The Trump administration just announced $2 billion in CHIPS Act grants for nine quantum computing companies. Quantum stocks surged across the board. Here are three ways to play the sector, from pure-play speculative to blue-chip infrastructure, and what the alternative data says about each one.
Quantum computing stocks rallied hard today after The Wall Street Journal reported that the Commerce Department plans to award $2 billion in grants to nine companies in the sector. IBM is set to receive $1 billion to build America's first purpose-built quantum foundry. GlobalFoundries gets $375 million. D-Wave, Rigetti, and Infleqtion are each expected to receive $100 million. The government is taking equity stakes in all nine companies, a structure it previously used for strategic investments in mining and materials.
The grants are funded through the CHIPS and Science Act, and they signal that Washington views quantum computing as a national security priority on par with semiconductor manufacturing and AI infrastructure. For investors, the question is which companies are positioned to benefit beyond today's momentum trade.
We looked at three stocks that give exposure to the quantum computing theme from different angles. A mega-cap with the resources to lead the research. A pure-play that's riding the hype. And a profitable semiconductor equipment maker that builds the hardware quantum systems need to function.

Google doesn't rally on quantum news the way a pure-play does. It's up less than 1% today while D-Wave and Rigetti are up 28%. But Alphabet is arguably the company best positioned to actually commercialize quantum computing at scale. Its Willow chip demonstrated error correction below the fault-tolerance threshold, a milestone that the rest of the industry is still trying to replicate. Google has the research budget, the cloud infrastructure (Google Cloud), and the AI expertise to integrate quantum into real-world applications.
The alternative data tells us Google is investing heavily right now. Job postings nearly doubled from 3,204 in December to 6,656 today. That's a 108% increase in five months, and it's not seasonal. The hiring surge started in February and has sustained through May. Headcount ,according to LinkedIn headcount, grew from 306,000 in June 2025 to 342,505 today, adding roughly 36,000 employees in under a year.
AltIndex Job Postings Data
Revenue hit $109.9 billion in Q1 2026, up 21.8% year-over-year, with a 37.9% profit margin. 81% of employees report a positive business outlook, among the highest of any large-cap tech company. Congressional trading activity is mixed: Ro Khanna bought $33,000 worth of shares in March but sold $8,000 in April. John Fetterman bought $8,000 in March. 29 of 38 analysts rate it a buy.
Our AI Score of 54 places it in hold territory, weighed down by a weak audience sub-score, but the fundamentals tell a different story. If quantum computing delivers on its promise over the next five years, Google is likely to be one of the three or four companies that matter. The stock won't double overnight on a CHIPS Act headline, but the foundation is being built.

QUBT surged 19.4% today on the $2 billion CHIPS Act news. Here's the thing retail investors need to know: Quantum Computing Inc was not one of the nine companies receiving funding. The stock rallied purely on sector momentum. The companies that actually received grants are IBM, GlobalFoundries, D-Wave, Rigetti, Infleqtion, and Diraq.
That doesn't mean QUBT is sitting on the sidelines. The company reported $3.7 million in Q1 2026 revenue, up from just $39,000 a year ago. Headcount grew 45% in five months, from 83 to 120 employees. The company acquired QPhoton in 2023 for its thin-film lithium niobate (TFLN) photonics platform, and recent acquisitions are starting to generate real, if small, revenue.
But this stock moves on sentiment, not fundamentals. The Stocktwits data tells the story clearly. Last week (W20), Stocktwits mentions spiked to 942 per day, up from a baseline of roughly 100-130. Reddit mentions surged to 12 per day in the same week, up from under 1. The price followed: QUBT ran from $8 to over $11 in a matter of days. This is a classic social momentum pattern, and the chart below shows how tightly Stocktwits activity correlates with price moves.

The risks are significant. Job postings dropped 47% month-over-month, from about 10 to 6. Insider Christopher Bruce Roberts sold $614,000 worth of shares in March. The short ratio of 50 days is extremely high, meaning there's heavy short interest that could cause violent moves in both directions. And with a $2.2 billion market cap on $3.7 million in quarterly revenue, you're paying over 148x annualized sales for a company that's still losing money.
QUBT is the high-risk, high-reward play. If the quantum sector stays hot, the momentum could carry it further. If sentiment shifts, the short ratio means the unwind could be severe.

Teradyne is the picks-and-shovels play on quantum computing. The company makes automated test equipment (ATE) used to verify the performance of semiconductors, including the specialized chips that quantum systems rely on. When companies like IBM, Google, or Rigetti build quantum processors, those chips need to be tested. Teradyne builds the machines that do the testing.
The financial story here is strong and accelerating. Q1 2026 revenue hit $1.28 billion, up 87% year-over-year, and EPS of $2.56 beat estimates by $0.44. That's nearly double the revenue from a year ago. And this isn't just quantum. Teradyne benefits from the broader semiconductor upcycle driven by AI, 5G, and automotive chips. Quantum is an incremental tailwind that adds to the total addressable market.
Teradyne Quarterly Revenue (Company Filings)
The alternative data is consistently bullish. Job postings more than doubled from 219 in December to 473 in May. Headcount grew 6.2% in five months. Web traffic surged 46% from 166,000 to 243,000 monthly visits. 77% of employees report a positive business outlook, which is strong for a semiconductor equipment company and suggests internal confidence in the growth trajectory.
TER has been trending on Reddit too. In early February (W06), both Reddit and Stocktwits mentions spiked dramatically, with Stocktwits hitting 179 daily mentions versus a normal baseline of 10-15. That coincided with the Q4 earnings beat and the stock's breakout above $300. Social attention has remained elevated since, with another Stocktwits spike in late April (121 mentions in W18). Unlike QUBT, the social buzz for TER is driven by fundamental catalysts, not pure speculation.
Our AI Score of 66 places Teradyne in buy territory. Five of nine analysts rate it a buy. The PE of 59x is elevated, but you're paying for 87% revenue growth and a company positioned at the infrastructure layer of multiple secular trends. If quantum computing scales, Teradyne's testing equipment becomes essential. If it doesn't, the AI and semiconductor business sustains the growth on its own.
Alphabet is the safe bet with a $4.7 trillion market cap, 38% profit margins, and a quantum research program funded by Google Cloud revenue. QUBT is the speculative play: 120 employees, $3.7 million in revenue, and a stock that moves 20% on sector headlines. Teradyne is the middle ground: a profitable company with real revenue growth and exposure to quantum through its testing equipment business.
What the alternative data adds to this picture is the operational momentum beneath the stock price. Teradyne's job postings doubled in five months. Google's headcount grew by 36,000 employees in a year. QUBT's team grew 45% but its job postings just fell by half. These signals don't predict tomorrow's price, but they reveal which companies are actually building versus which ones are riding the wave.
