Alphabet (GOOGL), Amazon (AMZN), And IBM Emerge As Top Plays For AI And Quantum Exposure

Hyperscalers are no longer treating artificial intelligence infrastructure as a speculative future bet, committing hundreds of billions of dollars to meet surging demand.

Alphabet (GOOGL) has raised its 2026 capital spending guidance to between $195 billion and $205 billion, with AI infrastructure driving a significant portion of that investment.

Google Cloud revenues jumped 82% year over year in the second quarter of 2026, while the Cloud backlog reached a staggering $514 billion.

Quantum computing is advancing along a separate and considerably longer timeline, with governments and corporations increasing funding as practical applications inch closer to reality.

The U.S. government recently committed $300 million under the CHIPS and Science Act to D-Wave Quantum (QBTS), Rigetti Computing (RGTI), and Quantinuum, with each company receiving $100 million in R&D funding in exchange for minority government stakes.

Despite that announcement, both D-Wave and Rigetti remained more than 25% below their 2026 starting levels, highlighting the volatility that continues to plague pure-play quantum stocks.

PwC estimates global data-center capital spending will reach $31.6 trillion through 2050, with annual spending rising from roughly $800 billion in 2026 to $1.8 trillion by 2050.

McKinsey projects quantum-computing companies generated more than $1 billion in revenues in 2025, with that figure potentially rising to $4.4 billion by 2028, though return on investment remains difficult to quantify.

For investors seeking quantum exposure without the volatility, established hyperscalers offer a more grounded entry point backed by substantial current commercial revenues.

Amazon (AMZN) is seeing accelerating growth at AWS, where sales surged 37% year over year in the second quarter of 2026, its fastest growth in 18 quarters, pushing the business to a $169 billion annualized revenue run rate.

Amazon also disclosed its AI business surpassed a $25 billion annual revenue run rate, growing at a triple-digit rate, underscoring the depth of demand across its cloud platform.

Amazon recently entered a long-term partnership with Qualcomm under which it could purchase up to $60 billion of AI data-center chips and related products, further cementing its infrastructure position.

AWS also operates Amazon Braket, giving enterprise customers cloud access to multiple quantum-computing architectures and positioning Amazon at the intersection of AI and quantum development.

AMZN is projected to report full-year 2026 earnings growth of 82.2% on revenue growth of 15.7% and carries a Zacks Rank of 2, or Buy.

Alphabet is advancing its quantum-computing research through Google Quantum AI, which expanded into neutral-atom systems in 2026 and expects commercially relevant quantum computers by the end of the decade.

GOOGL is projected to report full-year 2026 earnings growth of 89.6% on revenue growth of 26% and currently carries a Zacks Rank of 3, or Hold.

IBM (IBM) offers the most direct quantum exposure of the three, while retaining a substantial enterprise AI and hybrid-cloud business anchored by Red Hat and its data platform.

In the second quarter of 2026, IBM software revenues increased 5%, with Hybrid Cloud revenues up 11% and Data revenues up 19%, demonstrating steady underlying demand across its enterprise portfolio.

IBM plans to invest more than $10 billion in quantum over the next five years, targeting quantum advantage in 2026 and a large-scale fault-tolerant quantum computer by 2029.

The company also announced a quantum innovation hub with Lockheed Martin in Switzerland, with an IBM Quantum System Two to be deployed at the Swiss National Supercomputing Centre, expanding its ecosystem across research, government, and industrial sectors.

IBM is projected to report full-year 2026 earnings growth of 6.4% on revenue growth of 4.3% and carries a Zacks Rank of 3, or Hold.
