In March 2026, Anthropic had three different leaks:

• a leaked memo criticizing the US Department of War

• leaked blogposts revealing the existence of "Claude Mythos"

• Claude Code source code (leaked via sourcemap)

Resolves YES if Anthropic has proprietary information leaked (for example, but necessarily not limited to, weights, source code, internal business messages, etc) between the creation of this market (on April 2, 2026) and April 30, 2026 at 11:59 PM UTC. Resolves NO otherwise.

EDIT: A leak is eligible for resolution if it's reported publicly by a mainstream media outlet, by Anthropic itself, or by any Anthropic employee, unless its factuality is cast into doubt by any of these three and is still in doubt at the end of the month.
