Sono Group is trading 75.31% up at $2.56 in pre-market, with no fresh company-specific announcement or clearly reported overnight catalyst identified.
- It closed September 17, 2026, at $1.46 after a 13.61% regular-session decline.
- The earlier Sports One combination remains the latest notable corporate development but predates the move and does not establish direct causation.
- Broader technology and risk-on sentiment may offer support, though the unusually large gain remains unexplained.
