Best prediction markets for politics and elections

Every scored platform that lists political markets — elections, nominations, legislation, approval ratings — ranked by Editor Score.

Political contracts are where resolution rules matter most. “Who wins” sounds simple until a result is contested, certified late or overturned, so each review states what a platform settles on and who decides when the answer is disputed.

2. Interactive Brokers ForecastTrader

Forecast contracts listed on ForecastEx, a CFTC-designated contract market

5.9Prelim

Strengths

  • A published specification for every contract — we checked roughly 11,470 live instruments and found none missing
  • The only venue we cover with a real, dated, public record of contested settlements: 439 notices including eight data overrides
  • A separate disciplinary log, which includes a filing against Interactive Brokers itself
  • Interest paid on open position value, which no other venue here offers
  • Contract terms settle the revision question explicitly rather than leaving it to be argued

Watch out

  • The exchange is a wholly owned subsidiary of the broker’s parent, so the broker owns the venue that decides
  • Determinations are “final and not subject to review”
  • The exchange’s own committee decides whether a dispute may go to arbitration, and that decision is final too
  • Binary contracts have been settled non-binary at 50/50, which the customer-facing FAQ does not prepare anyone for
  • Rule 415 assigns a data-error decision to a body the rulebook never defines
  • Economic and political contracts only — not a sports venue

3. Crypto.com Prediction Markets

USD-settled event contracts in the Crypto.com app, listed by CDNA

5.8Prelim

Strengths

  • Contract specifications are filed with the CFTC, so they need no account to read and cannot be quietly edited
  • The elections contract names fourteen source agencies individually rather than gesturing at “official sources”
  • The delay contingency is written out: settlement waits until the source releases the outcome
  • Sits inside an app many US readers already have, with no separate account to open

Watch out

  • We could not locate CDNA on the CFTC’s own Designated Contract Market register, so no licence is claimed on this page
  • The CDNA rulebook, which the filings defer to for jurisdiction and enforcement, could not be retrieved
  • The fourteen source agencies apply “as determined by the Exchange”, so the authoritative outlet is chosen after the fact
  • No public record of past determinations was found
  • Available in the United States only

4. PredictIt

Political event contracts run under CFTC no-action relief

3.9Prelim

Strengths

  • Every market’s settlement rules are readable through a public API with no account — better disclosure than several regulated venues
  • The longest continuous price history in US political prediction markets
  • Settlement is targeted at under 48 hours, and the venue says so rather than leaving it open
  • Political questions listed here that designated exchanges do not offer

Watch out

  • No regulator at all — its own terms say it is not regulated by the CFTC “or any other regulatory authority”
  • The operator writes the rules and judges the outcomes, and its decision is stated to be “final”
  • Accepting the terms waives your right to seek other remedies, with disputes sent to AAA arbitration
  • The terms permit cancelling an account “for any reason”, expressly including because you began a dispute
  • A per-participant cap tied to the federal contribution limit, so position size is constrained by rule
  • The CFTC no-action letters say nothing about determination or recourse, despite being cited as if they did

7. Hedgehog Markets

Permissionless prediction markets on Solana and Eclipse, with very thin books

1.7Prelim

Strengths

  • Trading mechanics are visible in the application itself
  • The venue states its own scope: permissionless prediction markets on Solana and Eclipse
  • Featured markets display their own liquidity figures, so the depth is visible before you connect
  • Runs on Solana and Eclipse, so settlement and balances are on a public chain rather than an operator’s ledger
  • No terms means no clause asking you to waive recourse — thin comfort, but several venues here do ask

Watch out

  • Nothing is published about how markets resolve: eleven likely paths 404 and six documentation subdomains do not resolve
  • Market content sits behind Connect Wallet, so per-market rules cannot be read before connecting
  • No terms, no privacy policy and no named operator
  • Featured markets showed $38 and $503 of liquidity — at that depth a position of any size is the market
  • Third-party descriptions of an oracle are uncorroborated by anything the venue publishes, so they are not used here

