OG prediction market review: Crypto.com's sports-first app, its fees, states and new-user offer

Disclosure: PredictionsMarket.com earns commissions when readers sign up for OG, Kalshi or Gemini through links on this site (see our affiliate disclosure). This review is based on OG's own pages and published third-party reviews. Not investment advice. Prediction trading involves risk and may not be appropriate for all.

This OG prediction market review covers what OG is, why someone might choose it, what it charges, how money goes in and out, where it is available and the new-user offer. Every fee and limit below comes from OG's own help centre, read on October 29, 2026. Where third-party reviews disagree with OG's pages, we follow OG's pages and say so.

OG prediction market review: what OG is

OG (OG.com) is a prediction market app from Crypto.com. Crypto.com moved its prediction business into the standalone app on February 3, 2026, ahead of the Super Bowl, as Covers reported at the time.

OG's US introduction page says its event contracts are offered by North American Derivatives Exchange, Inc. (NADEX), which does business as OG.com Prediction Markets, a CFTC-regulated exchange. The og.com footer adds that trading also runs through a CFTC-registered futures commission merchant, Foris DAX FCM LLC. Covers and some third-party reviews use its earlier name, Crypto.com | Derivatives North America (CDNA). Each contract pays $1 if its outcome happens and nothing if it does not, and you can close a position before settlement when there is a buyer on the other side.

Why someone would choose OG

• A sports-first layout. OG's market guide leads with winner, spread and total markets, terms sports fans already know. BettingUSA calls the app fast and clean, and CryptoSlate says the order ticket is easy to follow.
• Combos. OG's Combo feature joins up to 20 sports legs into one position, including selected live games and same-game combos in selected leagues. Every leg has to be correct for the combo to pay.
• Crypto.com accounts carry over. If you already have a verified Crypto.com account, OG links the two, so one login works on both and identity verification is not repeated.
• No fee when a position settles. OG charges when you open or close early, not at settlement.
• Many ways to fund. Bank, debit card, Apple Pay, Google Pay, PayPal, Venmo, wire and crypto deposits are all described in OG's help centre.
• Community features. OG runs leaderboards of its top 100 users, and BettingUSA describes live chat on event pages.

OG fees

OG trading fees for US customers, from OG's help centre, last checked October 29, 2026

Action	Most markets (sports, politics and others)	Crypto, FX, commodities, equity indices
Open a position, order fills at once (taker)	0.07 × contracts × price × (1 − price)	$0.02 per contract
Open a position, resting order fills later (maker)	0.0175 × contracts × price × (1 − price)	$0.02 per contract
Close before expiry	Same formula as opening	$0.02 per contract
Position settles	No fee	No fee

Because the formula multiplies by price × (1 − price), the fee per contract is largest near 50 cents and shrinks toward the extremes. Several third-party reviews list a flat $0.02 per contract on everything; OG's fees page now applies that only to the financial markets in the right-hand column. OG also offers limit orders (not for combos), which some older reviews say it lacks. OG's market guide says payouts, including fees, are shown before you place a trade. Our Kalshi and Polymarket fee calculator does not cover OG.

Funding and withdrawals

• Linked bank account through Plaid: funds usable within minutes, but withdrawals are held for 7 business days after such a deposit.
• Debit card, Apple Pay, Google Pay: $10 minimum; OG charges no fee, though your card issuer may.
• Wire: $1,000 minimum, no OG fee.
• PayPal and Venmo (US outside New York): $10 minimum and no OG fee, per its PayPal and Venmo pages.
• Crypto (US outside New York): deposits through Mesh are converted to US dollars; OG adds no fee beyond network fees.
• Withdrawals: ACH with no OG fee, or real-time payment to a participating bank for a 1.5% fee.
• New York: OG's New York funding pages cover bank, wire and debit card deposits only.

Where OG is available

OG's US introduction page says it "is currently available in all U.S. states, however, certain event contracts offered through OG.com may be unavailable in certain U.S. states." OG's help centre has separate pages for New York accounts. Third parties disagree: BettingUSA says trading is unavailable in Arizona and New York and lists seven states where sports contracts are blocked, while CryptoSlate's review contradicts itself on New York. We follow OG's statement, and the app shows which contracts you can trade where you are.

New-user offer

OG's welcome offer reads: "Trade $25, get $50 in rewards." A second offer reads: "Trade $10, get $10 in rewards." Details are on our OG sign-up offer page and our trade $10, get $10 offer page. OG sets the terms, they vary by jurisdiction, and the version that applies to you is the one shown under Promos in the app.

Our account

We opened an OG account for this review. Sign-up was standard for a US-regulated venue, and we have nothing further to report first-hand.

Downsides and what we could not verify

• Liquidity. OG's liquidity page says quotes can disappear near expiry and during live play, so an early exit is not always possible.
• Thinner outside sports. CryptoSlate and BettingUSA both find fewer non-sports markets than on the largest venues.
• Combos are sports-only and exclude futures.
• Not verified: app store ratings, the deposit card fees one third party reports (OG's pages say it charges none), and the state-by-state sports restrictions third parties list.

Our Kalshi review and Gemini Predictions review cover each venue in depth, and the prediction market platform comparison puts them side by side with the others.

Who OG suits

OG suits sports fans who want spreads, totals and multi-leg combos in an app that reads like a sportsbook, and existing Crypto.com customers who want to skip a second identity check. Outside New York, it suits people who fund with PayPal, Venmo or crypto. It suits less well anyone who mainly follows politics, economics or culture markets, or who needs to exit large positions in thinly traded markets.
