Reddit's AI Training Data vs Rigetti's 11.48% Quantum Rally

For AI researchers and ML engineers, Reddit represents one of the internet's richest structured datasets—recently monetized via AI training licenses to Alphabet—while Rigetti is a quantum computing play targeting workloads that classical AI infrastructure cannot handle. Reddit's $2.2B fiscal 2025 revenue shows the economic value of human-generated training data; Rigetti's 11.48% daily jump shows how quantum narratives can move on sentiment. This comparison exposes two very different next-infrastructure bets.

The key development is Motley Fool's August 22, 2026 head-to-head comparison asking whether Reddit (RDDT) or Rigetti Computing (RGTI) is the better high-growth stock for 2026. The piece frames a fundamental portfolio decision: an established social platform that has just reached profitability versus a speculative quantum-computing pure play with no demonstrated commercial scale. On the day the analysis appeared, Rigetti shares moved 11.48% while Reddit shares gained 1.98%, a gap that captures the volatility and sentiment-driven behavior of quantum names.

Revenue reached $2.2 billion, up 69.4% year over year, and the company swung to net income of $529.7 million, representing a 24.1% net margin.

Reddit's fiscal 2025 results mark a genuine inflection. Revenue reached $2.2 billion, up 69.4% year over year, and the company swung to net income of $529.7 million, representing a 24.1% net margin. The balance sheet is exceptionally clean: zero debt-to-equity and an 11.6x current ratio as of December 2025. Free cash flow came in at $684.2 million. However, stock-based compensation equaled 49.7% of operating cash flow, meaning a large portion of reported cash generation reflects non-cash add-backs rather than purely organic operating performance. Investors comparing Reddit's FCF yield or cash-based profitability should adjust for dilution.

The revenue mix introduces concentration risk. Reddit primarily monetizes through digital advertising, with its top ten advertisers accounting for approximately 21% of revenue in 2025. It also licenses data to Alphabet's Google for AI training, a fast-growing but concentrated line. Customer concentration is not fatal for a platform of Reddit's scale, but it means a shift in Alphabet's sourcing strategy or a downturn in a few advertiser verticals could materially affect near-term results. Still, Reddit's 45,000 active communities create a unique corpus of real-time human conversation, which is increasingly valuable as high-quality training data becomes scarce for large language models.

Rigetti, by contrast, offers no equivalent financial anchor in the article. It is described as developing advanced hardware for problems beyond classical computers. The absence of revenue, profitability, or liquidity figures in the source underscores the speculative nature of the investment. Quantum computing remains a high-risk, long-horizon technology bet. A one-day 11.48% move can be driven by research announcements, government funding news, or broad AI and quantum sentiment rather than company fundamentals. The article does not provide valuation multiples or technical milestones for Rigetti, which makes traditional underwriting impossible.
