Why Belief Index?

Prediction markets are emerging as one of the most efficient mechanisms for aggregating beliefs about future events. But accessing them as an investable asset class remains fragmented, operationally complex, and dominated by single-event risk. Belief Index addresses this gap — applying the same principles that transformed equity investing through index funds to the prediction market ecosystem.

​

Prediction Markets as an Asset Class

Prediction markets allow participants to trade contracts that pay $1 if a specified event occurs and $0 if it does not. The market price of these contracts reflects the crowd’s implied probability of the event. This creates a genuinely novel asset class with distinctive characteristics: The low correlation to traditional asset classes makes prediction markets genuinely interesting from a portfolio construction perspective. An allocation to event-driven outcomes provides exposure to risk factors — political shifts, regulatory decisions, macroeconomic surprises — that are largely orthogonal to equity beta or credit spreads. However, the discontinuous, binary nature of individual contracts makes single-market exposure volatile and unpredictable. This is exactly the problem that indexing solves.

​

The Case for Bundled Exposure

​

Diversification and Jump Risk Smoothing

Individual prediction markets are binary: they resolve to exactly $1 or $0. A single surprising outcome can eliminate an entire position overnight. This “jump risk” makes concentrated prediction market exposure unsuitable for most investors. Bundling multiple markets into an index smooths this risk through diversification — the same principle that underpins equity index investing.

Jump risk example: single market vs. index

Single market exposure: You hold a contract on whether the Fed cuts rates in March, priced at $0.85. The Fed surprises with no cut. Your position goes from $0.85 to $0.00 overnight — a total loss of 100%.Belief Index (7 equally weighted markets): The same Fed surprise moves one component from $0.85 to $0.00, but the other six markets in the basket are unaffected (or may even appreciate on the news). The index moves from $0.65 to approximately $0.53 — a drawdown of about 18%, painful but survivable.If only one of the seven markets resolves unfavorably and the rest remain unchanged, the maximum loss from that single event is limited to approximately 14.3% (1/7 of the basket) — not 100%.

This is the same principle behind equity index funds: no single constituent can destroy the portfolio. The more uncorrelated markets in the basket, the smoother the aggregate return profile.

​

Thematic, Systematic Exposure

Each Belief Index series tracks a coherent theme — interest rate expectations, election outcomes, macroeconomic data releases, or crypto regulatory events. This allows investors to express views at the category level rather than the event level. This thematic approach is standard in institutional investing. Just as a portfolio manager might use a rates ETF to express a view on the yield curve rather than picking individual Treasury maturities, an investor can use a Belief Index series to express a view on a category of event risk.

​

Operational Simplicity

Managing a portfolio of individual prediction markets requires:

• Monitoring dozens of order books with varying liquidity profiles
• Tracking resolution dates and settlement rules for each individual market
• Manually rebalancing as markets resolve and capital needs reallocation
• Handling the operational complexity of multiple positions across different expiry dates and resolution oracles
• Sizing positions appropriately given highly variable market depth

Belief Index reduces this to a single position per theme, with systematic NAV computation, automated resolution handling, and managed custody. The investor’s operational burden is reduced from portfolio manager to shareholder.

​

Resolution-Aware Capital Management

When prediction markets resolve, the capital tied up in those positions needs to be managed. In a self-directed portfolio, this means manually reallocating proceeds from settled markets into new opportunities — an ongoing operational task. Within a Belief Index series, resolution is handled systematically: settled markets contribute their terminal value ($1 or $0) to the NAV, and the series continues operating with its remaining active markets until all positions have resolved.

Who Is Belief Index For?

​

What Belief Index Does Not Do

Honesty about limitations is as important as articulating benefits:

• It does not eliminate binary risk. Even diversified baskets of prediction markets contain positions that will settle at exactly $0 or $1. Diversification smooths but does not eliminate this fundamental characteristic.
• It does not provide instant liquidity. Shares are minted and redeemed at periodic NAV windows, not continuously. This is a medium-term investment, not a day-trading instrument.
• It does not guarantee positive returns. If the market consensus is wrong about the tracked events, or if multiple positions resolve unfavorably, the series NAV can decline significantly — including to zero in extreme scenarios.
• It does not remove counterparty risk. The product depends on the continued operation of the underlying prediction market platform and its resolution oracles.
• It is not a regulated fund. Belief Index is in private alpha. It does not carry the regulatory protections of a registered investment fund.
