Coinbase is making a bigger play for retail investors by adding IPO share allocations to its expanding lineup of traditional investments. The crypto exchange will open the service to eligible U.S. customers this week with smart-ring maker Oura’s planned Nasdaq debut. According to a Monday announcement, eligible U.S. customers can request Oura shares at the IPO price through the Coinbase app before public trading begins this week. Coinbase said the move is “another tool that allows them to access more assets in a more complete financial ecosystem.”
