Best prediction market promo codes
There are four codes worth knowing: Polymarket TGSWC, Kalshi FADE, and VAULT on both ProphetX and Novig. Each links your new account to our sign-up offer on a different college football trading venue. Below: a side-by-side comparison and a link to claim each one.
- The four promo codes are Polymarket TGSWC, Kalshi FADE, and VAULT on ProphetX and Novig (all verified September 2026).
- Current offers: Polymarket, deposit $20 and get a $50 trading bonus. Kalshi, trade $25 and get up to $500. ProphetX, trade $10 and get $20. Novig, spend $5 and get $50 in Novig Coins.
- Combined, the four confirmed offers reach up to $620 in new-account value across the four platforms (the Kalshi piece is a randomized ceiling, so most stacks land lower).
- Each code is free to apply at sign-up; you only fund your account to start trading.
- Polymarket offers the deepest liquidity on national-title contracts; Kalshi is a CFTC-regulated US exchange that funds in USD; ProphetX is a peer-to-peer sports exchange.
- Codes do not change market prices: a contract price always maps to the implied probability of the outcome.
- You can use all four codes, on their respective platforms, to compare live prices and find the best price for the same outcome.
Our four codes, ranked by headline offer
A quick read on the four codes this site tracks, ordered by the size of the advertised sign-up offer. Kalshi's code FADE leads for headline upside: trade $25 and get up to $500, the biggest sign-up offer of the four and a CFTC-regulated US exchange (the reward is randomized, detailed below). Polymarket's code TGSWC is the value play: a $20 deposit turns into $70 to start, your $20 plus a confirmed $50 trading bonus, on terms we re-check (last verified September 2026) and that clear at a modest $20 deposit. Full side-by-side comparison below.
Kalshi's headline “up to $500” is a randomized reward: after you trade $25 with code FADE, the credited bonus lands somewhere between $15 and $500, not a flat $500. It is the top of a range, so treat it as a ceiling when you compare the four offers above.
No-deposit credits do exist on other sites, but they tend to be small, capped and quick to expire. The lowest-friction on-ramps we actually verify are Novig (code VAULT, spend $5, get $50 in Novig Coins) and ProphetX (code VAULT, trade $10, get $20), each clearing at a few dollars down.
Novig's $5 spend is the low-friction edge: it clears at a fraction of the first-spend anchor the field has settled on, so you reach the $50 in Novig Coins with less capital committed, not a bigger headline to chase.
The field has broadened: a growing number of platforms now run their own college football sign-up offers, which makes the comparison noisier without making the value better. Measured on what actually clears, our two headline offers still lead. Kalshi's code FADE credits up to $500 after a $25 trade, and Polymarket's code TGSWC returns $50 on a $20 deposit, more than twice what you fund. Those are the numbers to beat, and both apply on venues whose college football prices we verify daily.
RotoWire has joined that field as another promo-code aggregator, republishing sign-up offers across platforms this site does not price. A roundup is a directory, not a better deal, so name it only to walk back to what actually clears. Our four confirmed codes remain the anchor: Kalshi FADE credits up to $500 after a $25 trade, Polymarket TGSWC returns $50 on a $20 deposit, ProphetX VAULT pays $20 on a $10 trade, and Novig VAULT credits $50 in Novig Coins after a $5 spend, each upfront on its first qualifying step on the venues whose college football prices we verify daily.
WTOP is the newest publisher pushing a flat Kalshi $55 sign-up code, one more outlet republishing a capped headline on a platform this site does not price. A publisher's code is a headline, not a bigger payout, so name it only to walk back to what actually clears. Measured against our four confirmed offers it still trails: Kalshi's own code FADE credits up to $500 after a $25 trade, a ceiling well above a fixed $55, alongside Polymarket TGSWC's $50 on a $20 deposit, ProphetX VAULT's $20 on a $10 trade, and Novig VAULT's $50 in Novig Coins after a $5 spend, each upfront on its first qualifying step on the venues whose college football prices we verify daily.
