Can it be that we’re already into week 9 of the NFL? The midway point of the regular season brings a full-on week featuring 15 games, from a roadshow event in Madrid to some high-stakes matchups. If you want to make your trades on this week’s games, we’ve found the two best prediction markets - Kalshi and Polymarket. We’ll tell you about the bonuses available at each and take you through some of the best trading options.
There’s no shortage of options for trading on gridiron glory this week, but we’ve focused in on two of the best prediction markets for your trades:
Of all of the games on the slate this week, Kalshi traders are really getting behind several matchups. No surprise, the Cardinals versus the Seahawks is a big draw (the Seahawks have a 78% chance of winning according to Kalshi traders). The game attracting the highest trading volume though, is the New York Giants versus the Philadelphia Eagles, which currently has a 62% lean towards the Giants.
As you’ll know if you’ve read our full Kalshi review, football trades are also available on spreads, totals and player props. So, if you fancy AJ Barner to score a touchdown, you’ll find a Yes price of $0.25.
If you want to lock in your trades for week 9 at Kalshi, now is a great time because you can grab a welcome bonus of $55 in trading funds when you register using code SPORTSPRED. To claim, you must be at least 18 and trade at least $25 in the first seven days after sign-up. Be aware that sports contracts are currently unavailable in Michigan and Nevada.
If you’re seeking a top-rated prediction exchange for your Week 9 action, then look no further than Polymarket. This highly rated prediction hub organizes your Week 9 games by trading volume so it’s easy to see which games other traders are excited about. This week, the Bengals versus the Falcons is drawing the most interest, with a current Yes price of $0.62 on the Bengals winning. The Jets game against the Chiefs comes in second, with a price of $0.81 on the Chiefs suggesting that this could be a bit of a Jet whitewash.
As well as game outcomes, you can trade on lots of other options at Polymarket. That covers spreads, totals, touchdowns, first half and second half results and props. All of these take the same Yes/No format, as outlined in our Polymarket review.
To welcome new members this week, Polymarket is extending a welcome bonus of $25 in trading funds when you deposit $10. This offer is only for new users aged 18 plus but isn’t accessible in all states. There’s no promo code needed; just make the eligible deposit and your bonus should be added to your account.
Week 9 has already started, with a Thursday night loss for the Ravens versus the Jaguars. There’s plenty more action to look forward to, though, and Kalshi and Polymarket are the perfect picks for your trades. Just follow the banners on this page to go straight to your site of choice.
