IonQ (IONQ) drew fresh attention after reports highlighted its role alongside Alphabet and Nvidia in the push toward commercially viable quantum computing by 2030. This underscored its position as a pure play quantum computing stock.

Against this backdrop, IonQ’s share price, which last closed at US$32.84, has fallen 33.4% over the past 30 days and 29.8% year to date. However, the 3 year total shareholder return of about 70.6% and 5 year total shareholder return of roughly 230.7% indicate that the longer term story has so far been much stronger than recent momentum.

If this quantum computing story has your attention, it can be useful to compare IonQ with a wider group of pure play peers by checking out 26 quantum computing stocks.

After IonQ’s sharp pullback and with analyst targets and intrinsic value estimates spread far above and below the current US$32.84 share price, where does fair value plausibly sit within that range?

Most Popular Narrative: 31.6% Undervalued

Compared with IonQ’s last close at $32.84, the most followed narrative points to a fair value of $48.00, implying a sizeable valuation gap.

The first driver is still revenue scale. IonQ is increasingly separating itself from peers through actual top-line growth. If it lands in the $260 to $270 million range this year and shows similar momentum into 2027, investors may continue to treat it as the category leader.

Want to see what justifies that higher fair value for IonQ? The narrative leans on aggressive revenue compounding, expanding platform breadth, and a premium future earnings multiple that is anything but conservative.

Result: Fair Value of $48.00 (UNDERVALUED)

However, this IonQ narrative could be knocked off course if trapped ion technology loses favor, or if ongoing losses make its current valuation look stretched.

Another View: IonQ Through a P/E Lens

While the popular IonQ narrative points to a fair value of $48.00, the current P/E of 39.7x tells a different story. It sits below the wider Tech industry at 41.9x, roughly in line with peers at 40x, but well above a fair ratio of 16.5x. This spread implies meaningful valuation risk if sentiment cools.

This gap suggests the market already factors in a lot of future success. The key question is whether you think IonQ’s execution can keep investors comfortable with such a premium multiple over time.
