Best Prediction Market Tools for Odds, Tracking, and Analytics

ive most stuck to kalshi and polymarket but im seeing more and more. it seems like the sportsbooks are also starting to adopt some type of prediction market as well. some are more sports centered like prophetx and novig but i feel like theres so many now and its hard to keep up

What tool categories are genuinely helpful and provide a net positive value for trading on prediction markets?

Who else here is addicted to prediction markets? Been farming Polymarket for a while now but the new wave of PM apps getting kinda wild. A bunch of these newer platforms let you spin up your own markets which is honestly way more fun than just trading the front page politics stuff.

Been messing around with ProphetMarket lately — you make a market, pick YES or NO, and the AI literally takes the other side. Feels like arguing with a chatbot. I’m up so far which probably means the AI is washed or I’m a genius temporarily.

A lot of these apps are super under-the-radar right now though. Curious what other degen prediction market toys people are using. Anything weird/experimental/low cap that feels early?

Feed me alpha.

Fragmentation only helps if a new platform unlocks a market the others cannot serve. Otherwise it just splits liquidity and makes price discovery worse. The winning layer is probably not prettier UI, it is unique supply, cleaner resolution, lower fees, and enough depth that a good forecaster can actually get filled.

Every new platform entrant into the Prediction Market space makes the same pitch: peer-to-peer, no house, better odds than sportsbooks. ProphetX, Novig, DraftKings Predictions — same pitch, different logos.

I keep trying to apply the bookmaker analogy and it keeps breaking down.

Bookmaker fragmentation makes sense. Different books have different margins, different risk appetites, different line-setting approaches. Prices persist long enough to be worth shopping around for. Pinnacle is sharper than the average book — and the average book limits you when you win too consistently. So you need multiple accounts, you shop for the best price, and you stay one step ahead of the restrictions.

None of that applies to prediction markets.

Prices between platforms should converge almost instantly. Arb bots close gaps in seconds. There's no equivalent of "this platform prices this differently" because peer-to-peer markets are efficient by construction. And you can't get gubbed — the platform isn't your counterparty, they just clip the commission, so they have no reason to limit winners.

So if prices are the same everywhere and nobody limits you, why does anyone benefit from more platforms?

The only argument I can see is liquidity — but fragmentation actively hurts liquidity. Five platforms with thin markets is worse than one platform with deep markets. More platforms means worse price discovery for everyone.

The one thing that genuinely differentiates platforms long-term isn't regulation or fees. It's what can be built on top of them. A closed, regulated platform can copy the markets. It can't copy the ecosystem of tools that only exist because the underlying data is transparent and permissionless.

What am I not getting? Genuine question...

I’ve been digging through GitHub repos for Polymarket / Kalshi bots, and most of the strategies seem to fall into a few buckets:

market making / limit orders complete-set arbitrage systematic buy-No strategies Polymarket-Kalshi cross-market arb 5-min / 15-min BTC bots weather model strategies LLM-assisted research

The weird part is that a repo can look clever, but the strategy can still fall apart once you add spread, liquidity, sizing, and execution.

So I’m curious: which public strategy types are actually worth tracking seriously?

Not asking for anyone’s secret sauce. More asking which strategy families have enough signal to be measured, journaled, or backtested properly.

I track my positions with just a spreadsheet, nothing fancy. The data aggregation sites help for checking odds across different platforms but most of them lag by few minutes so you gotta be careful with that

Qwidgets (disclosure: founder) is a free workspace-centric approach to managing prediction market trading. The idea is that you compose workspaces from widgets for market data, notes, your portfolio, etc. The goal is to keep all research, monitoring, and execution in a single place so you don't need to switch tabs. You then have different workspaces for different strategies and can access them across devices.

It has realtime data integration with Kalshi, Polymarket, PredictIt, and Manifold. You can optionally add Kalshi accounts to manage your portfolio and trading from within the platform.

You can try it out without registering and it's free to use with no plans for monetization. If you have questions, feel free to post here or reach out directly.

“Ratio” it’s a copy trading based market. You can set your portfolio to copy other people trades. It’s pretty cool. Trade with me on Ratio and get 10% off fees!

If you want to try No-KYC decentralized ones, I can personally recommend Predium Finance - a new project, but with great design and hopefully nice potential

Kalshi and Polymarket are probably the cleanest overall rn. I have also been messing around with all-bettors lately since It is more free to play/social prediction style instead of actual money markets. Different vibe but kinda fun for casual event predictions.

Having multiple platforms helps with censorship resistance.

Conditional prediction markets can be used to hold politicians accountable for their policy proposals. Be suspicious when politicians ban things that hold politicians accountable.

I think the missing piece is distribution.

If every market is a commodity and prices converge, the platform still matters if it owns a different user surface. DraftKings has sports bettors. Meta would have feeds and groups. Robinhood has traders. Kalshi has the regulated US brand. Polymarket has crypto-native transparency and wallet-level data.

So the question may be less "why do we need 10 exchanges with the same markets?" and more "which venue can turn a normal person's existing behavior into a market?"

