On the board right now

The first category is Frontier: the wildest things people believe, quoted live by SiFi.

All markets
A hooded figure plants a banner with a four-pointed star on a ridge, as a bank's columns crumble behind him and a glowing city rises ahead.

The old order
is falling.

This year the tech industry built models that write code, run research and ship products. DeFi's biggest launch was an index tracking vault that can't get hacked, and even that is up for debate.

DeFi has been taken over by people with no idea what good engineering can produce. It's time to rip the band-aid off and start again.

An institution with an idea

Funds LPs who invest in it, and has banks build custom swaps to represent it.

You, with the same idea

Elsewhere: a $1,000 prediction market. On SiFi: a market quoted the moment you type it.

Market makers won't make the markets you want liquid. SiFi will. And when enough people believe in an idea, SiFi funds projects related to it into existence.

This is defiance.

SiMM, not AMM.

Tails, scalar, distribution and split markets all fail for the same reason: nobody quotes them. Fancy curves don't fix that. A market maker that reads the world does.

Why it works here

  • Nobody else will quote itThe biggest makers in Polymarket tails pull low five figures a month. No serious quant spends a team on that.
  • Curves don't know anythingA curve doesn't know the news, the flow or the odds. SiFi does.
  • We are the venueLatency and spreads across every market are ours to set.

We start with the craziest.

Global markets are the size of expressed beliefs. Unexpressed beliefs are bigger. Categories open one at a time, each feeding SiFi more flow.