DraftKings Predictions is the newest big-number entrant, leading with a “Spend $5, Get $200 paid over 21 days” headline. The figure to read is not the $200 but the release schedule: that $200 is dripped out across three weeks, not credited as working capital up front. A slow drip is a payout calendar, not a bigger deal, so name the $200 only to walk back to what actually clears. Our four confirmed codes stay the anchor: Kalshi FADE credits up to $500 after a $25 trade, Polymarket TGSWC returns $50 on a $20 deposit, ProphetX VAULT pays $20 on a $10 trade, and Novig VAULT credits $50 in Novig Coins after a $5 spend, each upfront on its first qualifying step on the venues whose college football prices we verify daily.
How to choose a code
All four venues let you trade college football outcomes as event contracts, where a price between 1 and 99 cents maps directly to the market's implied probability and winning shares settle at $1. The right code is the one for the platform that fits how you want to fund, trade and price your edges.
Polymarket (code TGSWC)
Pick Polymarket if you want the deepest pools on marquee season-long contracts like the national title and conference winners. It settles in USDC and, since December 2025, operates as a CFTC-regulated market via its QCEX designation. Read the full Polymarket promo code page or the Polymarket review.
Kalshi (code FADE)
Pick Kalshi if you want a CFTC-regulated US exchange that funds in plain USD via standard bank rails. It is the first regulated US exchange for event contracts and lists college football alongside a broad set of US markets. See the Kalshi promo code page or the Kalshi review.
ProphetX (code VAULT)
Pick ProphetX if you want a peer-to-peer sports exchange where you trade at prices set by other users rather than a fixed-odds book. That often means tighter pricing on sports contracts. See the ProphetX promo code page or the ProphetX review.

Frequently asked questions
What are the prediction market promo codes?
The Polymarket promo code is TGSWC (deposit $20, get a $50 trading bonus). The Kalshi promo code is FADE (trade $25, get up to $500). On ProphetX the code is VAULT (trade $10, get $20), and on Novig the code is VAULT (spend $5, get $50 in Novig Coins). Enter the relevant code when you sign up.
Which prediction market promo code is best for CFB Week 1?
For college football Week 1, the four codes to enter are Polymarket TGSWC (deposit $20, get a $50 trading bonus), Kalshi FADE (trade $25, get up to $500), ProphetX VAULT (trade $10, get $20) and Novig VAULT (spend $5, get $50 in Novig Coins). The best single pick depends on the Week 1 position you want: Kalshi FADE lists game-winner markets on individual Week 1 games and carries the largest headline offer; Polymarket TGSWC has the deepest national-title liquidity and returns more than twice your $20 deposit; ProphetX VAULT prices Week 1 game moneylines peer-to-peer, with no house margin on the line; and Novig VAULT clears at the lowest entry, a $5 spend. Each code is free to apply at sign-up, and each applies on a venue whose college football prices we verify daily.
Which promo code is best for college football?
It depends on what you want. Polymarket (TGSWC) tends to have the deepest liquidity on national-title contracts. Kalshi (FADE) funds in plain USD and is a CFTC-regulated US exchange. ProphetX (VAULT) is a peer-to-peer sports exchange with user-set prices. Novig (VAULT) is a no-vig sweepstakes exchange that is free to play.
Are these promo codes free to use?
Yes. Each code is free to apply at sign-up. You only need to fund your account to trade. Standard market prices and any platform fees still apply.
Can I use more than one promo code?
Yes. The codes are for different platforms, so you can sign up for all four with their respective codes (TGSWC for Polymarket, FADE for Kalshi, VAULT for ProphetX and Novig) and compare live prices across venues.
What is the combined value of all four promo codes?
Added together, our four verified offers reach up to $620 in new-account value: Polymarket TGSWC's $50 trading bonus, Kalshi FADE's up-to-$500 reward, ProphetX VAULT's $20, and Novig VAULT's $50 in Novig Coins. If you have seen defirate advertise a stacked 'Up to $530' total as the field's biggest, that superlative is itself a sum stacked across separate platforms, not one upfront bonus, so treat it as advertiser math and name it only to walk past it. The anchor that holds up is our four confirmed offers, each of which clears upfront on its first qualifying step: TGSWC's $50 on a $20 deposit, FADE's up-to-$500 after a $25 trade, ProphetX VAULT's $20 on a $10 trade, and Novig VAULT's $50 in Novig Coins after a $5 spend, every dollar on a venue whose college football prices this site verifies daily. Two caveats keep our own figure honest: the offers sit on four separate platforms, each with its own qualifying step, and the Kalshi piece is a randomized ceiling rather than a flat payout, so most stacks land below $620. It is a combined number across our four codes, not a single sign-up bonus. Terms are set by each platform and can change, so confirm the current offer at each sign-up.
