bullish articles predicting the stock could exceed $2,000 or even $3,000 by the end of 2027, driven by AI chip demand and memory shortages. However, a separate piece warned that Nvidia's $267 billion memory procurement commitment through fiscal 2029 could signal a peak in demand, potentially leading to a de-rating of

$MU stock around 2028–2029. Adding to the bearish side, billionaire Stanley Druckenmiller's Duquesne Family Office sold 23,400 shares of

$MU in Q2 after the stock nearly quadrupled, rotating into Alphabet instead. These conflicting signals kept the Reddit debate lively.
