Bloomberg Bias Rating Moves From Lean Left to Center: 2026 AllSides Update

Is Bloomberg's bias liberal, conservative, or center?

After back-to-back AllSides Editorial Reviews and a Blind Bias Survey taken by 381 Americans, Bloomberg’s overall AllSides Media Bias Rating changed from Lean Left to Center — though the outlet sits close to the Lean Left border.

The new rating draws on three data points:

• June 2026 Editorial Review: Center (-0.93), from a panel of six expert bias reviewers, two each from the right, center and left
• May 2026 Editorial Review: Lean Left (-1.3), from a panel of six expert bias reviewers, two each from the right, center and left
• March 2026 Blind Bias Survey: Center (-0.39), rated blindly by Americans across the political spectrum

The weighted average of (-0.87) lands Bloomberg just inside the Center threshold.

When the May AllSides Editorial Review and the Blind Bias Survey of Americans together pointed toward a category change, AllSides reviewers expressed low confidence in the shift and agreed to conduct a follow-up review in June. That second review confirmed the overall move to Center.

AllSides has marked this final rating as low confidence, due to some indicators of Lean Left bias seen in Bloomberg’s news content.

Here’s what we found.

Bloomberg's Politics and Economy Desks Show Different Media Bias

The clearest driver of the move Center was a split based on news beats. Panelists found Bloomberg's politics coverage leaned institutionally liberal, while its economy and finance reporting skewed noticeably more conservative. Reviewers described stories like "US Job Openings Tick Up in Sign of Steady Labor Demand" as "straightforward, data-driven reporting" and characterized the outlet's economic coverage as "neutral to pro-capitalist."

Panelists also anchored it closer to the Lean Left/Center border for several other reasons:

• Lengthy context:
  • Stories included more background and context than reviewers expected, which made articles a bit more balanced even when the lede leaned left.
• Strong sourcing:
  • Bloomberg relies heavily on direct quotes from interviews or aggregating from other outlets and cites its sources rather than paraphrasing, which one panelist called "pretty balanced overall."
• Frequent digs at the left:
  • Bloomberg's coverage of New York Mayor Zohran Mamdani was more negative and included media bias types such as slant and viewpoint omission.

Examples of Center reporting during Bloomberg’s review period:

• House Passes Online Safety Bill as Senate Eyes Stricter Push
  • The story choice is balanced. Online safety, particularly for children, is a rare bipartisan issue.
• Trump Pauses Moroccan Fertilizer Duties to Aid Farm Economy
  • Balanced story choice and word choice with thorough background information. 
• Supreme Court Says Warrant Needed for Phone Location Data
  • The article contained balanced viewpoints: Both the in favor and the dissenting opinions with direct quotes, as well as legal context for the case. 
• Oil Erases Wartime Gains as More Tankers Transit Hormuz
  • This was a Center story choice.
• US and Iran Agree to Halt Attacking Each Other Ahead of Talks
  • The article was largely balanced when describing both sides of the war.

Media Bias Types Panelists Detected

The move to Center does not mean the panel found clean, bias-free reporting in Bloomberg. Panelists also noted a recurring pattern in which many articles opened with lean left ledes but grew more balanced deeper in the story, often tucking perspectives on the right well below the first few nut grafs. Additionally, stories that were more critical of New York Mayor Zohran Mamdani’s progressive policies pulled the outlet away from the Left category. One Center panelist said the outlet's treatment of Mamdani "would prevent them from ever becoming Left [rated]," since outlets most often rated Left produce more positive stories about Democratic Socialism.

Articles reviewed included but were not limited to:

• Supreme Court Will Consider Right to Own 'Assault Weapons
  • Slant: The lede described semi-automatic rifles as weapons having "repeatedly been used in mass killings," guiding the reader into perceiving these weapons are inherently created for this type of violence.
  • Viewpoint omission: "All the quotes in the piece are in favor of a ban — no quotes against it," one panelist said.
• Supreme Court Backs Birthright Citizenship in Blow to Trump
  • Word choice bias: "Blow to Trump" isn't a neutral description of a legal ruling.
• How Trump's Crackdown on H-1B Visas Imperils the American Dream.
  • Subjective qualifying adjectives: The story described the administration as expressing "outright hostility" toward some immigrants.
• Vornado CEO Appeals to Mamdani After Mayor's Griffin 'Blunder
  • Slant and viewpoint omission: The story omitted the perspective of Mamdani entirely and didn’t include any quotes from him. 
• Mamdani's Picks Sweep NYC Races as Anti-Establishment Anger Grows
  • Viewpoint placement: Skepticism toward Mamdani and the Democratic Socialists.
• Mamdani's New Pied-à-Terre Tax Leaves Wealthy With Few Loopholes
  • Opinion stated as fact: The lede claimed the super wealthy "might just have to pony up," which a panelist said "implies that the rich are not currently paying their fair share, which is a leftist position."
  • Story choice bias and viewpoint omission: The story bolstered experts describing billionaires' efforts to avoid the tax while omitting the perspective of those the tax would affect.

Americans Rate Bloomberg Center in Blind Bias Survey

In a March 2026 AllSides Blind Bias Survey, 381 Americans from across the political spectrum rated Bloomberg articles without knowing which outlet published them. Blind surveys prevent readers' bias toward a news source from influencing how they judge the content. On average, respondents rated Bloomberg Center (-0.39).

Bloomberg Isn't The Only Bias Change in 2026

Given the fluctuation between the two Editorial Reviews and the Blind Bias Survey, panelists assigned low to medium confidence to the new rating and agreed to review Bloomberg again in the future. 

Bloomberg is the second major outlet this year to move toward the Center on our bias scale.