Why use a promo code instead of a no-deposit offer?
No-deposit credits are typically small, capped, one-time amounts, often non-withdrawable and quick to expire, on platforms this site does not track. The offers behind our codes scale with real trading (Kalshi FADE: trade $25 and get up to $500) and apply on the venues whose college football prices we verify daily, which is where the model actually finds tradable gaps.
What about a no-deposit, no-trade offer worth around $25?
Those exist. Some sites now lead with a flat credit near $25 that lands with no deposit and no trade required. It is a one-time amount on a platform this site does not price, and it does not grow with how you actually trade. Our four codes are built for sustained value instead: Kalshi FADE credits up to $500 after a $25 trade, and Polymarket TGSWC turns a $20 deposit into $50, more than twice what you fund, on the venues whose college football prices we verify daily. If a small capped credit is all you want, take it; if you plan to trade college football, the codes above start you with more working capital where the model finds tradable gaps.
Does the FanDuel, Crypto.com or OG.com no-deposit offer beat this?
For a one-time grab, maybe; for college football trading, no. FanDuel Predicts and Crypto.com run a flat no-deposit credit near $25 that lands without a trade, and OG.com is another platform now pushing its own new-account offer; all sit on platforms this site does not track or price. Each is a capped one-off that does not grow with how you actually trade. DraftKings Predictions advertises a larger '$200 over 21 days' figure, but that is a slow drip released across three weeks, not working capital in your account up front. Our four codes are built for working capital where the model finds gaps: Kalshi FADE credits up to $500 after a $25 trade, Polymarket TGSWC turns a $20 deposit into $50, more than twice what you fund, ProphetX VAULT pays $20 on a $10 trade, and Novig VAULT credits $50 in Novig Coins after a $5 spend, each on your first qualifying step rather than a 21-day release schedule. Take the small credit or the slow drip if that is all you want; if you plan to trade college football, the codes above start you with more up front on the venues whose prices we verify daily.
Is there a promo code for FanDuel Predicts or OG.com?
No. Neither platform uses promo codes; they run standard public sign-up offers you get automatically. We have no partnership with either and do not track their markets. For college football trading, the four venues above are the ones this site prices daily, and each code (TGSWC, FADE, VAULT) carries a verified offer.
Does the OG (Crypto.com) 'up to $100' offer beat these codes?
For college football trading, no. OG (Crypto.com) has moved its pitch to an 'up to $100' credit, but 'up to' names a ceiling, not a flat payout, and it sits on a platform this site does not track or price. Our four confirmed codes are built for value that clears on your first qualifying step. Kalshi FADE credits up to $500 after a $25 trade, a ceiling five times higher; Polymarket TGSWC turns a $20 deposit into a $50 trading bonus, more than twice what you fund; ProphetX VAULT pays $20 on a $10 trade; and Novig VAULT credits $50 in Novig Coins after a $5 spend. Name the $100 only to know what to walk past; the codes above start you with confirmed amounts up front, on the venues whose college football prices we verify daily. Terms are set by each platform and can change, so confirm the current offer at each sign-up.
Is SI60's $60 the top prediction market bonus?
No. Some aggregators now push code SI60 and a flat $60 credit as 'the top prediction market bonus', superseding the earlier $35 headline. A fixed $60 is a hard cap with no upside above it, on a platform this site does not track, so the superlative does not survive a look at our four confirmed offers. Kalshi FADE credits up to $500 after a $25 trade, a ceiling well above $60; Polymarket TGSWC turns a $20 deposit into a $50 trading bonus, more than twice what you fund; Novig VAULT credits $50 in Novig Coins after a $5 spend; and ProphetX VAULT pays $20 on a $10 trade. Each of our four clears upfront on its first qualifying step and is working capital to trade with, not a one-time flat credit on a platform this site does not track, and FADE's ceiling alone runs far past $60. Name the $60 only to know what to walk past; the codes above start you with confirmed amounts up front on the venues whose college football prices we verify daily. Terms are set by each platform and can change, so confirm the current offer at each sign-up.
Do the codes change the prices I trade at?
No. The codes link your account to our sign-up offer; they do not change market prices. On every platform a contract price still maps to the market's implied probability of the outcome.
