Corrections & clarifications

Our methodology commits us to verifying claims against primary sources and refreshing comparisons when information changes. When we find a substantive factual error after publishing, we correct it and log it here with the date and what changed.

26 June 2026 - Kalshi vs Polymarket vs Manifold. Corrected the description of Kalshi's availability. The page previously implied Kalshi was open only to US residents. Kalshi expanded internationally in October 2025 and now accepts members in roughly 143 countries; however, the UK remains on its list of excluded jurisdictions, so UK residents still cannot open accounts. Sources: Kalshi Member Agreement / Help Centre; press coverage of the October 2025 international launch.

26 June 2026 - Vanguard vs InvestEngine. Corrected the date Vanguard introduced its £4-a-month minimum account fee. The page previously stated 2026; the fee took effect on 31 January 2025 (balances up to £32,000, total account fees capped at £375 a year). Source: Vanguard UK published fees and charges.

26 June 2026 - Trading 212 vs eToro. Corrected eToro's ISA fees. The page previously stated a £5 fee on every ISA withdrawal. The eToro Stocks and Shares ISA, powered by Moneyfarm, does not charge a withdrawal fee; its custody fee is capped at £45 a year. FX figures were clarified to roughly 0.50-0.70%. Source: eToro UK ISA fees page.
