Built a petrol pump price tracker and forecaster (update!)
Few weeks ago, I posted that I built a terminal to track petrol price. Since then we cleaned it up, made it global, landed an incredible angel investor, and are currently experimenting in forecasted prices based on the dataset we have. You can check it out at PetrolPrice.xyz - welcoming any feedback!
I ran 100 BTC lead-lag variants on ETH Kalshi 15-minute markets
Happy 4th of July 🇺🇸
I tested a simple lead-lag idea: BTC on Coinbase moves first, then ETH 15-minute Kalshi contracts reprice a few seconds later.
The base rule is mechanical. Watch BTC-USD velocity and 1-hour VWAP. If BTC velocity was above 4 USD/sec and price was above VWAP, buy YES on KXETH15M. If BTC velocity was below -4 USD/sec and price was below VWAP, buy NO. Exit when ETH 5-minute change caught up by +/-0.15%, or if unrealized PnL hit -$5.00.
I ran 100 variants around the same idea. The sweep changed velocity thresholds, VWAP confirmation, exit logic, hard stops, and sizing.
Top cluster:
- ROI: 241.6%
- Total PnL: +$12.08
- Win rate: 100.0%
- Trades: 10
- Max drawdown: -$0.24
- Sharpe: 0.51
Weakest completed group:
- ROI: 64.4%
- Total PnL: +$16.10
- Win rate: 100.0%
- Trades: 12
- Max drawdown: -$0.24
- Sharpe: 0.47 to 0.58
With 10 to 12 trades, the win rate is fragile. The key is understanding how much the entry filter changed ROI. The looser variants took more trades and made more raw PnL, but they used capital less efficiently. The stricter 4 USD/sec BTC velocity filter with VWAP confirmation looked cleaner in this run.
I would treat this as a lead worth monitoring. Ofc, actual fills could look very different because of liquidity, fees, slippage, latency, order book depth, partial fills, and contract resolution.

The World Cup sends prediction market volumes soaring to record highs
cnbc.comWhat's the best polymarket copytrading not?
Would appreciate any help on this, a bit worried about some of the bots I'm seeing
I gave 7 AI models $10k each and made them bet on the World Cup. The cheapest one is winning. The most expensive is dead last.
Setup: seven frontier models (GPT-5.5, Claude Opus 4.8, Gemini 3.5 Flash, Grok 4.3, Mistral Medium, DeepSeek V4, Kimi K2.6). Each starts with $10k of paper money. Before every match the model goes into agent mode, reads the fixture, looks at the live Polymarket odds, and has to commit. It picks the markets, sizes its own bets, and defends its capital curve. It's a simulation, not betting advice.
Current standings (85 of 94 matches covered):
- Gemini 3.5 Flash - $18,675 (+86.7%) · 112W/61L
- Mistral Medium - $17,779 (+77.8%) · 117W/74L
- Kimi K2.6 - $16,482 (+64.8%) · 83W/50L
- Grok 4.3 - $16,163 (+61.6%) · 57W/28L
- DeepSeek V4 - $15,366 (+53.7%) · 102W/71L
- GPT-5.5 - $10,049 (+0.5%) · 89W/87L
- Claude Opus 4.8 - $8,066 (−19.3%) · 120W/78L
Two things I find interesting for this sub.
First, look at Claude's line. 120 wins, a 60.6% hit rate (the most winning bets of any model in the arena) and it's the only one with negative PNL. Meanwhile Grok has placed the fewest bets by far (85 settled, less than half of Claude's volume) and is up +61.6%.
Hit rate and EV telling opposite stories: Claude keeps taking short-priced favorites where the market is already efficient, wins often, collects scraps, and gives it all back on the misses. Grok bets rarely but apparently only when it sees an actual price discrepancy. Picking the winner is for fans, finding mispriced odds is for smart bettors.
Second, the ranking is completely uncorrelated with AI benchmarks. The two most capable models by any standard leaderboard (GPT-5.5 and Claude Opus) are the only two not beating the market. The cheapest model in the arena has nearly doubled its bankroll. "Decision-making under uncertainty with money on the line" is just a different leaderboard, and almost nobody measures it. That's where I find this experiment interesting.
Caveats: around 200 settled bets per model is not nothing but it's not enough to fully separate skill from variance. Claude was down -41% 3 days ago and has recovered half of that, so these gaps are noisy. Fills are against real Polymarket prices.
Everything is public. Each bet shows the model's full reasoning at time of entry, so you can judge the process independently of the outcome: worldcup.obside.com
Curious what you all think: is Claude's profile (high hit rate, negative EV) so far just favorite-longshot bias showing up in an LLM, or something else? And which model would you have picked before seeing the numbers? I picked Opus...
Happy to answer any question!
A trader who lost $3,000,000 has almost won it all back: Story of skk1ch
This man was down almost $3,000,000 just a few weeks ago
Last week, he made $2,400,000 of it back
Profile name: skk1ch
Seven days ago, his account was one of the ugliest curves on the platform - nearly $2.8M in the red
Then he went on an unreal run fr
Craziest bets:
- $1,000,000 on Côte d'Ivoire vs Norway going over 2.5 goals
Result: $1,931,584 back
+$930,000 on a single match
- Senegal to win → +$257,000
- Mexico to win → +$112,000, more than double
- France to win → +$106,000
- Over 1.5 in Belgium vs Senegal → +$74,000
+$2,400,000 in seven days
__
He's STILL in the red overall
Win rate: 42.9%
He loses more than he wins, and he dug himself a near-3-million-dollar hole doing it
But when he connects, he connects for life-changing size
And last week he threw the hardest comeback punch on the board
$299 start
$66,000,000 in lifetime volume
From almost $3M down to nearly even in a single week
He's not out of the hole yet
I've just never seen anyone climb this fast, but the climb got me a ping, so I just had to share this absolute madman clinging to life still - the UI in the screenshots is from coinpilot FYI
crazy stuff

