Polymarket, Kalshi and Novig announce promo codes for Monday Night Football Week 2

Three US prediction markets have their sign-up codes live at once for the last game of NFL Week 2. Polymarket and Kalshi have confirmed their promo codes, referral codes and invite codes are active for Monday Night Football, when the Giants visit the Rams at 8:15 p.m. ET, and Novig has launched a set of promo codes across the same five Advance Local sites. On Cleveland.com, the Polymarket promo code is CLEVE, the Kalshi promo code is CLEVELAND55, and the new Novig promo code is CLEVELAND.

The three offers stack differently. The Polymarket promo code unlocks a $50 bonus on a $10 deposit—$60 total to trade. The Kalshi promo code CLEVELAND55 carries a limited-time upgraded bonus of $55 on a $25 deposit—$80 total—more than double Kalshi’s standard $25 match. The Novig promo code CLEVELAND unlocks a $25 bonus on a $10 deposit—$35 total. All three are for new US accounts only, and all three are verified and active as of Monday, September 21, 2026.

This is a network-wide update. Each of the five Advance Local newsrooms—Syracuse.com, SILive.com, OregonLive.com, MassLive.com, and Cleveland.com—has its own verified code on each platform, and all 15 are confirmed active. Here are the codes by publication:

The Polymarket promo code for Monday Night Football is CLEVE for readers on Cleveland.com. Across the Advance Local network, the five verified Polymarket promo codes are CUSE, SILIVE, OREGON, MASS, and CLEVE. Every Polymarket promo code carries the same offer for Giants vs. Rams: deposit $10, receive a $50 bonus, and start with $60 in trading funds. The same string works whether you enter it as a Polymarket promo code, a Polymarket referral code, or a Polymarket invite code—Polymarket issues one code per account across all three labels.

The Kalshi promo code for Monday Night Football is CLEVELAND55 for readers on Cleveland.com, and it is one of three codes carrying Kalshi’s limited-time $55 upgrade. Network-wide, the five verified Kalshi promo codes are CLEVELAND55, OREGONLIVE55 and SILIVE55, each unlocking a $55 bonus on a $25 deposit for $80 total, and SYRACUSE and MASSLIVE1, each on Kalshi’s standard $25 bonus on a $25 deposit for $50 total. Kalshi has not announced an end date for the $55 tier. As on Polymarket, the same string works as a Kalshi promo code, a Kalshi referral code, or a Kalshi invite code.

The newest entry on the board is Novig, a US prediction market that has launched promo codes across all five Advance Local sites for the first time. The Novig promo code for Cleveland.com readers is CLEVELAND, and every Novig code carries the same offer: deposit $10 and receive a $25 bonus, for $35 in total trading funds. Novig is smaller than Polymarket or Kalshi in market depth, but its $25-on-$10 bonus is the largest match ratio of the three platforms after Polymarket’s, and it is live for Giants vs. Rams.

Note that the Novig codes reuse familiar strings: Novig’s CLEVELAND is a different code from Kalshi’s CLEVELAND55, and Novig’s MASSLIVE is different from Kalshi’s MASSLIVE1. Each code only works on its own platform.

Here are the latest Giants vs. Rams odds on Polymarket and Kalshi heading into Monday night. On both platforms these “odds” are market-implied probabilities—prices set by real traders buying and selling contracts, not lines set by a house:

The two platforms agree on the Rams at 74%—a Giants contract pays roughly $3.70 to $3.85 per $1 if New York wins in Los Angeles—and Polymarket traders lean slightly toward the Rams covering 6.5 and toward the over on 47.5. Kalshi’s winner market on the game was the most heavily traded of the entire NFL Week 2 pre-kickoff board, with more than half a million dollars in volume before the weekend even started. Novig also lists a Giants vs. Rams winner market; its prices vary from the two larger platforms and can be checked directly in the app.

Polymarket odds and Kalshi odds reflect live trading and update in real time. All figures current as of Monday, September 21, 2026, and will move through kickoff at 8:15 p.m. ET.

All three are US prediction markets running promo code offers for Monday Night Football. Here is how they compare:

The three codes deliver value in different shapes. Polymarket’s CLEVE is the biggest match ratio—five times the deposit—and Polymarket’s peer-to-peer structure tends to produce the fastest price discovery on breaking news. Kalshi’s CLEVELAND55 delivers the largest total balance at $80 while the limited-time upgrade lasts, on a CFTC-regulated exchange with an order book. Novig’s CLEVELAND sits between them on ratio, at $25 on $10, and is the lowest-cost way to add a third prediction market account. For Giants vs. Rams, many traders open more than one account to capture each bonus and to compare Polymarket odds against Kalshi odds and Novig prices before committing funds.

Yes. All three platforms treat their referral codes and invite codes as the same strings you enter at sign-up. The Polymarket referral codes and Polymarket invite codes for Giants vs. Rams are CUSE, SILIVE, OREGON, MASS, and CLEVE. The Kalshi referral codes and Kalshi invite codes are SYRACUSE, SILIVE55, OREGONLIVE55, MASSLIVE1, and CLEVELAND55. The Novig referral codes are SYRACUSE, SILIVE, OREGON, MASSLIVE, and CLEVELAND. Whether a site calls it a referral code, an invite code, or a promo code, entering it during registration unlocks the same bonus—$60 total on Polymarket, $80 total on the upgraded Kalshi codes ($50 on SYRACUSE and MASSLIVE1), and $35 total on Novig.

Yes, for eligible users. Kalshi is a CFTC-regulated prediction market exchange, Polymarket is a prediction market open to US users, and Novig operates as a US prediction market exchange. None is a sportsbook. Instead of a house setting lines, you buy and sell contracts on event outcomes for a price between $0.01 and $0.99, and the market price reflects the probability of each outcome. That structure is why prediction markets are accessible to traders in many states where traditional online sports betting is not—though each platform maintains its own list of eligible states, and traders should confirm availability where they live before depositing. Searches for “Polymarket betting” or “Kalshi betting” are common, but all three are prediction markets—you trade contracts on event outcomes rather than playing against a sportsbook.

To recap, all 15 codes are confirmed active as of Monday, September 21, 2026. The five Polymarket promo codes—CUSE, SILIVE, OREGON, MASS, and CLEVE—each unlock $50 on a $10 deposit. The five Kalshi promo codes split into two tiers: CLEVELAND55, OREGONLIVE55 and SILIVE55 carry a limited-time $55 bonus on a $25 deposit, while SYRACUSE and MASSLIVE1 carry the standard $25 bonus on a $25 deposit. The five new Novig promo codes—SYRACUSE, SILIVE, OREGON, MASSLIVE, and CLEVELAND—each unlock $25 on a $10 deposit. On Cleveland.com, the Polymarket promo code is CLEVE, the Kalshi promo code is CLEVELAND55, and the Novig promo code is CLEVELAND.

Polymarket and Kalshi have confirmed their verified promo codes are live for Monday Night Football, Novig has launched its own alongside them, and all three offers are open now for new US accounts: $60 in trading funds on Polymarket, $80 on Kalshi’s upgraded CLEVELAND55 while the limited-time tier lasts, and $35 on Novig. Sign up with the Polymarket promo code CLEVE, the Kalshi promo code CLEVELAND55 or the Novig promo code CLEVELAND before the Giants and Rams kick off at 8:15 p.m. ET—all three are confirmed active as of September 21, and the Rams are trading at 74% on both major platforms.
