This week's artificial intelligence sector faces a crucial test as three major companies report earnings. NVIDIA will reveal its fiscal Q4 2026 results Wednesday, with Wall Street expecting a massive 67% revenue surge to $65.6 billion. Traders will scrutinize the production ramp of the Blackwell architecture chips and any roadmap updates for the Rubin chips, which could significantly impact the broader S&P 500. CoreWeave and Dell Technologies report Thursday, highlighting the physical infrastructure behind AI growth. CoreWeave's $56 billion revenue backlog signals strong demand, while Dell's $18.4 billion AI server backlog demonstrates aggressive order growth.

Analysts project CoreWeave revenue near $1.53 billion and Dell earnings at $3.53 per share on $31.6 billion in revenue. These reports will reveal if the AI boom still has room to run.
