Replacing Commercial Software with DIY AI Costs 11x More, RBC Report Finds

gleech · x · 2026-07-28

A 37-page report by RBC Capital analyst Rishi Jaluria models the cost of replacing commercial software with do-it-yourself AI tools, finding the expenses enormously prohibitive.

Building an AI replacement for Microsoft Office, for instance, could cost 11 times the license fee (an estimated $343,000). Beyond the initial build costs, the ultimate financial delta could stem from multi-million-dollar breaches caused by AI security holes. However, the author notes that the real threat might not be DIY solutions, but rather AI giants like OpenAI and Anthropic directly replacing commercial software with their own offerings.
