Arm Holdings Stock Fell 6% in a Day as an OpenAI Revenue Report Hit Chip Stocks. Here’s Where OpenAI Touches Arm’s Business
Arm Holdings (ARM) stock fell 6.48% to $275.29 on October 8, 2026, amid a broader chip sector selloff triggered by OpenAI revenue reports. The decline was steeper than peers like NVIDIA and Intel, partly due to Arm's higher beta. OpenAI's potential impact on Arm's business includes AGI CPU orders and SoftBank's licensing revenue contributions. Arm's fiscal Q2 results, due November 4, will be closely watched for SoftBank's licensing contribution.
