About Gigafact

What we do

Gigafact is a nonprofit network of nonpartisan local, regional, and expert newsrooms that fact-check and verify influential claims circulating online. Gigafact seeks to put a big dent in the flow of misinformation on social media, while amplifying the voice of trusted local and expert newsrooms.


We live in a world with rampant online misinformation. But we also live in a moment when the supply of factual and well-sourced knowledge has never been greater, if you know where and how to look. Gigafact creates new pathways to bring local, trusted authoritative sources flooding right to where consumers live on social media and other digital channels, to directly intercept unsupported claims before they have a chance to develop and travel.


Gigafact helps local newsrooms who join the network to implement a new standardized fact-checking editorial methodology via software tools, training, support and startup funding. Each week the newsrooms publish several short, sober and informative “fact briefs” that respond to influential claims and correct the record. Gigafact then assists in the amplification and distribution of those fact briefs to maximize the opportunity for the public to encounter them. This helps the newsrooms discover new audiences and growth opportunities. See one Gigafact newsroom talk about their experience here.

“In the years that we’ve been studying the rise of misinformation, we’ve realized there simply aren’t enough fact-checks to counter all the falsehoods. Gigafact is addressing this head-on with a wonderfully simple approach that should yield a dramatic increase in fact checks.”

–Bill Adair, Founder, PolitiFact; Knight Professor of Journalism and Public Policy, Duke University

“Gigafact is seeking to really accelerate the success we have had with the fact-checking journey so far, by growing the community, providing them essential tools, support and funding, and empowering local news and other credible sources to become fact-checkers. The time is right for this kind of vision, action and expansion.”

–Baybars Orsek, Fmr. Director, International Fact-Checking Network

“I spend a lot of time thinking about the future of news and journalism, and I love what Gigafact is trying to do: Bring high quality journalism into a system that quickly intercepts misinformation and disinformation before it spreads too far online. It’s a vitally needed service.”

–T. Christian Miller, two-time Pulitzer Prize winning investigative reporter

“Our research shows that we can improve students' ability to sort fact from fiction online by teaching them the strategies of professional fact checkers. Making fact-checks ubiquitously available, as Gigafact seeks to do, will be an invaluable resource for digital literacy.”

–Joel Breakstone, Director, Stanford History Education Group

“My research shows that correction of online claims, when done with evidence, quickly, and publicly, effectively reduces belief in misinformation, especially among the large audiences that social media facilitates. Generating more fact checks therefore empowers users, giving them accessible and accurate information they can use to correct one another, and creating downstream effects to reduce misperceptions in the broader public.”
