What is Timeline B?

Timeline B is a prediction-market fiction engine. It watches real prediction markets for the long shots — outcomes our universe prices at just a few percent — and files the news from the parallel universe where that tail actually fired. Each dispatch reports, in a deadpan newspaper voice, from the timeline where the unlikely came true.

The odds are real. The story is not. The market, its probability, and its resolution date come straight from public prediction markets; everything reported as having happened is fiction.

Is Timeline B real news?

No. Nothing here is a factual report and no event described on this site has happened. Every story is invented and AI-generated. We never fabricate quotes from real people; our experts and institutions — the Meridian Macro Institute, the Bureau of Vibes and Evals, the Institute of Applied Finishing — are themselves fictional and recurring. A real public figure may be the subject of a clearly-fictional event, but is never quoted and never depicted recognisably in an image.

Where do the probabilities come from?

From Polymarket, a public prediction market. Each story page prints the market question, the market-implied probability at the moment we read it, the date we read it, the resolution date and — where we recorded it — the total dollar volume matched on that market. Those figures are real and link back to the source market. How we read the market sets out exactly what is and is not a real number.

Who writes Timeline B?

Nobody real. Bylines are recurring fictional correspondents assigned deterministically by category, never generated — which is how we guarantee a real person’s name can never appear as an author. Every correspondent and institution is listed on the newsroom page. Stories are drafted by a language model, checked against a safety and quality gate, and anything touching politics is held for human review before it can publish.
