We're tracking perfect brackets in the 2019 NCAA tournament

Through 40 of the 63 games of the 2019 NCAA tournament, there are two perfect brackets remaining across all major online bracket games: "center road" on our Bracket Challenge Game, and "Court Stormers" on Yahoo's.

That is now the longest streak of correct bracket picks we have seen, breaking our reported record of 39 games, which happened in 2017 (we explain why we're so sure of that number below)

This is the Fourth year that is tracking tens of millions of brackets from the largest online bracket games across the country, including our Bracket Challenge Game ESPN, CBS, Yahoo, Fox, and Sports Illustrated to see when the last perfect bracket busts. Or, you know, if someone gets the first-ever verifiable perfect bracket. We're counting on the forms

The first three days had their share of upsets, but these two brackets have predicted every single one of them.

For reference, the odds of predicting which side a coin lands on 40 times in a row are 1

in 1,099,511,627,776.

We'll pick up on Sunday at 12:10 pm, ET, when Iowa faces Tennessee in the 41st game of the tournament. Both brackets have the Volunteers winning that one. Read on below for our game-by-game updates, and follow here throughout Sunday to live through the two flawless brackets:


Recap: Out or of millions or brackets entered into online games, two have remained perfect through 40 games. Before this year, 39 games were in a row. Both of the perfect brackets have the same three picks to start Sunday: Tennessee, UNC, and Duke. The first game that they disagree on is the fourth of the day: Texas Tech. Will they survive that father? We'll follow them closely to see.

  • 12:01 AM: Auburn could not miss Kansas, but one of the three remaining brackets did miss that pick. And that concludes Day 3 of the tournament. We've got two perfect brackets left.
  • 10:40 PM: Purdue knocked off the defending national champions in Villanova, which also knocked one more bracket out of the group. But the three perfect brackets that remain have our reported record of 39 games in a row. Two of those three have Auburn, one has Kansas. So we'll see at least one of those three survive the night.
  • 10:05 PM: We can safely say that we will have at least one bracket reach 40 correct picks and stay perfect until tomorrow. Purdue leads Villanova by 30 points in the second half. Three of the last four brackets have the Boilermakers. Of those, two picked Auburn in the final game of the day, and one picked Kansas.
  • 10:02 PM: 2-seed Michigan State had no problems with 10-seed Minnesota, another game all four brackets agreed on. So we've just got four perfect brackets left through 38 games. That's one away from the longest streak we've ever seen.
  • 9:26 PM: Gonzaga cruised past 9-seed Baylor, resulting in all of the perfect brackets called. Get started with four perfect brackets, now through 37 games.
  • 8:09 PM: Two brackets had picked 35 games correctly before incorrectly predicting 12-seed Murray State to beat 4-seed Florida State. That leaves us with four total perfect brackets after 36 games. Zeroing in on the record now.
  • 7:27 PM: All six of the remaining brackets picked 2-seed Michigan to beat 10-seed Florida, and all six were right. No change in the total after this one.
  • 5:08 PM: Fletcher Magee didn't make a single 3-pointer as Wofford came up just short against Kentucky. Only one of the remaining brackets had the Terriers, so we're down to six perfect brackets now.
  • 2:30 PM: The first game of the second round cut our number of perfect brackets down again, as 3-seed LSU beat 6-seed Maryland with on a last-second shot, 69-67. We're down to just seven now.
    • ESPN: 3
    • Yahoo: 2
    • BCG: 1
    • CBS: 1


Recap: We started the 2019 tournament with tens of millions of brackets . After the first day, we were down to approximately 60,000 perfect brackets. Now, through two days and 32 games, there are just 16 perfect brackets remaining across all major bracket games. On Saturday, there are eight more games, and a chance for some of those 16 brackets to the record with 40 straight correct picks. We'll keep you posted on the progress of all of them right here. The first matchup of Saturday seen 6-seed Maryland vs. 3-seed LSU at noon, ET. We'll see you then

