4casters Promo Code 2026: 25 4C Cash on a $50 First Purchase
Lay $110 to win $100 at a sportsbook and the house keeps roughly $4.55 of every $100 that moves through that market, whoever wins. 4casters takes that seat away. You trade against another user, you can name your own price, and the exchange charges 1% on a bet you take and nothing on an offer you post.
The short answer on a 4casters promo code: there is no code to type, and the offer depends on which version you can open. The exchange at 4casters.io is closed to US citizens. US players get 4CX, a separate sweepstakes platform live in 40 states for anyone 19 or older. Sign up through our link and registration credits 100 Gold Coins and 2 4C Cash, then a first purchase of $50 or more adds 25 4C Cash on top. Our betting promo codes page tracks the other platform offers we follow.
We registered a 4CX account ourselves, and the starter coins landed before we had funded anything, so we worked the board first and made the money decision second. On the exchange side, we went through the order books game by game and read the API changelog, which says more about who 4casters is built for than any landing page. This fall alone it shipped fill-or-kill orders in August, long-lived API keys on October 25, and per-account order limits enforced from November 2. 4CX shares the name but not the mechanics, and this overview judges each on its own terms.
Weighing the whole category? Our betting exchange reviews put 4casters next to the other no-house options we cover.
What Is 4casters? A Peer-to-Peer Exchange Built for Professionals
4casters is a peer-to-peer sports betting exchange. No house sets the line or profits from it. You either take a price another user has posted or post your own and wait for someone to match it. The platform launched in 2021 and says it has handled over $1 billion in wagers since.
It is upfront about who it serves. The company says it has always catered to professional bettors and pitches the product as the simplicity of a sportsbook with the robustness of an exchange. One account carries both views. Sportsbook view puts 36 main market bet types on a single screen. Exchange view opens the full bid and ask ladder, with several prices and the money available at each. The switch is cosmetic, so nothing is locked behind either one.
The pro lean goes past the interface. 4casters publishes a public API: a REST API for account data, market lookups and batch orders, a live connection for low-latency order placement, and a streaming feed for orderbook ticks and your own fills. Since October 25, a program can sign in with an API key instead of your site password. Each key can be locked to the IP addresses you choose, given an expiry, and revoked on its own, while withdrawals, password changes and two-factor settings still require a signed-in website session.
The board runs wider than the headline sports. Alongside NFL, college football, MLB, soccer, WNBA, tennis and fighting, you get CFL markets and first-half NFL lines. A single MLB game splits into main markets, player markets, total strikeouts, home runs and total bases, with a search bar across props, players and games. Sportsbook view also flags markets where the top price carries a limit above $2,000, a quick filter for telling a real number from a token one.
The boundary that matters most is geographic. You cannot use 4casters from inside the United States or as a US citizen, so the exchange is for international bettors. US players get 4CX instead, which runs on a sweepstakes model with Gold Coins and 4C Cash rather than direct cash trading.
How 4casters Works: Setting Your Own Price
The core action is posting an offer. Pick a side, enter the odds and the risk you want, and the offer sits in the market until someone takes the other side. Post Eagles -7 at +106 and another user can take Vikings +7 at -106. You are naming a number instead of accepting one, and an offer nobody takes costs you nothing.
Commission is where the model earns its keep. You pay 1% on a bet you take and 0% on an offer that gets matched, and MLB moneylines drop to 0.75%. On a loser the fee comes off the smaller of your risk or your potential win, and on a winner it comes off what you won, so risking $50 to win $100 at +200 costs 50 cents if it loses and a dollar if it wins. Apply that to a coin flip. Take a posted +100 and you are effectively risking $101 to win $99, roughly a -102 bet, where the same side at a book usually costs -110. A setting shows every price with commission baked in, so the board can read like a normal sportsbook.
Clicking any price opens one panel that does both jobs. You see the ladder for that market on both sides, enter a risk or a to-win figure, and either take what is posted or create your own offer without leaving the screen. Games carry rotation numbers the way a Vegas board does, with traded volume under every matchup.
Alternate numbers live in the same view. A strip above each market moves the spread or total, and a plus button adds a number that is not there yet. On a Chiefs at Dolphins board we flipped between +7.5, +9.5, +10.5 and +11.5 on the spread and 44.5 through 47.5 on the total, each with its own order book.
Two features go further than most exchanges. Any user can create a custom spread or total, so if the market has not hung your number, you post it yourself. And the order book shows real depth. On a Rays at Yankees board, each market carried four price levels with the money available at every one, and the game showed over $63,000 in matched volume while other games on the same slate sat under $4,000. That gap is the most useful thing on the screen, because it tells you where the liquidity is before you commit.
Balance behaves differently from a sportsbook. Available funds are calculated against your worst-case outcome per game, so hedged positions on the same event tie up far less than the sum of both stakes. The My Bets screen splits into positions, pending bets, open offers you can still edit, and graded results.
How to Sign Up at 4casters and 4CX
Which link you use depends entirely on where you are. Both take a couple of minutes.
If You Are Outside the United States
Go to 4casters and create an account with a username, email and password.
Fund with cryptocurrency. The platform supports BTC, ETH, USDT and USDC on ERC-20, and non-USDT deposits convert to USDC.
Choose sportsbook view or exchange view in settings, and toggle commission-inclusive odds if you would rather read prices the familiar way.
Take a posted price, or create your own offer and wait for a match.
If You Are in the United States
Go to 4CX. There is no code to type anywhere. The offer is attached to the link itself, so arriving through it is what qualifies you.
Enter a username, email and password, and confirm you are 19 or older.
