Top Reddit Stocks Last Week: MRNA, GOOG, and NVDA

By AltIndex Research · 3 min read · August 24, 7:46 am

Reddit attention last week was split between the usual mega-cap magnets and one clear breakout story. By total mentions, Moderna, Google, and NVIDIA led the pack. But the biggest change was easy to spot: Moderna went from barely discussed to one of the hottest tickers on the platform after a trial update sent the stock sharply higher.

Moderna Was the Week’s Real Shockwave

Moderna was the standout by a mile. Mentions jumped to 2,997 from just 8 the week before, while the stock more than doubled. The catalyst was clear across Reddit’s top posts: late-stage trial results for Moderna and Merck’s cancer vaccine, with posts highlighting promise in preventing melanoma recurrence.

What followed was classic Reddit behavior. The news quickly turned into screenshots of overnight call gains, huge percentage wins, and fast options trades on both sides. That matters because it shows the story was not just about biotech optimism. It became a volatility event, which helped pull in even more attention. Sentiment stayed neutral overall, but the tone of the top posts showed excitement and disbelief more than caution.

NVIDIA Stayed Loud Ahead of Earnings

NVIDIA remained one of Reddit’s biggest names, with 2,627 mentions, up 26.54% week over week, even as the stock fell 6.79%. The main narratives were straightforward: a post about NVIDIA providing up to $105 billion in guarantees for OpenAI’s Ohio data center, and another round of discussion around AI-related price hikes of more than 15% ahead of earnings.

That mix kept the stock in the spotlight. On one side, Reddit read the pricing story as a sign of demand and pricing power. On the other, users questioned whether higher chip costs could pressure customers and hyperscalers. The result was heavy attention with a neutral tone, which fits a stock that is still central to the AI trade but heading into a major event with plenty of debate.

Google Was Big by Volume, Not by Change

Google was still a top mention leader at 2,795 posts, but its attention actually slipped 6.58% from the prior week and the stock was nearly flat. That makes it different from Moderna and NVIDIA. Google was present, but it was not the freshest story on Reddit.

The top-post mix shows why. The clearest stock-specific catalyst was chatter around Marvell’s AI chip deal that lets Google buy up to $12.2 billion in shares. Beyond that, Google showed up inside broader market threads rather than through one dominant company-specific event. Sentiment was bullish, but this looked more like steady background attention than a breakout move.

The clean read from Reddit last week is this: Moderna was the breakout mover, NVIDIA was the biggest AI battleground, and Google remained a heavyweight without becoming a new momentum story. For retail investors, that distinction matters. The biggest names still draw traffic, but the sharpest shifts in attention usually come from a fresh catalyst, and last week that was clearly MRNA.
