Kalshi Fees Overview
- Fees Structure: OG charges fees ranging from $0 to $0.20 per contract, depending on how trades are executed and settled. It uses a two-part fee model: an Exchange Fee applied to all trades and a Technology Fee applied only to $10 and $100 contracts at both entry and exit.
- Key Benefit: Transparent, market-driven pricing with no bookmaker interference, allowing users to trade based on true market sentiment while maintaining relatively competitive fees.

OG is a legal, regulated prediction market app that is live in every U.S. state except Arizona and New York.
Users on OG can trade contracts based on sports and other real-world outcomes, from politics to weather and more.
OG’s fees change based on the size of the contract and how long you keep the position open. A $1 contract costs $0.02 to buy, plus another $0.02 if you sell before settlement. Larger contracts, such as $10 and $100 contracts, come with an added technology fee.
You can use my OG fee calculator to see what you’d pay based on order type, contract count, and share price.
OG Pricing & Fees
On OG, pricing comes from the market itself. Users buy and sell contracts based on what they think will happen, and the contract price reflects where buyers and sellers are willing to trade.
Sportsbooks work differently because they set the odds first and build in their cut. OG does not price markets that way, since the number moves with trader demand instead of a sportsbook line.
Fees on OG range from $0 to $0.20 per contract, depending on contract size and how the trade is closed. Even after fees, OG can still offer better pricing than traditional sportsbooks on the same game or event.
OG follows Crypto.com’s pricing model for prediction markets.
There are two possible fees, and the one you pay depends on the size of the contract:
- Exchange fee: applies whenever you open or close a position early.
- Technology fee: applies only to $10 and $100 contracts and is added on both the buy and sell side.
You can see the full fee breakdown by contract size in the table below.
| Action | $1 Contract | $10 Contract | $100 |
|---|---|---|---|
| Opening a position | $0.02 exchange fee | $0.10 exchange fee + $0.10 technology fee | $1.00 exchange + $0.99 tech |
| Closing a position before the game ends | $0.02 exchange fee | $0.10 exchange fee + $0.10 technology fee | $1.00 exchange + $0.99 tech |
| Position settles “in the money” (you were right) | No fees | $0.10 exchange fee only | $1.00 exchange + $0.99 tech |
| Position settles “out of the money” (you were wrong) | No fees; you simply lose your stake | No fees; you simply lose your stake | No fees; you simply lose your stake |
Detailed Fee Analysis
OG operates a fixed-fee model based on contract notional size ($1, $10, $100). That makes costs easy to predict, but it’s not very flexible for high-volume traders. Fees are set by tier, not by where the contract is priced, so you know the bill up front, but you can’t really optimize it through timing or by adding liquidity.
In real use, the effective cost depends mostly on the tier and how long you hold the position. On $1 contracts, fees are usually the most forgiving on a percentage basis.
If you buy and hold through settlement, the total cost is typically around ~2% of the max payout, while a round-trip open-and-close often lands closer to ~4% because fees hit both entry and exit.
On $10 and $100 contracts, round-trip costs usually sit in the ~3%–4% range.
However, these tiers can get more efficient if you hold to resolution and the position settles in the money. In that case, effective fees often drop to ~1%–2%, partly because the technology fee may be waived at settlement, where larger tiers can beat the $1 tier on percentage cost.
The fee structure clearly favors buy-and-hold over constant churn. Every entry and exit adds friction, so scalping or frequent repositioning can quickly rack up costs, regardless of tier. If you’re the type to trade every little move, those fees start to feel like a tax.
One upside is that fees don’t change with probability. Trading near 50¢ doesn’t cost more, unlike platforms that price fees off P × (1 − P). That keeps it simple and avoids surprise fee spikes on coin-flip markets.
In my Crypto vs Kalshi article, I compare Crypto’s fixed fees (the same framework OG runs) against Kalshi’s fee structure, which should also help you size up OG.
Overall, $1 contracts are often the safest for casual trades or shorter holds. $10 and $100 contracts can be more cost-efficient if you trade less frequently and let winners run to settlement. The model is transparent and retail-friendly, but it rewards patience more than constant action.
