AI Rally Isn't Over: Nvidia-OpenAI Deal and Big AI Spend Extend Momentum

AI still has momentum as Nvidia leads, capital flows build, and the Fed's tilt to cuts supports risk. Stay invested but selective, tracking capex, storage, and revisions.

AI Stock Pickers: Three Reminders That Matter Now

This week delivered clear signals for allocators leaning into AI. The market is still taking its cues from Nvidia (NVDA). As long as Nvidia executes and the stock grinds higher, risk appetite broadens. That's the tape.

The bigger takeaway: the "AI is peaking" narrative keeps getting disproven by capital flows, capex plans, and deal activity. If you're underwriting AI exposure, the data still argues for staying constructive.

Three reminders for allocators

  • Nvidia sets the tone: NVDA strength remains a leading indicator for broader risk-on behavior. The new $100 billion alignment with OpenAI underscores durable demand for compute and models. Beneficiaries extend well beyond semis into data center infrastructure, select aerospace/defense programs, and software tied to inference workloads.
  • Retail matters: Opendoor (OPEN) and Better Home & Finance (BETR) saw sharp moves as influential voices on X drove attention and liquidity. If you're a CEO, ignoring retail is a risk. If you're an investor, track narrative momentum alongside fundamentals.
  • The Fed is a tailwind: With policymakers signaling a bias to cut, buy-the-dip behavior stays supported. Easier financial conditions lift multiples for secular growers and capital-intensive AI buildouts.

Fresh proof points: AI is not peaking

  • Platform consolidation: Nvidia's expanded alignment with OpenAI signals continued spend on training and inference capacity.
  • Capex escalates: Alibaba (BABA) plans to spend more than $50 billion on AI models over three years, lifting its prior guidance from earlier this year.
  • Memory tailwinds: Micron (MU) flagged tightening storage needs from hyperscalers and a step-up in NAND SSD deployments into 2026, implying improving industry conditions.
  • New challengers funded: Groq raised $750 million at a $6.9 billion post-money valuation, adding competitive pressure and innovation to accelerators and inference.

Positioning ideas (practical and risk-aware)

  • Core-satellite structure: Keep a core in proven AI enablers (compute, memory, networking) and satellite exposure to emerging names with asymmetric optionality. Think NVDA for core execution; look to MU and select storage/network names for the stack; selectively evaluate earlier-stage players like Groq for optionality.
  • Follow the demand chain: Track hyperscaler AI server deployments, data center storage mix shift to SSDs, and model training intensity. Revisions and utilization metrics are more telling than headlines.
  • Respect the retail bid: Monitor social momentum, short interest, and options activity in names with high retail ownership. Liquidity and borrow dynamics can overwhelm fundamentals in the short term.
  • Risk management: Use staged entries on weakness while the Fed tilts dovish. Focus on earnings revision trends over headline multiples; pair longs with trims into euphoric spikes.

Key watch items this quarter

  • Policy path: Speeches and the meeting schedule from the Federal Reserve will shape multiples and dip-buying behavior. Federal Reserve monetary policy
  • Capex guides: Hyperscaler and leading AI platform updates on data center spend, networking upgrades, and memory procurement patterns.
  • Supply signals: Lead times for accelerators, SSD mix in servers, and any signs of relief in HDD bottlenecks.

Bottom line

The setup for AI remains intact: rising capex, expanding use cases, and supportive policy. Bears will struggle while cuts are in play and the buildout continues. Stay invested, stay selective, and let revisions drive conviction.
