Once you understand spreads, totals, and moneylines, sportsbooks offer a wide array of additional bet types. Each comes with its own pricing dynamics, strategic uses, and traps. This article covers three of the most common: live betting, futures, and alternate lines.
Live betting (in-game wagering)
Live betting is exactly what it sounds like — placing bets during a game that's already in progress. The sportsbook continuously updates the odds based on the score, time remaining, and game state. A 7-point favorite at kickoff might be a 14-point favorite by the second quarter if they jump out to an early lead.
How the pricing works. Live odds move fast. Sportsbooks use real-time models to update the lines as the game unfolds, and the vig tends to be wider on live markets than pre-game — typically 6-10% vs. 4-5% on pre-game lines. The reason is operational: the book has less time to react to news (injuries, momentum shifts) and protects itself with higher margins.
Where the edge can be. Live betting can reward bettors who watch the game and notice things faster than the sportsbook's model does. An NBA team's star sits out for a stretch with a minor injury and the model is slow to adjust — sharp live bettors can act on the information before the line catches up. The downside: this requires watching the game, having multiple sportsbooks open, and reacting quickly. It's a high-effort, high-attention strategy.
Common mistakes. Most casual live bettors lose money chasing — placing live bets to "win back" what they lost pre-game, or doubling down emotionally on a team that's losing. The vig on live bets makes this expensive. If you're going to live bet, it should be a deliberate strategy, not a reaction to results.
Futures
A futures bet is a wager on an outcome that will be determined far in advance — typically days, weeks, or months. Common futures markets:
Championship futures. Will the Lakers win the NBA title? Will the Chiefs win the Super Bowl? These are usually priced as plus-money for any team that isn't a heavy favorite.
Award futures. MVP, Rookie of the Year, Cy Young, Coach of the Year. Often available year-round.
Win-total futures. Will the Cowboys win more than 9.5 games this season? These are typically posted pre-season and remain available (with adjusted lines) throughout the year.
Specials. Will any pitcher throw a no-hitter this season? Will any quarterback throw for 5,000 yards? Sportsbooks offer dozens of these.
How futures are priced. The vig on futures markets is much higher than on game lines — often 15-30%, sometimes worse. The reason: futures are illiquid markets where the sportsbook has limited ability to balance action across many possible outcomes. They price wide margins to protect themselves.
The lock-up problem. When you bet a future, your money is tied up until the bet resolves — which could be months. A $100 Super Bowl future placed in August is $100 you can't use for other bets until February. The opportunity cost of locked-up capital is real.
When futures can make sense. Early in a season, before the market has full information, sharp bettors sometimes find prices that don't reflect a team's true probability. By late season, most futures are efficiently priced. The window of opportunity tends to be early, when there's the most uncertainty.
Hedging. As a futures bet gets closer to resolving, you can sometimes "hedge" by betting the other side at current odds. If you have a long-shot ticket on a team that's now favored to win the championship, hedging guarantees you a profit (or limits your loss) regardless of the final outcome. Whether to hedge is a math problem — sometimes it makes sense, sometimes letting the original bet ride does. We cover hedging in detail in our advanced concepts series.
Alternate lines
Alternate lines are exactly what they sound like: alternative point spreads or totals offered on the same game, at adjusted prices.
Example: an NFL game has a main spread of Chiefs -7.5 (-110). Alternate lines might include:
- Chiefs -3.5 (-220) — same team, smaller spread, lower payout because the bet is more likely to win.
- Chiefs -10.5 (+150) — same team, larger spread, higher payout because the bet is less likely to win.
- Raiders +10.5 (-180) — same game, opposite side, gives the underdog more points at a higher cost.
You can essentially "buy" or "sell" points relative to the standard line, with the price adjusting to reflect the new probability.
When alternate lines make sense. When your read on a game is stronger or weaker than the main line implies. If you think the Chiefs will dominate, buying the alternate to -10.5 at +150 might offer better expected value than taking -7.5 at -110. If you think the game will be close but the Chiefs win, -3.5 at -220 is essentially a moneyline bet with a small spread buffer.
The pricing trap. Alternate lines are typically priced to extract more vig than the main line. The sportsbook knows that bettors who use alternate lines are more sophisticated, but they also know these bettors often have strong opinions and will accept worse pricing to get the line they want. Vig on alternate lines is often 6-10% vs. 4-5% on the main line.
Practical use. A common smart play: if a team has won 12 of 13 games by 10+ points and the spread is set at -7, buying the alternate to -10 might be a better bet than -7. The probability you assign needs to be high enough to justify the lower price, but the expected value can work out.
A note on first-half, quarter, and period bets
Most U.S. sportsbooks offer markets on the first half (in football and basketball), the first quarter (basketball), or the first period (hockey). These are useful when your opinion is about how a game will start rather than how it will end.
For example: a team known for fast starts might be a better bet in the first quarter than over the full game. A heavily favored basketball team that tends to relax late in blowouts might be a better first-half bet than a full-game spread bet.
These markets often carry vig similar to game lines, but liquidity is thinner, so prices vary more across sportsbooks. Line shopping is especially valuable here.
The pattern across all these markets
Across live bets, futures, alternate lines, and period bets, the same principle applies: the more specialized the market, the wider the vig the sportsbook tends to price in. The trade-off is real — these markets offer opportunities to express opinions that game lines don't, but you pay more for the privilege.
The most profitable bettors don't avoid these markets entirely. They use them selectively, when they have a specific edge that the main lines don't let them express, and they shop the best price across multiple sportsbooks before placing any bet.
