Despite the OFC 2026 partnership news and other recent developments such as the launch of its “Fab 1” chip facility and expanded foundry services, Quantum Computing’s 1 day share price return of 5.43% comes against a 30 day share price decline of 7.11% and a 90 day share price decline of 37.44%. At the same time, the 3 year total shareholder return remains very large, suggesting long term holders have already seen sizable gains as sentiment around future prospects has evolved.

Most Popular Narrative: 69% Undervalued

Quantum Computing’s most followed narrative pegs fair value at $23.67 compared with the last close of $7.34, a gap that rests on aggressive growth and margin assumptions.

Acceleration of AI and data center workloads is driving urgent demand for energy efficient, high speed computing. This is positioning QCi’s room temperature photonic quantum and reservoir computing platforms to scale from small research contracts to larger production deployments, which should expand revenue and support higher gross margins as volumes increase.

Want to see what kind of revenue ramp and margin shift would need to sit behind that fair value? The narrative leans on rapid scaling, richer unit economics and a future profit multiple that assumes material earnings power that is very different from today.

Result: Fair Value of $23.67 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, this depends on very small current revenue and heavy spending, and any slower adoption of AI or quantum solutions could quickly challenge the bullish setup.
