A Notified study published in June 2026 analyzed AI citations across 8,000 GlobeNewswire-distributed press releases, finding that 99.3% were cited by ChatGPT or Claude. The press releases achieved an average time to citation of just eight hours. Companies using Notified’s AI Press Release Optimizer generated 15% more citations on average than companies that did not. Well-structured release content was the strongest predictor of AI visibility, generating 2.6 times more citations on average. Owned content such as a blog or campaign page was twice as likely to be cited within the first 30 days when supported by a press release. The research highlights how public relations and investor relations teams can improve brand visibility through newswire distribution and well-structured content.
