Nvidia, Alphabet, AMD top Robinhood investor picks as AI chip boom accelerates

The prominence of Nvidia, Alphabet, and AMD on Robinhood's investor index reflects a decisive shift toward AI infrastructure as a retail investment theme. Nvidia's dominance emerged early in the data center boom that began in early 2023, and the company has sustained that lead through successive GPU generations. Its projection of $1 trillion（約160兆円） in orders through 2027 signals management confidence that demand remains robust as enterprises scale AI deployments; the imminent Vera Rubin rollout later this year will be a critical test of that trajectory.

Alphabet's inclusion among the top chip stocks marks a strategic turn. The company's success in designing and deploying TPUs for its own AI stack has proven valuable enough that it now sells them externally, diversifying revenue streams beyond advertising. This vertical integration—controlling both the chips and the software that runs on them—gives Alphabet multiple paths to monetize its data center investments and positions it differently from pure-play chip vendors.

AMD's presence reflects the reality that the AI chip market remains competitive and growing. Its 57% year-over-year data center sales growth in Q1 2026 demonstrates that Nvidia's leadership does not prevent other vendors from capturing meaningful share. Analyst forecasts of 55%–56% annual earnings growth for AMD over the next three to five years suggest sustained demand for alternatives. Together, these three stocks embody how retail investors are placing bets on the hardware layer of AI—a layer expected to grow substantially as enterprises integrate AI into production workloads.