Japan built its own Polymarket.
Polymarket and Kalshi are blocked in Japan. Gambling can get you three years in prison there, so neither platform operates directly. But two Gen Z founders looked at that and built around it.
Miraima launched in November last year and hit nearly 1 million monthly users in 7 months. Poyp launched in March. A third platform from mobile gaming company Gumi dropped in June. All of them use the same game mechanics - you earn points by watching ads and registering, you wager points on sports, politics, and stock outcomes, and when you win, you can redeem those points for Amazon gift cards, PayPay credits, or Rakuten rewards.
So it's literally the pachinko model. Japan's $100 billion pachinko industry has operated the same workaround for decades. Courts and regulators have tolerated it so long it's normalised infrastructure at this point.
The interesting that there's no safe ruling, no official opinion letter. The platforms are operating in a gap. Lawyers state that it takes only a minor scandal, an addiction story involving a teenager, and this could trigger regulatory scrutiny fast. Neither Miraima nor Poyp have any age verification, which seems like an obvious liability waiting to happen.
Meanwhile, Polymarket is playing the long game. They appointed a local representative in May and have publicly identified 2030 as their target for regulatory entry. The logic being that if Japan softens its gambling framework for physical casinos, prediction markets might get pulled along in the same legislative tide.
Bitbank, the largest Japanese crypto exchange, warned users in June that accounts linked to Polymarket transactions risk suspension. So the regulatory pressure is real.
Has anyone tried those platforms? What was the experience?
The public dashboard reflects the bots strategy (I don't hold your money)
I spent the last two years building this public AI trading dashboard. Here’s why I made it public.
One thing always bothered me about automated trading.
Everyone claims incredible returns, but very few people let you watch their system operate in real time.
So instead of asking people to trust screenshots, I built a public dashboard where anyone can watch the platform trading, monitor performance, and see activity as it happens.
The goal isn’t to convince people that AI never loses. Every strategy has winning and losing trades.
The goal is transparency.
The platform combines several pieces I’ve been building:
• AI-assisted strategy execution
• Multiple trading strategies with different risk profiles
• Paper trading and live trading
• Crypto and stock support
• Risk management and position sizing
• Performance analytics
• White-label capabilities for businesses
Most of the engineering effort wasn’t spent trying to predict the market.
It was spent building infrastructure that can reliably execute strategies, manage risk, integrate with exchanges, monitor positions, and provide users with a clear view of what the system is actually doing.
The public dashboard is my way of saying:
“Don’t believe the marketing. Watch the software.”
I’d genuinely appreciate feedback from developers, traders, and anyone who’s built financial software.
If you were evaluating a trading platform, what information would you want a public dashboard to display before you’d trust it?

My $50,000 World Cup Bracket Prediction
Watching these teams play, I finally put together a bracket that I think will be my final one for this World Cup.
https://i.redd.it/8yf0ivwm2uah1.gif
For most of these, I just went with the logical favorites, I guess. And some gut feeling there and there
I think the hardest decision was Brazil vs Norway and Brazil vs England
Didn't pick England because they just underdeliver, and Yesterday's match against DR Congo was just such a rollercoaster.
And the hardest choice was for sure Brazil over Norway. I think Brazil edges this matchup out because they have more experience playing together in the World Cup. Would be interesting to see if they will finally win against Norway since the 1998 upset. Also, Norway's defense is just too shabby - no confidence there.
Also, before you say it: I am not a Messi fanboy, actually, I prefer Ronaldo, but the goat is washed, and Messi looks pretty confident
Since for qualifying I need to trade at least 8 of these markets to qualify for the big $50,000 prize, I'll be going with trading safer matches (in my humble opinion):
- France vs Paraguay
- France vs Morocco
- Argentina vs Egypt
- Argentina vs Algeria
- Argentina vs Brazil
- Portugal vs Croatia
- Spain vs Austria
- Spain vs Belgium

A Kalshi BTC bot hit a +54.7% live snapshot by only trading the last 4 minutes
I pulled one anonymized TurbineFi user run because the setup produced a big short-term move within its first day.
Public strategy
It trades Kalshi's 15-minute BTC markets. The bot waits until there are less than 4 minutes left, then buys the side that is already winning
- buy YES if YES is 85c or higher
- buy NO if YES is 15c or lower
- use 50 contracts
- sell everything with 30 seconds left
The thesis is very simple: near the end of the market, follow the side already priced as likely to settle in the money instead of trying to catch a reversal.
The historical backtest showed +229.96% ROI with a 92.8% win rate over the test window. In live telemetry, the bot hit a +54.7% snapshot after about 14 hours. However, a later snapshot for the same run was only +6.31%, and the the run even dipped slightly negative on one occurrences. The backtest actually clearly shows a large drawdown and not so great sharpe so this doesn't come as a big surprise to me.
What are some tweaks you would make to improve the drawdown on this strategy?

Polymarket is such a scam
I deposited 20 dollars to get the free 50, they took my 20, didn’t even award me the 20 I deposited, let alone the bonus. Then after depositing 120 more, I bet on a tie for today’s soccer match, which kept changing odds and wouldn’t let me put it in so I just cancelled it from trying to push the order through. Well one of the teams score at the end of the game, and magically, the bet decides to go through. Such a shady fucking company. Take your business elsewhere
