(NYSE:ANET) stock is the industry-wide move toward open-source Ethernet for backend AI networking. Historically, NVIDIA\u2019s proprietary InfiniBand was the only choice for connecting GPUs. However, hedge funds are betting that hyperscalers like Meta, Microsoft, and Google are switching to Arista\u2019s high-speed Ethernet to avoid vendor lock-in and lower their total cost of ownership. With the launch of the 7800R4 series, Arista has proven that Ethernet can now match InfiniBand\u2019s low latency while supporting clusters of over 100,000 GPUs. As AI data centers hit power and heat limits, Arista is also winning contracts through superior hardware engineering. The firm introduced XPO Liquid-Cooled Optics in March 2026. This module addresses the extreme heat generated by 800G and 1.6T networking.<\/p>\n While we acknowledge the potential of ANET as an investment, we believe certain AI stocks offer greater upside potential and carry less downside risk.
