PredictIt's per-contract limit explained
Why PredictIt caps positions at $850
PredictIt operates under a CFTC no-action letter that allows it to run real-money prediction markets without a full DCM licence: as long as it remains an academic research project run by Victoria University of Wellington. A key condition is the $850 per-contract cap, which limits individual exposure and keeps the scale within the scope of a research project rather than a commercial exchange.
For Kalshi's big political markets (US presidential election, Fed decisions), there's no position cap. Active traders who want to deploy more than $850 on any political market need to use Kalshi or the licensed Polymarket QCEX platform, not PredictIt.
Common questions
Is Manifold or PredictIt better for US politics? +
PredictIt for real-money political forecasting with actual USD stakes and a decade of track record. Manifold for learning, niche political questions, and free breadth.
What is PredictIt's $850 cap? +
$850 maximum per contract: a CFTC no-action exemption condition. PredictIt is an academic research project (Victoria University of Wellington) so positions are capped to keep it within that scope.
Does Manifold have real-money political markets? +
Manifold's currency is play-money Mana (no cash value) plus a sweepstakes cash layer (5% cashout, unavailable in DE, ID, MI, WA). Actual financial stakes are much smaller than PredictIt.
