a drunk Jane Street quant drew his trading system on a napkin
it started as a joke.
someone's friend at a bar in lower manhattan. he mentioned prediction markets and this guy lit up.
"i do this for a living. for a firm you've heard of"
two rounds later he was drawing on a napkin. boxes. arrows. labels.
"the crowd repeats six mistakes every single day. we just built detectors for each one"
> base rate neglect
> mispriced conditionals
> thin book slippage
> platform divergence
> favourite bias
> time decay
"that's the whole system"
i asked what it costs to run.
"200 quants. proprietary infra. about $2M/year just to keep it on"
i laughed. photographed the napkin. went home.
3am. couldn't sleep. opened Claude. fed it the photo and one GitHub repo - poly_data. 86 million trades. every wallet. every entry.
said: build detectors for all six.
by 4AM my laptop fan was screaming. 400+ markets scanning per hour. 8 agents deployed. terminal live.
i didn't understand half of what was on screen.
but the P&L number kept climbing.
+$312 by breakfast.
+$1,900 by end of day one.
+$7,400 by end of week one.
+$16,474 right now. 383 trades. 81% win rate.
the scanner finds gaps like:
> AAPL earnings - crowd says 77%. data says 91%.
> Gold $2600 - crowd says 44%. model says 60%.
> Senate filibuster - crowd says 68%. base rate says 82%.
enters. waits 6 hours average. exits when the gap closes.
politics at 93%. weather 79%. crypto 72%.
eight agents split the work. one mirrors whales. one catches Binance lag. one fades favourites. one bleeds theta on dying contracts.
his firm runs this with 200 people. mine runs on $25/month.

long pause.
"you're not supposed to be able to do this"

FUNDED TRADER MODEL EXPOSED
I’ve been blown away by how the funded trader programs ecosystem has grown so enormous yet stayed so under the radar.
Zero mainstream mentions despite a multi-billion dollar ecosystem!
That all ended today with this Bloomberg piece on the predatory practices of funded trader programs. I suspect this is going to be the first of many news stories and eventual regulatory action.
Especially after @matt_levine picked up on it as well.
