AI Stocks Surge, Nvidia vs AMD Valuation Debate

AI stocks continued to power Wall Street higher on Tuesday, pushing major indices toward record levels. The S&P 500 rose between 0.5% and 0.7%, while the Nasdaq climbed 1.2% to 1.3%. Broadcom led the gains with a 4.5% surge, and NVIDIA and Alphabet also posted strong results. The technology sector drove most of the market's upward movement, with investors showing renewed enthusiasm for AI-related companies.

Nvidia and AMD remain the dominant players in the AI chip market, but their valuations tell an interesting story. Nvidia's data center division earned $89 billion in Q2 FY2027, compared to AMD's $6.7 billion. Despite Nvidia growing faster at 117% versus AMD's 107%, AMD stock trades at roughly three times Nvidia's forward earnings multiple. Nvidia's market cap sits at $5.21 trillion while AMD's is $867 billion, leading some analysts to argue Nvidia is the better buy at current prices.

On the enterprise side, several companies launched new AI products and partnerships. Cato Networks introduced Cato AI Endpoint, a tool that helps organizations secure AI usage across browsers, desktop apps, and local agents. Oracle unveiled Fusion Companion, an orchestration layer that lets users kick off business tasks through external AI assistants like ChatGPT. Sarvam AI signed a memorandum with India's Headquarters Integrated Defence Staff to build sovereign AI capabilities for the Indian military, developing its own 105-billion-parameter language model.

Other notable developments include Lumia Security integrating Anthropic's Claude Compliance API, allowing organizations to monitor Claude Enterprise activity including conversations and file uploads. Meanwhile, Sweden banned government workers from using OpenAI's ChatGPT and Anthropic's Claude over data security concerns, though Microsoft CoPilot remains permitted under stricter controls. Amazon sent a memo to engineers telling them to stop chasing AI usage metrics like token usage, calling them flawed measures that raise spending and add complexity.

Alphabet continues to face scrutiny as an AI player, with its stock staying nearly flat while the S&P 500 rose 13%. Gemini reaches hundreds of millions of Google users but has not landed major enterprise deals, and Gemini-powered search results are reportedly hurting the core search business. Microsoft is offering exit packages to about 60,000 employees as it increases spending on AI investments. ServiceNow saw price targets raised by Cantor Fitzgerald and BofA ahead of Q3 2026 results, driven by its AI capabilities and focus on customer control.
