Yes, AllSides rates its own bias.
We recently analyzed how many sources from the left, center, and right appear in AllSides Headline Roundups. Our team carefully selects stories across the political spectrum every day, so that you can get the full picture and avoid being manipulated by bias.
For the second year, we’ve found AllSides displays an almost perfectly even split of left/center/right news sources, making us the internet’s most balanced news aggregator.
We have rated the bias of 2,400 media outlets and even social media influencers, and we believe in making our own biases transparent, too. (We even provide the bias of every team member here.)
In our Headline Roundups published between January and June 2025, AllSides displayed 36% sources on the left, 30% in the center, and 34% on the right.
We’ve also analyzed the bias of news aggregators like Yahoo! News, Google News, RealClearPolitics, Drudge Report, and White House Wire. While a few provide balance, most of them are heavily biased. AllSides is the most balanced of all of them.
In the first half of 2025, we curated 11% from outlets we rate Left, 25% Lean Left, 30% Center, 18% Lean Right, and 16% Right.
AllSides’ Headline Roundups offer a way to avoid harmful filter bubbles, echo chambers, and one-sided media manipulation. We provide a broad view to further our mission of helping people better understand the world — and each other.

How Does AllSides Compare to Competitors?
Most other news aggregators show a clear bias. Google News (Lean Left bias), for instance, curated 63% of news articles from liberal media outlets in 2023, an increase from 61% in 2022.
The White House Wire (Lean Right bias), which launched this year, curates content disproportionately from Right and Lean Right outlets – 57% of total content curation.
Yahoo News (Lean Left bias) disproportionately curates content from the left – 53% of its total content curation. Apple News curates 53% of articles from media outlets on the left, 25% from the Center, and just 1% from the right.

Consistency Over Time
In 2023, AllSides also established a near-perfect balance of content curation across Headline Roundups – outlets on the left/lean left at 33%, center at 33%, and right/lean right at 34%.
Since then, AllSides has made changes toward balance, covering Left outlets 3% more in 2025, while reducing content curation from Center outlets by the same percentage. This is in part because AP News shifted from Lean Left to Left, and around 12% of Headline Roundups didn't have Center representation (this may be because Center outlets were not covering a particular story, and because the Center category has shrunken overall in recent years.)
Despite AllSides’ shift to include more Left coverage by three percentage points, the difference between Left and Right media content curation has only shifted by one percentage point. As a result, AllSides remains largely consistent with its content curation from 2023, and maintains an approximately even distribution of content curation across Headline Roundups.
Moving Forward
Just as AllSides analyzes the bias of other news outlets and makes that transparent, we also apply the same standards to ourselves. We have the world’s most balanced news team, with all of our content undergoing reviews from team members on the left, center, and right. We put ourselves under the same scrutiny we apply to other outlets and aggregators, and hold ourselves accountable to ensure we provide the most balance possible.
