PredictIt Alternatives for Trading US Political Markets

PredictIt has been trading US political markets longer than almost anyone else in the space, operating under a CFTC no-action letter, originally granted for academic research purposes, that comes with real strings attached: a narrow scope limited to political and policy contracts, and caps on how much any individual trader can put into a given market. Those aren't arbitrary product decisions PredictIt could simply remove if it wanted a bigger platform, they're the specific terms of the regulatory relief that lets it legally operate at all, which is exactly why looking for an alternative usually means looking for a different regulatory arrangement, not just a different brand.

Kalshi is the most direct comparison for a US-based political trader, because it's the other real, legal, dollar-denominated option, but under a fundamentally different structure: a full CFTC-regulated designated contract market rather than no-action relief, without PredictIt's position caps, and with a category list that extends well beyond politics into economics, weather, and more. For someone whose only complaint about PredictIt is the caps, Kalshi is very often the direct answer, with the caveat that it's a different exchange with its own account setup, not an extension of a PredictIt account.

For traders willing to look outside strictly US-regulated venues, Polymarket offers the scale and market breadth PredictIt was never structured to provide, at the cost of being crypto-native and, per its own terms of service, restricted for US persons in the first place, an awkward fit for exactly the audience PredictIt exists to serve. Limitless Exchange shares that same real-money, crypto-native structure on a smaller scale, worth knowing about but not a straightforward substitute for a US political trader for the same jurisdictional reason.

Manifold Markets is the one alternative on this list with no jurisdictional or capital-cap complications at all, because it uses play money rather than real currency and lets any user create a market on any topic, including plenty of political questions with no position limit and no approval process. What that removes is the thing that made PredictIt's prices worth watching in the first place: real capital at risk, which is a meaningful part of why a real-money market's price is treated as a credible probability estimate rather than a casual opinion poll.

There isn't a platform that offers PredictIt's exact combination of US legality, real dollar stakes, and unlimited position sizing, because that combination is precisely what the no-action letter doesn't allow. The honest way to think about a PredictIt alternative is to decide which piece of that combination matters least to you: give up the caps and go to Kalshi, give up US-regulated status and look at Polymarket, or give up real stakes entirely and use Manifold, rather than expecting to find PredictIt without the constraints that define what PredictIt actually is.
