i'm running a MEV attack on everyone trading polymarket
$100 → $700,000
and you have no idea
your transaction sits in the polygon mempool for 400 milliseconds
400ms i'm already inside and already making money off you
it's called front-running
it's legal
and there's nothing you can do about it
the setup:
you hit "confirm" on $80,000
12ms later my node sees you in the mempool
340ms before the block i'm already in the position
you move the price with your entry
i'm already there
you buy at a worse price than me
every single time
no exceptions
23 days of MEV on polymarket:
→ best trade: whale dropped $200K on iran strike i front-ran them by 290ms +$18,400
→ max drawdown: 2.8%
→ net: $628,000
all you need is a node on polygon $47/month
while you're watching the price i'm watching the mempool
while you're entering i'm already exiting
you think you're trading the market
you're actually trading against me
only hardcode only RUST
did you even know this existed?

@sterlingcrispin @gemchange_ltd Because thats a lie. That bot runs a cumulative avg cost algorithm it's not a hedge trading bot. His trades are public. Take a look.

@gemchange_ltd This doesn’t really add up your visualization tracks 140 trades and $40k volume but somehow it’s across 40k pairs? How could the pairs be 300 times greater than the number of trades? And the running P&L just fluctuates between $2k and -$2k, I think this vis is way off

Jane Street visualization
This is what $324K in 25 days actually looks like on Polymarket
I started tracking a fresh 15-minute market from the second it opened.
The visualization reveals:
Bot enters one leg after market opens.
Waits for spread dislocation. Enters the opposite side when price shifts.
Total position cost: 84-96 cents. Resolution payout: $1. Both sides held simultaneously.
Daily PnL: $5K-$33K.

Jane Street deleted identity. But not wallet. I tracked 14,822 trades. Yet up $324K. Here's why the name "Jane Street" was never a joke. On 97.7% of markets, he holds Up AND Down positions simultaneously. Delta neutral. explaining: Polymarket 15-min crypto bcs MM haven't arrived. Retail is guessing direction. Spreads blow out to 8-15 cents between Up and Down on different time windows. He enters both legs, not at once, but when combined cost is under $1. Say 48c for Up, 46c for Down = 94c total. Market resolves. One leg pays $1. Not just arbing static spreads but timing entries around volatility compression. When BTC consolidates, both outcomes drift toward 50c. He loads up. When directional move hits, one leg resolves Average hold time: 8-12 minutes. 23 out of 25 days green. $5K-33K daily. The rebrand makes sense. "JaneStreetIndia" was too loud. Same wallet. Just quieter now. account: @Account88888?via=888" target="_blank" rel="nofollow noopener">polymarket.com/@Account88888?…

We printed money on Starlink + PolyMarket.
$24k in 15 days. Two devs, no insider info, no signals, no leverage.
Sounds weird? Yeah, it did to us too at first. But when you break it down, it's almost stupidly simple.
The Setup
@Polymarket markets always resolve to $1.
If UP + DOWN < $1 -> you buy both sides -> guaranteed profit when it resolves.
This isn't secret alpha. Everyone knows this. The problem? Speed.
Those gaps exist for like 2-3 seconds max. Bots everywhere. Humans can't react fast enough.
The Real Edge
Polymarket sits behind Cloudflare. Order matching depends on geography. Milliseconds matter.
So we built:
VPS near their infrastructure
WebSocket feed tracking live prices
Scanner watching for UP + DOWN < $1
Auto-buy when it triggers
Nothing crazy. No AI/ML bullshit.
The weird part: Starlink
@Starlink satellites orbit around 340 miles up.
When one passes nearly overhead, latency doesn't just stay stable - it drops.
Fewer hops. Shorter distance. Physics.
During those windows our orders hit the book milliseconds earlier than competition.
That's it. That's the whole thing.
Scanner finds gap -> orders arrive faster -> both fill -> market resolves -> $1 payout.
Do this hundreds of times.
Results:
~$24k profit, ~15 days (PM gabagool-inv)
Costs: Starlink subscription + VPS + our time
Just math + network physics. No gambling.
If this scales the way it has been, $1M in 3 months isn't unrealistic.
Real question though:
Is this a temporary inefficiency that'll get arbed away or is infrastructure arbitrage massively underpriced right now?

btw all of those were supposed to be revolutionary tech

@thegaboeth Your pfp worths less than 1 eth and you are still not following me

@goldenbronny Always wanted one of those. You can't say NFT without mentioning the apes. Doesn't matter whether the market is dead and people sell for 10% of their costs to lose their money on meme coins. NFTs will come back and i bet it's sooner than later.

If BAYC is really going to 0 like everyone seems to think
I'm going to buy all 10k right before 0
Then invite 9,999 friends with me to the next ApeFest
Because Garga is not going to stop throwing parties
Clubhouse is still getting built
Yuga is going to keep doing cool shit
And I'm addicted to jpegs
Plus, Yuga doesn't make shit on royalties... so they aren't dependent on me trading them
Give me all 10k for 0 and fuck off

Mutants are under 1 eth. Finally.
craigscoinpurse@craigscoinpurse
If Mutants go to .25 I’ll cop one.
