TL;DR - Verified Data
- Trader:
0xdacf9f8d0341fa3770fae5c7ccd9dcfed23e3c74 - Total Profit: $8,897 (verified from blockchain)
- Win Rate: 85% across 200 trades
- Strategy: Only buys outcomes at 0.996-0.999 (99.6-99.9% probability)
- Average Position: $186 (median: $20)
- Pattern: "Near-certain arbitrage" - profits from almost-guaranteed outcomes
The Strategy
Most traders look for mispriced 50-70% markets. This trader does the opposite: they exclusively buy outcomes that are already 99.6-99.9% certain.
At first glance, this seems unprofitable - why buy something at 99.9¢ that only pays $1.00? The answer lies in volume and win rate.

How It Works
Example: Real Verified Trades
Trade #1:
BUY YES @ 0.999 for $500
Market: [Almost certain outcome]
If wins: +$0.50 profit (0.1% ROI)
If loses: -$500 (lose everything)
Trade #2:
BUY YES @ 0.997 for $16.57
Market: [Near-certain event]
If wins: +$0.05 profit (0.3% ROI)
Trade #3:
BUY NO @ 0.999 for $1,157
Market: [Outcome almost impossible]
If wins: +$1.16 profit (0.1% ROI)
The Math
Why 0.1-0.4% Per Trade = $8,897 Total
The strategy relies on compound volume:
Strategy Formula:
Small Edge × High Volume × High Win Rate = Profit
Real Performance:
- 200 trades @ $186 average = $37,200 total deployed
- 85% win rate (170 wins, 30 losses)
- Average edge: ~0.3% per winning trade
Profit Calculation:
170 wins × $186 × 0.003 edge = $94.86 per cycle
But actual profit = $8,897 total
Reality: Variable position sizing + larger edges on some trades
(Trader sizes up to $1,864 on highest-conviction near-certain bets)
Risk-Reward Analysis
| Scenario | Probability | Profit/Loss |
|---|---|---|
| Buy @ 0.999, Win | 99.9% | +0.1% |
| Buy @ 0.999, Lose | 0.1% | -100% |
| Expected Value | - | +0.01% |
Key Point: Even a 0.01% edge becomes profitable at scale. With 200 trades, small edges compound.
When This Strategy Works
1. Resolution Certainty
These markets are priced at 99.9% because the outcome is almost certain:
- Sports games with 30+ point leads in final minute
- Elections after all votes counted except formality
- Crypto prices after event occurred but before oracle resolution
- Binary markets moments before resolution
2. Oracle Timing Arbitrage
Sometimes the outcome has ALREADY occurred but market hasn't resolved:
Example Scenario:
12:00 PM - Election called by major networks
12:05 PM - Polymarket still trading at 98¢ YES
12:10 PM - Buy YES @ 0.98
1:00 PM - Market resolves YES
Profit: 2% in 50 minutes (risk-free if outcome certain)
3. Liquidity Provision Premium
Sometimes markets need liquidity at 99.9%:
- Large trader wants to exit $10K position
- Market maker needs to balance inventory
- You provide liquidity and earn 0.1-0.5% premium
- Near-zero risk because outcome is almost certain
Why The 85% Win Rate?
This trader doesn't achieve 99.9% win rate despite buying 99.9% outcomes. Why?
Possible Explanations:
1. Oracle Failures (Black Swans)
15% loss rate suggests occasional "impossible" outcomes occur:
- Sports game with 99% win probability still loses 1%
- Oracle errors or disputes
- Last-second reversals
- Market manipulation or incorrect resolution
2. Aggressive Entries
Trader might buy at 99.7% thinking it should be 99.9%:
- Pays 99.7¢ for outcomes that are only 98% certain
- 2% of time, loses entire position
- 98% of time, earns 0.3% profit
- Net result: 85% win rate but still profitable
3. Multiple Near-Certain Outcomes
If trader spreads $1,000 across 5 different 99% markets:
- Expected: 4.95 winners out of 5
- Reality: Sometimes only 4 win, 1 loses
- Win rate: 80% (not 100%)
How To Replicate
Capital Requirements
- Minimum: $1,000 (to make 50+ small bets)
- Recommended: $5,000+ (to match $186 average × 25 concurrent positions)
- Risk per trade: 2-5% of capital (since 99% likely to win)
Entry Criteria
1. Find near-certain markets
- Price: 0.995-0.999 (99.5-99.9%)
- Outcome is obvious or already occurred
- Resolution is imminent (< 24 hours)
2. Verify certainty
- Check if outcome already happened
- Confirm oracle source is reliable
- Ensure no dispute risk
3. Calculate edge
- If true probability is 99.95% and price is 99.7¢
- Edge = 0.25% (0.9995 - 0.997)
- Minimum edge: 0.1%
4. Size position
- Can risk more on near-certain outcomes
- Position size: $100-500 per trade
- Deploy across 20-50 markets simultaneously
Daily Workflow
- Morning (10 min): Scan markets resolving today
- Filter: Show only markets at 99.5%+ probability
- Verify: Check if outcome is truly certain
- Buy: Place 5-10 small positions ($20-100 each)
- Evening: Markets resolve, collect 0.1-0.5% per winner
- Repeat: Do this daily across 200-300 markets/year
Risks & Challenges
1. Black Swan Events
The 15% loss rate shows that "impossible" outcomes happen:
- Need 200+ trades for edge to emerge
- One $1,000 loss wipes out 200 × $5 wins
- Must diversify across many small positions
2. Oracle Risk
Markets at 99.9% can still resolve incorrectly:
- Disputed outcomes
- Oracle errors
- Ambiguous resolution criteria
- Market manipulation
3. Opportunity Cost
Capital locked in 0.1% returns vs other strategies:
- $5,000 deployed for 0.1% = $5 profit
- Same $5,000 in 50-50 market with 10% edge = $500 profit potential
- But: Near-certain strategy is much lower risk
4. Platform Fees & Gas
At 0.1-0.4% edge, fees matter:
- Ethereum gas fees: $5-20 per trade
- Polymarket fee: 2% on winnings (eats into edge)
- Need larger positions ($200+) to overcome fees
