Your audience is already arguing about what happens next. Every day, the communities you built are debating outcomes – sports, crypto, politics, culture – and you make nothing from it. On Halley, you open a market on it in sixty seconds, point your crowd at it, and keep 80% of the resolution fee. It is your market, not a post that scrolls away.
This is the open prediction market network. No operator in the middle. No curator deciding what gets listed. No platform taking the upside you created.
The problem with every platform that came before
The platforms that dominate prediction markets today operate like Netflix. An internal team decides what gets listed. They choose the questions, control the economics, and keep the revenue. The people who actually build the audiences, do the research, and bring the crowds walk away with almost nothing.
Halley flips that entirely. Just as Shopify democratised e-commerce and YouTube democratised content creation, Halley hands the infrastructure and the economics directly to the creator. No central team decides what markets exist. You do.
How it works
Open a market in about sixty seconds for about a dollar. No registration. No application. You define the question, set the outcomes (between 2 and 10), write the resolution criteria, and set your resolution fee between 1% and 10%. Your market goes live immediately.
You do not need to put up liquidity. Traders bring their own capital to the order book. You bring the crowd.
But who does your crowd trade against? Each other. A market has two sides because your community already has two: the people sure it goes one way, and the people just as sure it goes the other. On Halley they take opposite ends of the same market – the argument already running in your comments becomes the order book. You are not putting up capital and waiting for strangers to arrive; the crowd you bring is the counterparty to itself. Books are thin where no crowd has shown up yet – which is exactly why bringing yours is the whole point.
When the market settles, 80% of the resolution fee goes directly to you. 20% goes to the protocol. That is the entire split. No platform taking the middle.
What the fee actually means – and why it is charged on the gain, not the stake
The resolution fee on Halley is charged on the settlement gain, not on the face value of the share. This is the detail that matters.
Here is how it works. Every outcome share is worth $1 if it is the correct outcome and $0 if not. The market prices each outcome in real time – the price reflects the crowd’s live estimate of probability. When the market settles, the fee applies only to the difference between what the correct outcome was priced at and its full $1 redemption value.
A concrete example. Five-outcome market: which chain leads DEX volume in Q4 2027? Your resolution fee is 5%. At market close, the prices reflect what traders believed:
- BNB Chain: $0.35 (favourite)
- Ethereum: $0.25
- Solana: $0.20
- Base: $0.15
- Other: $0.05
The upset lands. Base wins, priced at $0.15 at settlement.
The settlement gain is $1.00 minus $0.15, which is $0.85. The fee applies to that gain only: 5% of $0.85 is a 4.25% haircut, not 5%. Each correct share redeems at $0.9575, not the $0.95 a flat fee would leave – on a $100,000 market, $750 more in your crowd’s hands.
Your take as the creator, on that same market:
Total fee: $4,250. Creator receives (80%): $3,400. Protocol receives (20%): $850.
If the favourite had resolved instead – BNB Chain at $0.35 – the settlement gain would have been $0.65, the effective fee 3.25%, and you would have received $2,600. The fee scales with information value: the markets that surprise pay their creators most.
The fee rewards accuracy, not just activity.
What makes this structurally impossible on any centralised platform
On Halley, trading is free. No protocol fee on any trade. The resolution fee is the only fee the protocol charges, paid only by those who were correct, only on their gain, only when the market settles. The creator earns from the information value their market generated – not from a cut of every transaction.
This cannot be replicated by a curated venue. To copy it, a platform would have to hand over the revenue it uses to fund its curation, its marketing, and its operations. None of them will.
How outcomes get resolved
When the event closes, independent Market Managers verify and announce the correct outcome. If they are unable to reach a result, community resolution becomes available – community members can also announce an outcome. That is the extent of the process. The creator does not need to do anything.
The proof is not a promise – it is on-chain
The entire Halley protocol runs on immutable smart contracts on BNB Smart Chain. The contracts are deployed and audited. The fee formula, the 80/20 split, the settlement logic – all of it is in the code. The core mechanics cannot be rewritten after deployment.
Your shares are ERC-1155 tokens in your own wallet from the moment your order fills. No one holds your position for you. No operator can freeze it or move it. No one can close the network.
Trust the chain. Not us.
The mash-up market – what only an open network can host
One thing Halley makes possible that no curated venue can replicate is the mash-up market. A single market can combine outcomes from entirely unrelated domains.
What happens first this Saturday – Real Madrid scores, Bitcoin crosses $100,000, or Taylor Swift posts on Instagram? One market. Multiple domains. One on-chain outcome.
A curated platform cannot host this. Their architecture forces each event through its own approval and listing process. On Halley, outcomes are arbitrary labelled options inside a single market. The protocol does not care where the truth comes from, only that it is publicly verifiable.
Three separate audiences – football fans, crypto traders, pop culture followers – pulled into one market: three thin streams becoming one deep book. One market, one resolution fee, to the creator who opened it.
A note on protocol parameters
The configuration values and defaults behind the process described here reflect current default settings. These parameters are adjustable within defined bounds as the network matures.
Open your market in sixty seconds – about a dollar, no liquidity to put up. Point your crowd at it. Keep 80%.
