Broadcom beats SpaceX, Micron, SanDisk for long-term AI investors

Broadcom's appeal lies in the contrast between its consistent cash generation and the volatility inherent in its competitors' business models. While Micron and SanDisk have captured market attention with triple-digit stock gains, both are riding an exceptionally strong memory market driven partly by unusually high prices rather than volume growth. Sandisk's fiscal 2026 Q4 revenue growth, for instance, came two-thirds from higher prices rather than increased volumes—a dynamic that cannot persist indefinitely. Both memory makers have responded by signing multiyear customer agreements to stabilize revenues, but the risk of margin compression remains real once supply catches up with demand.

SpaceX, despite completing the largest U.S. IPO on record, faces a different challenge: capital intensity and execution risk. The company's $18.4 billion capex in a single period, with $15.8 billion directed toward its AI business, dwarfs Broadcom's spending. Broadcom benefits from being a fabless semiconductor designer (outsourcing fabrication) rather than a capital-intensive manufacturer or infrastructure builder. Its 143% year-over-year jump in AI semiconductor revenue and management's projection of $16 billion in Q3 show that the company is capturing significant share of the AI boom without requiring the same level of upfront investment.

Broadcom's valuation—20 times estimated fiscal 2027 earnings with 68% expected earnings per share growth—appears reasonable for a company combining rapid AI growth with strong free cash flow and low capital requirements. The company does carry concentration risk (five largest customers account for 45% of Q2 revenue) and financing exposure ($29 billion in potential lease-payment risk on one customer's AI racks over five years), but these are more manageable than the cyclical and capital risks facing Micron, SanDisk, and SpaceX.