  • 12:33 AM: 4-seed Virginia Tech hero 13-seed st. Louis at arm-length. That took out two more of our 18 brackets, so we sit at 16 total going into the second round:
    • ESPN: 10
    • Yahoo: 3
    • BCG: 2
    • CBS: 1
    • Sports Illustrated: 0
    • Fox: 0
  • 11:59 PM: 9-seed UCF had no problems with 8-seed VCU, and 11-seed Ohio State upset 6-seed Iowa State. Those games were pretty evenly split among our perfect brackets. After 31 games, we're down to just 18 perfect brackets.
    • ESPN: 10
    • Yahoo: 4
    • CBS: 2
    • BCG: 2
    • Sports Illustrated: 0
    • Fox: 0
  • 11:22 PM: UNC trailed in the first half against 16-seed Iona, but rallied in a big way. Surprisingly, one of the 66 brackets that picked the first 28 games also had Iona winning that matchup. So we're down to 65 total perfect brackets.
  • 10:05 PM: We've got a full tally – 66 perfect brackets left throughout all major online games.
    • ESPN: 48
    • Yahoo: 8
    • CBS: 6
    • BCG: 4
    • SI: 0
    • Fox: 0
  • 9:56 PM: With 28 games under our belt, we can safely say that there are under 100 perfect brackets left among the major online bracket games. At the moment, our Bracket Challenge Game has 4, ESPN has 48, Yahoo has 8, and Sports Illustrated and Fox both have 0. CBS hasn't reported or updated their leaderboard since the 24-game mark (four games ago), but we do know that they have at least a handful of perfect brackets remaining. So realistically, we're looking at somewhere between 60 and 70 perfectly brackets left. Four games left tonight
  • 9:48 PM: Liberty picked up its first-ever NCAA tournament win (the third 12-5 upset of the tournament), and we are under 100 perfect brackets left.
  • 9:14 PM: Zion Williamson made his NCAA tournament debut as Duke dominated North Dakota State. 3-seed Houston also deals with 14-seed Georgia State, 84-55. Unsurprisingly, neither of those games had much of an effect on the total number of perfect brackets.
  • 9:06 PM: Yahoo's leaderboard is up to date through 25 games, and only 36 of their 3 million brackets are still perfect.
  • 9: 00 PM: 9-seed Washington downed 8-seed Utah State 78-61, which nearly cut our total perfect brackets in half. We're down to 0.001% now.
  • 7:11 PM: ESPN is also down to just 0.002 percent through 24 games. Fox Sports has just two, and Sports Illustrated is tapped out. We probably don't know totals for CBS and Yahoo until they're under 50 each
  • 6:43 PM: 12-seed Oregon dominated 5-seed Wisconsin in the second half. The number of perfect brackets is getting real smart now. We've just got 0.002 percent at this point.
  • 6:30 PM: Buffalo held off 11-seed Arizona State, taking us down slightly to just 0.005 percent through 23 games. ESPN reported its first numbers of the day, and they're down to just 0.01 percent. We're closing in, folks
  • 5:11 PM: Virginia picked up its first win against a 16 seed since 2016 in a comeback over Gardner Webb. Only a couple of our perfect brackets didn't pick the Cavaliers. We're still at 0.008 percent through 22 games.
  • 4:58 PM: Tennessee held off 15-seed Colgate, which skimmed just to couple brackets off the top of our corpus. We're still at 0.008 percent through 21 games.
  • 4:10 PM: 13-seed UC Irvine pulled off the biggest upset of the tournament so far, taking down 4-seed Kansas State. That really did a number on the perfect brackets left. We're down to just 0.008 percent of our millions of brackets.
  • 3:40 PM: Texas Tech took care of the Northern Kentucky Norse, and the needle barely moved. [Seed] 9-seed Oklahoma throttled 8-seed Ole Miss 95-72, leaving us with 0.08 percent of brackets still perfect through 18 games.
  • 2 : 29 PM: The first game of Friday – Iowa's comeback win against Cincinnati – cut our group of perfect brackets in half, and we're down to just 0.13 percent after 17 games.
  • 12:19 PM: The first report from Yahoo is in: Only 0.2 percent or their brackets survived the first round. From what we can tell, that's about 7,000 perfect brackets on Yahoo
  • 9:40 AM: ESPN reports that just 0.25 percent brackets remain perfect in their game after the first round of action.


Recap: The first game of the 2019 NCAA tournament – 10-seed Minnesota's win over 7-seed Louisville – dropped our total number of perfect brackets from 100 percent to 31 percent. And the number kept falling. 12-seed Murray State's win over 5-seed Marquette culled the field from 12.8 percent to 4.9 percent, and 7-seed Wofford's win over 10-seed Seton Hall saw us fall below 1 percent for the first time. In the end, through the first 16 games of the tournament, we finished with just 0.26 percent of our millions of brackets that were perfect. Sports Illustrated's main bracket group had just 23 perfect brackets left, ESPN sat somewhere below 2 percent, and Yahoo and CBS were not reporting any numbers. We will get much better of the total numbers when we get a few more games under our belt today on Day 2. Stay tuned.

