Netflix's $587 Million InterPositive Acquisition Revealed in SEC Filing: What Ben Affleck's AI Startup Actually Does

Netflix’s acquisition of InterPositive, the artificial intelligence startup co-founded by actor and filmmaker Ben Affleck, has become much clearer after the streaming giant’s latest SEC filing revealed the value of the deal. While Netflix announced the acquisition in March 2026, it did not disclose the purchase price at the time.

A recently published quarterly filing has now confirmed that the company spent approximately $587 million in cash on an unnamed acquisition completed during that month.

Although the filing never identifies InterPositive or mentions Affleck by name, the timing aligns with Netflix’s previously announced purchase of the stealth AI company. The disclosure provides the first official indication of how much Netflix invested in technology that could reshape the way films and television shows are finished in post-production.

The acquisition also highlights Netflix’s growing investment in AI-assisted filmmaking, an area the company has increasingly discussed during earnings calls and industry events.

SEC Filing Reveals Netflix’s $587 Million Purchase

The figure appeared in the “Acquisitions” section of Netflix’s quarterly SEC filing, which states:

“In March 2026, the Company completed an acquisition which was accounted for as a business combination for a total purchase price of approximately $587 million, consisting of cash consideration.”

The filing does not identify the acquired company. However, multiple reports have linked the disclosure to InterPositive, which Netflix confirmed it acquired in March.

Before the filing became public, industry observers had speculated about the value of the transaction because InterPositive had operated almost entirely out of the spotlight. Despite launching in 2022, the company maintained a minimal public presence, with very few employees publicly listed and almost no online footprint before the acquisition announcement.

What InterPositive’s AI Technology Does

Unlike many generative AI platforms, InterPositive is not designed to create complete films from text prompts. Instead, the company’s technology focuses on streamlining post-production while keeping creative control in the hands of filmmakers.

According to previous comments from Ben Affleck, the platform was trained using footage recorded on controlled soundstages to understand visual continuity, lighting, editing patterns, and cinematic consistency.

Productions can then build project-specific AI models using their own authorized footage, allowing editors and visual-effects teams to relight scenes, replace backgrounds, fix continuity errors, remove unwanted objects, and generate missing shots more efficiently.

This creator-controlled approach has drawn attention at a time when Hollywood continues debating the role of artificial intelligence in filmmaking following the industry’s recent labor disputes over AI protections.

Why Netflix Believes the Investment Is Worth It

Netflix’s willingness to spend $587 million on a little-known company reflects its long-term production strategy rather than InterPositive’s size. The streaming service invests billions of dollars annually in original content, where post-production and visual effects can account for a significant portion of production costs.

During previous earnings discussions, Netflix co-CEO Ted Sarandos said that around 300 Netflix productions have already incorporated AI tools in some capacity, particularly during post-production. Speaking about the Tom Hanks-backed documentary The American Experiment, Sarandos said AI-assisted sequences were completed

“twice as quickly and at half the cost”

of traditional methods.

Those potential cost savings help explain why Netflix views AI-assisted post-production as a strategic investment rather than simply another technology acquisition.

While questions remain about Ben Affleck’s personal ownership stake in InterPositive, the SEC filing confirms one thing: Netflix made one of its biggest AI investments yet as it continues expanding technology across its global content pipeline.
