Reddit Bullishness Spikes on DARPA Contract and Technical Breakthrough

The most discussed post on r/stocks detailed a bullish thesis citing three catalysts within 48 hours: the DARPA HARQ contract, Nvidia's release of open-source quantum AI models, and IonQ's demonstration of two independent quantum systems linked via photonic interconnect. The author noted the interconnect breakthrough matters because "the whole 'quantum advantage' thesis has always been bottlenecked by scale."

Another top post framed

$IONQ as a "too early until suddenly too late" stock, arguing the market rarely offers comfortable entries into potential category leaders. The post garnered 39 upvotes and 74 comments, reflecting deep engagement from retail investors weighing the risk-reward of early-stage quantum exposure.

Sector-Wide Momentum From Nvidia and S&P Global

The broader quantum sector rallied after Nvidia launched its Ising open model family for quantum AI applications. D-Wave Quantum surged 3.41% on volume nearly three times its average, while

$IONQ and Rigetti Computing also gained on the momentum.

An S&P Global report added fuel, projecting the quantum computing sector will grow from $2.5 billion in 2025 to nearly $9 billion in 2026. The report noted 76% of enterprises believe quantum computing will deliver material value within five years, with increased M&A activity and commercial deployment conversations marking 2026 as a breakout year.

Fundamentals and Analyst Outlook

Beyond the news catalysts, Reddit users highlighted

$IONQ's improving fundamentals: revenue tripled year-over-year to $130 million, with a $370 million backlog. The company reports earnings on May 6, and 12 analysts maintain a Strong Buy consensus with an average price target of approximately $67-69, well above the current ~$45 level.

The combination of technical breakthroughs, sector-wide tailwinds, and strong fundamentals has created a rare alignment that retail investors on r/stocks are actively debating — with many concluding that the risk of being early may be worth the potential reward.
