Auburn made it to the Final Four in Indianapolis. Except it’s the NIT semifinals, not the NCAA Tournament semis that will start Saturday just down the road.

Tonight, the favored Tigers take on Illinois State in the second semifinal game. Tip-off is scheduled for 9:30 pm, ET, following the Tulsa-New Mexico game at 7 pm. Both games are at historic Hinkle Fieldhouse, about a 10-minute drive from Lucas Oil Stadium, site of this weekend’s Final Four.

Auburn, of course, started its NIT journey firmly believing it belonged in the NCAA Tournament. Illinois State (23-12, 12-8 MVC) gladly embraces the underdog role after an impressive campaign that earned a third-place finish in the Missouri Valley Conference.

Our detailed analysis breaks down the semifinal and offers the best bets for Auburn vs. Illinois State.

Illinois State vs Auburn Odds

• Moneyline: Auburn -352 / Illinois State +277
• Spread: Auburn -7.5 (-115) / Illinois State +7.5 (-105)
• Total: Over 149.5 (-108) / Under 149.5 (-112)

Odds as of April 2, 2026, at 1:27 PM EST from consensus odds.

The betting market has firmly established Auburn as a significant favorite, laying 7.5 points on the spread and carrying a steep -352 price tag on the moneyline. Meanwhile, the consensus total is holding steady at 149.5, though the juice slightly favors a lower-scoring outcome with the Under priced at -112.

Looking past the sportsbook vig, we can calculate the true, implied probabilities of either team advancing. When normalizing the moneyline odds, the market implies a 74.59% true probability for an Auburn victory. Conversely, Illinois State is given a 25.41% chance of pulling off the outright upset in Indianapolis.

For bettors looking to translate those odds into potential payouts, a standard $10 wager illustrates the dramatic gap in straight-up value. Backing the heavily favored SEC squad on the moneyline would yield a total payout of just $12.84 (a meager $2.84 profit). Placing that same $10 bet on the underdog at +277 would result in a handsome total payout of $37.70 ($27.70 in pure profit) if the post-season surprise comes to fruition.

Prediction site Kalshi also offers moneyline contracts. At Kalshi, each Auburn to win contract is trading for $0.75 per, which equates to -300 odds. That presents more value than the consensus odds at a sportsbook. That same $10 investment at Kalshi would produce a $3 profit if the Tigers win.

Auburn vs Illinois State Predictions & Best Bets

The Pick: Illinois State +8.0 (-110 Caesars)

It’s tempting to go all-in on Auburn’s SEC background and expect a route, but the Tigers didn’t pounded any of their three previous NIT opponents. We’re expecting Auburn to win again, in another relatively close game that falls short of the number.

When handicapping this game, finding betting value often comes down to tracking market movement, identifying situational trends, and making sure to shop around to find the best available odds.

The consensus betting market opened this contest with Auburn as a 6.5-point favorite. However, early action has steadily pushed that number, moving the line across the critical key number of seven to settle at -7.5. (Again, shop around, because Caesars has it at 8.0.) While the moneyline price has ballooned from an opening mark of -275 to a steep -352 — putting it well past the threshold for a playable straight bet — the widened spread creates an excellent opportunity to back the underdog.

Getting the hook on a 8-point spread in a post-season, neutral-site game is a mathematical advantage. Auburn arrives with a glaring situational trend: a 2-8 straight-up record (20% win rate) when forced to play on the road. Taking a team that wins just 20% of its road games to cover a 8.0-point number is a negative expected value (-EV) proposition. Conversely, Illinois State enters having won 70% of its last 10 games (7-3). With the market adjusting to heavily back the SEC brand, shopping around for the best available odds to take the points at -105 offers the most logical value.

The Pick: Under 149.5 (-110 at FanDuel)

The Under 149.5 at -110 is the sharpest totals play on the board. Neutral-site tournament games inherently force teams to rely on half-court execution rather than transition scoring, making it difficult to reach implied team totals of 78.5 and 70.5.

Public Betting Trends and Splits

Analyzing the college basketball public betting splits is critical. The data reveals clear preferences, setting up intriguing contrarian opportunities.

The Moneyline Market: Bettors are overwhelmingly backing the favorite to win outright.

• Auburn: 98.31% of tickets | 97.39% of the money
• Illinois State: 1.69% of tickets | 2.61% of the money

Both the ticket volume and the financial stake are heavily consolidated. There is no sharp divergence here; the betting public and larger bankrolls are fully aligned, leaving virtually zero support for a straight-up upset.

The Spread: While the moneyline is entirely lopsided, the spread market offers a much more balanced picture.

• Auburn: 56.41% of tickets | 62.5% of the money
• Illinois State: 43.59% of tickets | 37.5% of the money

Auburn commands the majority of both the bet percentage and the all-important handle. Because neither side holds a sharp-versus-public divide, the data confirms that our official spread prediction—Illinois State +7.5—is a contrarian play. By taking the points, we are actively fading the 62.5% of the money backing the favorite to cover.

The Total: The most dramatic contrast between the betting public and our official prediction lies in the totals market.

• OVER: 92.9% of tickets | 83.32% of the money
• UNDER: 7.1% of tickets | 16.68% of the money

The public loves points, funneling an overwhelming 83.32% of the financial stake toward a high-scoring affair. Taking the Under 149.5 positions us squarely against the grain of the betting masses, banking on half-court execution to suppress the final score.

Auburn vs Illinois State Tale of Tape

Furthermore, the data strongly validates taking the underdog on the spread. Despite playing in a top-heavy conference, Auburn’s .556 win percentage pales in comparison to Illinois State’s .657 mark. More importanty, Auburn has been dreadful when forced to pack its bags, posting an alarming 2-8 road record this season. Illinois State holds a superior average point differential (+7.0 compared to +3.7) and has been the hotter team down the stretch. Superior defensive metrics and a proven ability to hang tough in unfamiliar buildings make the underdog a highly live play against the number.
