In December 2025, Meta made a quiet but consequential decision: it shut rival AI assistants out of the WhatsApp for Business API, leaving only its own Meta AI with access to one of the world's most widely used messaging platforms. Within months, that move had drawn the attention of the European Commission, which launched a formal antitrust investigation and has now gone further still — ordering Meta to reverse course before the inquiry is even complete. The Commission's interim ruling, announced this week, gives Meta just five working days to restore third-party AI assistants to the WhatsApp for Business API on the same terms that existed before the ban. The urgency, Brussels argued, is that fast-moving technology markets do not wait for slow-moving legal proceedings.
"In rapidly evolving markets, competition can be lost long before a final decision is adopted," said Teresa Ribera, the Commission's executive vice-president for clean, just and competitive transition. Regulators described Meta's original ban as an apparent abuse of its dominant position in European markets — one that risked causing "serious and irreparable harm" to competition. Should Meta refuse to comply, it faces fines of up to ten per cent of its total global turnover. Meta's response was immediate and combative.
The company accused the Commission of allowing firms such as OpenAI — among the most valuable AI businesses on the planet — to exploit a paid commercial product without charge.
