The US tech giant has responded by accusing the European Commission of regulatory overreach

The European Commission has demanded that Meta - which owns Facebook, Instagram and WhatsApp - give competitors' AI assistants free access to its messaging and social media platforms.

The interim measure will remain in place until the conclusion of an antitrust investigation against the American tech giant, the EU's main executive body said in a statement on Tuesday.

Meta could face a fine of up to 10% of its global annual turnover if found guilty of abusing its market power to undercut its rivals.

The probe into Meta was launched in December 2025 when artificial intelligence developers from the US, France and Spain complained about the California-based company's decision to block access to its WhatsApp for Business application programming interface (API) to all competitors.

Only its own Meta AI remained connected to the messaging app, which has over 3.3 billion active users worldwide. It's also integrated into Meta's social media platforms, Facebook and Instagram.

In March, the company allowed external AI chatbots to access WhatsApp for a fee, but Brussels argued that it was too high and not economically sustainable for rivals.

Meta now has five working days to make the use of WhatsApp for Business API free, like it used to be before October 2025, according to the European Commission.

EU antitrust chief Teresa Ribera said that the body acted to "preserve choice for citizens across Europe on the AI assistants they want to use with WhatsApp, without that decision being made for them."

The measure will also "safeguard competition in the growing market for AI assistants, by preserving a key entry point to reach consumers in Europe - WhatsApp - and allowing AI companies to innovate, scale up and reach their full potential," Ribera added.

A Meta spokesperson said in an-email to Reuters that the company disagrees with the order and is planning to appeal against it.

"The European Commission has decided that OpenAI and some of the largest companies in the world can use the paid-for WhatsApp Business product for free. This is regulatory overreach subsidized by the many European companies that pay," the spokesman stressed.

CNBC reported in April that Meta, Google and Apple have been ordered to pay around $7 billion in fines by the EU for antitrust and privacy breaches since the start of 2024. This prompted the administration of US President Donald Trump to accuse Brussels of unfairly targeting the US tech firms, with the European Commission insisting that it's only protecting the bloc's consumers.
