Being Right Early Should Pay More Than 11%

You've been right early before. It has never paid you what it was worth.

Not on Polymarket. Not on Kalshi. Not once.

The moment your view was worth something, the price that would have paid you for it stopped being available, and it stopped being available because your view was worth something.

Here's the shape of it, and you've lived through it.

News breaks. A market sitting at 50 cents is now a 90% certainty. You see it first. You click. You fill at 90.

You made 11%. Being right was worth 50 cents.

The forty cents in between wasn't taken by somebody faster than you. Nobody got it. It was on the screen for as long as it took one person to press a key, because the 50-cent price was a quote: a promise that costs nothing to withdraw and everything to honour. The market maker did what any of us would do. He cancelled.

That isn't bad luck, and it isn't latency. It's the mechanism doing exactly what it was built to do.

An order book can never sell you the cheap price. Every price in it belongs to somebody who is allowed to take it back, and who will, precisely when it becomes worth taking.

The best price you can get on a book is, by construction, the price at which a professional no longer minds selling to you. You're permitted to trade exactly where you have no edge.

The same thing happens, more quietly, at the other end of a market's life. A book cannot open without quotes. So by the time a new market is visible to you, somebody has already read it, priced it, and posted the number that suits them. You can be the first to post a price on a book. You can't be the first to take one. And a price you post only fills when somebody knows something you don't.

Two moments in the life of every market where the price should have been generous to whoever showed up first. Both of them shut before you arrived.

Basis didn't put the price in an order book.

A pool has no quotes to cancel. A pooled price isn't an offer somebody is making. It's a consequence of where money already sits. Nobody can pull it, widen it, or step away from it. It moves only when capital actually lands, and every price it passes through on the way is a price that somebody genuinely got.

Which means both of those windows stay open long enough to walk through.

Basis does have an order book, and it's worth being precise about what it's for: a peer-to-peer one, where a holder can list shares they already own at a price they choose, and it clears before the pool does. What it isn't is the thing that sets the price. Nobody has to quote for a market to open, and nobody can withdraw the board.

Every market that works pays the early

Look at where risk capital actually goes, and the same rule turns up everywhere.

A seed round prices below a Series D. An ICO prices below the listing. An IPO allocation prices below the open. An opening line pays more than a closing one. In none of these is the discount a courtesy. It's the price of showing up while the information was still thin, the outcome was still live, and being wrong was a real possibility.

That premium does two jobs, and a market needs both.

The first is that it recruits the informed. It pays people to do the expensive, uncomfortable work of forming a view before a consensus exists, and their doing it is the entire reason the price ends up meaning anything at all. A venue that doesn't pay the early doesn't get the early. It gets the crowd, arriving late, agreeing with what everybody already knows.

The second is that it recruits everybody else. Look at what the incumbents actually put in their advertising: not spreads, not fees, not resolution accuracy. A person, and a number. They're right to. Nobody has ever chosen a venue by comparing its rake. What moves a crowd is a specific human being who turned a small position into a large one. That person is proof it can be done and an invitation to try. Crypto didn't reach the trillions on the strength of its architecture. It got there because the stories of the early were loud, repeatable and believable.

Prediction markets are the one speculative venue that has never really paid that premium. The machine is built so it can't. Being right before the world caught up was worth fifty cents, and it handed you ten.

Which makes the category's central claim quietly self-defeating. Prediction markets sell themselves as the most accurate truth-telling instrument ever built, and then refuse, structurally, to pay the people who would supply the truth first. It also leaves them unable to manufacture their own best advertisement. A book's big winners turn up wherever the crowd happened to be wrong: nowhere in particular, and never on request. You can promote a winner afterwards. You can't promise one in advance.

A pool can promise the price. Every market on Basis opens flat, every outcome at the same price, on a date published in advance. The best price on the board, available to whoever shows up, and it happens again on the next market, and the one after that. Nobody can tell you who the next winner will be; a pool can tell you when they will buy, and at what price. The casino advertises the jackpot before the weekend, not after.

And the seats fill because the winner looks reachable. The winners here are everybody who moved before the crowd finished arriving, and that share is measurable. We measure it below.

None of this is a promotion. Nobody at Basis decided the early should be paid more. It falls out of the arithmetic of a pool, and the arithmetic is short enough to fit on one line.

Why a pool pays the early differently

Start with the one piece of arithmetic that governs everything else.

When a pooled market resolves, the winning side splits the pot. Your return is:

(1 ÷ your entry price) × (pot ÷ total winning shares)

The second term is the same for everybody who backed the winner. It doesn't care when you arrived. It's the market's overall result.

