10-15 good trades are more than enough for a spectacular year. And we had a few already $SNDK, $MU , $AXTI , $WDC , $STX, $LWLG , $INTC $NOK and way more. As I always say all our effort should be in placing ourselves in places where these outlier trades can emerge easier and naturally.



This Polymarket trader has 2,668 trades, 99% win rate, and skipped every loud market on the platform It sounds impossible until you see how simple the math behind it is ECMWF and GFS forecasts vs a casual order book - the gap is wide and compounds daily Here's the system: He doesn't predict weather He prices against it. ECMWF and GFS already know the answer - he just acts on it. The niche: Toronto. Taipei. Tokyo. Manila. Karachi. Singapore. Jeddah. Lagos. Paris. Munich. NYC. Chicago. Denver. Daily temperature binaries. Nothing else Three entry patterns: → Buy No at 85¢–99¢ on exact-degree questions "will Madrid hit exactly 16°C" - hitting one specific degree is rare. No wins almost every time Example: Taipei 29°C No at 85.3¢ → +$438 → Buy Yes at 95–98¢ on threshold questions when models are confident "will Karachi hit ≥41°C" - when forecast clears it cleanly Example: Karachi ≥41°C at 98¢ → $7,230 ticket → +$137 → Buy 3¢ lottery tail bets on rare-but-possible outcomes Example: Paris 22°C → $9 invested → $260 payout → +2,766% The math: Ticket sizes: $1K–$7K Profit per trade: 2–15% Hold time: 1–3 days Cities traded daily: 20+ Active position value right now: $108 Same capital recycled across dozens of cities every single day Why it works: ECMWF and GFS produce sharper probabilities than the Polymarket order book at 24–72h horizons. The book is full of casual users He's pricing against actual physics The risk profile: Each trade has convex downside - lose 100% if wrong Diversified across 20+ uncorrelated geographies A freak weather day in one city barely dents the book The lottery tail bets are the asymmetric upside layer The key insight: The loud markets are where attention lives The quiet ones are where the math wins He's not smarter than the market He's just running a public model against a casual order book The atmosphere is the only thing that can beat him And it almost never does






my claude bot BEAT a quant fund every morning it: 1. pulls every active market 2. runs Kelly Criterion on each position 3. flags anything where f* is positive and above 0.08 f* = (bp - q) / b b = payout odds p = claude's probability estimate q = 1 - p if the number is positive - edge exists if it's above 0.08 - it's worth entering been running this for 4 months average weekly return: +$2,100 last tuesday it flagged 6 markets simultaneously all positive Kelly all correlated to the same fed announcement entered separately as usual: +$890 then i calculated what one parlay across all 6 would have returned +$4,800 started stacking correlated kelly flags into one parlay through @Poly_Parlay the same week last 3 weeks: +$4,200 +$3,800 +$6,100 try parlay setup yourself: t.me/poly_parlay_bo… this is the only bot that lets you combine different markets into one position result? you win MORE on same markets cause odds multiply thank me later




Grateful for the years of independence, I'll be closing out this brokerage account. I'm thrilled to be embarking on my journey in the realm of fund management with acceptance of a direct closed ended investment from a global macro strategic fund into my one-person LLC. As the main PM with a minority stake going forward, I'll continue to share my weekly diary if time and jurisdiction permits. For those keen on making their mark in the professional space, show your passion, be thoughtful and honest with your struggle.
