The stupendous growth expectation for the quantum computing space is now mainstream. Going by a recent MarketsandMarkets forecast, this space is projected to witness a CAGR of 41.8% from 2026 to 2031, primarily demonstrating rising investments by both government and private sectors.
In this article, we have shortlisted three stocks, Amazon AMZN, Microsoft MSFT and IonQ IONQ, from technology and pure-play quantum firms for long-term gains within the quantum computing space, supported by substantial government investments and strategic partnerships.
McKinsey’s Quantum Technology Monitor 2025 highlights a sharp rise in public investment, signaling growing government confidence in quantum’s strategic and economic value. In 2024, global governments invested about $680 million in start-ups and announced $1.8 billion in broader quantum initiatives, from R&D to infrastructure. By early 2025, new commitments, led by Japan’s $7.4 billion and Spain’s $900 million, pushed total announced public funding beyond $10 billion. This surge marks a shift from research to real-world deployment, as policy-driven capital accelerates commercialization and strengthens the global race for quantum advantage.

Reports suggest that the Trump administration is crafting executive orders to help accelerate federal adoption of quantum technology and drive agencies to adopt post-quantum cryptography. If enacted, such directives might include procurement incentives and tighter timelines, which could accelerate commercialization and reduce risk for vendors. However, as of now, no such orders are entirely in force. Many proposed provisions remain in draft form and are subject to change.
A reauthorized National Quantum Initiative (NQI), with a proposed $2.7 billion budget through FY2029 and an extension to 2034, would further align R&D, grants and industry partnerships. Together, these steps could expand government contracts, attract talent and strengthen commercialization pathways.
For investors, this could mean faster revenue growth, increased M&A activity and higher valuations for leading players in the quantum ecosystem. While the start-up ecosystem remains a fertile ground for innovation, major technology companies such as Amazon, Google GOOGL, IBM IBM and Microsoft led many of 2024 and 2025’s key breakthroughs, signaling a new era for the industry. Publicly listed quantum firms like IonQ and Rigetti Computing are also positioned to gain from this momentum as government and corporate investment increasingly support scalable, commercially viable quantum systems.
