[Coinbase Faces Strong Opposition from Users Over Promoting Prediction Markets, CEO Apologizes for Bug] According to Cointelegraph, Coinbase faced strong backlash from users after sending out numerous notifications about the March Madness basketball event prediction market. Users accused the platform of indirectly encouraging gambling. The prediction market feature, developed in collaboration with Kalshi, was launched in January this year, and the notifications were criticized as overly intrusive, sparking trust issues within the industry. Coinbase CEO Brian Armstrong responded by stating that the notification issue was due to a bug, which is now being addressed, and apologized to users. Meanwhile, prediction markets in the U.S. are facing state-level regulatory lawsuits and federal jurisdiction disputes, with Congress also advancing related legislation and a ban on trading by lawmakers.
