Decision guide
What matters most before choosing in this category
The best prediction market depends first on whether you can legally trade there, and then on who resolves a contested outcome. Kalshi is a CFTC-regulated US exchange with narrower listed markets; Polymarket, Limitless, SX Bet and Myriad are open venues with broader coverage and their own dispute mechanics. We rank on resolution integrity and access before liquidity and cost, because a venue can run flawlessly and still take a correct position to zero by resolving against you — and a market you cannot legally reach is not a market at all. Platform volume is shown as context, never scored.

Can you legally trade on this venue from where you live — and have you checked, rather than assumed?
Where are you trading from, and does that jurisdiction leave the venue open to you?
Do you want a regulated venue with narrower markets, or an open one with broader coverage and a dispute process?

Three consumer-platform failures in five months, all during peak-demand events, all re-verified against the cited reporting. Aug 2025: 'a separate outage in August 2025 affected the full platform, including the exchange itself.' Oct 2025: 'roughly half of Kalshi's users were unable to access the app or website during Saturday college football games' while the API kept serving institutional traders and automated market makers - retail was locked out, algos were not. 8-9 Feb 2026 (Super Bowl): the payment rail failed from around 5pm and deposits were still pending in the fourth quarter; funds were debited from… Fully custodial and centrally resolved. Kalshi determines outcomes itself under its own rulebook - there is no external oracle, no public dispute market and no bond; the only user path documented is a settlement request, which 'our markets team will thoroughly review', and its settlement docs concede that some markets need 'manual review'. You are trusting one US corporate exchange's judgement with no adversarial check.

Frequently asked
Questions people ask before choosing prediction markets
What is the safest prediction market?
Safety on a prediction market comes mostly from resolution, not from uptime. A venue can run flawlessly and still take a correct position to zero by resolving a contested outcome against you, so what is scored is who resolves, on what evidence, and what the dispute record actually shows.
Why is platform volume not in the ranking?
Platform volume measures how much attention a venue attracts, not whether it resolves fairly or whether you can legally use it. It is also concentrated: aggregate volume dominated by two political markets says nothing about depth in the market you actually want to trade. It is shown as a fact and never scored.
Who decides the outcome when a market is contested?
It varies, which is why resolution integrity is weighted highest at 32%. Some venues resolve against a named data source, some run a token-weighted dispute game, and some reserve the final call for themselves. Resolution is the only mechanism that can take a correct position and pay you nothing, so the dispute record matters more than the fee.
Why does regulatory access carry so much weight?
Because a market you cannot legally reach is not a market, however deep it is. Access is weighted at 26% for that reason: the ranking answers what this reader can actually trade on, not which venue is largest in the abstract.
