( why Delphi )

More market coverage

Delphi aggregates 10+ prediction market exchanges. Most competitors only expose a fraction of that market, which means less context and weaker signal formation.

More than raw data

Indices and insights sit on top of the API, so Delphi is not just a feed provider. It is an intelligence layer for pricing elections, macro outcomes, and geopolitical risk.

A media layer too

Delphi News turns market data into reporting. That makes the platform not only a source of data, but a source of interpretation rooted in crowd signal rather than editorial bias.
