Two Roads Into Quantum Computing: Pure-Play Lottery Tickets vs. the Big-Tech Detour
Two Roads Into Quantum Computing: Pure-Play Lottery Tickets vs. the Big-Tech Detour
If you want exposure to quantum computing, you're really choosing between two roads: high-risk pure plays, or big-tech names that take quantum seriously. Let's put them side by side.
Road 1 — Higher risk: the pure quantum plays (lottery tickets)
The pure plays are IonQ, Rigetti, D-Wave, and Quantum Computing Inc. (QUBT). In a word, these are lottery tickets.
Huge upside if the technology arrives and they're the winner — near-total loss potential otherwise. Valuations right now are extreme and very much unproven. They're also heavily dilutive: pure plays regularly issue equity to fund R&D, so shareholders absorb dilution as the science advances.
Among the pure plays, IonQ tends to be flagged as the most commercially mature — the largest pure play by revenue, partnerships across all major clouds, and a clearer roadmap. Rigetti and D-Wave have much smaller revenue bases, and QUBT is the smallest and most speculative.
Road 2 — Lower risk: big tech that takes quantum seriously
The other road is big-tech names associated with quantum but not 100% quantum companies. Alphabet, Microsoft, IBM, Nvidia, and Amazon all have serious quantum efforts.
- Alphabet — its Willow chip is making breakthrough progress.
- IBM — on track for a fault-tolerant quantum computer by 2029.
- Nvidia — positioning itself as the essential bridge between quantum and classical computing through its Qiskit / CUDA-Q platform.
- Honeywell — holds majority ownership of Quantinuum, one of the leading trapped-ion firms.
The pitch is simple: you get quantum upside if it works, and you own profitable real businesses if it takes longer than expected.
Which road do institutions and billionaires take?
As multiple sources note, this big-tech road is exactly what large institutional investors are choosing. Billionaires have settled on Google parent Alphabet as their preferred quantum computing stock to own.
The comparison at a glance
| Dimension | Pure plays | Big-tech detour |
|---|---|---|
| Names | IonQ, Rigetti, D-Wave, QUBT | Alphabet, IBM, Nvidia, MS, Amazon |
| Upside | Very large (if winner) | Capped but durable |
| Downside | Near-total loss possible | Cushioned by core business |
| Dilution | Frequent equity raises | Not a factor |
| Who chooses it | Speculative retail | Institutions, billionaires |
The simplest option: a quantum ETF
In quantum too, the simplest option is an ETF. A quantum ETF holds a basket of quantum-exposed names, giving you exposure without betting on a single company surviving. If one company disappears, your whole portfolio doesn't go with it.
My conclusion: quantum is inherently a maybe-it-works-maybe-it-doesn't space, so I'd capture most of my exposure through big tech and an ETF, and add pure plays only in a size I can afford to lose. For treating quantum as a small sleeve within the whole portfolio, see my core-plus-sleeve portfolio piece.

Are the SpaceX, OpenAI, and Anthropic IPOs 50% Overvalued? Why I'm Wary of Hype Already Pumped in Private Markets
Some commentators say the SpaceX IPO is nearly 50% overvalued. My take: don't chase it. Meta (then Facebook) traded much lower a year after its glamorous IPO, and the hype usually peaks before the listing. I see more downside than upside risk across SpaceX, OpenAI, and Anthropic.
