DMA · MESSENGER UNBUNDLING
ChatGPT returns to WhatsApp
in Europe.
ChatGPT is once again usable inside WhatsApp for European users. The European Commission's June 11 order under the Digital Markets Act (DMA), which required Meta to open in-app AI assistants on WhatsApp to rivals, took effect on July 15. It is the first time regulators have actually cut into a gatekeeper's platform-embedded AI lock-in.
The News
A June 11 order that
opened WhatsApp by July 15
The first EU intervention that specifically unbundles an in-app AI assistant.
On June 11, 2026 the European Commission's DG COMP issued a formal order under Article 7 of the Digital Markets Act (DMA), instructing Meta to open WhatsApp's in-app AI-assistant surface to third parties. Meta was designated a gatekeeper in 2023, and WhatsApp is one of the 22 core platform services listed under the DMA. What made this order unusual was its short compliance window of roughly four weeks. In line with that deadline, on July 15 both OpenAI and Meta announced that ChatGPT is once again available inside WhatsApp for European users. Europeans can now add the official ChatGPT bot and summon it from ordinary WhatsApp threads. The specifics appear in the European Commission's notice and OpenAI's announcement.
The setup for this dates back to 2024. In September 2024 Meta integrated Meta AI directly into WhatsApp in Europe, wiring it into both the search bar and the chat list — effectively making it the default in-app assistant. OpenAI had launched its US-only WhatsApp bot at +1-800-CHATGPT that December, but Europe was closed off because Meta did not permit rival AI bots inside the app. The July 15 update is the regulator undoing that lock-in after almost two years, and Meta's follow-up statement explicitly framed the change as DMA compliance.
By the Numbers
The scale of the shift
Widely cited market estimates put WhatsApp's European monthly active user base above 400 million, so OpenAI's ability to re-deploy an official bot there is far from trivial. Of the 22 core platform services under DMA gatekeeper designation, this is the first case where AI-assistant coexistence was mandated by name — a signal that the framework has moved from designation into active unbundling enforcement.
Why It Matters
Why the DMA remedy reached AI now
The DMA has been in force since 2024, but this July is the first time it was applied to "AI-assistant surfaces".
Article 7's scope extended to AI
Article 7 requires interoperability for "Number-independent Interpersonal Communications Services". Originally the target was messaging itself, but once Meta AI was wired into WhatsApp's conversational surface, the Commission explicitly interpreted the AI assistant as falling under the same article. That framing is the trigger.
The "de facto default" was made visible
Meta AI could be reached from the search bar, the chat list, and group suggestions — three distinct entry points that made it the only realistic in-app AI for European users. The Commission cited each of those surfaces by name as a functional lock-in.
Roughly four weeks from order to effect
Earlier DMA enforcement cycles ran months from compliance report to remedy. This one set a mid-July implementation deadline against a June 11 order. EU competition lawyers read the pace as a signal that Brussels expects the same speed in future comparable cases.
Who's Affected
Who feels this, and how
Business leads (EU operations)
WhatsApp is once again a viable European customer-service and sales layer mediated by ChatGPT. The choice of AI vendor — impossible to make under Meta-AI-only — is back in the brand's hands.
Product managers
The "messenger-resident product" distribution playbook is revived. Scaling in Europe without shipping a standalone app is possible again — the tactic OpenAI first tried in the US in 2024, now available inside the EU.
Marketers
A reminder that conversational platforms are rented land. Watching a lock-in break by regulation reframes the case for reinvesting in owned apps and first-party data while balancing external channels.
The Counterpoint
Opening is not the same as winning
Formal DMA compliance and real user behavior are separate variables.
(1) Default bias. Meta AI stays pre-installed as WhatsApp's first-run assistant. Adding ChatGPT still requires searching and enrolling the official bot; behaviorally, Meta AI likely retains most of the traffic in the near term. (2) Fragmented UX. Multiple AI bots in one chat list push the choice of "which AI for which task" back onto the user. (3) Unresolved data handling. How conversation context and attachments flow between OpenAI, Meta and other providers is left to implementation. Updated joint privacy notices from Meta and WhatsApp are the next focal point.
What to Do Next
What to do next, practically
| Short term (0-3 mo) | Medium term (3-12 mo) |
|---|---|
| Pilot the ChatGPT WhatsApp bot on European accounts and measure adoption | Build a branching distribution plan for possible parallel unbundling of Signal, Telegram, LINE, and WeChat |
| Benchmark response quality and latency between Meta AI and ChatGPT; redefine EU-facing KPIs | Design attribution for in-messenger AI conversions across owned apps vs. rented channels |
| Review EU data-processing disclosures with legal and DPO; update customer privacy notices | Document the split between "owned conversational platforms" and rented ones as an explicit executive policy |
The remedy is EU-only for now, so users in Japan and elsewhere will not see WhatsApp change in the near term. But the regulatory template matters: it may propagate to Threads and other messengers, including Japanese ones like LINE. The fastest first move is to refresh the question of "which AI layer we anchor on inside rented conversational platforms", starting from the European operation.
