Rigetti Computing vs. SoundHound AI: Which Technology Stock Is a Better Buy for 2027?

Rigetti Computing and SoundHound AI are two technology companies operating in the high-stakes world of emerging technology. Rigetti specializes in quantum computing, while SoundHound focuses on voice-enabled artificial intelligence. Despite their differences, both face significant hurdles to commercial success.

Rigetti builds superconducting quantum computers and offers access to its hardware through Quantum Cloud Services. The company primarily serves global enterprises and research clients, with nearly 90% of its revenue coming from U.S. government contracts. However, this customer concentration poses a risk, as shifts in federal research budgets or policy changes could impact the business. Rigetti's revenue decreased by 34.3% in the fiscal year ended December 2025, and the company reported a net loss of $216.2 million.

SoundHound AI, on the other hand, operates in the rapidly growing market for voice-enabled tech. It develops voice and agentic artificial intelligence software that powers natural conversational experiences across various industries. The company's revenue surged by 99.4% in the fiscal year ended December 2025, but it also reported a net loss of $14.0 million.

SoundHound's current ratio of 4.6x indicates a solid buffer for meeting short-term obligations, and the company is expected to reach adjusted EBITDA profitability by the second half of 2027.

When comparing the two, SoundHound AI appears to be a more attractive investment for 2027. While quantum computing shows promise, the industry is still struggling to reach commercial viability, and Rigetti's technology requires expensive cryogenic equipment. SoundHound, with its unprofitable but growing revenue, superior share price valuation, and consistent progress towards profitability, offers a more promising outlook for investors looking ahead to 2027.
