ANTE: Stake on this to subsidize the market.

The ability to look for related markets in the API.

Linkable Comments

Ability to optionally privately enter your expectation of outcome when making a purchase, for the purpose of having a personal calibration curve. Justification: I find that making calibration curves for myself is fun and helps improve my forecasting, and that my calibration curve gets less accurate after a few months if I stop practicing. But the practice takes effort, which could be piggy-backed on the forecasting activity of participating in prediction markets for less effort than doing it seperately.

Ability to include a short message when resolving a market

Reminders. Allow users to set a custom reminder to return to a market.

Spoiler tags to hide markets about in progress fiction

Merge duplicate Answers for multiple Answer Questions https://manifold.markets/Honourary/will-manifold-markets-add-a-merge-f

Ability to tip users M$ for helpful comments.

Ability to short multiple choice answers

Retroactively close a market, undoing bets after the new close time. (Reward predictions before the events happened, not betting really quickly after hearing the news.)

Resolve market to probabilities other than market probabilities. Useful for betting on outcomes of other markets.

Short answers on free response questions

Graph showing the pool size of a market over time

A meta-market. Simple exchange that lets you place a bid/sell order for shares of whatever market.

Set a time to stop allowing creation of new free response answers separately from the market close time

We need numerical range questions. Many topics are way more informative when expressed that way, over a Yes No.

Ability to attach (private) personal notes to other users (e.g. to keep track of who you've observed be a good market resolver)

A "poll" category of market. You can buy as many votes as you want but the payout is unrelated to which answer wins. (Could be zero, could reverse the system so bettors get 4% and the creator gets the balance, or something else.)

Reducing the number of personal questions (eg. "Will I do ...")

Market Indicies, Allowing Multiple Markets to Be Combined Into One and Automatically Weighted with Drag and Drop Type Feature

Show currently placed on market overviews, like https://manifold.markets/markets (it is easy to forget where loans were used)

Allow to exclude communities/tags on feed/market overview. It would be nice to not have ability to skip all this gambling ("yes iff pool divisible by 2" etc)

Allow to exclude communities/tags on feed/market overview. It would be nice to skip all this gambling ("yes iff pool divisible by 2" etc)

Allow users to edit their comments

In "Your Trades", show each market's M$ pool

Reduced fees for long horizon markets to increase trading volume.

Upload photos with comments. Useful for proof of results and other fun things.

I would like there to be a feature that integrates something like an RSS feed. If key words or phrases about specific event occurs, trading is suspended until the market is either resolved or the RSS notification is tagged as a false positive. As what often happens, the gains of many bettors are wiped out by slow resolutions of markets.

Statements

Kelly

The ability to subsidize markets, putting up money to enhance liquidity and encourage participation, without taking a particular side of the bet. (The thing that the ANTE option on this market is trying to do, just in a more formal and less ad-hoc way, which would also work for YES/NO markets.)

Aggregate your own trades in timeline view (avoid long list).

Earn interest on M$ tied up in long time horizon bets.

Trade fractional mana

When creating a free answer market, add a starting set of answers without betting.

Combinatorial Prediction Markets

Ability to delete comments.

Load pages faster (Android mobile).

More explanation for people who don't know anything about prediction markets.

Mechanism for making decisions (built-in bundle of conditional markets?) with better incentives for betters (not beauty contest)

Filter OUT market categories on the homepage.

Private messages to users

Ability to select multiple categories of markets on the home page.

Trusted users can add category tags to markets that aren't their own

Add tooltips that explain how everything works

Let a user filter to markets in which they have positions

If the user enters a date, it should be treated as a range from the beginning of that day to the end, not just the single millisecond at which that day begins.

Make the choice of which markets to store locally smarter, so it won't accidentally cross the 5MB localStorage limit.

Add proper inputs for dates and drop downs for categories

Multi-buy in multiple-choice markets

Add a quickbet button where the user inputs their expected probability, and it calculates and places the appropriate Kelly bet size based on their portfolio.

Add a tiny graph/sparkline on each row to show how the market has changed recently

Generate RSS feeds for user-specified queries (like https://hnrss.org/newest?points=100)

Add support for arbitraging similar markets/answers, either treating them as summing to 1 or specifying a target relative change percentage.

Make a userscript that overrides Manifold's default search with Isaac's search

Add an option to display each answer on a multiple-choice market as its own row in the search results.

A column to display the market price X amount of time ago, input by the user

Allow users to define more than one dashboard, and share them via URL with other people

Option to show dates in a standardized day/hour/minute format that all lines up

Add a filter to only show markets the user hasn't seen before.

Make the search boxes look nicer so they're not just a giant pile of input boxes. Lay them out in columns or hide ones the user isn't using or something.

Add an OR conjunction for search terms, so people can search for something like "question includes 'altman' OR 'OpenAI'"

Open markets in new tab by default

Add a "concise mode", which removes all extraneous text from the table, like the percent sign, M$ sign, etc. and aligns them all nicely

Add fuzzy searching that can catch typos and synonyms

Let people resize columns, or add intelligent column resizing

Let people see the limit orders of a selected user in each market

Dark Mode

Add support for other platforms. Polymarket, Kalshi, etc.

Add tiny arrows in each column header as a visual indicator that they can click there to sort the column

Let people see the position of a selected user in each market

Add reminders to check back on a market after some time

Add direct links to user profile and/or group pages, maybe accessible by shift-clicking on them.

Check to see if any of the code has changed upon page load, and if so wipe the cached market data and reload it.

Let people see the profit of a selected user in each market

Fix the graphical issues that cause fields to unfocus and dropdown menus to disappear each time new data is loaded

Add some way for clicking on a group or creator to wipe the rest of the search. Maybe shift-click? Or maybe it should be the default?

Add more complex diff detection so that the client can catch up on what it missed if it loses internet for a few minutes, or at least tell the user it's out of date

Add hotkeys to make trading and searching even faster

Add more sensible step values to the numeric input fields

Allow people to place long-term limit orders

Make the "last updated time" field include edits to the market description

Somehow convince Manifold to waive the API fee if bets are placed via Predictionary

Make it look not-terrible (this suggestion is for aesthetics only, not functionally-useful layout/display features)

Allow users to see whether a multiple-choice market is select-one or select-multiple

Display who can add answers on a multiple-choice market

Give it a better name than Predictionary. (Suggestions welcome.)

Add support for Polymarket front-running. (https://medium.com/@eightyhi/blockchain-based-amms-arent-fit-for-prediction-markets-bbe6ad7a33ca)

Make a row flash when its probability changes

Add a bulk bet button that can bet on all markets in the dashboard

Fix the bug that causes some resolved markets to not be marked as closed

Add a way to view/query detailed historical market data

Add a one-click feedback form on the page itself

Add a filter/sort by recently subsidized

Add an option to change the height of each row such that it's proportional to the width of the interval between the previous market's close time and the next market's close time, so distance down the page represents time in the future.

Fix the bug that causes numeric markets to be displayed as though they were regular percentage markets.