A platform that gets people to trade from a social feed, creator contest, sports app, or brokerage account may not need better prices at first. It needs the fewest steps between curiosity and a position.

Long term, I agree fragmentation is bad for liquidity. But early on, distribution can look like a moat before liquidity decides who survives.

The Finals are about to tip off, and a bunch of people keep talking up Kalshi over traditional sportsbooks. Kalshi promises exchange-style pricing, no juice baked into the lines, and the ability to arb between platforms.. not to mention, it’s backed by familiar NBA faces like Giannis.

Here is my issue with Kalshi, most prediction market platforms weren't built for sports, and it shows. Kalshi was built for elections, politics, and binary event contracts. Game level liquidity runs dry, markets are restricted, and the spreads on individual games can land worse than what you'd see on DraftKings. Here's how I'd rank the options:

Polymarket | 8.5 /10

Big futures and exact-outcome markets

● Strong liquidity on the championship market and Finals MVP
● Series outcome (4-0 through 4-3) and games-played markets are great for exact-result bets
● Crypto-based, so new users need a wallet or pay 2-3% on an on-ramp
● Sports taker fee sits at 0.75%, low but not zero
● Best for futures sweats and structured bets, weaker for the grind of individual games

Novig | 8/10

A sports-first prediction market

● Peer-to-peer order book, so you're always trading against other users instead of the house
● No vig on matched plays (hence the name), which compounds across a 7-game series
● Full Finals coverage: series, spreads, totals, moneylines, props, futures, parlays, live
● Liquidity on individual games and player props beats most prediction markets
● Lines tend to print sharper than traditional books and the other exchange-style venues

DraftKings | 7.5/10

Trad. sportsbook first, prediction market still ramping

● DraftKings Predictions is CFTC-regulated and live in 38 states
● Combos let you bundle up to 6 event contracts, parlay-style
● Useful as the hedging counterparty against a prediction market series ticket
● Sportsbook side still carries house juice on straight bets

Kalshi | 6/10

The default regulated venue, with real liquidity on the headlines

Looking for markets to trade around weather, what is the best trades you recommend. I have been focused on Chicago / NY markets.

Cross-platform odds/spread trackers are probably the highest-signal-to-noise category. comparing Polymarket vs. Kalshi vs. Limitless on the same event catches real mispricing, not just vibes.

Wallet/smart-money trackers are the next tier: seeing where verified P&L wallets are actually putting size is closer to the genuine edge than most "alpha" accounts on X.

I'd be more careful with copy-trading tools specifically, following someone's fill after the fact isn't the same trade they made, and most of these don't disclose slippage/timing lag. Fine for ideas, not something I'd run as a strategy on its own.

Portfolio/tax tracking tools are underrated for a different reason, not alpha, but actually knowing your real P&L across venues instead of guessing is worth more than people give it credit for.

Put together a running list broken into roughly these categories if it's useful:

Superforecaster here: my team uses napkinbook and averages a 130% plus return in Q2.

How about Robinhood? I like that I don't have to deal with crypto nonsense

I'm having huge success on kalshi because the volume is lower than stock options.  There are severe mispricings that wide spreads don't come close to making up for.

You are probably right for what you've found so far, dig deeper and you can find some edges

Curious to see your stack rank. I weight resolution clarity, fee/slippage when size matters, and whether implied probabilities still look sane after a liquidity shock — the rest is usually marketing.

I put together a list of useful the prediction market links called prediction-almanac on github and made it maintain itself so it doesn't go stale.

I've included all the relevant platforms such as Polymarket and Kalshi with specific information about the geo-restrictions. I've also added datasets which can be useful for backtesting (such as pmxt) and odds feeds which can be used for fair probability estimation, like Pinnacle for sports and Open-Meteo for weather forecasts. Last but not least, I've also added code that people have made pulbic - scanners, dashboards, bots, etc.

If I've left out a venue, dataset, an open-source tool, or anything else you think that the list it missing, tell me and I'll add it.

I've been digging through this research database that pairs Kalshi prediction market prices with an AI model's fundamental analysis on the same questions. Some wild gaps between what traders are actually betting vs what deep research suggests.

The biggest ones:

OpenAI AGI before 2028: Traders pricing it at 26%, the model at 0.7%. That's a 3,700% difference. Make of that what you will.

Meteor strike before 2030: Market has it at 58%, model says 14.7%. So either we're about to get yeeted or traders are collectively watching too much Netflix.

Unemployment above 4.3% in January 2026: Market 69%, model 89%. Model thinks labor market softening is more likely than traders are pricing.

Fed funds rate above 3.25% after March meeting: Market 99% (basically certain), model 94.7%. Interesting that traders are even MORE confident on this one.

There are also markets where they're basically aligned — Bitcoin hitting $150k has them within 1-8% of each other depending on timeframe, and Tim Cook leaving Apple before 2027 is nearly identical (38% vs 37.5%).

