321 S&P 500 Companies Mention AI in Earnings Calls

AI continues to dominate corporate conversations across the S&P 500. Between June 15 and August 28, 321 companies mentioned AI during earnings calls, signaling widespread interest in the technology. Nvidia and Alphabet have been the primary engines behind a stock rally that has pushed the index up 78% over three calendar years. Despite concerns about heavy infrastructure spending, adoption shows no signs of slowing.

On the spending front, Anthropic revealed plans to invest $518 billion over the next decade on cloud and computing power. The company has locked in long-term deals with Amazon and Alphabet. Its revenue has surged from $4.6 billion in 2025 to a $65 billion annual run rate by July 2026, underscoring how quickly AI products can scale.

Chipmakers are also riding a wave of optimism. AMD stock rallied after Citi lifted its price target to 800 from 575, citing demand driven by agentic AI. Mizuho Securities also raised its target while maintaining an outperform rating. Nvidia shares climbed 2.1% to a new all-time high, with analyst Dan Ives suggesting earnings estimates could be 20% to 30% too low. Enterprise AI and physical AI applications are broadening demand beyond major cloud customers.

In the financial sector, Jump Trading is using GPT-6 Astra to scale its quantitative research. The firm is building agents that allow researchers to run multi-day analyses with recursive code development. Human review remains in place at key checkpoints to meet regulatory requirements.

Cybersecurity stocks have surged as AI agents raise safety concerns. Leaders at Anthropic and OpenAI have flagged rogue agents as the biggest current risk. Morgan Stanley projects corporate cybersecurity spending will grow 23% annually through 2028, with potential to reach 33% if major attacks occur. CrowdStrike, Rubrix, Palo Alto Networks, and Okta are among the firms benefiting from this trend.

Zscaler CEO Jay Chaudhry said AI models are fueling demand for security products. Shares rose about 4% after the company reaffirmed guidance at its investor day. Meanwhile, Italian startup SimpL raised €1.2M for its AI-powered B2B sales tool, which uses a proprietary knowledge graph to help sales teams target decision-makers. The platform operates on a results-based model, charging only for qualified meetings.

The Justice Department rebranded its AI unit, renaming the Office of the Chief Information Officer to the Office of the Chief Artificial Intelligence Officer. A memo titled Super Intelligence directed the change, which extends to court filings, as part of a broader technology modernization push.

On the research front, a new method called Exploration-Preserving Policy Optimization (ExPPO) aims to improve reasoning coverage in AI learning. It reshapes credit assignment using prompt-relative and length-normalized measures, achieving higher accuracy. Separately, a study found that large reasoning models resist self-monitoring, self-reporting misbehavior in only about 16% of warranted cases when tool use was optional.
