Palantir’s Quiet Takeover of Media’s Data Stack

The story. Adweek’s Mark Stenberg traces how Palantir — the data-analytics firm built for intelligence and defense work — has spent the past year signing deals across newsroom production, agency marketing and publisher audience monetization, without ever positioning itself as an ad-tech vendor.

01What happened

• Fox News Digital’s Newsroom platform, built on Palantir, now handles 95% of article production. Fox signed the deal in December 2025; president and editor-in-chief Porter Berry says none of that output is reader-facing AI-generated text — the platform automates the tasks around a human-written piece. “The forward-deployed engineer sits with the reporter who writes the piece and sees the editor who chooses the photo,” Berry said.
• Zeta Global’s Palantir-run identity graph covers 550 million opted-in individuals. Signed as a seven-year partnership in June 2025, it processes more than 7,500 computations per millisecond at peak season. CEO David Steinberg said the product beat rivals outright: “It was so good that we didn’t even go out and run a big bake-off.”
• Stagwell built a working agentic marketing system on Foundry in 16 weeks, running it across 1 billion touchpoints and 140 million U.S. households. Chairman and CEO Mark Penn dismissed reputational concerns about the defense-tech association: “We believe in Palantir and what it’s doing.” Chief AI officer John Kahan, formerly Microsoft’s chief data and analytics officer, framed the pitch as solving a market-wide failure: “The world spent probably $1 trillion trying to create structured data.”
• USA Today Co. signed a deal in August 2025 to analyze and monetize its audience data, with CEO Mike Reed describing the raw material in blunt terms: “Every visit, every session, and every moment of attention creates a signal.” Steinberg puts Palantir’s commercial client count above 600.
• The USA Today deal drew internal opposition. More than 800 employees across 31 unionized USA Today Co. newsrooms asked the company to end the partnership, citing reader trust, data security and editorial independence.

02What it means inside a GAM network

Palantir isn’t showing up as a DSP, SSP or measurement vendor, so it won’t appear on a header-bidding stack or an ads.txt file — but the USA Today deal makes clear it’s angling for a seat directly upstream of monetization, where first-party audience “signal” gets structured before it ever reaches an ad server. That’s new territory for an operator’s due-diligence checklist, not adjacent to it: a Foundry-style Ontology sitting on top of subscriber, session and behavioral data is functionally a CDP with far deeper defense-grade data-fusion capability, and any output it produces for “monetization” has to be checked against what GAM, AdX and MCM data-use terms allow a third party to touch before that signal becomes biddable. The Zeta and Stagwell deals show the same pattern one layer over on the buy side — an audience graph and an agentic marketing system built on infrastructure a publisher’s ad-ops team has no visibility into, which matters the moment that same graph starts informing programmatic bids against a publisher’s own inventory.

04The bottom line

Four deals — Fox News Digital’s production stack, Zeta’s identity graph, Stagwell’s agentic marketing system and USA Today’s audience monetization — show Palantir building the data infrastructure underneath both sides of the market at once, entering through newsroom operations and agency tooling rather than through anything that looks like traditional ad tech. For a GAM operator, the deal to watch isn’t the one at your own publication; it’s the one signed by a company like USA Today two rungs up the supply chain, quietly changing what “signal” means before it ever reaches your auction.
