Two Week 1 results have already moved prediction markets more than anything else this season, and Week 2 is shaping up to move them further. The Los Angeles Rams opened as the clear Super Bowl favorite on every platform, but a 27-7 defeat to the 49ers, the largest Week 1 loss by a preseason favorite in 50 years of odds data, has already reshaped contract pricing across the board.
Seattle's result cuts the other way. The Seahawks beat the Patriots 13-10 in the Super Bowl LX rematch, but quarterback Sam Darnold's first-quarter hip injury is the detail worth trading on. That kind of news will shift a team's title price heading into Week 2.
This guide covers the current welcome offers from Kalshi, Polymarket, ProphetX, Novig and OG.com in full. It also breaks down how prediction markets work, a live pricing comparison on the Rams' Super Bowl contract and where each platform currently stands with regulators heading into the season.
What Is a Prediction Market? How Is It Different From a Sportsbook?
Prediction markets are a newer, different category from a standard sports betting site. Instead of placing a bet against the house at fixed odds, you buy or sell a contract priced between $0.01 and $0.99, representing the market's current implied probability that an event happens. That contract settles at $1 if the outcome occurs, or $0 if it doesn't.
A contract trading at $0.60 reflects roughly a 60% chance the event happens. That price moves in real time as new information comes in. This can be an injury report, a trade or a general shift in public sentiment, the same way a stock price moves on news.

Two other differences set these platforms apart. First, they're regulated federally by the Commodity Futures Trading Commission (CFTC) rather than licensed state-by-state like traditional sportsbooks and casinos. Second, trading is peer-to-peer: you're buying and selling contracts against other users rather than against the operator. The platform typically earns a small fee or spread on the trade rather than baking a house edge into the price itself.
That federal framework is why several of these platforms can legally operate in states where regular sports betting itself remains illegal. That’s because they're classified as derivatives exchanges rather than gambling operators.

NFL Prediction Market Contract Pricing: Why It Pays to Compare
Shopping around matters on prediction markets just as much as it does on sportsbook NFL odds. The Rams' Super Bowl LXI contract is a clear example of that right now. Kalshi's own tracking shows the Rams opened the season at 17% to win it all, and that price has already dropped to somewhere between 13% and 14% following the Week 1 loss, sliding further once Myles Garrett's knee surgery was confirmed.
San Francisco 49ers moved in the opposite direction, climbing from roughly 5% to 8% on the back of a genuinely complete performance on both sides of the ball.
That shift is exactly the kind of move that rewards checking more than one platform before buying into a position, rather than assuming Monday's price still holds by Wednesday.
Polymarket pulled its market on whether Patrick Mahomes would play in Week 1 after his snap counts made the outcome a non-issue, which is a reminder that prediction markets don't just reprice on news. They sometimes cancel a market outright once its underlying question is settled.
Kalshi's per-contract fee is deducted automatically when a position is opened, so the price displayed on screen already reflects the cost of entering, not just the raw contract price.
Best NFL Prediction Markets
Kalshi
Kalshi carries the deepest liquidity of any prediction market covered here, and its NFL section reflects that scale. Beyond game-by-game contracts, Kalshi has a full futures board covering the Super Bowl, conference champions and division races, with enough trading volume behind the major markets to keep pricing tight even on high-profile games like the Rams' season opener.
That depth also tends to mean faster order fills, since there's usually another trader on the other side of your position. New users can trade $25 and get $25 using Kalshi promo code BOOKIES, and the offer is open to traders 18 and older.
Polymarket
Polymarket's strength is depth paired with speed. Its markets tend to move fast when news breaks, since pricing comes from crowd trading rather than a set line from the operator. That makes it a useful read on how traders are reacting to storylines in near real time, not just on game outcomes themselves.
New users can deposit $10 and receive a $50 trading bonus with Polymarket promo code BOOKIES. The offer is restricted to those 18 and older, and it's worth noting Polymarket's US-facing product runs through a separate, CFTC-regulated entity from its main international site.
Used 17 Times Today Polymarket Prediction Welcome Offer Ts and Cs: 18+ Only. Restrictions and eligibility requirements apply. Not available in all jurisdictions. Trading is risky. 100% loss can occur. See polymarket.com/tos for more information. The Polymarket US App serves as an independent software provider and affiliate of Polymarket US and Polymarket Clearing, the CFTC-regulated exchange and clearing organization.
ProphetX
ProphetX is built for traders chasing the sharpest available price rather than a fixed line. As a peer-to-peer exchange, it lets you post your own price and wait for a match rather than accepting whatever a sportsbook offers, giving active traders more control over the exact number they're willing to trade at.
Profitable parlays carry a 0% fee, which stands out against the vig baked into most traditional sportsbook parlay pricing. New users can make $50 in trades and get $75 back using the ProphetX promo code BOOKIES, and it is open to traders 18 and older.

