Kalshi promo code AL25: Score $25 in bonuses for Dolphins vs. 49ers in NFL Week 2

The Miami Dolphins will visit the San Francisco 49ers on Sunday, hoping to pull off an upset. Football fans can add to the action with the nation’s biggest prediction market. New users who register with today’s Kalshi promo code AL25 will receive a $25 bonus when they trade $25 on any NFL game. Claim the bonus here, or click the banner below.

Miami will attempt to avoid a 0-2 start for the second straight season. The 49ers are coming off a surprising 20-point win over the Rams in Australia last week.

The Niners cannot afford a letdown in their home opener, especially when competing in the NFC West. Getting an early edge in the NFL’s toughest division can be pivotal.

Not many expect the Dolphins to hang with San Francisco on the road, so one market to consider is the point spread. Get ready to trade after following these instructions.

There will be an adjustment period for new Kalshi users with sports betting experience.

Kalshi is not a sportsbook and does not operate like one. Whereas betting apps rely on fixed odds, Kalshi offers implied probabilities and prices based on user trading trends.

When wagering on a mobile sportsbook, bettors compete against the house. On the best prediction markets, users trade sports results contracts with other users.

Kalshi functions like the stock market, but users trade on sports event outcomes instead of company trends. On Kalshi, customers purchase ‘Yes’ or ‘No’ contracts based on projected sports results. Contracts cost $0.01 to $0.99. Winning shares pay out $1, so the lower the price, the bigger the profit.

Kalshi is a federally regulated financial exchange licensed as a Designated Contract Market (DCM) by the Commodity Futures Trading Commission (CFTC). This association makes Kalshi available in 40-plus states nationally.

Demonstrating how Kalshi works for an NFL game: The 49ers have a 48% implied probability and a $0.49 price per contract to cover a 13.5-point spread.

If San Francisco covers the spread, winning contracts on that result pay out $1 for a $0.51 profit.

To cover the spread, the Dolphins must get better production from their quarterback and running back. In his Miami debut last week, Malik Willis did not throw a touchdown pass and was intercepted once. RB De’Von Achane was held to 66 scrimmage yards.

Miami let a mediocre Las Vegas offense easily win the time-of-possession battle and did not register any sacks. The task will be even tougher against the Niners. Brock Purdy passed for three TDs against the Rams while the defense held Los Angeles to two third-down conversions on nine attempts.

Sports fans have become familiar with Kalshi. After signing up for Kalshi, new users should shop for alternative platforms for more trading options.

The Polymarket promo code ALCOM opens the gate to a $50 bonus when you deposit $10. Polymarket is Kalshi’s top competitor and offers a wide array of sports and real-life markets. You can trade on everything from the NBA and WNBA to pickleball and handball.

Here are the verdicts on Kalshi vs.Polymarket for new users to review.

Also consider ProphetX, which is becoming better-known as a sports-only operator. Our exclusive ProphetX promo code ALCOM will unlock $75 in incentive funds after you make $50 in trades.

This is a good time to get on board with Kalshi, as pro and college football markets are drawing heavy traffic. Now is also when to start trading NBA and NHL futures.

You can also explore additional sports and games, as Kalshi offers everything from boxing and golf to sailing and darts.

Then, navigate to the non-sports topics for even more forecasting fun. Some of the most popular markets include economics, pop culture, the weather, and tech & science.

Trade on Dancing With The Stars and the next Oscar winners, and make your calls on domestic and international elections.