Signing up credits 100 Gold Coins and 2 4C Cash to start.
Make a first purchase of $50 or more and 25 4C Cash lands on top of it.
Registering on 4CX took us about two minutes, and the 100 Gold Coins and 2 4C Cash landed on the account immediately, which is enough to click around the board before deciding whether to fund anything. The 4casters side asks for no more information than that either, though funding it means moving crypto.
The 4CX lobby is organised by sport across NFL, college football, MLB, fighting, soccer, WNBA, tennis and props, with a custom market builder alongside them.
Why Sign Up for 4casters in 2026?
The case is price, and the math is short. Push $50,000 through standard -110 markets over a season and roughly $2,275 of that handle is house margin. Take the same volume at posted prices on 4casters and the commission comes to around $500, and any offer of yours that gets matched costs nothing. Posted prices still carry whatever gap other traders leave between them, but the fee is a fraction of what a book builds in.
Second, nobody is grading you. There is no house on the other side deciding your account is too sharp, which is the quiet reason serious bettors drift to exchanges after getting limited elsewhere. If you move that volume with code, the API is built for it: an orders heartbeat cancels your resting offers if your connection drops, fill-or-kill orders match in full or not at all, and the order limits are published. A standard account gets 20 orders a second with bursts to 200, an advanced account gets 150 a second, and cancels and edits never count, so you can size a strategy before you build it.
Third is control. Between posting your own odds and building custom spreads and totals, you are not stuck with the numbers someone else hung. Pair it with an odds screen and the workflow is simple: find where the market sits, check the 4casters ladder, then take the price or post the one you want. Our best sports betting tools rankings cover the screens worth running alongside it.
The US answer is narrower, and worth being straight about. 4CX is a sweepstakes platform, so it runs on Gold Coins and 4C Cash rather than dollars traded against another user, and it does not carry the commission structure that makes the exchange interesting. What it does offer is a board across the major US sports with a custom market builder, in 40 states, at 19 and up rather than 21. The free starter coins let you try that board before spending anything, and our link adds 25 4C Cash to a first purchase of $50 or more. If you would rather trade peer to peer in dollars on a CFTC certified prediction market, our Novig review covers that route, where code BETSMART adds $25 in trade credits on a $10 deposit.
4casters Review: Pros and Cons in 2026
The pricing core is strong, and the conditions attached to it are just as real. Both belong on the table before you fund anything.
Pros
1% commission, and 0% on offers. You pay only on bets you take, and MLB moneylines drop to 0.75%. Against roughly 4.5% of hold on a standard -110 market, that gap is the whole pitch.
You set the price. Post the odds and stake you want, and create custom spreads and totals when the market has not hung the number you are after.
Order book depth you can see. Multiple price levels per market with the money at each, plus matched volume per game, so you know where the liquidity is before you commit.
An API built for automated trading. REST and streaming access to the same order book, fill-or-kill orders since August, and since October 25 API keys you can restrict by IP, set to expire and revoke one at a time, so a bot never needs your password.
Prop coverage with real structure. Strikeouts, home runs and total bases each get their own market on a single game, plus CFL and first-half NFL lines.
Sportsbook view or exchange view. Same account, same functionality, and commission-inclusive pricing can be toggled on so the board reads like a book you already know.
No house with a reason to limit you. Your counterparty is another trader, not a book managing its exposure to profitable accounts.
Cons
US citizens cannot use the exchange. Not from inside the country, and not as a citizen abroad. 4CX serves US players, but it is a sweepstakes product rather than the same trading platform.
Crypto only. BTC, ETH, USDT and USDC are the funding rails, which rules the exchange out for anyone unwilling to hold crypto.
Withdrawals are approved by admins. The documentation says so directly and warns that anyone needing instant withdrawals should look elsewhere.
Liquidity is uneven, and the gap is wide. A Chiefs at Dolphins board showed over $47,000 traded and tens of thousands behind the moneyline, while a Padres at Dodgers home run market the same night had traded about $4,500 in total. The top price can be real money on a marquee game and a token amount in a niche prop.
The learning curve is real. Offers, dynamic balance and worst-case risk calculation all behave differently from a sportsbook, and the interface assumes you want that.
For US readers, 4CX is the version you can open today. Registering through our link credits 100 Gold Coins and 2 4C Cash right away, and a first purchase of $50 or more adds 25 4C Cash with no code required. If trading in dollars on a CFTC certified prediction market matters more to you, compare it against Novig before choosing.

An exchange gives you the price, not the reason to take it. These three cover the other half of the job, and all fit the kind of bettor an exchange is built for.

Why 4casters Matters in 2026
4casters matters because it takes the house out of the transaction and charges very little to do it. One percent on a taken bet and nothing on a matched offer turns a -110 coin flip into something closer to -102. The visible order book, custom markets and an API that added keyed access and published order limits this fall make that price usable at volume, not just on paper.
The conditions are just as concrete. The exchange is closed to US citizens, it runs on crypto, and withdrawals wait on approval. For international bettors moving volume who care more about price than convenience, it is a serious platform worth an account. For US readers, 4CX is the door that is open, and it deserves to be judged as the sweepstakes product it is rather than a stand-in for the exchange.
Outside the US, with price driving your results, 4casters earns the account on its commission structure alone, and keyed API access makes it workable at scale. Inside the US, 4CX is the one you can open: sign up through our link, test the board with the free 100 Gold Coins and 2 4C Cash, and a first purchase of $50 or more adds 25 4C Cash with no code to enter. Read the funding and withdrawal terms before you move money on either.
