Two governments picked the same date on purpose, and it has already gone by.

As of August 2, 2026, Article 50 of the EU AI Act applies. On the same day, California’s AI Transparency Act became operative — not on January 1, 2026 as originally written, but on August 2, because AB 853, signed into law on October 13, 2025, moved the date specifically to line up with the European deadline.

That alignment is the signal. Two of the largest regulatory blocs for digital content decided that synthetic media should become machine-detectable starting the same morning. AI labelling stopped being an ethics-panel topic and became a compliance date seven weeks ago.

Who the obligation is actually on

This is where most of the guidance circulating right now is wrong, and the distinction decides whether any of it is your problem.

Article 50 splits its duties. Providers of AI systems that generate synthetic audio, image, video or text must ensure the outputs are marked in a machine-readable format and detectable as artificially generated or manipulated. That obligation sits on the people who build and ship the model — the generation vendors, not the person typing the prompt.

Deployers carry a different and narrower duty: disclosure. If you publish deepfake content, or AI-generated text published to inform the public on matters of public interest, the AI Act requires that this be disclosed. The European Commission’s own FAQ on the transparency obligations is the right starting point for working out which side of that line a given output falls on, and this is a case where reading the primary text beats reading a summary — including this one. Nothing here is legal advice, and a project with real exposure in either jurisdiction should get an actual opinion.

For a small creative operation, the practical translation is usually: your vendor owes the watermark, you owe the honest label.

The December extension nobody mentions

One detail keeps getting dropped from the coverage, and it matters for anyone who assumed their existing tools were already compliant.

Under the AI Omnibus provisional agreement reached in May 2026, generative AI systems already on the market before August 2, 2026 have until December 2, 2026 to meet the machine-readable marking requirement in Article 50(2).

So the grace period is real, it belongs to the vendors rather than to you, and it expires in about ten weeks. If you are currently checking whether your generation tool embeds provenance and finding that it does not, that is not necessarily non-compliance — it may be a system using its transition window. It also means the tooling landscape will shift again before December, and anything you verify today is worth re-verifying then.

On the compliance-demonstration side, the Commission and the AI Board have confirmed the Code of Practice on Transparency of AI-Generated Content as an adequate route for showing Article 50 conformity, and a standardised EU label is still in development. The label does not exist yet. Planning your interface around a badge that has not been published is premature.

C2PA is the mechanism, and it leaks

The technical standard carrying most of this is C2PA — Content Credentials — which attaches cryptographically signed metadata recording who signed a file, which tools were declared, and whether AI involvement was disclosed. The current specification is version 2.3, published in February 2026, and the coalition behind it now counts thousands of member organisations including Google, Microsoft, Adobe, Meta, OpenAI, Sony, the BBC and Amazon. Microsoft began writing C2PA metadata into Microsoft 365 content in February 2026. Google has watermarked billions of images with SynthID. TikTok has applied AI provenance labels at similar scale.

And it still falls apart in ordinary use, for a boring reason: metadata does not survive the internet. Re-encode a video, screenshot an image, run a file through a platform that strips EXIF on upload, and the signed manifest is gone. X, notably, does not enforce disclosure and strips provenance on upload — so a correctly credentialed asset can arrive on a major distribution surface with nothing attached to it at all.

This is why the industry has converged on two layers rather than one: C2PA manifests for detailed, verifiable creation metadata where the pipeline preserves them, and imperceptible watermarks such as SynthID as the fallback that survives re-encoding and screenshots. Neither alone is sufficient. A signed manifest that a platform deletes proves nothing, and a watermark with no manifest tells you something was generated but not by whom, when, or with what declared.

What a small operation should actually do

Four things, none of them expensive.

Find out what your tools emit. For every generation vendor in your pipeline, establish whether output carries C2PA credentials, an imperceptible watermark, both or neither — and write it down. This is a question for the vendor’s documentation, not a guess. It also changes when they migrate for the December deadline.

Label at the point of publication, not in a policy page. The disclosure duty attaches to what the audience sees. A line under the video does the job; a statement buried three clicks away does not.

Keep your own provenance records. Model, version, date, prompt, references, operator. If a credential gets stripped in transit — and it will — your own log is the only thing that reconstructs the history. This costs nothing at generation time and is unrecoverable afterwards.

Assume the tooling moves again before December 2. It will.
