AI authorship disclosure at major newspapers

The gist

Semafor finds NYT, WaPo, and WSJ all regularly publish AI guest columns

Major U.S. newspapers are publishing AI-generated guest columns in apparent violation of their own stated policies, raising direct questions about editorial enforcement and disclosure norms. Pew Research data show AI-associated writing patterns have spread substantially across the commercial web since ChatGPT's launch.

The full picture

Semafor analyzed every guest column published over the past month by the New York Times, Washington Post, and Wall Street Journal and found all three regularly publish AI-generated content. The NYT and WaPo explicitly prohibit AI-generated writing, yet appear in the findings alongside the WSJ. A separate Semafor analysis found AI signals in 50 of 310 guest columns at two newspapers with strict anti-AI policies.

The findings sit alongside a controversy sparked by the WSJ's publication of an op-ed by investor Stanley Druckenmiller that was described as clearly AI-generated. Druckenmiller acknowledged using AI but said the piece was not 100% AI-written and that he rejected many AI suggestions. WSJ opinion editor Paul Gigot defended publication, saying the key question is whether an op-ed reflects the author's genuine argument and standing. Zvi argued that using AI for the words without explicit attribution makes the author a 'prompter rather than author'. Philosophy & Public Affairs adopted a policy banning substantially AI-written papers, with lifetime bans for authors who lie about AI use.

A Pew Research Center analysis of nearly 500,000 English-language webpages found more than one-third of pages published after ChatGPT's November 2022 launch show signs of AI authorship. The study documented measurable stylistic shifts: em dashes appear roughly twice as frequently, Oxford comma usage has increased 63%, and words like 'delve,' 'interplay,' and 'testament' have more than doubled. By 2026, 9.4% of .com webpages show significant AI authorship signs, versus only 1% of .edu and 0.8% of .gov pages.

How it developed

Semafor on August 28 named the New York Times, Washington Post, and Wall Street Journal as outlets that regularly publish AI-generated guest columns, having analyzed every guest column the three ran over the past month; both the NYT and WaPo explicitly prohibit AI-generated writing.

Semafor concluded blanket bans will become unenforceable as AI detection grows less reliable. Pew's finding that one-third of post-ChatGPT webpages show AI authorship signs came from analyzing nearly 500,000 pages using a tool called Open Pangram.

Semafor names NYT, WaPo, and WSJ as all regularly publishing AI-generated guest columns; NYT and WaPo explicitly prohibit AI content

Semafor found AI signals in 50 of 310 guest columns at newspapers with explicit anti-AI policies, and a Pew Research study found roughly one-third of web pages published since ChatGPT launched show signs of AI authorship, expanding debate that began when the Wall Street Journal published an op-ed by investor Stanley Druckenmiller on August 25 that readers considered entirely AI-generated. Pew also recorded em dash usage roughly doubling and Oxford comma usage rising 63% across the web since 2023.
