Coinbase Global’s (COIN) stock traded in a tight range near $160 during the week of October 26, 2026, before a sharp post-earnings decline on October 30. The primary catalyst was the October 29 release of Q3 2026 results, which showed revenue of $1.22 billion (modest beat versus consensus) but a 35% year-over-year decline, alongside GAAP EPS of $2.51 driven largely by unrealized gains on crypto holdings. Adjusted EBITDA rose sequentially to $333 million, supported by expense discipline and growth in prediction markets and USDC balances, though transaction revenue remained soft amid lower crypto trading volumes. The company’s high beta to Bitcoin and broader digital-asset sentiment, combined with analyst price-target adjustments, contributed to elevated volatility and the subsequent sell-off below recent moving averages.
