243 days, then six days of changing words243 days, then six days
A dated timeline of Opaque Systems and Anthropic, as read on Monday 19 October 2026 and subject to change. A to scale axis runs 249 days from the Series B on 12 February 2026 to 19 October, with 243 days (derived) from the Series B to Opaque's post on 13 October and 112 days (derived) from the June launch of TRACE, Confidential MCP and Agent Manifest to that post. A magnified strip draws 13 to 19 October. Two cards set Opaque's post as the Internet Archive captured it at 17:46 UTC on 13 October, a new agreement with Anthropic that carries Opaque's work forward, against the live page read at 14:48 BST on 19 October, our team is joining Anthropic to carry Opaque's work forward, with the changed words marked and 6 days (derived) between them. Opaque's home page, first seen at 14:47 BST on 19 October, says OPAQUE Systems is winding down its operations. The word acquired is on none of Opaque's pages read; SecurityWeek says acquired and Constellation Research says licenses and brings on some of the team. Anthropic's newsroom list, read at 14:52 BST, has no entry mentioning Opaque among ten items dated 1 to 18 October. Four open projects are named: the Agent Governance Toolkit is a Microsoft repository with 6,444 of the 6,528 stars across the four (98.7 per cent, derived), and the other three sit in AgenTrust, which says it is independent and that Opaque sponsored it until October 2026. Price, closing, headcount, customer plans, any Anthropic statement and when the wording changed are not stated. Hover, tap or focus any item for the exact words and the source.
13 dated entries, in order, 12 February to 19 October 2026 (as read on 19 October)

The Internet Archive's only October capture of the home page that returned a page, taken at 00:35 UTC on 10 October, does not contain the words winding down (counted by this site).

The same post, read live, says Opaque's team is joining Anthropic to carry its work forward. Its date line is still 13 October 2026, and the page carries no note that it was edited. The capture of 13 October said a new agreement instead. When the wording changed is not stated: it is only bracketed by the capture at 17:46 UTC on 13 October and this reading. SecurityWeek, at 08:45 BST, already describes the post as saying the team is joining (secondary).
Opaque's post, live page, read 19 October 2026, 14:48 BST: “Today, we're proud to share that our team is joining Anthropic to carry OPAQUE's work forward.” The page's date line reads 13 October 2026. No edit note: no word updated, edited or revised appears on it (counted by this site).

This site's note on Anthropic's newsroom list, read in a browser, 19 October 2026, 14:52 BST: “No entry from 1 to 18 October mentions Opaque.” This site's own note on its reading, not Anthropic's words.

Not stated: any Anthropic statement about Opaque, on its newsroom or on any page read.
13 to 19 Oct, magnified, 6 days, to scale. On the 249 day axis these entries sit too close to tell apart, so the strip draws 13 to 19 October to scale, one column for each date. Entries on the same date are stacked, in time order, each with its time. 13 to 19 October is 6 days (derived).
