i found a way to find Polymarket insiders.
one of their trades made +400% in a day. there was a 6 hour window to open the position.
this post is the step by step guide:
this wasn't a one-off. maduro, the iran ceasefire, axiom: every time, fresh wallets opened big positions hours before the news and walked away with anywhere from $480k to over $1M.
and every time, those positions were visible in advance.
an insider leaves three traces:
> the wallet is new: less than 2 days old, almost no trades
> the position is huge for this market: more than 2% of its whole daily volume
> the market is quiet: under $50k traded a day
a typical insider wallet: polymarket.com/profile/0xdde…
open its trade history and scroll all the way down: first trade ever, and straight away $30k on a US strike on iran.
how to catch the next one:
1 - open the free bot: github.com/pselamy/polymarke…
2 - send the link to claude code and ask it to set it up on a remote server, not your own computer. the bot has to run 24/7, insiders won't wait for you to wake up. it runs in docker and doesn't need your wallet key
3 - connect telegram, that's where the alerts will land
4 - the bot checks all three traces on every new position on Polymarket by itself
5 - got an alert: open the market and go in on the same side while the price is still near the insider's entry
now you're kind of an insider too.
good luck!

+$500k on sports this week. one wallet buying on Polymarket cheaper than the books.
here's step by step guide:
by game time the book knows everything - lineups, injuries, and where the pro money went.
on Polymarket the market is made by regular people, so the price is sometimes cheaper.
say you buy an outcome at 55c and the book has it at 58c. that little spread is what you can take before the game starts.
how to copy it:
1 - pick a game 1-3 hours before start
2 - find it at a sportsbook and turn the odds into cents with 1/odds.
say one game has 2 outcomes at odds 1.80 and 2.10. in cents that's 55.6 and 47.6, together 103.2. the extra 3.2 is the book's cut.
3 - divide each price by 1.032 and you get the fair 54c and 46c.
4 - put a limit order on Polymarket a bit below the fair price and wait for someone to sell to you.
build a simple calculator in claude code for all the math above. that's your first step toward automating this.
here's his profile: polymarket.com/profile/0x526…
he makes roughly 50% of his profit before the game. the other part he makes live

