Bank of America and Goldman Sachs have both upgraded Coinbase (COIN) stock to 'Buy', citing the company's strategic expansion and potential growth catalysts. Bank of America raised its price target for COIN to $340, a 41% increase from current levels, highlighting Coinbase's efforts to become an "everything exchange" by venturing into stock trading and prediction markets. The bank also anticipates the launch of a native token for Base, Coinbase's Ethereum layer two chain, as a significant growth driver. Goldman Sachs echoed this optimism, upgrading COIN from neutral to 'Buy' due to its positive outlook on crypto and Coinbase's diversification into new products like tokenization and prediction markets. COIN was trading above $240 at the last close, significantly below its all-time high, but the banks' upgrades reflect confidence in its long-term potential as a leader in the evolving crypto space.