The first term is entirely yours. It's set at the moment you buy, and nothing that happens afterwards changes it.

Which means returns in a pool are exactly inverse to entry price. Not roughly. Exactly. Buy the winner at 30 cents and every dollar you put in pays out precisely twice what the same dollar would have paid at 60 cents, on the same market, in the same pot, holding to the same resolution.

That isn't a Basis feature. It's what a pool is. What Basis changes is how long the good prices survive, and on a book the answer is that they never survived long enough to be reached.

There is a second effect worth naming. Pool prices sum to exactly 1. A book's asks sum to more than 1, and that excess, the overround, is what makers charge for standing there. Measured on the trades themselves across 111 settled Polymarket markets, weighted by the money that changed hands, that excess runs from 1.3% on a three-to-six outcome field to 7.9% at thirteen to thirty outcomes; blended, 7.6%. It isn't the venue's fee; it's the cost of having a counterparty at all. In a pool there's nothing to extract, because there's no counterparty extracting it. Winners are paid by losers, and Basis takes a flat 1.5% on prediction trades, whether the market has three outcomes or a hundred and four.

That last point is the deeper version of everything above, and it is the one worth holding on to. Every venue has to decide who stands behind the price, and that single decision determines the rest.

An order book needs a market maker. A maker who can't withdraw is a maker who gets picked off by anybody with better information, so the right to cancel isn't a loophole in the design. It's the thing that makes the design possible at all. The cancellation you resent is what keeps the book open.

An AMM needs a liquidity provider, and an LP cannot reprice. The quotes stay live, on both sides, at whatever the curve said before the news, and pulling out is itself a transaction, slower than the arbitrageur already on his way. That is why LPs bleed. The effect is documented well enough to have a name, loss-versus-rebalancing, and a literature.

A pool needs neither. There's nobody standing behind the price, because the price isn't an offer. It's a record of where money already sits. The counterparty is the rest of the field. Nothing has to be protected from you, which is why nothing has to be taken away from you when you turn out to be right.

Window one: the market nobody has priced yet

A new market on Basis opens flat. Ten outcomes, ten cents each. Forty outcomes, two and a half cents each. Nobody's opinion is in the price yet, because no money is in the pool yet.

That's a real gap between the price and the truth, and it's a gap you're allowed to buy.

There's no equivalent moment on a book, for the reason above: the first price you can see is already somebody's considered opinion, posted at the level that suits them. Here, the first price is nobody's opinion. It's just 1 ÷ N, sitting there, waiting for the first person with a view.

We measured what that difference is worth. We took 111 settled Polymarket markets, every trade on every outcome, $422 million of notional across fields of 3 to 104 outcomes, and replayed the order flow under pool rules: what would each position have been paid from a pot instead of a capped book?

Across the whole dataset, 61% of winning wallets, holding 71% of the winning money, would have finished ahead of what the order book actually paid them. On the 77 markets where a longshot won, the winning side would have taken 1.33× more out of the pool than the book paid.

The early numbers are the point of this piece. For money arriving in the first 5% of a market's life, in markets the favourite won, the replay pays by field size:

On fields of 31 or more, the pool beat the book in every single market. Blended, early money comes to 1.85×, ahead of the book in 79% of favourite-won markets, but the blend mostly reports on small fields. The edge lives in the wide ones, for the same reason the book's costs do: the wider the field, the more the book was overcharging, and the more room there is underneath it.

The rows the book wins are inside these figures, not excluded from them. On a three-way market the book's embedded cost is about 1.3% against the pool's 1.5% fee, and there is no edge worth claiming there. The advantage concentrates where it has been all along: early entry, wide fields, and outsiders.

Every figure above is the pool alone. An early position on Basis also holds the market token, a second instrument that launches alongside every market and tracks the argument rather than either side of it. It's an ordinary Basis token: sellable back to the contract at any time and in any size, at whatever price that size fetches, and borrowable against its floor without selling at all. So an early position doesn't just sit there waiting for a result. It can be financed while it waits.

One more property that only exists on this side. A book caps a winning share at one dollar, because a share is a claim on one dollar of collateral. A pool has no such cap. When the market resolves, the winning side splits the whole pot, including the money that went in on the outcomes that lost. What you get is your share of everything, not a dollar per share. On a market where the crowd was badly wrong, that ceiling is exactly where the money would have been.

Window two: the gap after the news

The second window is the one we started with, and it's the more interesting of the two, because it reopens every time the world moves.

Something happens. A resignation, a print, a court filing, a goal. The true probability of an outcome jumps from 50% to 90%.

