Our Story

Disinformation has become a business. Today’s internet business models reward engagement above all else. These models monetise attention without considering the quality of the content garnering that attention, or the harm that may result. There is a robust and growing community of industry, policy, and civil society advocates pressing for reform of this ecosystem, they all need data to inform their actions.

The Global Disinformation Index was born out of this need for data, specifically the need for transparent, independent neutral disinformation risk ratings across the open web. GDI’s founders recognised early on that in order to disrupt the business model of disinformation, commercial companies, researchers and policymakers alike need access to independent ratings of news sites’ disinformation risk. These risk ratings are then used by advertising technology companies to ensure advertisers money and brands do not end up supporting high risk websites. Stakeholders also need strong and consistent leadership to help navigate the ever changing disinformation landscape.

Thus, GDI was established in 2018 as a not-for-profit entity built on the three pillars of neutrality, independence and transparency.


GDI is non-political, nonpartisan, and global in nature. We operate and partner in dozens of countries and with a variety of organisations, all united in combating disinformation and its harms.


GDI does not take funding from media companies or grants from technology companies. Our funding comes from a wide range of sources including governments, foundations and licencing our data to those who can use it to defund disinformation.


Many of our research methodologies and findings are made public, as are our funding sources. We also operate an open appeals process for sites that wish to contest their risk assessment.
