OpenAI is in early talks to acquire Trail of Bits, a startup that finds and fixes vulnerabilities in open-source software, in what would mark a significant push by the artificial intelligence company into the cybersecurity arena.
The report, carried by The Information and picked up widely on Wednesday, immediately rattled investors in the security software sector, sending several leading cybersecurity stocks lower in a single session.
Markets price in a new rival
CrowdStrike shares fell about 2% to around $256, Palo Alto Networks declined nearly 3% to near $386, and Fortinet retreated more than 3% to roughly $184.50. Shares of Okta, Zscaler and other cybersecurity names also moved lower. The slide reflects a recurring market worry: that leading AI model makers such as OpenAI and Anthropic could eventually compete directly with incumbent cybersecurity vendors.
That anxiety first flared earlier this year, then eased after the model makers announced projects to screen their AI systems for safety before formal release. The latest acquisition report has revived it. One view circulating in the market is that the model makers could launch their own cyberdefense products as early as 2027 to help customers counter threats from cutting-edge AI models.
Partnerships and blurred lines
The boundaries between the two industries have already been blurring. CrowdStrike announced product availability through Anthropic's Claude marketplace in September, and Palo Alto Networks said in the same month that it was offering a service built on Anthropic and OpenAI models. Cybersecurity firms are racing to embed AI into nearly every stage of threat detection, investigation and response — while attackers are using AI tools of their own.
Analysts note that a worsening AI-driven threat landscape is one reason cybersecurity valuations have jumped this year, with CrowdStrike and Palo Alto Networks both posting strong gains in 2026. The computer security industry group currently ranks near the top of sector trackers, underscoring how much investor interest is riding on who wins the AI-security race.
Neither OpenAI nor Trail of Bits has made a public announcement about the talks, which remain at an early stage.
