Frequently Asked Questions

Common questions from investors considering or participating in Belief Index.

​
General

Belief Index is a structured investment product that bundles prediction market outcome tokens into themed baskets (called “series”). Each series provides diversified exposure to a group of related events — like an ETF for prediction markets. See Introduction for a full overview.
Belief Index is designed for finance-literate investors who want systematic, diversified exposure to prediction market outcomes. The product is currently in private alpha and access is invite-only.
No. Belief Index shares are not exchange-traded and do not trade on any secondary market. The mechanics are closer to a mutual fund: shares are minted and redeemed at periodic NAV windows using forward pricing. There is no intraday trading of shares.
Belief Index operates in an evolving regulatory environment. Investors are solely responsible for determining whether their participation is permitted under applicable law. See Disclosures for the formal legal framework.
NAV is computed at periodic NAV windows — currently every 30 minutes (subject to change). Each NAV computation uses the latest available prices from the underlying prediction markets.
Yes. The NAV Methodology is fully published. You can fetch public price data from Polymarket’s order book, apply the published formula, and compare your result to the published NAV. See the “Independent Verification” section of the methodology page for step-by-step instructions.
Small discrepancies (typically in the 8th decimal place) can arise from timing differences — your price fetch may occur seconds before or after the system’s fetch, during which prices may have changed slightly.
A stale NAV computation means the system could not fetch a current price for one or more underlying markets and used the last known good price as a fallback. Stale computations are flagged transparently. See NAV Methodology — Staleness.

​
Investing

During the alpha program, minimums may vary. Contact Belief Systems for current minimum investment requirements.
Transfer USDC on the Polygon network to your designated deposit address. See Deposits & Withdrawals for details.
Redemptions are processed at the next NAV window, not instantly. After redemption, withdrawal processing may take additional time. Belief Index is designed for investors with a medium-term horizon, not those needing instant liquidity. See Redeeming Shares.
Yes. If every market in a series resolves against the tracked outcome, the series NAV would go to zero. While diversification reduces this risk, substantial losses — including total loss — are possible. See Risk Factors.
Resolved markets are priced at their settlement value ($1 for the winning outcome, $0 for the losing outcome). The series continues operating with remaining active markets. When all markets resolve, the series reaches its terminal NAV. See Index Series — Lifecycle.

​
Fees

Belief Index supports three fee types: management fee (annual, accrued per NAV window), mint fee (one-time on investment), and redemption fee (one-time on exit). Fee rates are configured per series and subject to change. Current rates are visible in each series’ details. See Fees.
Belief Systems reserves the right to introduce, modify, or remove fees at any time. Any fee changes are reflected in the series configuration and apply from the next NAV window.

​
Custody & Security

Assets are held in a dedicated custody wallet controlled by Belief Systems on the Polygon blockchain. All holdings are on-chain and publicly verifiable. Withdrawals require human approval, a mandatory cooldown period, and automated solvency checks. There is no independent third-party custodian during the alpha program. See Asset Security.
No. There is no FDIC, SIPC, or equivalent insurance on custody assets. Investing in Belief Index carries custody risk. See Risk Factors.
Yes. All assets are held on the Polygon blockchain and are publicly verifiable. See On-Chain Verification.
Every withdrawal goes through a multi-step process: admin review and approval, a mandatory 15-minute cooldown period, pre-flight solvency verification, and on-chain confirmation. The system also automatically flags suspicious patterns (first-time withdrawals, large withdrawals, rapid withdrawals) for additional scrutiny. See Asset Security for full details.

​
Technical

Assets are held on the Polygon blockchain. USDC deposits and withdrawals use the Polygon network. Prediction market outcome tokens are ERC-1155 tokens on Polygon.
Prices are sourced from the Polymarket Central Limit Order Book (CLOB) — a public API. The system reads the best bid and best ask for each tracked outcome token and computes the midprice.
If the price feed is unavailable, the system falls back to the last known good price and marks the computation as stale. Extended outages could prevent NAV computation entirely, which would pause minting and redemption. See Risk Factors — Technology Risk.
