Netflix used AI to produce documentary footage at half the cost, content spending hits $20B

Netflix is deploying generative AI as a direct response to slowing revenue growth and rising content costs. Revenue growth has decelerated from 16% in Q1 2026 to 13% this quarter, with a 12% projection for Q3, prompting the stock to fall as much as 9% after hours despite in-line earnings. Content spending has accelerated faster than Netflix's historical average—rising to potentially $20 billion（約3.2兆円） this year, a 10% increase versus an 8% average over five years—driven partly by a new push into live programming (5% of content spend this year). Sarandos positioned AI as a way to unlock both speed and cost efficiency without replacing creatives. The company has already institutionalized the approach across 300 titles in post-production and is consolidating its virtual effects and production infrastructure, including the March 2026 acquisition of actor Ben Affleck's InterPositive for reportedly up to $600 million（約960億円）.

The bet carries real tension. The 2023 Hollywood labor strikes centered partly on AI protections and worker displacement—filmmaker Guillermo del Toro said he would "rather die" than use generative AI when promoting his Netflix-produced *Frankenstein* adaptation in October 2025. Yet Sarandos framed the investment carefully, arguing that "AI will give creatives better tools to bring their visions to life" and that "movies are being made by people who make movies." The cost savings from AI workflows could become increasingly important as Netflix faces competition not just from traditional rivals like Disney and HBO, but from gaming platforms, TikTok, and short-form video on phones—all competing for the same attention and engagement.
