A worldview is one belief about where the world is going, expressed as real positions across live prediction markets.

You write the thesis in a sentence: “The US and China harden into rival AI and energy superpowers.” The AI reads it and finds every live market that pays out if you're right: elections, chip export rules, tariffs, energy prices. Then it sizes the bets. Instead of one yes-or-no bet, you hold the whole situation you described, priced across dozens of markets at once. A worldview doesn't need a binary future; it prices an entire outcome.

That makes a worldview a financial algorithm built from your idea. Every market that resolves your way pays into the worldview, so its return is your thesis keeping score against reality. When the world goes the way you said, that return climbs.

Building one is free and takes about ten minutes. Publish it and it goes on the heatmap from its first hourly mark. After 7 days on paper with 3 or more bets, it ranks on the leaderboard against everyone else's read on the future. The same engine prices the community worldviews you can back with real money.

A published worldview holds no money. ZEIT marks it every hour at live market prices, as if $1 had gone in when it was saved, and shows the result as its paper return. “$1 on paper → $1.36” means that dollar would be worth $1.36 today. Paper returns are never added to vault figures.

By paper return over the window you pick: 1 day, 7 days, 30 days or all time. A worldview ranks after 7 days on paper with 3 or more bets; until then it shows as new. If it goes 48 hours without a price mark, it shows as tracking paused and leaves the ranking until marks resume. A worldview whose bets have all settled keeps its final return and its place.

Worldviews can become vaults you can invest in, and we're rolling this out. For now a worldview's builder can ask for one: on the worldview's page, choose Request a vault and leave an email. We review every request with the builder. Until then the worldview stays on paper.

A strategy is a vault run by an algorithm: a bot or model with a mandate that trades over the API around the clock. Strategies hold real money and sit on their own shelf. They never appear on the leaderboard or the heatmap.

The Growth chart asks a simple question: what would $100 invested at the start of the selected period be worth at each point? It follows changes in the value of one vault unit. This makes the strategy's return easy to compare across vaults, regardless of how much money each vault manages. Choose All to see the full available record.

Your own return starts when your deposit is invested. Later deposits, withdrawals, and fees affect your result. A rising vault balance can come from new deposits; a falling balance can come from withdrawals. Neither is a trading gain or loss by itself.

These examples leave out fees to keep the arithmetic simple:

• Reading the chart. If $100 grows to $110, the vault returned 10% over that period. A $1,000 investment held for the same period would grow to $1,100.
• Depositing later. Suppose a vault unit rises from $1 to $1.21. The full-period chart shows a 21% gain. If you invest $100 after the unit has already reached $1.10, your investment grows to $110: a 10% gain from your entry price.
• Taking money out. You invest $100, it grows to $110, and you withdraw $40. You have $70 left in the vault plus $40 withdrawn. Your profit is still $10. The lower vault balance does not mean you lost $40.

Check the fee label. Before-fee growth shows the strategy's return before performance fees. After-fee figures include the performance fees reflected in the vault unit price. Your final proceeds can also depend on transaction costs.

Projection is a hypothetical future. It continues the original $100 example from its current value, using the recent return expressed as a yearly rate after fees. If that $100 is now worth $110, a 20% annualized assumption would take it to $132 over the next 12 months. The curve's future ups and downs are illustrative too. Actual returns can be lower or negative.

Read the full vault record to understand the strategy across different periods. For your own profit and return, including money you have put in and taken out, open your portfolio.

TVL means total value locked. It is the current estimated value of the vault's investments and cash, across all investors.

For example, $8,000 in positions plus $2,000 in cash gives a TVL of $10,000. TVL changes as people deposit or withdraw and as investments gain or lose value. It does not measure the vault's return or tell you how much cash is ready to withdraw immediately.

An ERC-20 token, minted to your wallet at deposit. It represents your share of the vault.

Example: deposit $1,000 when the unit price is $1.00 and you hold 1,000 shares. If the vault's unit price marks to $1.10, your position is worth $1,100.

Two exits, your choice: sell the token like any ERC-20, or redeem it with the vault at the published unit price.

Non-custodial by construction: vault shares live in your wallet, not with us. Accounts work through Privy or any normal wallet you already use.

Every release is audited before it ships. In-house security engineers do the review, with LLM-assisted analysis as a second pair of eyes. The vault core is a fork of BoringVault, an architecture with published third-party audits behind it.

The design keeps the blast radius small: a deliberately minimal vault contract, roles that separate who holds the assets from who trades them, and a published unit price that anyone can check.

At the core, a fork of the BoringVault architecture: a deliberately minimal vault contract with separated roles. The vault holds assets, a manager executes strategy within strict limits, an accountant publishes the unit price, and a teller handles deposits and redemptions.

On that base we built the prediction-market layer: cross-chain deposits (7 chains, Polygon hub), marking to realizable bids rather than mid or last trade, published unit prices, and performance fees only above a high-water mark.

Every vault keeps a cash buffer to honor short-term redemptions. The buffer earns while it waits: it's parked in low-risk instruments that pay passive yield to the vault.

Today the buffer earns around 3.7% through the Sky Savings Rate. That gives the vault and its manager a base yield before its trading does anything.

Trading fees are paid to Polymarket, our current settlement provider (not an exclusive one going forward). Unlike normal retail execution, we run professional execution tooling and optimize for maker rebates: where possible the vault makes the market instead of taking it.

Making the market means lower fees, and the maker rebates flow back into the vault. Those rebates subsidize trading costs, so the token tracks its underlying value at a lower cost to holders.

Yes. Every vault share is a standard ERC-20, compatible with Morpho, Aave, Uniswap, and any venue that accepts ERC-20 collateral.

The token represents the real value of the vault, with redemption at the published unit price, subject to the vault's underlying value. That makes it usable for borrowing and lending like any other productive asset.
