Alphabet has emerged as the leading quantum computing stock for the next five years, driven by its in-house development of the Willow quantum chip. In late 2024 the company announced that Willow’s error rates decline exponentially as qubit counts scale, and in November 2025 it demonstrated a benchmarked algorithm on Willow that outperformed the most powerful classical supercomputers. These milestones underline Alphabet’s ability to advance qubit stability and coherence time—key hurdles in quantum hardware—and position it to capture early commercial applications in materials science and cryptography.

Despite its quantum ambitions, Alphabet’s established advertising and cloud platforms continue to generate robust cash flows. In Q4 2025, Google Search and YouTube advertising drove $62 billion in revenue, while Google Cloud posted $25 billion, growing 27% year-over-year. With gross margins of roughly 60% across the combined business, the firm trades at approximately 29x forward earnings—below the 5-year average of 33x—offering investors a stable entry point into both near-term cash generation and long-term quantum upside.

Alphabet’s AI strategy extends beyond infrastructure to consumer-facing products through its Gemini chatbot. Analytics firm Similarweb reports Gemini’s share of global AI chatbot queries rose from 5% at the start of 2025 to 18% by year-end, and internal data indicates it now exceeds 21% market share. This shift was catalyzed by the November 2025 launch of Gemini 3 and by partnerships integrating Gemini into Siri on millions of Apple devices. As a result, Alphabet is positioned to capture both incremental cloud compute sales and higher-margin AI services revenue in 2026 and beyond.