8. Opinion

On-chain binary markets on BNB Chain; closed to the US, the UK and all of the EU

5.7Prelim

Strengths

  • The widest category set of any venue added to this site in September, including hourly crypto markets
  • Books were genuinely two-sided across four categories at once when we read them
  • Third in the category by reported volume, behind only Kalshi and Polymarket
  • Publishes concrete dispute terms — a window, a stake formula and the consequence of losing
  • Names its operator in its terms of use

Watch out

  • Closed to the United States, the United Kingdom and all of the European Union
  • The primary resolver is “Opinion AI”, with no account of its inputs, model or sources
  • The review step is written with no actor: who performs it is never identified
  • Whether the team can resolve or override a market itself is not addressed anywhere
  • Only one dispute is permitted per resolution, so the first challenger spends the market’s single appeal
  • No stated jurisdiction of incorporation, licence or regulator

9. Predict.fun

Non-custodial event contracts on BNB Chain, with yield on USDT collateral

5.4Prelim

Strengths

  • Non-custodial: the venue never holds your balance
  • Zero maker fee, so posting liquidity costs only the spread you offer
  • Yield paid on USDT collateral while it sits against an open position — unique among the venues we cover
  • Six of the seven categories we track, the widest verified breadth of any venue we built from primary sources
  • Names its operating entity, which most on-chain venues do not

Watch out

  • Its own documentation describes two incompatible resolution mechanisms, both live on the same day
  • The developer page for the deployed oracle states “No bonding or dispute mechanism (simplified trust model)”
  • Admins can flag questions for emergency resolution, documented in developer pages rather than in the user terms
  • A role holder can settle Chainlink market rounds manually
  • No licence, no regulator, and no stated jurisdiction of incorporation

10. Trueo

Prediction markets on Base where open positions earn yield; closed to the US and Canada

5.2Prelim

Strengths

  • A permissionless optimistic oracle: anyone may propose an outcome by posting a bond, opening a 12-hour challenge window
  • Four named escalation stages ending with 11 randomly selected attesters
  • Constrains its own privileged body — all Oracle Council decisions may be permissionlessly challenged
  • No admin override, emergency power or discretion clause attaches to market outcomes anywhere in the documentation
  • Names its operator and publishes a full restricted-territories list with “We do not make exceptions”

Watch out

  • None of the design is evidenced in operation: there is no public dispute record
  • The final escalation is gated at 250,000 liquid TRUE, putting the last word with large holders
  • Market creation is still restricted to Oracle Council members in the genesis phase
  • The sources a dispute is judged against are not fixed — alternatives may be used
  • No licence or regulator; Samoa incorporation carries no consumer protection a reader could invoke

11. Space

Prediction markets on Solana; no terms or documentation published

2.6Prelim

Strengths

  • Crypto markets resolve on a 15-minute TWAP with Pyth primary and Switchboard as a named fallback — manipulation-resistant by design
  • Real-world events require a 2-of-3 operator multisig rather than a single key
  • Publishes terms at all, which several venues in this cohort do not
  • Documents a 24-to-48-hour flagging route for incorrect resolutions

Watch out

  • The terms grant no right to flag: resolution criteria are “final and binding” and you waive claims over data sources, delays and voiding
  • Space “may cancel or void a Market at any time” and may extend the resolution period at sole discretion
  • It reserves the right to modify the underlying smart contracts at any time, which sits above the TWAP design
  • The AI validation step is undescribed — no model, inputs or evidence standard
  • The site carried no link to terms, privacy, legal, docs, about or FAQ, and /terms returned HTTP 500
  • No volume or depth data is published

How to choose

Access differs more here than in any other category. US-regulated exchanges list election contracts under specific CFTC conditions; offshore platforms list far more political markets but are closed or close-only in several countries. The availability badge on each entry answers the question for your region first.

Before trading a political market, read its resolution source and deadline. Two markets on the same election can settle differently if one pays on the called result and the other on certification.