HOW TO: $12,000 a month on sports arb.
here's the whole path, step by step:
the whole thing in one sentence: you take one side of a match on Polymarket, the other side at a sportsbook, and lock in your profit before it even starts.
then you do it again, every day
1. pick a sport to start with:
> esports
> baseball
> basketball
i counted around 200 arbs a day across these three. each one pays 2%+ ROI and stays up for over a minute
2. open your accounts and fund them:
> Polymarket or any Prediction Market
> one or two crypto sportsbooks
3. sign up for the arb scanner:
spreadmap.io
4. set your filters:
> markets: pre-match
> sports: CS2, Esports, LoL
> venues: your platforms
what to skip:
> Polymarket price in the 50-55¢ range: high chance the match gets canceled
> an arb with 80% ROI: an anomaly that'll most likely get canceled
normal ROI per trade: 1-6%
5. pick an arb:
the scanner has already worked out how much to put on Polymarket and how much at the sportsbook. then open both trades back to back.
wait for the match to end
collect your profit
open the next arb
save this post and go through the steps when you've got a free evening
POV: you watched random guys make $500/day with sports arbitrage
and still had no idea how they kept finding so many profitable opportunities
avg $1,230/day on Polymarket. it comes from changes in the weather forecast, which is free and open to everyone.
the setup guide is in this post
the market already prices the forecast itself pretty accurately.
the money shows up the moment the forecast changes and the price hasn't yet.
how it works in practice:
when a new forecast for the next day comes out and the temperature in it moved by at least 0.5°C, you buy the option one degree closer to the new forecast.
say the morning forecast promised 16.8°C in London, so the 17°C option is the priciest. in the afternoon a new forecast comes out with 15.8°C. your job is to buy 16°C while it's still cheap.
the buy range where the EDGE holds: 5¢ to 60¢. the faster you do it, the higher your ROI
how to set it up:
1 - get forecasts for free on Open-Meteo. it has the american GFS model and the european ECMWF. use the airport coordinates, that's where Polymarket measures the temperature.
2 - the bot should check on a timer whether a new forecast is out, and if it is, compare it to the previous one.
3 - if tomorrow's high moved by 0.5°C or more, the bot buys the option one degree closer to the new forecast.
4 - keep each trade under $25. cheap sellers on these markets are thin, and more size will eat the edge.
one bot trades these forecast shifts across 50 cities every hour.
in september that's avg $1,230/day
here's the profile: polymarket.com/@Bilberry?via…
$700/day on the 5m BTC market.
Polymarket x Binance.
it repeats hundreds of times a day.
the whole thing fits in one line: when to buy, at what price and how fast.
the bot watches BTC on Binance and uses it to work out what the UP share on Polymarket should cost right now. if that price jumps 20c+ within 5 seconds and goes over 60c, while Polymarket is still selling the share 10c+ cheaper, you buy in that same second.
say the window opened at 83,200. in 5 seconds BTC on Binance goes from 83,215 to 83,330, with 2 minutes left in the window. by the math UP goes from 55c to 77c, and Polymarket is still selling it at 56c. that's a 21c gap, you buy.
how to run it yourself:
prices on Polymarket are set by people and bots who watch Binance and adjust to the price there. so Binance is what we care about first.
we're waiting for sharp price jumps.
what we're after is the gap between Binance and Polymarket.
here's the edge:
first - your bot has to tie the $ price on Binance to the share price (¢) on Polymarket.
second - the bot has to compare the exchange price and PM every second.
the moment a 10c spread shows up, the bot opens a trade on Polymarket in that same second, in the direction Binance moved.
here's a wallet that traded it:
polymarket.com/@dgdgt345dfgd…
the market gives 83% odds that the predict.fun token launches before the end of the year. farming it can make you $200/day.
this post is the step-by-step guide
the last project backed by Binance dropped 704M tokens in its airdrop. at the peak that was about $12k per wallet.
predict fun has the same backer and it's already built into Binance Wallet. no token yet, but they're hinting it's coming soon
to farm it you open two trades on the same event, on opposite outcomes.
that's how you farm points on predict fun and make 3-6% per trade off sports arbitrage
here's how:
1 - make an account on predict fun and 1-2 crypto sportsbooks
2 - open the arb scanner - spreadmap.io
3 - set your filters: pre-match, esports (easiest one to start with), venues predict fun plus the books you signed up for and funded. that's how you farm points and get paid.
4 - find a trade with 3-6% ROI
5 - open it.
when the match ends, collect your profit, move your capital around and open the next trade.
make sure you use the trial, it gives you 3 days of free access. in the spreadmap traders chat, in the updates thread, there's a bonus promo for 4 more days of your subscription.
if the token gets delayed you lose nothing: the profit from your trades is yours right away, and the points keep stacking
$POLY isn't out yet, and farming it already pays 3-6% a day. just open two trades on the same match.
the whole path is in this post
HYPE was worth $4.2b on airdrop day, now it's $86b. people who farmed it early got $13k per wallet on average.
Polymarket makes 4x more, and its token hasn't launched yet
you can farm it at a profit: take one side of a match on Polymarket and the other at a sportsbook.
the first trade goes toward your airdrop volume, the second locks in your profit before the match even starts, thanks to arbitrage
here's how:
1 - make an account on Polymarket and 1-2 crypto sportsbooks
2 - open the arb scanner - spreadmap.io
3 - set your filters: pre-match, esports (easiest one to start with), venues Polymarket plus the books you signed up for and funded. that's how you make volume for the drop and get paid.
4 - find a trade with 3-6% ROI
5 - open it.
when the match ends, collect your profit, move your capital around and open the next trade.
make sure you use the trial, it gives you 3 days of free access. in the spreadmap traders chat, in the start here thread, there's a bonus promo for 3 more days of your subscription.
when $POLY launches, you'll show up to the airdrop with your volume already farmed and your profit already looted
GTA VI on Polymarket pays ~40% APR. it looks like a nobrain trade
and here's why:
pre-orders are already open and rockstar set pre-load for november 12.
in 19 years rockstar has never pushed a set GTA date with less than 75 days to go. right now there are 45 left
take-two has $8B of annual revenue riding on november 19.
in August they confirmed the date to investors one more time.
there's only one risk.
in 2010 Rockstar pushed Red Dead Redemption back 3 weeks, 55 days before release.
if GTA VI goes the same way, release slides into december and YES goes to zero.
market's here, November 30 line:

farming the $POLY airdrop costs you nothing.
i know a guy who did $348k vol for $0
this might be the biggest airdrop in crypto history, the company is valued at $21b.
to make volume you have to trade.
but you can skip that part!!
here's how:
1 - open an event with a bunch of outcomes. elections, sports leagues, whatever
2 - split $1 into a YES + NO pair on one candidate. technically it's not trading, you just swapped a dollar for shares
3 - convert the NO and you get YES on every other candidate. simple logic: him losing (NO) = someone else winning (YES)
4 - sell all the YES and you get back almost everything you put in. this is the step where the airdrop volume gets made
5 - one loop costs you about 0.9% in fees. part of it comes back as rebates if you sell with limit orders instead of hitting bids - that's the cheapest way to run it
IMPORTANT! pick liquid events, the bids are already sitting there for you to dump your positions into.
on fresh markets the book is empty, so you risk sitting on locked funds and going negative
here's the guy farming the drop this way: polymarket.com/@kneelbeforet…
but don't look at his PnL.
with almost half a million in "profit" his biggest actual win is $354. the rest comes from an entry price of a couple cents that he never paid
this wallet pulls $320 a day out of weather markets on Polymarket. it started with less than $1,000
the whole thing is two buttons:
the first one puts him in the book on both sides of the same market.
the second one turns the pair he collected back into a dollar, before the market even resolves.
i reverse engineered his loop step by step.
here's how he runs it:
1 - he takes the daily weather markets. every degree is its own outcome. that's about 130 events a day
2 - one event (one city) runs him about 58 trades and $155
3 - he stands on both sides: NO around 76c, YES around 21c. 81% of his fills land on limit orders, the rest he picks up at market
4 - once the set is complete he swaps it for $1. the gap between the buck and what the set cost him is his margin
the set doesn't always come together. what's left hanging he just sits on until it resolves, and that's about the same money again.
43% of his orders go in before the day even starts in that city.
the same dollar goes around the loop all day long.
that's how he's bought $1.27m of contracts while never holding more than $975 of his own money in play
here's his profile: polymarket.com/@0x496f76bd5c…
