Rumors that Jack Dorsey, co-founder of Twitter and chairman of Block, has joined AI company Anthropic have been debunked. This confusion arose from a series of humorous posts circulating on social media after Andrej Karpathy's recent announcement of his joining Anthropic.
On May 19, 2026, user @kanavtwt posted on X, "BREAKING: Jack Dorsey has joined Anthropic," alongside images of Dorsey and the Anthropic logo. This misleading claim sparked a wave of similar jokes, with notable figures such as Kanye West, Johnny Sins, and even historical personalities like Pope Leo humorously suggested to have joined the AI firm.
The joke format spread rapidly, as many users adapted the template with various names. Searches for any legitimate connection between Dorsey and Anthropic yielded no credible results, reinforcing the notion that the post was part of a viral meme rather than an accurate report.
Dorsey's actual affiliations remain with Block, a company he co-founded. Block has been active in the AI sector, notably announcing a collaboration in December 2025 with Anthropic and OpenAI to create the Agentic AI Foundation under the Linux Foundation. Despite this partnership, Dorsey has no legitimate ties to Anthropic.
This phenomenon highlights how quickly misinformation can spread in the digital age, especially regarding high-profile individuals. The trend of fake announcements not only reflects the current social media culture but also emphasizes the need for careful verification of news before sharing, particularly in the fast-evolving realm of AI and technology.
As AI firms continue to expand, the lines between fact and fiction can easily blur. Both individuals and companies must address these challenges to maintain trust and credibility in their communications. With the increasing interest in AI agents and the market's response to advancements, it's essential for stakeholders to ensure their messages are clear and accurate to prevent confusion and misinformation.
