US tech billionaire Elon Musk’s social media platform X said on Friday it has filed an appeal at the General Court of the European Union against a €120 million (about 141.56 million) fine imposed by the European Commission under the bloc’s Digital Services Act (DSA).

In a statement posted by X’s Global Government Affairs account on the platform, the company said it is challenging the Commission’s December 5, 2025, decision. It described the Commission’s decision as the result of an “incomplete and superficial investigation,” “grave procedural errors” and a misinterpretation of obligations under the DSA, while alleging breaches of rights of defence and basic due-process requirements.

The Commission announced the €120-million penalty in December last year, saying X had failed to comply with DSA transparency requirements. It cited concerns including the design of the platform’s paid verification “blue checkmark,” the transparency of its advertising repository, and researchers’ access to public data.

X said the case marks the first judicial challenge to a DSA non-compliance fine and could set precedents for enforcement and penalty calculations under the regulation. The company added that it remains committed to user safety and transparency.

Information published on the Court of Justice of the EU website shows the General Court has registered several related actions, all lodged on February 16, 2026, and currently listed as pending, including challenges brought by X and its corporate entities, a separate action linked to Elon Musk, and another filed by the AI-related company associated with him.

The suit against EU is the latest in a series of cases Musk companies are involves in. The others are:

Advertiser Boycott Lawsuits (X): Musk’s platform X has sued major brands and the World Federation of Advertisers (WFA), alleging a “massive” and illegal boycott that deprived the company of advertising revenue following his 2022 acquisition.

In 2025, this suit was expanded to include companies like Lego, Nestlé, Tyson Foods, and others.

Lawsuit against New York (X): X sued New York State to block a law requiring social media companies to disclose their methods for addressing hate speech and misinformation, arguing it violates the First Amendment.

Lawsuit against OpenAI & Apple (xAI): In August 2025, Musk’s AI Company, xAI, sued OpenAI and Apple, alleging their partnership violates competition law and hurts competition.

Lawsuit against Former Engineer (X): X sued a former senior engineer, Yue, in late 2025, accusing her of stealing proprietary software code to create a rival firm.

There are also cases in which X has been sued. Some of them are:

SEC Lawsuit over Twitter Stake (2025): The US Securities and Exchange Commission (SEC) sued Musk in January 2025, alleging he failed to promptly disclose his 2022 acquisition of Twitter stock, allowing him to save $150 million. In February 2026, a US judge denied Musk’s bid to dismiss this lawsuit.

OpenAI Countersuit (2025): Following Musk’s lawsuit, OpenAI countersued him in April 2025, claiming he is using “bad-faith tactics” to slow down their business and control AI technology. A judge set a March 2026 trial date for this fight.

Severance Pay Lawsuits (X): X reached a settlement in October 2025 regarding a lawsuit from former Twitter executives who claimed they were owed $128 million in severance, as well as a separate $500 million suit from former rank-and-file employees.

DOGE/Government Injunction (2025): A federal judge blocked Musk’s “Department of Government Efficiency” (DOGE) from accessing certain sensitive Treasury Department systems in a lawsuit related to his advisory role.

Grok Deepfake Lawsuit (xAI): In 2026, Ashley St. Clair sued xAI, alleging the company’s Grok AI generated deepfakes
