At a glance

IonQ and Quantinuum announced their third-quarter 2026 results side by side. Both companies raised their revenue and annual outlooks, but their growth strategies and revenue models differ greatly. The article says the quantum industry has not yet settled on one direction.

Key points

1. 1

   IonQ's third-quarter revenue was $173.8 million, up 336% from a year earlier.

2. 2

   About 48% of this revenue came from SkyWater, a semiconductor foundry company IonQ acquired, so the growth figures include acquisition effects.

   Quantinuum's third-quarter revenue rose to $9.1 million, but its net loss grew to $118 million, more than double the previous year's loss.

4. 4

   Quantinuum said its profitability indicators improved, highlighting its error correction performance (technology that fixes errors that occur during calculations).

Why it matters

Whether quantum computers can become an industry that actually makes money is still open, and the two companies' different choices point to where it may go.
