Pricing
Every page on Yield3 is free to read, and this website offers no account at all. A Pro subscription adds four modules to the PolySmarter browser extension, and it is bought and managed on the subscription site rather than here.
What costs nothing
Everything this site publishes as a page, with no account and no sign-in:
- The settlement rules in full, with the deadline and the source that decides the payout.
- The order book as it stands when you open the page: the best bid and offer, the spread between them, and the depth resting behind each side.
- What a size you choose would cost to fill — the average and the worst price you would touch, how much of the visible depth it uses, the fee where the venue publishes one, and the price at which the position breaks even. Why the headline probability is not your fill.
- Recent aggressive buying and selling, and how tradable the market has been.
- The other outcomes of the same event, and why their prices rarely add up to one hundred per cent.
What Pro adds
Four modules, all of them about who is trading and what has been published:
- Participants — the addresses that traded this market, for the markets whose trade tape has been reconstructed.
- Concentration — how much of the traded notional sits with a few of those addresses.
- Trade tape — the individual prints, rather than the aggregate of them.
- Information timeline — public posts we collect, placed against the price, each one carrying the time we first saw it rather than a claim about when it appeared.
Three things worth knowing before you pay for any of that. First, all four are built from data we hold for part of the market universe rather than all of it, and a module with nothing to show says which kind of nothing it has instead of filling in — what those states mean. Second, a fifth module, counterparty scoring, is marked Pro in our code but returns “not covered” on every deployment we run today, so it is not part of what a subscription buys. Third, and most important on this page:
Pro cannot be used on this website. There is no sign-in here yet, so the Pro modules appear locked to everybody, subscribers included. Pro is used in the PolySmarter browser extension, which signs in on its own site. Bringing accounts to this website is planned, and this page will change when it happens.
What it costs
- Monthly
- US$39 per month
- Annual
- US$390 per year — 17% less than paying monthly
Prices are in US dollars and exclude tax; any tax due in your country is added at checkout. The amount is shown again on the subscription site before anything is charged, and what Stripe charges is what the configured Stripe price says — the figures above are read from the same table that is reconciled against it nightly.
How a subscription is bought
From inside the extension. It opens the subscription site, you sign in there, and Stripe takes the payment; the Pro key is delivered back to the extension. Nothing on this website signs anyone in, takes a payment, or knows whether you have a subscription — it holds no session at all, which is also why every page here can be cached and served to everybody identically.
How to cancel
From your account on the subscription site, https://insight.yield3.app/account, which opens Stripe’s billing portal. Cancelling stops the next renewal; Pro stays active until the end of the period you have already paid for, and the unused part of a period is not pro-rated. If you are a consumer in the UK or EEA you may also have a statutory right to cancel within fourteen days of purchase, subject to the usual limits where digital content has already been supplied with your consent. The subscription section of the terms sets all of this out in full, and nothing there limits rights you have under consumer law that cannot be limited.
Payment is handled entirely by Stripe and we never receive your card details. Anything else — a refund request, or a charge you do not recognise — goes through support.
