The biggest sports betting trend in 2026 is the rise of sports prediction markets, which now let bettors in nearly every state trade on games, alongside record sportsbook revenue, new states, higher taxes and a crackdown on bets that are easy to rig. Here are the eight trends shaping how Americans bet on sports in 2026, each checked against current sources as of October 2026.

1. Sports prediction markets go mainstream
The trend that defined 2026 is the spread of sports event contracts. Prediction markets regulated by the Commodity Futures Trading Commission, led by Kalshi, let users buy and sell contracts on game outcomes in states where sportsbooks are not legal, including California and Texas. Sports drove more than 90% of Kalshi's activity in 2025.
The sportsbooks followed. DraftKings launched DraftKings Predictions on December 19, 2025, in 38 states, and FanDuel launched FanDuel Predicts with CME Group on December 22, 2025. FanDuel offers sports contracts only in states where online sports betting is not yet legal, and says it will stop offering them in any state that legalizes.
The legal question is unsettled. The Third Circuit has blocked New Jersey from applying its gambling laws to Kalshi, while the Ninth Circuit sided with Nevada and, on September 25, 2026, the Sixth Circuit ruled that Ohio and Tennessee can regulate event contracts under their gambling laws. That split makes a Supreme Court case likely. New York has also sued Polymarket. For a plain explanation of how these markets work, see what prediction markets are and prediction markets vs sportsbooks.

2. Record sportsbook revenue, and the books keep more
Legal US sportsbooks set a record in 2025, with $16.96 billion in revenue on $166.94 billion in handle, according to American Gaming Association figures reported by ESPN. Handle grew 11%, but revenue grew about twice as fast, which means books kept a larger share of every dollar bet: roughly 10.2% in 2025 by our math from those figures.
For bettors, a rising hold is a cost. It comes mostly from the mix of bets, with more money in parlays and props that carry bigger margins. That is why line shopping and paying attention to the vig matter more in 2026 than they did a few years ago.
3. Parlays and same game parlays drive growth
Parlays are the growth engine on both sides of the industry. Sportsbooks push same game parlays because they combine several priced outcomes and multiply the margin on each leg, and prediction markets added combo contracts that work the same way and quickly became a large share of their football trading. The appeal is the big payout; the cost is the compounding house edge. If you play them, price each leg first with a parlay calculator and read our same game parlay guide.
4. New legal states, slowly
Legal online sports betting is still expanding, but in small steps. Missouri launched on December 1, 2025, after voters approved Amendment 2 in 2024. On April 9, 2026, Wisconsin Governor Tony Evers signed Assembly Bill 601, which legalizes online sports betting run by the state's 11 tribes, though mobile betting cannot start until the state and tribes sign updated gaming compacts. Large states such as California and Texas still have no legal sportsbooks, which is exactly where prediction markets have grown fastest.

5. Higher taxes on sportsbooks and on winners
States keep raising sports betting taxes. Maryland raised its mobile rate from 15% to 20% in July 2025, Louisiana raised its rate from 15% to 21.5%, and Illinois added a per-bet fee of 25 cents on each of a sportsbook's first 20 million bets in a year and 50 cents after that. Higher costs for the books tend to show up as fewer promotions and worse prices for bettors.
Bettors face a federal change too. Starting with the 2026 tax year, the One Big Beautiful Bill Act caps the deduction for gambling losses at 90% of losses, so a bettor who wins $50,000 and loses $50,000 can owe tax on $5,000 of income they never made. Efforts to repeal the cap had not passed as of this update. Keep complete records: a bet tracking app makes tax time far easier.
6. The integrity crackdown on player and pitch bets
Betting scandals reshaped what you can bet on. In October 2025, federal prosecutors charged Miami Heat guard Terry Rozier and Portland Trail Blazers coach Chauncey Billups in separate gambling cases, and both pleaded not guilty. In November 2025, Cleveland Guardians pitchers Emmanuel Clase and Luis Ortiz were indicted over an alleged scheme to rig individual pitches.
The response came fast. MLB and its sportsbook partners capped bets on individual pitches at $200 and barred them from parlays, and more states pulled college player props, with Ohio, Maryland, Vermont and Louisiana among those that removed them. Expect fewer micro markets tied to a single player's single action, and more scrutiny of unusual betting patterns.
7. Peer-to-peer and social betting grow up
A sportsbook profits when you lose, and more bettors are noticing. One of the clearest latest trends in online sports betting is the shift toward models where you bet against other people instead of a house: betting exchanges, peer-to-peer marketplaces and prediction markets. Prices are set by the market rather than padded on both sides, and the platform earns from activity rather than from your losses.
BettorEdge is the peer-to-peer version built for sports fans. More than 35,000 bettors use it to bet against each other at fairer prices, post their own numbers, and compete with friends through pick'ems, squares, leaderboards and group competitions.

8. AI, models and better tools for bettors
Data tools that used to be for professionals are now cheap or free: odds screens, projection models, bet trackers and AI assistants that summarize injury news and matchups. That helps bettors work faster, but it also means the easy edges disappear quickly, because the sportsbooks and the sharpest bettors use the same tools. The practical result is that price matters more than ever: the same analysis is worth more at a better number.

What these sports betting trends mean for you
- Shop every bet. With books keeping more of each dollar, the gap between the best price and the worst is your margin.
- Treat parlays as entertainment. They are where the house edge is largest.
- Track everything. Between the new tax rules and the need to know your real ROI, a complete record is no longer optional.
- Know which product you are using. A sportsbook, a prediction market and a peer-to-peer marketplace are regulated differently and price bets differently.
Sports betting trends 2026 FAQ
What is the biggest sports betting trend in 2026?
The biggest sports betting trend in 2026 is the growth of sports prediction markets, which let people trade contracts on game outcomes even in states without legal sportsbooks. Kalshi leads the category, and DraftKings and FanDuel launched their own prediction products in December 2025. Federal appeals courts have split on whether states can regulate them, which points toward a Supreme Court case.
How big is the US sports betting market in 2026?
The US sports betting market produced a record $16.96 billion in sportsbook revenue in 2025 on $166.94 billion in handle, according to American Gaming Association figures reported by ESPN. Handle grew 11% while revenue grew about twice as fast, because more money went into higher-margin bets like parlays. Those figures do not include prediction markets, which are regulated federally.
Which states legalized sports betting most recently?
Missouri was the most recent state to launch legal sports betting, going live on December 1, 2025. Wisconsin legalized online sports betting through its tribes when Governor Tony Evers signed Assembly Bill 601 on April 9, 2026, but mobile betting there requires updated tribal gaming compacts before it can start. California and Texas still have no legal sportsbooks.
How are sports betting taxes changing in 2026?
Starting with the 2026 tax year, federal law caps the deduction for gambling losses at 90% of losses, so break-even bettors can owe tax on income they did not keep. Several states have also raised taxes on sportsbooks, including Maryland to 20%, Louisiana to 21.5% and Illinois with a per-bet fee. Higher operator taxes tend to mean fewer promotions for bettors.
Is peer-to-peer sports betting growing?
Yes, peer-to-peer sports betting is growing as bettors look for prices without a house margin built in. Exchanges, peer-to-peer marketplaces and prediction markets all match bettors with each other instead of taking the other side. BettorEdge, a peer-to-peer marketplace with more than 35,000 bettors, is available in 45+ states.
