Wall Street showed mixed results across recent trading sessions as swings in AI stocks continued to unsettle investors. The Dow Jones, S&P 500, and Nasdaq moved in different directions depending on the day, with technology stocks often bearing the brunt of losses. Strong earnings reports from major companies including Microsoft, Alphabet, Apple, and Amazon helped offset declines in the AI sector. The U.S. economy grew at a 2.1% annual rate in the first quarter, slower than some analysts expected.
Nvidia CEO Jensen Huang unveiled a $10 billion plan for modular and quickly-deployed AI data centers at GTC Berlin. The initiative aims to cut the lengthy assembly times that currently delay AI computing projects. Nvidia and Schneider Electric are also piloting a digital twin for AI data centers at a site in Portugal, combining models for power, cooling, and AI workloads to let operators preview changes before they go live.
SpaceX shares surged on the back of strong AI computing demand. CEO Elon Musk said the company could reach 20 gigawatts of data-center capacity by late 2027. SpaceX generated $7.6 billion in revenue in Q3 2026 through its Super Intelligence division, underscoring how AI momentum is reshaping the business. The broader AI boom also lifted Taiwan's stock market to new records, while Korea's KOSPI fell sharply after peaking above 9,000 points.
Coinbase is moving into agentic finance, aiming to give AI agents wallets and financial accounts. Its x402 payment system now handles hundreds of millions of transactions per month, and companies like AWS and Cloudflare are enabling x402 gating on their networks. Separately, Pigment raised $250 million to strengthen its agentic AI platform, which helps enterprises with business planning and lets AI agents run workflows with human approval.
Concerns about AI risks are also surfacing in financial markets. Japan brokerage IwaiCosmo blamed unauthorized trading on the malicious use of AI. Meanwhile, a new diagnostic benchmark called DecisionPivot tested 40 decision models and found that high overall scores can mask large differences in decision quality. On the infrastructure side, NextDC hit a nearly nine-year low in its share price after a key power distributor suspended work at a Melbourne facility due to safety concerns and local opposition.
