Short answer: Bloomberg News is owned by Bloomberg L.P., and Bloomberg L.P. is owned — to the tune of roughly 88% — by one man, Michael Bloomberg, the billionaire former mayor of New York. The rest sits with co-founders Thomas Secunda (about 4%), Duncan MacMillan and Charles Zegar (about 1% each) and a group of longtime employees. So the interesting question isn't really whether Bloomberg leans left or right. It's what happens to a newsroom when its owner is also a political figure — and has a written rule about not being investigated. * Michael Bloomberg founded the company in 1981 on the back of the Bloomberg Terminal, the financial-data machine that still prints most of the money; the news division came later and largely exists to feed those terminals with journalism. He is not a Trump man — he served as New York's mayor first as a Republican, then as an independent, then registered as a Democrat, and in 2020 he ran for the Democratic presidential nomination, pouring around $1 billion of his own fortune into the campaign. If you're asking "is Bloomberg pro-Trump," the owner is one of the largest Democratic donors in the country. * But the real conflict isn't partisan, it's structural — and Bloomberg News says so out loud. It has a standing policy of not investigating Michael Bloomberg, his family, or his foundation. When he entered the 2020 race, editor-in-chief John Micklethwait extended that shield: in a November 2019 memo he told staff the newsroom would not run investigations of Bloomberg's Democratic rivals either, because "we cannot treat Mike's Democratic competitors differently from him" — while making clear it would keep investigating the Trump administration. * That policy did exactly what you'd expect: it handed critics a gift. Reporters and press-freedom groups pointed out that promising to investigate one party's nominee but not the other's is not neutrality, whatever the stated logic behind it. Bloomberg said it would republish or summarize other outlets' investigations of its owner rather than bury them — but the asymmetry was baked in for the length of the campaign. * There's a long-term twist in the ownership, too. Michael Bloomberg has pledged to leave his controlling stake to Bloomberg Philanthropies, his charitable arm, so that one day the company's profits flow to his foundation rather than to heirs. It's a genuinely unusual succession plan — but it also means the outlet's future is tied to the priorities of a single donor's philanthropy rather than a public market or a family dynasty. * So, biased? Not in the tidy left-right way the search box implies. Bloomberg News does careful, market-moving financial journalism, and on most days its business coverage is about as straight as it gets. Its bias risk lives in one specific place: the wall around the man who owns it. On our least-biased-news ranking we care less about a newsroom's vibe than about who signs the checks — and here, one billionaire signs nearly all of them.
