Anthropic's Twitter handle is @anthropicAI.
Unresolvable The public record could not settle it.
Factual: Statements about the present or the past, checked against the record: did they hold up?
Said for an organisation they lead or work for; it counts on both records.
What would count as true or false
Judge as of 2022-03-04. True: on or around that date, the Twitter account with handle @anthropicAI (case-insensitive, as Twitter handles are) existed and was Anthropic's official account, as shown by Anthropic's website or official links pointing to it, account verification, or archived snapshots of the account identifying it as Anthropic. Mostly true: Anthropic's official account at that date had a trivially different spelling or styling (e.g. a capitalisation difference only) that still resolves to the same account. Mixed: not applicable in practice (single fact); use only if Anthropic had more than one official account and @anthropicAI was one, but not the primary, official account. Mostly false: @anthropicAI existed and was connected to Anthropic but was not its official handle at that date (e.g. it was created or claimed only after 2022-03-04, or was a secondary or unofficial account while the official account used a different handle). False: archived or official evidence shows Anthropic's official Twitter handle at that date was a different handle, or that @anthropicAI belonged to an unrelated party.

Reasoning
E1 (an independent 2026 guide) and E2/E3 (Anthropic's own 2025 page) show that @AnthropicAI was Anthropic's official X/Twitter account in 2025–2026. None of the evidence dates the account or shows that it existed and was Anthropic's official handle on or around 2022-03-04, which is what the criteria require. Nothing indicates a different handle at that date either, so the evidence does not settle the claim as of the judging date.
