Start with a UKGC licence, then compare crypto.
For UK users, the mistake is copying the US CFTC shortlist or the EU crypto list. Kalshi is a US designated contract market, not a UKGC book. Start with Smarkets, then decide whether a geo-checked crypto venue adds anything you actually need.
How UK users should shortlist
Primary source before any GammaPredict shortlist: the UK Gambling Commission public register. Smarkets appears there; Kalshi’s US DCM status does not.
1) Confirm whether you need politics, sports or crypto narratives.
2) Check platform geo-rules and payment methods that actually work from the UK.
3) Compare at least one non-crypto path if you want lower custody complexity.
4) Use Manifold when you want forecasting practice without jumping straight into capital risk.
Smarkets
UKGC-licensed betting exchange for sports and politics event contracts — the UK licence path, not a US CFTC clone.
Polymarket
Global crypto events overlay — confirm UK geo-policy; this is not a UKGC-licensed book.
Manifold
Low-pressure forecasting practice and community markets while you verify real-money options.
Azuro
Crypto sports liquidity reference for users comparing on-chain sports outcomes.
Kalshi
US-regulated reference for methodology contrast — not a default UK product path.

UK politics & elections
For political markets, compare Polymarket discovery with any UK-accessible alternatives and always read resolution criteria. Cross-link: political event platforms and elections hub.
UK sports
Sports users should not skip exchange-style options. Put Smarkets on the shortlist, then decide whether crypto sports venues add anything beyond odds-like UX. See Azuro vs SX Bet.
Checklist for UK readers

FAQ
What is the best prediction market in the UK?
Smarkets is our UKGC-licence starting point for eligible UK users. Polymarket is a crypto overlay to compare after you confirm geo-rules. Kalshi’s CFTC status does not travel as a UK licence.
Can UK users use Kalshi?
Kalshi is built around a US regulated model. Treat it as a methodology reference, not a UK default.
Are crypto prediction markets legal in the UK?
Product classification matters. This page is editorial only — check local rules, gambling/investments framing and platform exclusions.
What about sports?
Compare Smarkets with crypto sports venues like Azuro/SX Bet only after eligibility checks. See sports markets.
