How the Kalshi NFL Promo Code LABS Works

The offer is tied to trading volume rather than whether a first position wins or loses. Eligible new users register with LABS, fund the account and complete at least $25 in qualifying trades to unlock the $25 promotional credit.

Kalshi contracts generally trade between 1¢ and 99¢. A contract priced at 45¢ represents roughly a 45% market implied probability and settles at $1 if the selected outcome occurs.

That structure separates Kalshi from a conventional sportsbook, where the operator posts fixed odds. On Kalshi, prices move as participants buy and sell positions on the best prediction markets.

Broncos vs. Chiefs Kalshi Odds

Kansas City enters Monday night as the favorite, but the prediction market is treating Broncos Chiefs as a competitive matchup. This is the perfect setup for the Kalshi NFL promo code LABS, and your bonus from one of the best prediction market promos.

Chiefs winner contracts have generally traded in the mid 50 cent range, while Denver has been available in the mid 40s.

Outcome	Kalshi Price	$100 Buy Pays
Chiefs to Win	About 56¢	About $179
Broncos to Win	About 44¢	About $227

A Chiefs contract around 56¢ implies approximately a 56% chance of Kansas City winning. Denver offers the larger potential return at roughly 44¢. These prices can continue moving before kickoff, so confirm the live Kalshi board before entering a position.

Broncos vs. Chiefs Prediction

Denver’s biggest advantage comes from its pass rush against a Kansas City offensive line dealing with an important absence.

Left tackle Josh Simmons is out, putting undrafted rookie Kahlil Benson in line for a difficult first NFL start while protecting Mahomes’ blind side. Denver has enough talent up front to create pressure without constantly sending extra rushers, which could force Kansas City into a quicker passing game.

The Chiefs still deserve to be favored at Arrowhead. Mahomes gives Kansas City the quarterback advantage, and playing at home makes the Chiefs difficult to fade outright.

Denver, however, has enough defensively to keep the game close and give Bo Nix opportunities late.

At that price, Denver offers enough upside to justify taking them as an underdog. The Broncos do not need to control the entire game. They need their defensive front to disrupt Mahomes enough to keep this within one possession and create a late opportunity to win.
