Coinbase Chief Executive Officer Brian Armstrong said a targeting bug caused frequent prediction market push notifications on March 29 and apologized for the issue. He said the problem is being fixed and that Coinbase wants to give users more control over content preferences rather than broadly banning an entire category. The alerts were tied to Coinbase’s prediction market offering linked to Kalshi, which launched in January. The incident comes as U.S. prediction markets face broader regulatory pressure from several states and the Commodity Futures Trading Commission.
