What actually happened

Musk promised (Feb 9, 2026) that 'in the next few months' X would run rigorous security tests of X Chat AND open-source all the code (window closing mid-2026). That did not happen by the deadline: no whitepaper, no public source, no independent audit; the only Trail of Bits review of X Chat's protocol is dated October 2025, four months BEFORE this promise, so it cannot count. Musk has since restated the pledge with a new target — on July 24, 2026 he said 'Next month, every line of code touching the X system will be open source and third-party audited' (i.e. August 2026) — but as of August 13, 2026 the code is still not open-sourced. The goal has not been renounced, so the overdue clock keeps ticking. eSecurity Planet — X Chat still closed-source, no published audit (2026) ↗

Status: Missed · 138 days past due. Never happened.

By the June 30 window, X Chat had a limited encryption-protocol audit (Trail of Bits) but the full code was not open-sourced — the security-tests half partly happened, the open-source half did not.
