3. Fee Structure

Standard Fees

Kalshi charges fees on expected earnings (not position size):

Taker fee: ~7% of expected profit (varies by market)
Maker fee: Some markets have maker rebates, others charge fees
No fee on losing trades (only pay fee on winning side)

Fee Calculation Example

If you buy YES at $0.50 and win $1.00:

Profit = $0.50
Fee = ~$0.035 (7% of $0.50)
Net profit = $0.465

Special Considerations

Some markets have fee waivers for limited periods
High-frequency crypto markets may have adjusted fees
Check fee_waiver_expiration_time via API

7. Current Market Observations (Feb 5, 2026)

15-Minute Markets (as of research time)

Market	Yes Price	Implied Prob	Volume
BTC 15m Up	~14% (6.74x)	Low	$15,635
ETH 15m Up	~12% (7.85x)	Low	$1,965
SOL 15m Up	~9% (10.45x)	Low	$2,482

Note: 15-min "Up" typically prices at low probability (10-15%) because it's essentially asking "will it be UP from current price" - which over 15 minutes is roughly a coin flip minus the spread.

Hourly Markets (Higher Volume)

Market	Sample Strike	Volume
BTC 5pm EST	$67,000+ @ 44%	$912,309
BTC Tomorrow 5pm	Multiple strikes	$3.2M
ETH 5pm EST	$1,970+ @ 53%	$193,913

8. Strategy Ideas for 15-Min Scalping

Strategy 1: Volatility Momentum

Monitor BTC spot volatility (use external feeds)
When volatility expands, bet on continuation in 15-min markets
Risk: Low liquidity in 15-min markets

Strategy 2: Mean Reversion on Hourly

Use hourly markets instead (more liquid)
When BTC moves sharply in one direction, bet on partial reversion
Target strikes that overshoot/undershoot fair value

Strategy 3: Spread Capture

Place maker orders on both sides of the book
Capture bid-ask spread when prices oscillate
Works better in higher-volume hourly markets

Strategy 4: News/Event Scalping

Monitor for crypto news (ETF flows, regulations, whale movements)
Enter 15-min or hourly markets before settlement
Exit or hedge before event outcome

Strategy 5: Cross-Market Arbitrage

Compare Kalshi probabilities with Deribit options or Polymarket
If Kalshi prices diverge significantly, arbitrage the difference
Requires fast execution and multi-platform access

9. 🕐 Optimal Entry Timing Research (Feb 2026)

The Core Problem

When entering a 15-minute window bet, there's a tradeoff:

Too early (min 0-3): High payout potential but weak signal (essentially noise)
Too late (min 12-14): Strong signal but Kalshi has already repriced efficiently

The Lag Effect = Your Edge

Kalshi market makers reprice based on observed BTC movement, but with a 1-3 minute lag. This lag creates a window where you can have better information than the current Kalshi price reflects.

Window Phases Analysis

Minute	Signal Quality	Kalshi Efficiency	Tradeable Edge
0-3	Weak (50-55%)	Low (near 50/50)	❌ No edge
4-7	Moderate (55-70%)	Lagging reality	✅ BEST
8-10	Strong (65-80%)	Catching up	✅ Still viable
11-14	Very strong (75%+)	Efficient	❌ No edge left

EV Modeling

Expected Value = P(correct) × Payout - P(wrong) × Loss - Fees

Sweet Spot Example (Min 6):
- Our signal: 68% confident BTC continues UP
- Kalshi YES: $0.55 (55% implied)
- If right: Win $0.45 × 0.68 = $0.306
- If wrong: Lose $0.55 × 0.32 = $0.176
- Gross EV: +$0.13 per dollar
- After 7% fee on wins: +$0.11 ✅

Late Entry Example (Min 12):
- Our signal: 78% confident
- Kalshi YES: $0.76 (76% implied)  
- Edge: 2% → Negative after fees ❌

Minimum Edge Requirements

Threshold	Rationale
10% minimum edge	Overcomes ~7% fees + ~3% spread
15% ideal edge	Comfortable profit margin
20%+ strong edge	Rare but very profitable

Entry Decision Rules

ENTER when ALL true:

Time is minutes 4-10 of the window
Signal score ≥ 60/100 (clear direction)
Edge ≥ 10% (our probability - Kalshi implied)
Position size per Kelly-lite formula

SKIP when ANY true:

Minutes 0-3 (too early, noise)
Minutes 11-14 (too late, efficient)
Edge < 10% (fees eat the edge)
Signal score < 50 (no clear direction)

YES vs NO Decision

BUY YES when:

Our technical signals point UP
BTC has moved UP from window open (+0.15%+)
Kalshi YES price < Our UP probability
Edge ≥ 10%

BUY NO when:

Our technical signals point DOWN
BTC has moved DOWN from window open (-0.15%+)
Kalshi NO implied < Our DOWN probability
Edge ≥ 10%

Alert Format

🚨 BUY [YES/NO] NOW
Edge: XX%
Confidence: XX%
Window closes in Y min

Key Insight

The edge exists because Kalshi prices lag real BTC movements by 1-3 minutes. By minute 11+, the lag is gone and prices are efficient. The sweet spot is minutes 4-10 where your technical signals can see something Kalshi hasn't fully priced in yet.

9. Data Sources for Backtesting

Kalshi Data

API: Historical trades via /trades endpoint
Candlesticks: /market/{ticker}/candlesticks
Research portal: https://research.kalshi.com

External Crypto Data (for correlation)

Binance API - BTC/USDT spot prices
CoinGecko - Historical prices
Glassnode - On-chain metrics
TradingView - Charting with indicators

Backtesting Approach

Pull historical Kalshi market prices (candlesticks)
Pull corresponding BTC spot prices
Calculate implied probabilities vs. actual outcomes
Identify systematic mispricings

10. Key Risks & Considerations

Liquidity Risk

15-min markets have lower volume (~$15K vs $900K for hourly)
Wide bid-ask spreads (expect 3-5% spreads on 15-min)
Slippage on larger orders

Timing Risk

Markets close before settlement (can't trade at the last second)
Settlement uses specific price feeds (check rules for each market)

Regulatory

Kalshi is CFTC-regulated (legitimate exchange)
US residents only for most products
Winnings are taxable

Fee Impact

At 7% fee on profits, need >7% edge to be profitable long-term
Frequent small trades compound fee drag
