ServiceNow lost nearly a fifth of its market value in a single morning, on the same day its expanded OpenAI partnership put the company’s workflows inside ChatGPT. The ServiceNow OpenAI partnership is real, and it is ambitious. Wall Street just didn’t care, at least not on Thursday.
Shares of ServiceNow (NYSE: NOW) fell about 19% in early trading on Oct. 29, 2026, after the company reported third-quarter results the night before. MarketWatch reported the stock was on track for its largest single-day drop on record. Reuters put the premarket decline at 19%, with the stock sliding 19.6% at one point in the session, according to the Economic Times live blog.
The quarter itself was not a disaster. It was a miss in the places investors watch closest.
ServiceNow’s Q3 numbers and the guidance that sank the stock
ServiceNow reported third-quarter revenue of $4.11 billion, up 20.5% from a year earlier and about $20 million above the Wall Street consensus. Adjusted earnings per share came in at $1, against a consensus estimate of $1.02. That two-cent miss, on its own, would not normally erase a fifth of a company’s value.
Guidance did the damage. ServiceNow forecast fourth-quarter total revenue of $4.25 billion to $4.26 billion, below the $4.36 billion analysts expected. The company did raise its full-year subscription revenue and cash flow margin outlook, Reuters reported, but that was not enough to offset the weak fourth-quarter guide.
Analysts moved fast. At least ten brokerages cut their price targets on the stock, Reuters reported. Raymond James kept its “outperform” rating but lowered its target to $130 from $135, pointing to lagging subscription revenue and backlog growth and noting that ServiceNow’s AI initiatives have yet to show up in the numbers in a big way.
ServiceNow was not alone. Fortinet tumbled about 26% after its own results, and Zscaler and Salesforce traded lower in a broad software selloff. Reuters noted that the S&P 500 Software and Services Index is up just 6% so far this year, roughly half the gain of the broader S&P 500, as investors weigh whether AI models will disrupt traditional software businesses or simply become their next feature.
What the expanded ServiceNow OpenAI partnership actually includes
Buried under the selloff was a genuinely significant announcement. On Oct. 28, ServiceNow and OpenAI said they are expanding a partnership first struck in January 2026, when ServiceNow named OpenAI’s models, including GPT-5.2, a preferred intelligence capability on its AI platform. The companies say enterprises run more than 80 billion workflows a year on ServiceNow’s platform.
The centerpiece is a new ServiceNow plugin for ChatGPT, built on the Model Context Protocol, which went live on Oct. 28. It lets workers pull business context, incident history, and risk assessments into a ChatGPT conversation and take action on ServiceNow records without leaving the chat. An IT engineer could find similar past incidents, assess the risk of a planned change, and update a ticket from one conversation.
ServiceNow says its Action Fabric applies each company’s existing business rules and permissions inside ChatGPT, so a worker only sees and touches what they are already allowed to access in ServiceNow. The company remains the system where those actions are executed and governed, a point ServiceNow stressed in its announcement.
Beyond the plugin, the deal goes further. The companies are collaborating on Security and Risk products powered by OpenAI’s cyber models, a Codex integration in ServiceNow’s AI Workflow Factory for building applications, and voice-driven governance and risk assessment for ServiceNow’s Super Intelligence Control Tower. OpenAI is also joining ServiceNow’s newly announced Control Tower Alliance as a founding member, alongside Nvidia and Anthropic, according to reports on the announcement.
Rollout dates vary. Crypto Briefing reported that voice capabilities are slated for the first quarter of 2027, with the OpenAI-powered security features entering early access in January 2027 and reaching general availability in the second quarter. Both companies are also deploying each other’s tools internally: ServiceNow plans to give all of its employees access to ChatGPT Work and Codex, while OpenAI plans to make ServiceNow available across its own workforce.
Why this matters
Here is the tension in one sentence: ServiceNow just handed ChatGPT the keys to the enterprise workflow, and investors responded by selling the company that owns the workflow.
That sounds contradictory, and it partly is. But it also captures how Wall Street is grading software companies in late 2026. A partnership with OpenAI no longer counts as a strategy on its own. Investors want proof, in subscription revenue and backlog growth, that AI features are turning into money faster than AI models are eating into the core business. ServiceNow’s quarter gave them growth but not the acceleration they wanted, and the guidance gave them a reason to stop waiting.
For ServiceNow’s customers, the practical question is different. If the ChatGPT plugin works as described, routine IT work, incident triage, change approvals, and status updates, starts happening in a chat window instead of a ticketing queue. That is convenient, and it is also a shift in where enterprise work gets done. The company betting on governance, permissions, and audit trails as its moat is now letting the world’s most popular chatbot sit on top of all three.
ServiceNow’s pitch is that this is the point. The company describes the expanded deal as helping enterprises move “from AI reasoning to governed action,” with ServiceNow supplying the permissions, approvals, and context that raw model output lacks. If that framing holds, the plugin strengthens ServiceNow rather than bypassing it. If it doesn’t, and workers start treating ChatGPT as the system of record, ServiceNow becomes plumbing.
The stock market, for now, is pricing the second scenario. The next two quarters will show whether the first one was right.
Frequently asked questions
Why did ServiceNow stock drop 19%?
ServiceNow fell about 19% on Oct. 29, 2026, after its third-quarter profit missed estimates and its fourth-quarter revenue guidance of $4.25 billion to $4.26 billion came in below Wall Street’s $4.36 billion consensus.
What is the ServiceNow OpenAI partnership?
The expanded ServiceNow OpenAI partnership, announced Oct. 28, 2026, adds a ServiceNow plugin for ChatGPT, a Codex integration in AI Workflow Factory, and joint security products powered by OpenAI’s cyber models.
What does the ServiceNow ChatGPT plugin do?
The plugin lets workers find similar IT incidents, assess the risk of a change, and update ServiceNow records from inside a ChatGPT conversation, with ServiceNow’s Action Fabric enforcing each company’s existing permissions.
Is ServiceNow still growing despite the stock drop?
Yes, on paper. Third-quarter revenue rose 20.5% to $4.11 billion, and ServiceNow raised its full-year subscription revenue outlook. Investors punished the stock anyway because guidance and backlog growth fell short of high expectations.
