Atlassian reported fourth-quarter results on 6 August showing cloud revenue up 31% to $1,213m and total revenue up 28% to $1,766m. The stock rose more than 30%. Subscription ARR reached $6,606m, up 23%, with remaining performance obligations up 44% to $4.8bn.
The AI metric is a protocol, not a chatbot
The number the market seized on: Atlassian's MCP server and Teamwork Graph CLI together passed 1 million monthly active users, more than doubling in a single quarter, with MCP calls up more than 400% sequentially. That is machine access to Atlassian's data — external agents reading Jira and Confluence — not humans using an assistant.
What Rovo actually reports
Rovo is used by over 80% of the Fortune 500, and Rovo-assisted actions grew more than 50% sequentially. Both are adoption-breadth figures rather than revenue. Atlassian discloses no AI revenue line at all, so none of the 28% growth is attributable to Rovo on the record.
The guidance cuts the other way
FY2027 is guided to roughly 13% total revenue growth, about 25.5% Q1 cloud growth and about 18% subscription ARR growth — down from 23% in FY2026. A 30% share move on a quarter that beats and an outlook that decelerates is the market pricing the reacceleration, not the forecast.
Why it reads as a signal anyway
Cloud growth had been guided near 23% and printed 31%. Whatever is driving that, the fastest-growing usage Atlassian can point to is agents connecting through MCP — the least chat-like thing in the portfolio.
