By utilizing the Underdog Predict promo code BROAD, new users can sign up and receive a 50% first deposit match of up to $1,000 in bonuses (or a 25% match of up to $250 in predicts-only states) for Monday Night Football tonight between the Giants and Rams. Start signing up here. This exclusive bonus also unlocks the “Keep Your Million” opportunity. Let’s elevate your NFL market strategies and maximize your trading capital ahead of this highly anticipated clash.

The Underdog platform allows us to express our views on teams, individual players, and game events by buying contracts at current market prices. We can seamlessly combine positions across all these categories into a single, unified trading portfolio. In addition to the deposit match, eligible customers gain access to the free-to-play “Keep Your Million” survival game, where you start with a virtual $1,000,000 pot in bonus funds.

Here is how I approach it to survive and cash out:

• Step 1 – Pick a question: For example, will a quarterback throw for a higher or lower percentage than a specific projected yardage mark?
• Step 2 – Split your million: Drag a slider to divide the pot between the Higher and Lower outcomes. You can go 100% on one side, split it 50/50, or anything in between. All the money has to go somewhere.
• Step 3 – Lock it in: Once you submit your position before the game starts, it’s locked. You cannot change it.
• Step 4 – Keep your winnings: When the game settles, you keep whatever you allocated to the winning side. That amount becomes your capital for the next question.
• Step 5 – Run it back: Take a position on up to 20 questions. Survive all 20, and you cash out whatever is left as Underdog bonus funds.

Use Underdog Predicts on Giants vs. Rams Tonight

While we aren’t handicapping an exacta or trifecta at the track today, the same complex principles apply to full-game prediction markets. The consensus percentages paint a clear picture of the expected outcome between the Rams and the Giants.

Team	Win Probability
Rams	\~75%
Giants	\~29%

For those looking for a nice pay day in this prediction market, a $5 trade on the favored Rams at a 75% implied win probability would yield approximately $1.64 in profit. On the flip side, trading $5 on the market underdog Giants at a 29% implied probability would net a more lucrative $12.10 in profit if they manage to pull off the upset.

When evaluating which team presents the better trade, I’m looking closely at the trends to find our edge. The Rams boast a stellar 80% straight-up win rate (16-4) as the market favorite over their last 20 games, and they are a formidable 83% at home (5-1) in their previous six contests. Furthermore, the Rams have been remarkably resilient, securing an 88% win rate (8-1) after a loss in their last nine instances, and they have won 100% of their last three head-to-head matchups against the Giants.

Conversely, the Giants enter this contest struggling to find consistency. The Giants have compiled a dismal 10% straight-up win rate (1-9) over their last 10 games. Their performance as an underdog also leaves much to be desired, sitting at just a 20% success rate (2-8) in that role over their last 10 outings. Even when coming off a victory, the Giants have struggled to maintain positive momentum, posting a 14% win rate (1-6) following a win over their last seven situations. Based on these established percentages, taking a position on the Rams appears to be the much safer addition to our trading portfolio.

Understanding Underdog Prediction Market Mechanics

For those new to the platform, Underdog operates as a true prediction market. Instead of traditional fixed options, users buy or sell contracts tied to specific, real-world outcomes.

The prices of these contracts constantly fluctuate and reflect the market-implied probability of an event occurring. If you believe an outcome is more likely to happen than the current contract price suggests, you can buy contracts to take a position. As market sentiment shifts leading up to the 08:15 PM EDT kickoff between the Giants and Rams, contract values will adjust accordingly, offering dynamic trading opportunities right up until the outcome is settled. Let’s get out there, read the market, and chase those bigger payouts together.
