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 August 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.
- 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. Polymarket's code TGSWC turns a $20 deposit into $70 to start: your $20 plus a confirmed $50 trading bonus. A $50 headline is common now, so the sharper framing is the total, $70 in play for $20 down, on terms we re-check (last verified August 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.
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

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.
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.
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.
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.