  • 12:12 AM: Purdue beats Old Dominion in the final game of

  • 9:42 PM: Villanova survived to Saint Mary's scare, but that wasn't too surprising to our perfect bracket corps, which sits at 2.35 percent.
  • 9:38 PM: ESPN reporting that they're down to 2.3% perfect brackets remaining through 10 games.

  • 8:44 PM: The first report from ESPN is in, and they have just 5% ]
  • 6:56 PM: Yes Morant and Murray State pulled off the annual 12-5 upset, and the perfect bracket pool shrank to just 4.9 percent through eight games. 19659011] 6:24 PM: Kansas had no problem with Northeastern, but the result did have a slight effect. Through seven games, just 12.8 percent of brackets are still perfect
  • 5:48 PM: Belmont was picked to win in 28 percent of all brackets – more than all 11 seeds other than Ohio State. The Bruins even had the ball with a chance to win at the end of the game, but came up short. That dropped our perfect bracket count to 13.5 percent.
  • 5:23 PM: Michigan State saw flashes of 2016 – when the 2-seed Spartans lost to 15-seed Middle Tennessee – against 15-seed Bradley, but managed to pull out the win. That barely moved the dial on our number of perfect brackets, which now sits at 18.6 percent.
  • 4:25 PM : Florida State took down Vermont, and took our total percentage or perfect brackets down slightly to 18.9 percent through the first four games

  • 2:50 PM: It only took the first two games of the tournament – where 10-seed Minnesota and 3-seed LSU won – to Get rid of almost three quarters of our perfect brackets. Only 25.6 percent or brackets remain perfect in our Bracket Challenge Game. We will be able to track other major games accurately until we get to a smaller number, but we will check and update this post throughout the tournament.


Before 2017, the longest perfect bracket streak we had tracked was 36, according to Yahoo! Sports. In 2014, Brad Binder went 36-for-36 to start the tournament.

In 2016, the longest anyone went was 25 games to start the tournament. This is well below the 2015 tournament's reported (and verified) best, when one person in the ESPN online bracket game picked the first 34 games correctly, according to a story by ESPN senior writer Darren Rovell. ESPN said in 2016 that its 2015 was the best start to a tournament it had on record in 18 years of its game. Yahoo! Sports reported last year that Binder's bracket was the only time it had a perfect bracket go into the second round in its 18-plus years of hosting and game. In 2017, Yahoo! reported 37 perfect first-round brackets.

So 39 is the record we made with prior to this year. With more than three decades of online and paper brackets to sift through – the current format has existed since 1985 – and with somewhere between an estimated 60 million to 100 million brackets filled out every year, the odds are decent that someone, somewhere has done better . Determining an official record is made even more difficult by the fact that online games have just begun comprehensive record keeping.

We could find no verified brackets that have been perfect in the Sweet 16 (through 48 games) at all. There was a reported instance of a bracket that was perfect through two rounds in 2010, but there was no way to verify the bracket's authenticity. It had been entered in an online game where picks could be altered between rounds according to the deadspin report at the time.

2018: Last season, no bracket lasted through even the first round, as 16- seed UMBC's historic upset of top-overall seed Virginia busted every bracket that had managed to stay perfect through the first 28 games of the tournament. Before that game there were 25 brackets that were still perfect, but all picked Virginia to beat UMBC.

2017: The 2017 tournament saw the longest perfect bracket we'd ever seen at the time, which lasted 39 games before getting an incorrect pick. That was the only one across millions of brackets we made to do it through 37 games, but when 5-seed Iowa State lost to 4-seed Purdue 80-76 in the 40th game of the tournament, its perfect run was over

2016: Three years ago the shortest run we've seen since we started tracking when the last perfect bracket last just 25 correct picks before 7-seed Wisconsin took down 10-seed Pittsburgh in the first round


So, what are the odds of a perfect bracket? Well, the popular answer is 1 in 9.2 quintillion, a number so unfathomably large that it is practically impossible to fully grasp. But that's not the case. You've got 50-50 odds to get every game correct, which is obviously not the case.

Over the past eight years, we've actually seen that Bracket Challenge Game users get about two-thirds of all picks Correct. Using that percentage, we have calculated the odds of an average user getting a perfect bracket at 1 in 120.2 billion. Not as ridiculous as 1 in 9.2 quintillion, but still pretty slim chances. If you have a unique bracket every second or every day, it would take you 3,813 years to fill out 120.2 billion brackets.

Still, this year has as good a chance as any to see the first perfect bracket picked. Stay tuned right here to see if it happens.
