From a likely end-of-2026 base of roughly $65 billion, growth will likely decelerate into the first half of 2027. Assuming quarter-over-quarter expansion slows from the ~30% required in Q4 to roughly 15–20% in Q1 and Q2, net ARR lands near a median of $91.8 billion by June 2027, consistent with the unified consensus from an identically scoped question . The distribution remains wide to account for compounding uncertainties, with a 25th percentile of $76.3 billion. A severe bear scenario (p10 of 63.5) assumes the aforementioned lawsuits and price competition choke quarterly growth to the 10–15% range. Conversely, a sustained bull run driven by enterprise adoption and new agent capabilities could comfortably push ARR to $110.0 billion (p75). The extreme upper tail (p90 of 132.5) explicitly prices in resolution risk: if the resolving source defaults to reporting an Anthropic-style gross figure rather than OpenAI's strict net metric, it could inflate the recorded number by approximately 40%, generating a dramatic mechanical upside.
