Can High Gate Fidelity Justify Buying Rigetti Stock Today?

Buying the stock today means paying for an engineering roadmap that runs years out, not for the hardware revenue the company books now.

Rigetti Computing (RGTI), a Nasdaq-listed maker of superconducting quantum computers, trades about 71% below its 52-week high, and it has gained 24.4% over the past month. What the price buys is an engineering roadmap, and how credible that roadmap looks is the whole of the case.

What 410 Times Sales Is Attached To

Even after a 39.2% fall over the past three months, against a 2.2% gain for the S&P 500, the stock trades at a price-to-sales ratio of 410.2 versus 3.3 for the index. That multiple sits on $13.4 million of revenue over the trailing twelve months, a base small enough that the ratio prices the future, not the present. Rigetti sells cloud access to its Cepheus-1-108Q system and on-premises Novera QPU hardware to national labs and universities.

The Revenue Line Is A Delivery Calendar

Second-quarter 2026 revenue reached $5.1 million from $1.8 million a year earlier, an increase the company attributes to on-premises Novera QPU sales. The $8.4 million C-DAC order for a 108-qubit system in India, which the company expects to recognize in the fourth quarter of 2026, is on its own close to two-thirds of the entire trailing-twelve-month revenue base. By the company’s own account revenue is shaped by the timing of system deliveries and government-funded projects.

Coherence Time, Not Qubit Count, Is The Constraint

Cepheus-1-108Q is assembled from 12 interconnected 9-qubit chiplets, and management says only three gate-based machines anywhere run above 100 qubits: this one, IBM’s and Google’s. Qubit count, though, is not where the difficulty sits. Coherence times of 25 to 30 microseconds are, on the company’s own account, the primary limit on two-qubit gate fidelity, and the chip design and materials work meant to double or triple them is expected to play out over several years. That timetable is the real clock on the 99.9% two-qubit fidelity that Rigetti’s roughly three-year, 1,000-qubit roadmap objective calls for.

What Pays For The Wait

The second quarter of 2026 produced a $28.1 million operating loss, wider than the $19.9 million a year earlier, as spending went into fabrication and refrigeration capacity. Funding that loss is $541.3 million of cash, equivalents and available-for-sale investments at the end of June 2026, down from $569 million three months earlier, and no debt at all. The Trefis High Quality Portfolio holds businesses with defensible balance sheets.

A Department of Commerce letter of intent for up to $100 million over three years could provide near-term runway—though it remains non-binding and carries dilution via a government equity stake. In the other direction, Rigetti plans to deploy up to $100 million into the U.K. across a longer, multi-year horizon under its ProQure program, meaning new government capital, helps fund an expanding global footprint rather than simply padding net cash.

Fidelity And A Signature Are The Two Receipts To Watch

The first receipt to look for is fidelity: management targets a median two-qubit gate fidelity of approximately 99.5% on Cepheus-1-108Q later in 2026, up from roughly 99.1%. That step is due well before the multi-year coherence work lands, so hitting it on schedule is the nearest test of whether the roadmap keeps its dates. The second is the Commerce letter turning into a signed agreement. A single hardware delivery may temporarily boost the revenue line, but longer-term commercial validation will depend on consistent roadmap execution and recurring system orders. Weighing a price like this against what a business is finally judged on is the job of a five-factor stock scorecard.

A Long Wait Rides On One Position

Holding one early-stage hardware name through a multi-year research cycle asks a great deal of a single position. A rules-based portfolio of quality businesses spreads that waiting across many outcomes. That portfolio has a track record of outpacing the three major indices – the S&P 500, S&P Mid-cap, and Russell 2000.
