Recent activist actions by Greta Thunberg in pro-Palestinian demonstrations have shaped trader views on the timing of any future arrest. On July 13, 2026, German police detained her and others during a sit-in blocking access to a defense manufacturer’s Berlin site, protesting arms supplies linked to the Gaza conflict. This followed her December 2025 arrest in London under the Terrorism Act for supporting related hunger strikers, after which she was released on bail. Ongoing involvement in flotilla efforts and protests against Israeli policies continues to draw law enforcement attention across multiple jurisdictions, with traders monitoring scheduled demonstrations, court dates tied to prior cases, and potential new actions through late 2026 for shifts in implied probabilities.
