Coinbase stock plunged over 7% on Thursday due to a major data breach and weak Q1 earnings. Hackers bribed overseas contractors, accessing sensitive customer data, though no funds were stolen. The breach may cost Coinbase up to $400 million, triggering security concerns. Additionally, Q1 revenue of $2.03 billion missed expectations, with transaction revenue down 19% and trading volume down 10%, reflecting decreased retail activity. The company also faces SEC scrutiny over outdated user metrics. Combined, these factors rattled investor confidence, leading to the stock drop. As of May 17, 2025, Coinbase shares traded around $266, down sharply from earlier highs.
