liquid cooled optics module, a 12.8 Tbps pluggable unit delivering up to 204.8 Tbps per open compute rack unit with integrated cold-plate cooling and support for a broad range of Ethernet and coherent standards tailored to AI workloads. This move, alongside Arista’s broader AI networking vision and partnerships with Meta and Nvidia, highlights how higher-density, power-efficient optics could reshape AI data center architectures and expand the company’s role in next-generation infrastructure. We’ll now examine how XPO’s record 12.8 Tbps throughput and liquid cooling innovations may influence Arista Networks’ existing investment narrative. Find 59 companies with promising cash flow potential yet trading below their fair value.AdvertisementArista Networks Investment Narrative RecapTo own Arista Networks, you need to believe Ethernet will remain central to AI data center buildouts and that Arista can stay differentiated as speeds, density, and power demands rise. The new 12.8 Tbps XPO liquid cooled optics module fits cleanly into this thesis by reinforcing Arista’s role in high performance AI fabrics, but it does not, on its own, change the near term dependence on a few hyperscale customers, which remains the key risk. The most relevant prior announcement here is the 7800R4 and 7280R4 launch for 800G switching in late 2025, since those platforms provide the switching backbone that XPO optics are intended to plug into. Together, they point to a product stack aimed squarely at AI clusters, which could be supportive for the main catalyst of continued AI data center investment, while also testing Arista’s ability to keep its hardware and software differentiated against white box and vertically integrated rivals. Yet, against this promising AI optics story, investors still need to be aware of how much hinges on a small group of hyperscale buyers... Read the full narrative on Arista Networks (it's free!)Arista Networks' narrative projects $13.6 billion revenue and $5.4 billion earnings by 2028. This requires 19.5% yearly revenue growth and a roughly $2.1 billion earnings increase from $3.3 billion today.Uncover how Arista Networks' forecasts yield a $163.37 fair value, a 25% upside to its current price.Exploring Other PerspectivesANET 1-Year Stock Price Chart Some bullish analysts were already assuming Arista could reach about US$15.4 billion in revenue and US$5.9 billion in earnings by 2028, so if you see XPO as reinforcing the AI buildout thesis rather than heightening customer concentration risk, your view may be closer to that more optimistic camp, reminding you that reasonable investors can look at the same news and reach very different conclusions.Explore 17 other fair value estimates on Arista Networks - why the stock might be worth just $127.06!Reach Your Own ConclusionDisagree with existing narratives?
