Datadog Surges 94%: Why Wall Street Is Suddenly Shrugging Off a $100 Million OpenAI Scare!

Datadog has emerged as one of the standout beneficiaries of the artificial intelligence boom, with its shares rising approximately 94% in 2026 through October 19, despite concerns over a major customer reducing its spending commitments. The latest catalyst came from Bernstein, which upgraded the stock from Market Perform to Outperform and raised its price target from $237 to $350, citing unexpectedly strong demand from AI customers. The upgrade follows a reported annualized contract reduction exceeding $100 million involving Datadog’s largest customer, which analysts believe to be OpenAI. However, accelerating consumption among other AI customers could offset much of that setback, potentially changing the investment narrative. Datadog’s second-quarter revenue increased 36% year-over-year to $1.12 billion, while growth among non-AI customers also accelerated. Nevertheless, the stock’s substantial appreciation has raised questions about valuation, customer concentration, and the sustainability of AI-driven spending. Here are four factors shaping Datadog’s outlook.
