# Prediction-market directory updates

By PredictionToolkit · Updated 2026-10-27

These notes preserve dated changes to catalog facts. They are not product-release announcements or evidence of live account use.

## Polyfollow fee history

The 2026-09-07 listing described a 0.5% copied-taker fee. On 2026-09-28 the official plans page advertised 0% for copied maker and taker trades with no subscription; this persisted on the 2026-09-29 read. That observation remains in history, superseded in the current profile by the 2026-10-27 correction. No trade or billing event was tested.

## Earlier lifecycle change

-   2026-10-01: Struct’s profile was revised after its announced cutoff and task-specific alternatives were added. Shutdown and replacement compatibility were not runtime tested.

## Profiles added on 2026-10-27

-   Betstack: sequential parlays, with football v0 separated from roadmap plans and untested funded execution.
-   Prediction Index: geopolitical market/model research, constituent transparency and timestamp limitations.
-   Poly Sniper: per-coin self-hosted bot pricing, simulation trial, dependencies and conflicting setup instructions.
-   Rocket: related chart-zone prediction platform with testnet access and unresolved funded terms.
-   Predly: AI research beta, an observed empty event view and the distinction between free access and Pro gating.
-   Polymart: independent discovery directory with free browsing, guides and commercial-surface caveats.

## Facts revised on 2026-10-27

-   0xInsider: Max described up to 25 published daily picks, with API pacing and funding context.
-   99market: inclusion rules, cached prices, conditional APR and separate score weights were explained.
-   Polymarket client: official SDK guidance added cursor resumption, rate-limit handling and realtime-stream cleanup.
-   Adanos Market Sentiment API: operator/API domains, UTC windows, non-directional buzz and commercial-use entitlements were clarified.
-   Adjacent News: official destination, index scales, composite weights and the 15-minute public snapshot delay were updated.
-   Polyfollow: official pricing lists 1% on filled copied taker orders and 0.5% on filled copied maker orders, calculated from order value, with no subscription. Polymarket collects the copying fee at execution; market-specific venue fees can remain separate. No account, order or billing event was tested.

## What these notes establish

Terms can change again. A 0% provider fee does not prove zero venue fees, eligibility, withdrawals, execution quality or profitability. Check the provider and exact market; send a sourced correction through the directory’s reviewed contact process. A source check can update a claim without measuring execution costs.
