On June 24, 2016, Betterment suspended trading for 2.5 hours, after the unexpected vote in favor of Brexit sent shockwaves of volatility through the financial markets. Subsequently, the firm was accused of not properly communicating the halt in trading with its customers. Following this incident, Betterment faced significant backlash against the protective move on social media, and Massachusetts Secretary of the Commonwealth William F. Galvin raised concerns over Betterment's actions, remarking that some customers could have been at a disadvantage because of the trading halt.
