Nvidia was the top ticker on Tendie.bot on September 24, propelled by a surge in Reddit discussion across multiple investing communities. Users tallied 14 posts and nearly 1,000 comments about

$NVDA on the day, with overall sentiment leaning bullish at a score of 0.59. The conversation centered on the scale of AI infrastructure investments and whether the spending frenzy can be sustained.

Reddit draws parallels to the dot-com era

The most popular post of the day on r/stockmarket drew a direct comparison between the current AI buildout and the dot-com bubble. The user highlighted "circular spending" between companies like

$NVDA,

$AMD,

$MSFT, and

$META, calling LLMs and GPUs the "current equivalent of domain names and MOUs for ad dollars."

Still, the same user acknowledged that

$NVDA occupies a unique position as the "shovel seller" — the company providing the essential hardware that every AI player needs. A separate post on r/stockmarket covering the $500 billion Stargate project from

$ORCL,

$OPENAI, and

$SOFT echoed this sentiment. The OP questioned why companies keep announcing ever-larger data center plans without showing profits from AI, adding: "Save for Nvidia, which is the shovel-seller in the California gold rush."

Micron earnings reinforce Nvidia's role in AI hardware

On r/stocks,

$MU earnings became a proxy for discussing

$NVDA demand. Micron reported fiscal Q4 results that beat estimates, with revenue up 46% year over year. The company makes high-bandwidth memory (HBM) used in Nvidia's Blackwell GPUs, and several commenters pointed to this as evidence that AI chip demand remains robust.

"High-end AI chips such as those made by Nvidia require increasing amounts of high-tech memory called high-bandwidth memory, which Micron makes," one user summarized, citing the

$CNBC article shared in the thread. Micron shares have nearly doubled in 2025.

Small caps and microcaps try to ride Nvidia's coattails

Several lower-traffic posts on r/pennystocks and r/wallstreetbets discussed companies positioning themselves alongside

$NVDA.

$NVTS (Navitas Semiconductor) was highlighted for its gallium nitride power semiconductors used in AI data centers, with a user noting the company is "eyeing revival through NVIDIA AI synergies." Meanwhile,

$NVNI announced a new NuviniAI Index that explicitly mentions

$NVDA as part of its ecosystem.

These fringe discussions underscore a broader pattern: even when traders chase smaller names,

$NVDA remains the gravitational center of the AI infrastructure narrative.

Sentiment breakdown

Sentiment: 59% bullish, 25% bearish, 16% neutral.

Across the three largest communities discussing

$NVDA, sentiment was strongest on r/wallstreetbets (0.65 average) and most skeptical on r/stockmarket (0.39 average). The r/stocks community landed in the middle at 0.52, reflecting a cautious but generally optimistic view of Nvidia's prospects.
