Welcome to Markets Desk, your midday read on what's moving markets and the companies behind them.
Arista Networks is the standout on the tape today, shares climbing roughly five percent after the networking equipment maker posted third-quarter earnings that beat expectations and issued a stronger-than-expected forward outlook. The numbers confirm what investors have been watching closely — AI data center buildout is still accelerating, and Arista sits directly in that spending path.
Meanwhile in the chip space, it has been a punishing stretch for semiconductors. The iShares Semiconductor ETF shed more than eight percent in a single session late last month, erasing an estimated one trillion dollars in market value. Intel's earnings triggered the worst single-day collapse for that stock in fifty years, and the fallout forced at least one five-star analyst to reset their price target on Nvidia as the sector recalibrates.
Turning to the AI infrastructure story, a new threat is emerging for corporate finance teams. Cybercriminals are stealing company AI credentials and reselling unauthorized access to large language models, leaving the victimized companies to absorb cloud bills that can climb into seven figures. Google's cybersecurity unit flagged the trend this week, and CFOs are being urged to treat LLM access as a critical financial control.
That's the tape. Markets Desk, signing off the floor.
