All asset classes start with markets and exchanges. The next domino that falls is infrastructure.
Enter Delphi
( our story )
We are building the infrastructure that prediction markets need in order to mature into a real asset class.
Prediction markets are powerful because they reveal price, probability, and disagreement in real time. But today the market is fragmented across exchanges. Data is inconsistent, liquidity is split, and most participants only see a single venue instead of the full market picture.
Delphi aggregates real-time and historical market data from 10+ prediction market exchanges into a unified API, builds cross-exchange indices that benchmark real-world events, and powers Delphi News with reporting backed by market data instead of narrative. We are not building another exchange. We are building the layer that makes the ecosystem legible.

Our Team
We are Carnegie Mellon University AI, computer science, and machine learning majors and former prediction market traders building the data layer behind the prediction economy.
Data
We aggregate real-time and historical market data from 10+ prediction market exchanges, including Kalshi, Polymarket, and more, into a single unified API. Markets are matched and standardized across exchanges so users get the full picture, not just one venue's view.
Indices
We build cross-exchange indices that benchmark elections, macro outcomes, and geopolitical risks. It is a market-based benchmark layer for real-world events, designed so no single platform can distort the signal.
News
Delphi News delivers unbiased, non-partisan reporting backed by prediction market data. Instead of editorial opinion leading the story, the wisdom of the crowd helps separate signal from noise.
Delphi is building something different for the prediction economy. Follow the terminal, the research, and the signals as the infrastructure layer takes shape.
