Arista Networks (ANET) took a 10% hit in after-hours trading despite posting Q3 2025 results that, on the surface, looked pretty good. Revenue up 27% year-over-year? Not bad. Shares up nearly 40% YTD? Even better. So, what gives?
The knee-jerk reaction is always to blame "mediocre guidance," which is what some outlets are reporting. But let's dig a little deeper than the headlines. AMD, for example, also saw its shares dip despite a top-and-bottom-line beat and strong Q4 guidance. The market's a fickle beast, and sometimes good news just isn't good enough. (Especially when expectations are sky-high, which they often are in the tech sector.)
The AMD case is interesting because it highlights the AI infrastructure hype cycle. AMD is riding the wave with its MI450 chips, securing deals with OpenAI and Oracle. The CFO even said the OpenAI deal is "expected to deliver tens of billions of dollars in revenue." That's the kind of statement that sends stock prices soaring.
But here's where the skepticism kicks in. As Morgan Stanley analyst Joseph Moore pointed out, AMD needs to offer a better ROI than NVIDIA to truly gain market share. And customers are still raising questions about rack density and ecosystem issues. In other words, the potential is there, but the execution is still a question mark.
Arista Networks, while not directly comparable to AMD, is also playing in the AI infrastructure space. They're providing the networking backbone for these massive data centers. So, is the market starting to realize that the AI gold rush might not be as easy as everyone thought? Is the market starting to see the picks-and-shovels companies as less attractive than the chip designers?
I think so.
And this is the part of the report that I find genuinely puzzling. If Arista is truly the backbone of AI, shouldn't its stock be soaring higher than AMD? Why the discrepancy?
One possible explanation is that the market is anticipating increased competition. Arista isn't the only player in the networking game, and as AI infrastructure scales, other companies will be vying for a piece of the pie. Details on this increased competition remain scarce, but the impact is clear.
Another factor could be the nature of Arista's revenue. While AMD is landing splashy deals with OpenAI and Oracle, Arista's growth might be more dependent on the overall build-out of data centers. If those build-outs are slower than expected, or if customers are finding ways to optimize their existing infrastructure, Arista's growth could be capped.
Interestingly, one of the "sources" listed in the fact sheet is a denial-of-service message. That's right, a literal error message stating, "Access to this page has been denied because we believe you are using automation tools to browse the website." While seemingly irrelevant, it inadvertently reveals a key aspect of modern financial analysis: the reliance on automated tools and web scraping to gather information. The irony of being blocked for using the very tools that drive market analysis is almost poetic. Access to this page has been denied.
Is this a sign that the data is becoming harder to get? Is the information we are using to make decisions becoming less accurate?
The 10% drop in ANET stock price today isn't necessarily a cause for alarm. It's a reminder that the market is driven by sentiment as much as it is by fundamentals. And right now, the sentiment around AI infrastructure might be shifting. It was about 27% growth, to be more exact, 27%. Still, the market didn't seem to care.
The market's reaction to Arista's Q3 results feels like a collective tightening of the belt. The initial exuberance surrounding AI infrastructure is giving way to a more sober assessment of the challenges and the competition. It's not that Arista is doing anything wrong, it's that the market is starting to understand the complexity of the AI landscape. And that complexity often translates to lower valuations.
