How OpenAI's Tracking Cookies Landed It Under Federal Investigation

OpenAI uses tracking cookies—small data files stored on your browser—across its websites to follow user behavior. Some of these cookies, according to the company's policy, can stick around for up to 400 days. Many come from advertising companies like Reddit and Meta, which means OpenAI's platforms are linked into the same tracking networks that power targeted ads across the internet. This cookie use has become a focal point as OpenAI faces a federal investigation into whether it handles user data fairly and legally.

The specifics are worth understanding. On openai.com, the company deploys tracking cookies from Reddit with names like _rdt_uuid and _reddit_s_event that linger for 90 days. Meta's cookies are more aggressive: some, like datr, persist for 400 days—more than a year. On ChatGPT itself, OpenAI sets consent-tracking cookies that last six months, alongside other cookies that stick around for a full year and track which device you're using.

This cookie infrastructure matters because it reveals OpenAI's ties to conventional digital advertising, even as the company publicly positions itself primarily as an AI research organization.

The Federal Scrutiny

The Center for AI and Digital Policy filed a complaint with the Federal Trade Commission in March 2023, arguing that OpenAI's data practices are unfair and deceptive. The FTC launched its own investigation in July 2023, examining claims that OpenAI violated consumer protection laws. The investigation represents the biggest regulatory challenge OpenAI has faced since ChatGPT went public.

The center later filed a supplemental complaint expanding its accusations about both initial data collection and subsequent changes to OpenAI's privacy policies.

What These Cookies Actually Do

Think of cookies as sticky notes your browser leaves behind on websites. They help sites remember who you are and what you do. OpenAI uses them for several purposes: to measure how effective its marketing campaigns are, to remember your language preference and device ID, and to track your interactions with the site.

The Reddit and Meta cookies are particularly telling. They enable what's called cross-platform behavioral analysis—essentially, they let advertisers build a picture of your browsing habits across multiple websites, not just OpenAI's. Meta's suite of cookies can create demographic profiles and track engagement patterns in fine detail. These persistence windows (how long the cookies stay active) go well beyond what's needed just to keep ChatGPT working smoothly.

OpenAI does use a consent management system on ChatGPT, which suggests the company recognizes it needs to get permission for some tracking, especially in regions like Europe with strict privacy laws. But the fact that these consent cookies last six months is worth noting—that's longer than many other tech companies hold onto them.

Why This Matters: The Bigger Picture

We've seen this regulatory pattern before. When cloud computing companies expanded rapidly in the mid-2000s, federal agencies struggled to apply existing consumer protection rules designed for earlier technologies. The outcome: enforcement actions that set industry-wide standards. The same thing is happening now with AI companies.

The real tension here is this: the privacy rules regulators have relied on were built for social media and e-commerce platforms, where the main concern was targeted advertising. But AI companies like OpenAI collect data for a different purpose too—training machine learning models. Those two uses of data raise questions that the old rulebooks don't cleanly answer. The FTC's investigation seems to be signaling that it views OpenAI's practices as potentially misleading to users, and that existing privacy protections should apply even in this newer context.

One detail from the FTC's focus is worth noting: the investigation mentions concern about "personal reputations." This suggests the agency is worried not just about standard tracking, but about how the data OpenAI collects—and uses to train systems—might affect people's privacy in ways that traditional tracking regulations don't fully cover.

What Comes Next

How OpenAI resolves these regulatory challenges will likely influence how other AI companies manage user data collection going forward. Right now, OpenAI's cookie practices technically disclose what they're doing, and the company hasn't violated the letter of current privacy law. But the FTC investigation could establish tougher standards for what counts as fair and transparent data handling in the AI era.

The broader context here is that regulators are still figuring out how to govern AI companies. This investigation will probably produce guidance—either through an FTC settlement or formal ruling—that becomes a template for the entire sector. For now, OpenAI sits at the intersection of two worlds: the AI development world, which needs large datasets, and the digital advertising world, which monetizes user data through tracking and targeting.

For now, OpenAI's use of cookies reflects that hybrid reality. Most people who use ChatGPT experience a simple conversational interface, but behind it sits a data collection footprint that stretches well beyond what that simple interface suggests.
