The numbers come first. Paramount's $110 billion bid to acquire Warner Bros. Discovery has cleared the U.S. Department of Justice and passed review in all 68 jurisdictions worldwide where regulators examined it, according to a Fortune commentary by Syracuse University law professor Shubha Ghosh.
Despite that record, 12 state attorneys general are suing to block the deal. Their case rests on United States v. Philadelphia National Bank (PNB), a 1963 Supreme Court ruling that set a rule of thumb: if a merger produces roughly 30% of a market, courts may presume it harms competition, Ghosh writes.
The fight now turns on how that market is defined. According to the commentary, the states' complaint counts only wide-release theatrical movies and the basic cable bundle — and leaves out streaming, YouTube, sports rights, and everything else competing for viewers' evenings. Ghosh compares it to 'declaring someone the tallest person in the room after sending everyone taller out the door.'
The underlying viewing data cuts against the states' framing. YouTube is now the most-watched form of television in America, streaming makes up nearly the majority of all TV time, and Netflix and Amazon are buying up live sports rights, per the piece.
Ghosh also flags a structural problem with PNB itself: under certain interpretations of the ruling, courts are barred from weighing whether a merger might strengthen competition overall, even as plaintiffs draw narrow market lines to trigger the 30% presumption without proving actual consumer harm. He argues the 1963 case, at most, stands for the narrow idea that a merging firm can't excuse harm in one market by pointing to benefits in another — not that courts must ignore everything outside a cherry-picked market.
The central business question, in Ghosh's telling, is whether combining two legacy studios gives them the scale to compete with Netflix, Amazon, Apple and YouTube. He frames the choice bluntly: close the deal and the industry gets one studio with the incentive to invest and compete with the tech platforms; block it and two isolated companies are left struggling to keep up.
This is what regulatory overreach looks like when it runs on autopilot. A federal antitrust review and 68 sovereign jurisdictions reached the same conclusion, yet a coalition of state attorneys general is attempting to substitute a 63-year-old banking precedent — built for a world of storefront checking accounts — for an actual accounting of consumer harm in 2026.
Capital rewards clear rules, not arbitrary thresholds imported from a market that no longer resembles the one being regulated. If state litigators can gerrymander a market definition to manufacture a presumption of guilt, the losers are the shareholders who capitalized the deal and the American households already voting with their remote controls for streaming, YouTube and live sports over the cable bundle the states insist on measuring. The market has already decided where entertainment dollars go. The question is whether a courtroom stuck in 1963 will be allowed to overrule it.
