Quantum Computing Stocks: Why Pure-Plays Are Collapsing While Big Tech Sits Pretty

IonQ, Rigetti, and D-Wave were the darlings of 2024 — from penny stock levels to $30B+ combined valuation in a year. But here’s the problem: zero commercial breakthroughs, and the valuations are completely unhinged.

Let’s talk numbers:

• IonQ: Spent $2.5B on M&A since 2024, but generated less than $100M in revenue. Cash burn? Relentless. They’re basically funding themselves through constant stock dilution.
• Rigetti CEO sold millions worth at $12/share while admitting the company is still in R&D phase, “years away from meaningful revenue.”
• Price-to-Sales multiples: So absurd even dot-com bubble traders would cringe. For comparison, Microsoft and Amazon peaked at 31x and 51x P/S during the dot-com era. These quantum stocks? Still trading multiples of that.

So where’s the real quantum play? Alphabet (GOOG).

Here’s why: Alphabet isn’t betting on quantum as a standalone business — it’s vertically integrating it into its existing AI empire. They built Willow, their own quantum processor, and unlike the pure-plays, Alphabet has:

• A proven track record of monetizing moonshots (remember YouTube? Android?)
• DeepMind, one of the world’s most advanced AI research labs
• A $15.7T AI market to tap into (McKinsey estimates $1.3T could come from quantum apps)
• Actual revenue to fund R&D without constant dilution

A $10K investment in Alphabet’s IPO would be worth millions today. This is the quantum opportunity without the meme stock risk.

Bottom line: Pure-play quantum stocks are speculative R&D bets. Big tech is the safer way to own the quantum thesis while they actually build products people will use.
