PREDICTION MARKET TOOLS
How We Check and Select Prediction Market Tools
Our evidence standards, recommendation criteria, pricing checks, AI disclosure and correction process.
What “checked” means
On September 29, 2026 we checked the linked public product pages and official documentation for our curated shortlist. Profiles show supported venues, useful workflows, access or pricing information, limitations and sources. A documentation check does not establish uptime, execution quality, security or profitability. We do not label it a hands-on review.
How recommendations work
We select tools with a clear job, identifiable official site and documented platform support. The hubs group options by workflow. The finder uses explicit platform, task, budget and interface filters and returns up to three matches in shortlist order. We do not invent star ratings, rankings, founding dates, user counts or free plans. The wider directory includes older and submitted records; listings without a check are marked accordingly.
Pricing, eligibility and trading assumptions
Prices are dated snapshots, not quotes. Missing pricing is shown as unverified. A free tier can have restrictions. Analytics support for a venue says nothing about a visitor’s eligibility to trade there. Calculators disclose their fee sources, rounding and assumptions and allow manual costs; verify the actual order quote and current venue rules.
Automation and editorial responsibility
Parts of the news publishing workflow use AI to draft sourced summaries and check for repeated coverage. An automated novelty check is not human fact checking. Tool descriptions and guide updates may also use AI assistance. A byline identifies editorial responsibility and does not imply that an author tested every product or trade.
Commercial disclosures
A directory listing is not an endorsement. Paid placements should be labeled “Sponsored” where they appear, and affiliate links should carry a nearby disclosure. The curated shortlist and finder have no paid-ranking input. If you see an unclear relationship or outdated claim, report it so the listing can be checked.
Corrections and updates
Send the affected URL, the claim and a primary source through our contact page. Meaningful guide updates receive a new modification date; cosmetic template changes do not imply a new product review. See the corrections page.
