What is OG.com?

OG.com is a CFTC-compliant technology that offers access to a CFTC-regulated prediction market trading platform where users can potentially profit from their insights on sports, politics, economics, and culture. Not all markets may be available in every state; some have specific restrictions barring any sports predictions, for example.

Predictions are event contracts that are derivative products offered by North American Derivatives Exchange, Inc (NADEX), which does business as OG.com Prediction Markets (OG.com), a CFTC-regulated exchange through OG.com technology.

When was OG.com created?

OG.com's roots began in 2008, when their platform was originally called "HedgeStreet." The platform became one of the first CFTC-regulated venues built for trading real-world outcomes and later became NADEX, which was acquired by Crypto.com in 2024.

Once acquired by the crypto platform, NADEX became the first CFTC-regulated exchange to list sports event contracts, which put prediction markets in the spotlight. In 2026, Crypto.com officially launched OG.com, which has since caused many big names in finance and sports gaming to follow suit with a licensed exchange (Robinhood, DraftKings, FanDuel, and many others). 

Platform details and requirements

  • Users must be 18+ in eligible states (19+ in Alabama and Nebraska)
  • Must complete KYC (Know Your Customer) verification
  • Accepted deposit methods: ACH bank transfer, wire bank transfer, PayPal, Apple Pay, Google Pay, debit cards, or Venmo
  • Accepted withdrawal methods: ACH bank transfer or RTPs (Real-Time Payments)

How OG.com works

Like most prediction markets, OG.com operates around a single "Yes" or "No" answer for each question. In relation to sports, a future prediction on a team to win a sports championship would be framed around the question "Which team will win the trophy/championship?" Then, every team would have a "yes" or "no" option, followed by a percentage that users believe they will or won't win based on trading.

For specific sports, most prediction markets take predictions for traditional game lines (moneyline, spread, point total), or player props for specific stats (points, RBIs, goals, etc.). Profitability on certain lines fluctuates with how many users are taking lines at a given time. Typically, the percentage seen on a line is how many cents it costs per contract. For example, if the Buffalo Bills have a 56% chance to beat the Kansas City Chiefs in a given game, each contract on the Bills to win would be valued at around 56 cents each.

Setting up your account

If you’re new to OG.com, here’s a step-by-step guide to get set up and ready to trade. 

  • Head to OG.com's site or app and register
  • Provide your name, address, date of birth, phone number and email
  • Get verified through the KYC process (this also confirms you’re in an eligible state)
  • Pick a funding method — debit card, Apple/Google Pay, wire transfer, etc.
  • Deposit (many welcome offers key off a minimum deposit)
  • Start browsing markets

Trading on OG.com

Say you’re looking at futures markets ahead of the NFL season and “NFL Champion 2027” catches your attention. The board currently has the 49ers favored at 17 percent, the Bills close behind at 14 percent, and the Rams at 13 percent. However, a user may have a desire to predict more of a sleeper team to win for more profitability.

A team like the Detroit Lions that missed the playoffs last season and has an atrocious defense could catch a user's eye. They can score a lot of points; if they get their bad defense sorted out, they could be a force to be reckoned with. Backing “Yes” on Detroit currently costs $0.06 per contract, which is the market’s way of saying it thinks there’s roughly a 6 percent shot of that happening. 

If a user commits $15 to the position, they would net around 250 contracts at that price. Win, and those contracts convert to around $250, which is a $235 gain before OG.com takes their 2-cents-per-contract cut ($5, in this case). Lose, and the $15 is gone. 

Then, a situation happens that could inhibit the user's future prediction. News breaks that star Jahmyr Gibbs fell victim to an injury in practice, which will force him out for an extended period of time. It’s a single report from an obscure source, not yet a full-blown story, but it’s enough to make a user nervous about holding the position. This is where the exchange format pays off. 

Because the news hasn’t spread widely, there isn’t a rush of sellers pushing the price down hard. Still, it’s moved enough that your contracts are now trading around $0.05. The user decided not to wait and see, so they sold and pocketed $12.50 after the fees for only a $2.50 loss on their original stake. Had the user held, and Detroit ultimately missed the Super Bowl, they would have lost the full $15 instead.

DON'T FORGET: New users can trade $10 to get $10 in investment funds with promo code TSN25

Is OG.com legal?

Yes, OG.com is federally legal. All event contracts are offered by North American Derivatives Exchange, Inc (NADEX), which does business as OG.com Prediction Markets (OG), a CFTC-regulated exchange through OG.com technology.

Some states, however, may limit which markets are available for users depending on their state gambling laws. Other markets on politics, finances, etc. may still take predictions for users in these states; only sports markets have been giving some users problems.

How OG.com differs from sportsbooks

The surface-level experience — picking a game, picking a side, watching to see if you cashed — can feel similar between OG.com and a sportsbook. Underneath, though, almost everything about how a trade gets built, priced and settled works differently.

Who you're trading against

A sportsbook takes your bet directly; lose, and your stake becomes the house’s revenue. OG.com never takes that position — it just connects you with another trader who wants the opposite outcome, and collects a small commission for making the match happen.

Pricing and implied odds

Sportsbook lines come from professional oddsmakers, with a vig quietly built in so the house profits regardless of outcome. OG.com has no oddsmaker at all — every price on the board is just wherever traders have agreed to transact, moving in real time as news breaks and positions shift.

Trading flexibility

A sportsbook bet is typically locked the moment you place it, unless the operator happens to offer a cash-out and decides to extend it to you. OG.com doesn’t gatekeep that decision — you can exit or add to a position whenever the market’s open, full stop.

Types of markets

Sportsbooks stick to sports. OG.com does too (along with other market types depending on which state a user resides in), but the exchange format means you’re not stuck with a single number for any given outcome. Users can name their own price and see if the market bites.

Technology and currency

A sportsbook is a closed system: it holds your funds and controls the ledger. OG.com, as a CFTC-cleared exchange, settles trades the way other regulated derivatives markets do, with U.S. dollars as the default currency (crypto funding is available but optional).

Legal status and regulation

Sportsbooks answer to whichever state they’re licensed in, which is exactly why legal sports betting looks so different from one state line to the next. OG.com answers to a single federal regulator instead, which is how it ends up live in states where a traditional sportsbook may not be able to operate at all.

Limits and restrictions

Plenty of sportsbooks quietly cap or ban customers who win too often. On an exchange, there’s little incentive to do that — your winnings come out of another trader’s pocket, not the platform’s, so a sharp customer isn’t a threat to the house in the same way.

OG.com pros and cons

When deciding which prediction market platform to use, it only makes sense to go through the pros and cons. Let’s take a look at the pros first. 

  • Real-time, market-driven pricing
  • No edge for “the house”
  • Back-and-lay trading flexibility
  • Modern UI with easily accessible markets
  • No limits on winning traders
  • Federally regulated nationwide (except Arizona and New York)

What are some of the cons associated with the OG.com platform?

  • Restricted in Arizona and New York
  • Regulatory landscape for sports event contracts is still evolving
  • Liquidity can be thinner on less popular markets
  • Learning curve around back/lay exchange mechanics for bettors used to sportsbooks
  • Limited track record as a real-money, federally regulated exchange
  • Not many withdrawal methods available