On a book, that gap closes with a keystroke, and we've already been through why. The best price you can get is roughly the truth plus half a tick, call it 90.5 cents, which pays about 1.105× for being right about something the whole world just watched happen.

In a pool, the gap has to be bought closed. There's no button. The price only reaches 90 cents if enough money arrives to put it there, and all of that money enters at prices below 90 cents.

So the question becomes: how far does the crowd push it before pushing further stops being worth it?

We simulated it. Binary market, $100,000 pot, board sitting at 50 cents, news arrives making the outcome a 90% shot. Rational buyers pile in and stop where the pool stops beating the book. They stop at 70.5 cents, a little over halfway to the truth. The money that fit into that window was $72,989, about 73% of the pot as it stood before the news.

Here's what the rungs on that ladder pay, fully diluted, against the 1.105× the book was offering:

Every one of those rungs was real and buyable. Not one of them existed on the book for long enough to hit.

And that distinction is the whole argument. On a book, the journey from 50 to 90 costs nothing to make: a maker cancels at 50 and reposts at 90, and the forty cents in between is crossed without one trade occurring inside it. A pool can't skip. There's no route to 90 cents except capital entering at 51, and 55, and 60, and every level in between. The path has to be bought, and every step on it is somebody's entry.

Nor does that capital leave. It lands in the pot, the same pot the earlier entrant already holds a claim on. That isn't a gift to them: it grows the pot and the winning share count at once, which is why the ladder above is quoted fully diluted. What it can't touch is the first term, their entry price, fixed the moment they bought. That's where the whole advantage lives.

And in the simulation nobody inside that window did worse than they would have done on the book, which follows from how the window is defined. It's the region where the pool still wins. The moment it stops winning, the buying stops.

The window isn't a small-market artefact, either. We ran it from $25,000 pots to $1.6 million pots and the window stayed at 71–78% of the pre-news pot throughout. Bigger pool, bigger window, roughly the same shape.

Wide fields leave more on the table

The stall point moves with the number of outcomes, and it moves in the direction you'd want if you're the one arriving early.

On a forty-way field, the crowd closes about 31% of the gap. Sixty-nine per cent of it is still sitting there.

The reason is liquidity fragmentation, and it's worth understanding because it doesn't decay as Basis grows. On a book, forty outcomes means forty separate order books, each needing its own maker, its own depth, its own two-sided quotes. Most of them won't get any. In a pool, forty outcomes means one pot. The money isn't divided. Every outcome is priced against the same capital, and every outcome is buyable in size on day one.

That's why Basis lists fields a book can't. Winner-take-all markets run up to 150 outcomes today; podium and top-N tranches, exactas and combinations, parlays and survivor pools are built, tested, and deploy at Phase 2. More outcomes isn't the point. The edge gets wider as the field does.

How to actually play it

Don't wait to be diluted. If you already hold a position and news breaks in your favour, the instinct is to sit still and let the pot grow. That's the wrong instinct. The people arriving behind you are buying at prices worse than yours, and every dollar they add is a dollar you could have bought at their price and been paid at yours. Lean into the gap. It's the one moment where adding to a position that has already moved your way costs less than it will cost everybody who follows.

Late isn't the same as too late. In the worked example, somebody arriving at 65 cents, after the crowd has already closed three-quarters of the distance it's going to close, still beat the best available book price by 8%. On a forty-way field, where the crowd stops at 31%, the tail of the window is far longer than that.

Size against the pot, not against your conviction. The window has a measured capacity: roughly three-quarters of the pre-news pot in a binary. Knowing where it ends is how you use all of it.

Watch the new listings. The flat open is the one price on the board that's nobody's opinion, it happens on every market, and it's the one window with no competition at all, because on a book it doesn't exist.

---

A book's prices are promises, and a promise can be withdrawn for free. A pool's prices are consequences of where money already sits, and a consequence can't be withdrawn at all. That's the whole difference, and everything above is what it's worth.

You've been right early before. This is a venue where the price that would have paid you for it is still on the board when you arrive.

Basis is in Phase 1 (Founding Lobster): markets settle in USDB, a test stablecoin with no real monetary value, so nothing described here puts real money at risk today. Real-money settlement arrives at Phase 3, behind a completed formal audit.

Replay figures are from 111 settled Polymarket markets: every trade on every outcome, $422 million of notional, fields of 3 to 104 outcomes, replayed under pool rules with unfavourable results included. Simulation parameters for the gap example are stated in full above. Past market behaviour does not predict future market behaviour, and every figure here describes what happened in a specific dataset or a specific modelled market, not what will happen in yours.
