Fake Polymarket generator: build a market you can film

First, the line you don’t cross

A fake prediction market in a skit, a meme or a parody is a prop, like the betting slip a character waves around in a film. The same screen posted as a bet you really placed — to sell picks or a tipster service, to fill a Discord, to run a giveaway that doesn’t exist, or to get anyone to stake money alongside you — is prohibited, and accounts that do it are closed. The events are yours to write, so a real election or a real person can end up on the screen. If one does, make it plainly a joke: a believable market at a believable price on a real vote is misinformation whatever you meant by it, and a screenshot of it outlives the video. The rest is in our acceptable use policy.

What this generator makes

A screenshot generator gives you a picture. This one gives you an app. You fill in the fields in the editor, publish, and Pozer’s Polymarket-style prediction market installs on your phone’s home screen and opens fullscreen. It has three screens, reached from the tab bar: Home, with the event cards; Search, which filters them as you type; and Portfolio, with the account’s value and positions. Every priced button on a card opens a keypad, takes the cost out of the cash balance and writes the position into Portfolio, so the screen can be used on camera rather than held up to it.

It’s an original design drawn to the conventions of the genre. It isn’t Polymarket, has no connection to it and ships with none of its name, logo or artwork — “Polymarket-style” describes the kind of screen, nothing more. If you need a single still rather than an app, the editor’s Export PNG (3x) button saves one, and the guide to a prediction market mockup covers that.

Step 1: Give it a name of your own

The App name field sets the name beside the round mark at the top left of the home screen. It defaults to Oracle and takes up to sixteen characters. The name you type in App name (home screen), at the top of the editor, is the one under the icon on your phone, and the editor offers Oracle, Consensus, Longshot and Verdict as starting points. Neither should be Polymarket, and the icon you upload should be one you made or have the rights to use: another company’s name or logo is against our policy, and it’s also what turns a prop into an imitation. The Handle field, @yourhandle by default, prints at the top right of the Portfolio screen.

Step 2: Write events that could settle

Every event is a question, and real markets are written so that someone could settle them: a named thing, a clear outcome and, usually, a deadline. The defaults are built that way — “Fed cuts rates in September?”, “BTC up or down today?”, “Nasdaq closes green today?” and “Champions League: 2027 winner”. A question with no deadline, or one nobody could ever check, is the quickest way to make a market look invented. Give even a silly question the same bones: “Office fridge cleared out by Friday?” reads like a market, and “Is the office fridge gross?” reads like a poll.

You can hold up to eight events. A new one, from + add row, arrives as “Will it happen?” at 62%, with $1.8M of volume, $240K today, $900K of liquidity and 906 holders — placeholders to replace, not figures to keep.

Choose the card by counting outcomes

Each event has three outcome slots, and the card’s shape follows how many you name. A yes-or-no question takes one and gets the chance card, a half-dial with the percentage inside it. A question with two sides takes two and gets a head-to-head, with a split bar and both names in the buttons. A question with several answers, like a tournament, takes three and becomes a list with Yes and No on every row. An outcome whose name is blank leaves the card entirely, whatever percentage sits in the box beside it, so clearing a name is how you turn a list into a head-to-head.

Pictures and categories

Image (optional) puts a small square picture beside the question on chance and head-to-head cards. Without one, the square shows the first letter of the event’s Category in your accent colour, which looks deliberate rather than broken. List cards leave the square out unless you upload a picture. The Category itself prints in the footer of every card and drives the chips, which is step 4.

Step 3: Make the numbers agree

The editor will let any number sit next to any other, so this is the step that decides whether the screen holds up. Four places need checking.

Two sides should add up to about 100

The No-side spread (pts) field prices every No button: at the default of one point, No is 100 minus Yes plus one. A head-to-head card has no No button, though. Both of its buttons buy Yes on their own outcome, and both show exactly what you typed, so the gap is yours to build. The default BTC card is Up 57, Down 44 — 101 in total, the extra point doing the job the spread does everywhere else. Two sides that add to 80, or to 130, are a tell.

A list is only the top of the field

A list shows three outcomes, and when the real answer could be any of a dozen, they shouldn’t add up to 100. The Champions League default is Barcelona 17, Arsenal 16 and Real Madrid 14: 47 between them, with the rest of the competition holding the other 53. Three favourites that add to 100 say nobody else can win. Only when the question has exactly three possible answers should the rows come to about 100.

Volume has to fit the question

Each card’s footer prints the volume, today’s volume and the liquidity in short form — $64M Vol., $2.1M today and $3M Liq. on the Fed card — with the holder count at the right. A market that only exists for one day should have done most of its trading today, and the two daily defaults haven’t: “BTC up or down today?” shows $21.5M in total against $4.8M today. For a close-up, bring the total down towards the day’s figure. Any of these left at zero, holders included, drops out of the footer instead of printing $0, which is the tidy way to show a small market. And unless the size is the joke — the meme guide has a use for that — keep the numbers in proportion to how many people could plausibly care.

Decide what Invested means

Portfolio works out Value and Return for you; the template page explains how. What it leaves to you is Invested, and that one figure decides what kind of account this is. The three default positions cost $6,060 to buy — 4,200 shares at 41¢, 9,800 at 31¢ and 2,500 at 52¢ — and are worth $10,210 now, $4,150 of profit between them. With the $12,400 of cash, an Invested of $18,460 makes Return exactly +$4,150: a fresh account whose only gains are the open ones. The default of $14,200 makes it +$8,410, which reads as an account that has already cashed some winners. Either is coherent. A Return in red above a column of green positions needs a story to explain it.

Today % is the one figure on that screen that isn’t worked out for you. Keep it in proportion: +8.4% on a $22,610 account is a gain of about $1,750 in a day, and the positions underneath should look able to explain it.

Step 4: Match the chips to the events

The Category chips — Fed, Crypto, Football and Markets by default, up to eight — are a working filter. Tap one and the list narrows to the events whose Category matches it; tap it again and everything comes back. The Search tab filters the same way as you type, on the question or the category. That makes the chips something to plan rather than decorate: a chip with no matching event empties the screen to “No markets in” followed by the chip’s name, which looks like a broken app on camera. Give every chip at least one event; the match ignores capitals.

The row above the search bar — Trending, Combos, Breaking and New — is fixed text, not tabs. It’s there to look right, and tapping it does nothing.

Step 5: Colour, currency and cash

Accent, indigo by default, colours the round mark, the cash pill, the selected chip, the active tab and the letter squares; the Yes and No buttons stay green and red whatever you choose. Background sets the screen behind everything. Currency switches every figure between dollars and euros. The cash pill at the top right shows the Cash balance without cents — $12,400 by default — and it’s the number that drops when someone buys on camera, so set it to what the scene can afford.

Step 6: Publish it

Press Create home-screen app. If you aren’t signed in, the editor asks for an email address and sends a six-digit code, then gives the app its own link with a QR code to scan from your phone. Installing it and filming it take by take is in how to film a prediction market skit. Everything works on the free plan; free apps carry a SIMULATED · POZER.COM mark on screen, and Pro at US$12.99/mo removes it.

What gives a generated market away

1. Yes and No adding up to exactly 100 — the spread set to zero.
2. A head-to-head whose two sides add up to much more, or much less, than 100.
3. Three contenders in an open field adding up to 100.
4. A question with no deadline, or one nobody could settle.
5. A daily market that did most of its volume before today.
6. A chip that empties the screen.
7. A Today % the positions couldn’t have produced.
8. A thumb tapping Trending, or a bookmark, and nothing happening.
