SpaceX, GameStop, Palantir and More: 5 Stocks Investors Couldn't Stop Buzzing About This Week

Retail investors talked up five hot stocks during the week (Aug.

3 to Aug.

7) on X and Reddit’s r/WallStreetBets, driven by retail hype, earnings, AI infrastructure momentum, and corporate news flow.

Space Exploration Technologies Corp. (NASDAQ: SPCX ), Advanced Micro Devices Inc. (NASDAQ: AMD ), Palantir Technologies Inc. (NASDAQ: PLTR ), GameStop Corp. (NYSE: GME ), and Hertz Global Holdings Inc. (NASDAQ: HTZ ), spanning space, AI, semiconductors, cloud, cybersecurity, gaming, and car rental, reflected strong retail interest.

Space Exploration Technologies SPCX this week centered on its first public second-quarter 2026 earnings, which showed $7.8 billion in revenue, up 92% year-over-year; an improved net loss of $541 million; strong Starlink growth; AI segment expansion; and a $47.5 billion backlog, though heavy AI-related capex of around $16 billion plus sparked investor concern.

The stock then recovered some ground on Aug.

6 amid high volume as a major lockup expired, releasing up to ~911 million insider shares.

Some bullish retail investors were mocking SPCX bears for expecting a decline in the stock after its first tranche of lockup expiration.

Also, it was 28.36% lower over the last month and up 2.42% in the last five trading sessions, as of the publication of this article.

According to Edge Stock Rankings, SPCX was maintaining a weak price trend over the short, medium, and long terms.

Advanced Micro Devices AMD’s major news this week centered on its second-quarter 2026 earnings, which showed record revenue of $11.54 billion, up 50% YoY, and adjusted EPS of $1.66, driven by Data Center sales more than doubling to $6.7 billion on strong EPYC CPU and Instinct GPU demand.

The company guided third-quarter revenue to about $13 billion and said Data Center revenue should more than double again in 2027.

On Aug.

6, AMD announced it would acquire Taalas to strengthen its AI inference capabilities.

Some retail traders believed that AMD’s acquisition of Taalas gives AMD its own hyper-efficient inference chip tech, making its partnership with Cerebras Systems Inc. (NASDAQ: CBRS ) redundant and destroying the value of CBRS stock.

The company raised full-year 2026 revenue guidance to $8.15—$8.16 billion, from prior ~$7.65—$7.66 billion, along with higher outlooks for operating income and free cash flow, citing surging demand for "sovereign AI." Despite its “otherworldly” earnings, some retail investors were still skeptical of PLTR’s performance.

GameStop GME’s main news this week was its Aug.

3 announcement of a private exchange of about $1.4 billion in outstanding 0% convertible senior notes due 2030 and 2032 for Class A common stock.

This will retire its debt without using cash.

The deal is expected to close around Sept.

23, with the share count based partly on a 35-day VWAP starting that day.

The move sparked dilution concerns and sent the stock down sharply, wiping out its 2026 gains and hitting multi-month lows, though some retail traders later framed it as balance-sheet strengthening amid the company’s ongoing interest in acquiring eBay Inc. (NASDAQ: EBAY ).

Some retail investors were still heavily bearish on GME.
