ANTW is trading at $25.57, up 5.53% after hours; no ANTW-specific catalyst has been confirmed.

  • ANTW closed the regular session at $24.23, down 3.77% on October 8; the after-hours gain reverses that decline.
  • Anthropic announced Claude Haiku 5.5 on October 7, but available reporting does not establish it caused the move.
  • A weaker Nasdaq and risk-off backdrop provide context but do not clearly explain ANTW’s after-hours rise.
