Arc settles in stablecoins with predictable USDC denominated fees and fast deterministic finality. That is what a prediction market actually needs: a fixed unit of account, cheap frequent price updates, and a settlement guarantee that does not move after the verdict.
A market that reprices hundreds of times a day cannot pay volatile gas in a volatile asset. Arc removes both variables, which is why prediction markets appear in its own design materials as a first class use case.
Built for Arc.
Built for markets.
Polymarct is native to Arc rather than ported onto it. The Arc category is not a marketing shelf, it is the feedback loop: every protocol milestone, supply threshold and network target becomes a priced question, and the price becomes the ecosystem's shared expectation.
