The Pricing Primitive For Anything Numerical
Build markets on anything measurable, for apps, desks and traders
Design your own payoffs
Dynamic binary, ranges, or a shape you draw yourself. One book prices every one of them, and you set where, how wide, how far.
Built on functionSPACE
Prediction markets, trading games, research tools. See what teams are already building across domains on functionSPACE.
propSPACE
Free-to-play fantasy trading for the 2026 World Cup. Draft a forward, mid and defender, set your own line on their fantasy points, and stake a fresh $1,000 bankroll each knockout round. The sharpest calls climb the board.

Prediction markets as a living narrative graph: each node a market, each edge a plain-language reason two markets move together.

Express a belief in plain English, see it as a probability curve, and compare where you land versus verified pundit predictions.

Markets today answer one question: did it happen. A number that lands just outside the line pays the same as one that misses by a mile, and most quantities worth an opinion have no market at all. Precision pricing does exist. It gets built one desk at a time, for a short list of underlyings, and access is decided by who you are.
functionSPACE is built by mathematicians, physicists and engineers out of tech, crypto and AI. Shaping a payoff and pricing it is the hard part of this problem, and the team was assembled around that part.
One book sits under every surface, so a market opened anywhere is tradeable everywhere and nobody bootstraps liquidity twice. No desk sets your size, and settlement pays on the measured number rather than on someone's assessment of what you lost. The only limit is the depth in the market, which is the same for everyone and visible before you trade.
Open a market that did not exist and you are paid out of the commission on every trade it does, from every application that lists it. Flow reaches your book from all of them rather than only from you.
Any measurable quantity, priced by whoever holds a view on it.

Questions
What is functionSPACE?
functionSPACE is a purpose-built market structure for pricing beliefs on a numerical continuous range. Pricing, settlement and solvency sit in the mechanism itself, so a market opens without anyone quoting it, and every app built on it trades against the same shared depth.
What is functionSPACE used for?
Creating markets that could not exist before. Plenty of numbers are published, watched and argued over, and almost none of them have anywhere to trade. functionSPACE turns one into a market: you fix the range it will land in and put up the capital that starts it, and the mechanism prices and settles it from there. What that opens is a place to take a belief on the number with conviction and capital behind it.

What makes functionSPACE unique?
functionSPACE is a new financial primitive and a new way to trade: on where a number lands across a continuous range, rather than on a yes or no outcome. Traders express a belief anywhere on that range, in whatever payoff shape they choose, and can exit at any time or hold to settlement. The mechanism prices every view into a single market state and settles it.
Status: markets to date have run as play-money on an off-chain engine, and the on-chain contracts are a proof of concept.
