Background: Signal, owned by the Signal Foundation, currently uses end-to-end encryption for all messages, meaning only the sender and recipient can read message contents. The Signal Foundation cannot access the actual content of encrypted messages in the current version of their software.

Resolution Criteria This market will resolve YES if, before January 20, 2029, one of the listed Internet news sites reports that The Signal Foundation has provided the (decrypted) content of at least one user message to a US law enforcement agency. "Content" refers to the actual text, images, videos, or other media sent in messages, not to metadata such as user names, IP addresses, or timestamps.

Internet news sites: 404 Media, Ars Technica, Business Insider, The Markup, ProPublica, The Register, TechCrunch, The Verge.

• Update 9 Jan 2025 (From AI summary of comment) If the sites report on a backdoor but do not report that it was used to provide decrypted content to US law enforcement, the resolution will be No.
