Bitcoin (BTC) Markets Eye European Commission's Strictest DSA Tier for ChatGPT at 159.1M Users

ChatGPT Crosses the 45 Million Line

The European Commission on Monday placed OpenAI's ChatGPT under the strictest tier of the Digital Services Act (DSA), the European Union's rulebook for online platforms, classifying the AI assistant as a Very Large Online Search Engine. Reddit and Roblox were designated Very Large Online Platforms in the same decision. Anthropic's Claude, notably, was left out — and the reason is arithmetic, not merit.

Under the DSA, designation is a size test rather than a safety verdict. The statutory trigger is 45 million average monthly users in the European Union, and companies declare their own figures before the Commission acts. ChatGPT's search function reported 159.1 million, roughly 3.5 times the threshold. Reddit declared 57.2 million. Roblox cleared the bar by just 1.6 million — the narrowest margin of the three.

The meter runs both ways. The Commission stripped Stripchat of its designation in May 2025 after the adult platform's audience fell back below the line. And the institution has signalled it will keep watching user counts: the Commission's official announcement carries a warning from Executive Vice-President Henna Virkkunen that it “will not hesitate to designate any platform that meets the threshold for enhanced supervision under the Digital Services Act.”

The three designated services now have four months to comply, which sets the deadline at January 2027. They must then assess systemic risks spanning illegal content, minors, mental well-being and elections, and open their systems to independent audits. Penalties scale to 6% of global turnover, and the regulator has already shown willingness to use them.

Why Claude Stayed Below the Line

Anthropic's Claude escaped designation for one reason: its declared European user base sits under the legal cut-off. The DSA obliges providers to disclose user counts at least twice a year, and for the six months ending 31 October 2025 Anthropic concluded that Claude's European recipients fell well below 45 million. The exact figure was never published. That snapshot is now ten months old, a fresh one is already due, and Anthropic has since been pitching investors on a record public listing — a process that would subject its growth metrics to far closer scrutiny than a semi-annual regulatory filing.

Enforcement is no longer theoretical either. In December 2025 the Commission fined X €120 million, the first non-compliance decision under the law, set out in the regulator's own notice. The names added on Monday now join that same enforcement perimeter.

Scope matters for adjacent industries. The DSA targets consumer-facing reach — social networks, search, app distribution — not enterprise software, which is why videoconferencing providers such as Zoom sit outside it while consumer platforms crossing 45 million EU users cannot. Comparable disclosure regimes already bind retail brokers with crypto exposure: Robinhood, for one, reports user metrics under securities rules and operates a dedicated EU crypto arm. The pattern converging across jurisdictions is simple: consumer reach above a stated threshold triggers supervision, whatever the product category.

A Drafting Exercise for Crypto's Perimeter

For Bitcoin (BTC) the direct read-through is muted — BTC traded near $79,000 at the time of writing — but COINOTAG's desk reads this designation as precedent-setting. The Commission's notice binds the three named providers to audit and systemic-risk obligations from January 2027, and threshold-based regimes tend to expand their category lists over time. Consumer-facing Best Crypto Exchanges that already maintain EU entities are obvious candidates if Brussels ever extends the framework. Decentralized infrastructure is not automatically exempt either: masternode operators, appchain ecosystems and council-governed networks such as Hedera fall outside DSA scope today because no single provider holds the user relationship — but the size-test logic travels. Watch how the January 2027 audits land; that is where the template gets written.
