ChatGPT Just Got a Major New Label in the EU: 'Very Large Online Search Engine' – Here's What It Means

Well, here's some news that's bound to ripple through the tech world: The European Union has made a rather significant move, officially labeling ChatGPT as a 'very large online search engine' under its much-talked-about Digital Services Act (DSA). And it's not alone; popular platforms Reddit and Roblox also found themselves in the EU's spotlight, designated as 'very large online platforms.' But for ChatGPT, that specific 'search engine' tag? That's quite a twist, and it comes with a whole new set of responsibilities.

This landmark decision, announced on August 31, 2026, isn't just a label; it's a legal trigger. The DSA, remember, is the EU's ambitious framework designed to create a safer, more accountable online environment. At its heart, it sets a threshold: any platform or service hitting an average of 45 million monthly active users or recipients within the EU is deemed 'very large.' It’s a way of saying, 'Hey, your influence is massive, so your responsibility needs to be, too.'

So, how did these services measure up? Well, ChatGPT, astonishingly, reported around 159.1 million average monthly active recipients for its search functions in the EU during the six months leading up to March 31, 2026. That's a huge number, placing it squarely in the 'very large' category. Reddit, meanwhile, clocked in at no more than 57.2 million monthly users in the first half of 2026, and Roblox wasn't far behind with an estimated 46.6 million monthly users. All comfortably above that 45-million mark, sourced directly from their own DSA disclosures, no less. Now, the 'search engine' label for ChatGPT is particularly intriguing. The European Commission itself described ChatGPT as a 'hybrid service.' Why? Because it doesn't just chat; it actively responds to user prompts and queries, often by, you guessed it, searching the web. It's that search capability that tipped the scales for this designation.

What does this designation actually mean for these tech giants? A lot, frankly. They now face a raft of additional, rather stringent, obligations that go way beyond what smaller platforms need to do. We're talking about a mandate to identify, assess, and, crucially, mitigate 'systemic risks.' Think about it: risks like the spread of illegal content, potential negative impacts on minors, fundamental human rights, even how it could affect electoral processes or public security. It's a broad spectrum of responsibility. Beyond that, they'll need to undergo independent audits – at least annually – just to ensure they're truly playing by the rules. Data sharing is also on the agenda, with requirements to provide information to the European Commission and national authorities. And, perhaps most fascinating for the research community, they'll need to allow vetted researchers access to their platform data, all in the name of studying these systemic risks. Oh, and if they're dishing out recommendations, they'll need to offer an option that isn't based on your personal profile. Plus, if they're showing ads, a public ad repository is a must. Quite a list, isn't it?

This isn't just bureaucratic red tape; it's about holding power to account. Henna Virkkunen, the Commission's executive vice-president for tech sovereignty, security, and democracy, summed it up perfectly. She stated, and I quote, 'These new designations mean that ChatGPT, Reddit and Roblox will now be held to a higher standard of scrutiny and accountability in the European Union, in line with their large impact on our citizens and society.' It’s a clear message: with great reach comes great responsibility.

Now, these companies aren't left without time to adapt. They've been given a four-month window from the notification date to fully comply with these beefed-up DSA obligations. But make no mistake, the stakes are incredibly high. Should they fail to meet these new standards, the penalties are severe. We're talking about fines that could soar up to a staggering 6% of a company's global annual revenue. That’s enough to make even the biggest tech players sit up and take notice.

It’s important to clarify something here: this designation itself isn't a judgment of wrongdoing. The European Commission isn't saying these companies have broken rules. Instead, it’s a proactive step, simply identifying them as 'very large' due to their user numbers, which then automatically triggers these enhanced responsibilities. Enforcement, should any non-compliance arise, would be an entirely separate process.

Ultimately, this move by the European Commission underscores the EU's serious commitment to shaping the digital landscape, especially concerning AI and pervasive online platforms. As we navigate an increasingly complex digital world, it’s fascinating to watch how these regulations will unfold and how tech giants like OpenAI (the creators of ChatGPT) will adapt to this new era of heightened accountability in Europe.
