Crypto.com, OG.com and the exchange behind them
Crypto.com owns a CFTC-regulated exchange, North American Derivatives Exchange, Inc. It has been a designated contract market since 2004 (it started as HedgeStreet), Crypto.com bought it in 2022, and it also clears its own trades. Crypto.com says it was the first to offer federally regulated sports contracts in the US, in December 2024.
You can trade on that exchange in two places. The Crypto.com app has a Prediction tab, which suits you if you already hold crypto there. OG.com, launched on February 3, 2026, is a separate app built only for prediction markets, and most of the details below come from OG’s help pages. The exchange also powers other apps: FanDuel Predicts added contracts through it in June 2026, and since September 8, 2026 Robinhood sends some football trades there.
Fees
For most markets, takers (whose orders fill straight away) pay 0.07 × contracts × price × (1 − price), and makers (who set a price and wait) pay a quarter of that. On a $100 trade at 50¢, 200 contracts cost $3.50 in fees as a taker or $0.88 as a maker. That’s the same taker fee as Kalshi. Crypto, FX, commodity and stock-index contracts are simpler at $0.02 per contract to open or close, and there’s no fee when a contract settles.
Deposits and withdrawals
This is where OG stands out. You can deposit from $1 by ACH, from $10 by linked bank, debit card, Apple Pay, Google Pay, PayPal or Venmo, and from $1,000 by wire. Crypto can be converted to dollars in seconds to 20 minutes. OG doesn’t charge for any of these.
There’s one catch with linked-bank deposits. The money is usable within minutes, but you can’t withdraw it for 7 business days. ACH withdrawals are free from $1, and if you need the money fast, RTP withdrawals arrive within minutes for a 1.5% fee.
What you can trade
OG covers sports (winners, spreads, totals and player stats), politics, economics, culture, crypto, financials, commodities and climate. Combos, where every pick has to win, take 2 to 8 picks but only work on sports, and same-game combos are limited to some leagues. You can close a combo early.
Sign-up offer
OG’s welcome offer has been live since June 24, 2026. You place one trade priced under 80¢ that settles within 7 days of verifying your ID. The reward amount only appears in the app, and Crypto.com’s own pages have given different figures over the year, from up to $500 at launch to “up to $10” on the current Google Play listing. Rewards expire after 30 days. The refer-a-friend offer pays you and your friend $10 each, but you can’t use it together with the welcome offer.
Where it’s available
You need to be 18. OG says it’s available in all US states, including New York since June 13, 2026, but that some contracts may not be offered in every state. Some review sites list sports restrictions in a handful of states, but Crypto.com hasn’t confirmed those, so check the app before you deposit.
The apps and support
Both apps rate well. The Crypto.com app has 4.7 on the App Store from 335,000 ratings and 4.4 on Google Play from 693,000. OG is newer, with 4.5 from about 1,600 ratings on iPhone and 4.3 on Android. Support is in-app chat (or chat.og.com), and OG lets you exclude yourself, with a 7-day cooling-off period before you can undo it.
Who it suits
Crypto.com is a strong choice if you want to start small, move money in and out quickly, or already keep crypto in the Crypto.com app. If you want a clear sign-up bonus you can see before you download, look at Polymarket or Kalshi.
