Broadcom vs. Marvell: Which Custom AI Chip Stock Is the Better Buy?

Broadcom and Marvell are leading players in the custom AI chip market, with Broadcom expected to control 60% market share by 2027 versus Marvell's 20-25%. Broadcom demonstrates significantly faster growth with AI chip revenue projected to reach $230 billion by fiscal 2028 and EPS exceeding $30, compared to Marvell's more modest 45-50% annual growth guidance. Despite Marvell's 163% stock gain in 2026, Broadcom's cheaper valuation combined with superior growth trajectory makes it the more attractive investment opportunity.
