Voters in two constituencies on Scotland’s east coast went to the polls in by-elections, alongside voters in Makerfield, Greater Manchester. Broadcasters said polling-day rules prevent them from reporting details of campaigning. Coverage in Thursday’s newspapers also highlighted Scotland football supporters in Boston ahead of the national team’s next World Cup match, with tabloid reports describing heavy celebrations in the city. Several papers also led with a US-Iran peace deal, including claims that the agreement waives oil sanctions in exchange for guarantees related to nuclear weapons and would return frozen funds to Iran.

Polymarket Data: $2.67M Volume as Leading 0.2–0.3% Bracket Hits 93.95% (+1.35pp, +60.6 in 24h)

On Polymarket, the ladder market “Peru Election 2nd Round: Margin of Victory? (0.1% brackets)” has drawn $2,674,509 in volume, with pricing heavily concentrated in a single narrow outcome. The “Fujimori 0.2–0.3%“ bracket sits at 93.95% Yes versus 6.05% No, while the next neighboring bracket “Fujimori 0.3–0.4%“ is priced at 4.6% Yes and 95.4% No. Farther out, “Fujimori 0.1–0.2%“ trades at 0.7% Yes / 99.3% No and “Fujimori 0–0.1%“ at 0.2% Yes / 99.8% No, underscoring how skewed positioning is toward one specific margin band rather than a broader distribution.

Watch whether liquidity migrates from the dominant “Fujimori 0.2–0.3%“ bracket into adjacent bands such as 0.1–0.2% or 0.3–0.4%, which would signal traders widening uncertainty around the final margin.
