Most Popular Narrative: 17.4% Undervalued

Rigetti Computing last closed at $13.22 while the most followed narrative pegs fair value at $16.00. That gap is what the current debate revolves around.

Rigetti’s model is still early-stage and uneven. Revenue currently comes from system sales, cloud access, research and government-related contracts, and associated services, which means quarter-to-quarter results will remain lumpy. Q1 2026 is a good example, revenue improved sharply because of specific deliveries, not because Rigetti suddenly has a stable recurring-revenue engine.