The database has 91 total reports across crypto, economics, companies, and science/tech. Each one breaks down market behavior, actual market data, decision-flipping events, and related research.

Curious if anyone here has noticed some of these gaps on Kalshi directly. Are traders systematically overpricing tail risk events, or is the model being too conservative?

TL;DR: Underdog just launched its own licensed prediction market exchange. Best Ball + Fantasy-football-specific markets barely exist anywhere right now despite obvious demand — here are 6 I'd love to see Underdog build.

Kalshi and Polymarket haven't exactly put Fantasy Football at the top of the priority list when it comes to their markets.... Underdog has a MASSIVE opportunity to fill in this gap.

Imagine being able to trade on Best Ball specific markets like Garret Wilson finishing with a better than 16% advance rate or the number of spike weeks Jamo has?

Even content-creator specific markets like how many teams Davis Mattek advances?

There currently isn't even an easy way to take a position on, say, Quinshon Judkins finishing as a Top 12 RB (he will btw). Underdog can do this pretty easily using their own scoring format. We should be able to take a position on any player finishing inside the top 5, 12, 24, on the year!

Here are six markets I would LOVE to see and be able to trade on Underdog.

Market #1 – Advance Rates:

One of the most beloved data points Best Ball drafters chitter about all offseason- Advance Rates. Simply put, it’s the percentage of total teams that rostered Player X and advanced to the second round of Best Ball Tournaments. It’s a simple, widely understood litmus test for whether a player was a good draft pick at cost. Since Best Ball Mania advances 2/12 in every league, our expected advance rate is just that: 2/12, or, 16.67%.

The Market – Will Player X exceed the average advance rate in Best Ball Mania?

Market #2 – Fantasy Finish Markets:

The undisputed flagship market every firm should have readily tradable the second the NFL draft ends. As referenced above, Polymarket has already taken a position here with their… nominally tradable markets on Fantasy Finishes but it’s just not finding any real liquidity. Underdog can own this category. They should offer markets for every fantasy-relevant position (QB through TE) using Underdog scoring, with clear brackets (Top 5, Top 12, Top 24) in addition to the outright “Top Fantasy XX” markets. Volume drafters and casual players alike will show up in droves to take positions on their favorite players and biggest stands (not to mention a good hedging opportunity for those with big fades).

The Market – Will Player X finish inside or outside the Top 5, 12 & 24 at their respective positions?

Wishlist Market #3 – Boom Rates

The game theory behind every draft pick made in a BBM style tournament centers around the player’s weekly ceiling. The more usable boom weeks a player delivers, the more valuable he is.

Define “boom week” cleanly (maybe 20+ fantasy points for RB/WR/TE) and let the market price how often a player hits it.

The Market – Will Player X have 3+ boom weeks (20+ fantasy points)?

Wishlist Market #4 – CLV Market

The ADP landscape on Underdog moves quickly. A 12th-round pick can climb multiple rounds off a single, strong camp report. Sharp drafters shrewdly draft early in the summer to identify those risers and pocket some positive CLV.

Other sites already sell tools that track a drafter's CLV. Underdog should sell the market itself.

The Market – Live Underdog ADP: Will Player X finish higher or lower than his current ADP?

Wishlist Market #5 – Drafter Specific Finishes

I will be the first to admit, there is certainly more ambiguity and nuance regarding this market, but I think it has some legs. Every postseason, popular creators and high-volume drafters regularly flaunt their advance rates and big hits. Or, in the case of Davis Mattek, a popular Best Ball streamer, get roasted for the lack thereof. As annoying as that must be for Davis, it does prove people care about drafter performance, not just player performance. Justin Herzig, another popular BB streamer, already tested a version of this concept last year with a contest letting users draft from a pool of max-entry drafters. Underdog currently has creator-specific contests in the “Badge Bros Brawl” and “Flock Community”. Turning that interest into permanent markets is a natural extension.

There are a few clear ways to spin this, too. Markets could consist of:

Beating the average advance rate

Getting a team through to the finals

X teams finishing top 10,000 in regular season point

Even having a finals-specific market that allows traders who didn’t get a team through to still have some action in Week 17 seems plausible.

The Market – Will drafter X win Best Ball Mania?

Wishlist Market #6 – Highest Scoring Stack (weekly + yearly)

Stacking has become so engrained in the brains of drafters it’s no longer even considered a strategy – it’s practically a rule at this point. It’s been that way for years now. In fact, Mike Leone confirmed that over 87% of all drafters in BBMIII stacked to some degree, and that was three years ago. Markets on the highest-scoring stack (both weekly and full-season) would convert an activity the community already loves into a clean, high-engagement trading product. It’s an easy way to turn the daily contests that the culture enjoys on Underdog into a tradable market.

The Market – Will Stack X finish with the highest combined points this week?

To conclude, there are many ways to keep the spirit of Underdog alive, the loyal consumers satisfied and engaged, while still capitalizing on the Prediction Market paradigm shift.

Anything here you think Underdog would actually build? Any markets I'm missing?