Novig
Novig relaunched in August 2026 as a CFTC-regulated exchange, moving away from its older sweepstakes-style setup. The platform runs on a real no-vig model: you trade against other users rather than the house.
Novig earns from a small spread rather than a built-in edge on every contract. New users can deposit $10 or more and receive $25 in Trade Credits using Novig promo code BOOKIES. Novig's age requirement sits at 21 and older, which is older than every other platform on this page, so it's worth checking before you sign up.

OG.com
OG.com is the smallest featured entry here, built on the backbone of Nadex, one of the original CFTC-regulated exchanges, now rebranded under Crypto.com's ownership. That heritage makes it a natural fit for traders already comfortable in the Crypto.com ecosystem. New users can trade $10 and get $10 back with no code required, open to traders 18 and older.
This offer is smaller than the other four platforms here, and state access is more restricted too. Arizona and New York residents can't sign up at all. Traders in Illinois, Maryland, Massachusetts, Michigan, Nevada, New Jersey and Ohio can access the platform, but they're blocked from sports contracts and limited to non-sports markets like politics instead.
How Prediction Market Fees Actually Work
Each platform charges differently. Kalshi's per-contract fee scales with how close a contract sits to $0.50, so a coin-flip market costs more to trade than one priced near the extremes. Polymarket's taker fee follows a similar shape, while ProphetX waives fees entirely on parlays that finish in profit. Novig markets itself as commission-only with no house vig baked into the displayed price, which is a different structure from a per-contract fee charged on entry. Checking how a platform's fee is applied, on entry, on exit or only on a win is always a smart thing to do.
OG.com's exchange fee applies at the point of opening a position rather than on exit, so the displayed price already reflects the full cost of entering that particular contract.
Where Are NFL Prediction Markets Legal?
State availability for prediction markets works nothing like the standard sportsbook or even DFS sites map, and it's in flux right now rather than settled. Unlike traditional sports betting, where most licensed states share broadly similar rules, each of these platforms is fighting its own separate legal battles state-by-state, and several rulings have landed within just the past few weeks.
Kalshi currently faces active restrictions or contested access in multiple states, including Nevada, Michigan and Washington, with further cases ongoing elsewhere, centered on whether its sports event contracts count as regulated derivatives or as gambling under state law. Courts in different states have reached different conclusions on that exact question, which is part of why the list keeps shifting rather than settling into something stable.
Polymarket and ProphetX generally claim close to nationwide coverage, though Polymarket's setup is worth understanding on its own: American traders use a separate, CFTC-regulated entity called Polymarket US rather than the main international site, which blocks US access outright. Novig relaunched in August 2026 covering 47 states, sitting out Arizona, Michigan and Nevada as of this writing, with Washington access contested separately in court.
OG.com runs the tightest map of the five. It's fully blocked in Arizona and New York, and it restricts sports contracts, while still allowing non-sports markets, in Illinois, Maryland, Massachusetts, Michigan, Nevada, New Jersey and Ohio. Given how quickly this landscape is shifting, treat every figure here as a snapshot taken at the time of writing rather than a permanent list, and check each platform's own regulatory page before signing up.
