At its busiest, ESPN's bracket game took in more than 766 brackets a second. By ESPN's count, 26.6 million completed brackets were in before the first round tipped off on March 19, 2026, up from 24.4 million a year earlier, a record for the fourth year running.
The rules behind the bracket screen told a different story. ESPN attached a sweepstakes to the game, the 2026 Allstate Men's Tournament Challenge Sweepstakes, and its rules put the one grand prize up for a random drawing. "Bracket results will not impact entry into the Sweepstakes," the official rules said, so a perfect bracket and a busted one carried the same single entry.
That fine print shows how far the bracket has traveled from the sheet taped to a break-room wall. The office pool, the free bracket sweepstakes, paid daily fantasy and the sweepstakes casino all get sorted by one old legal test built on prize, chance and consideration. Each also answers a question pool players care about, who holds the money, and for the newest sweepstakes sites that answer comes with the least history behind it.
The Pot Is the Players' Own Money, and State Law Asks Who Else Profits
An office pool keeps its money close. Players pay a buy-in, the pot is those buy-ins added together, and one person holds it, usually a coworker the others see every day. The format changes the scoring, not the money. A pick'em pool asks for a winner in every game, and a confidence pool has players attach a ranking, from 1 to 16, to each game.
A survivor pool, also called a knockout pool, asks for one team a week until a wrong pick ends the run, at least in its basic form. A squares pool pays whoever holds the grid square matching the last digits of the score at the end of a quarter.
That structure is what state gambling laws look at. Texas's penal code defines a lottery as prizes distributed by chance among people who paid for a chance, and its list of the names such a scheme can go by starts with the word pool. The same chapter makes betting on the result of a game an offense, a Class C misdemeanor.
Texas then gives a defense with three conditions. The gambling took place in a private place, "no person received any economic benefit other than personal winnings," and apart from skill or luck every player faced the same risks and chances. The code's definition of a private place leaves out streets, restaurants, hospitals and the common areas of office buildings, among other places.
Montana's code puts the no-cut idea in numbers, though for a narrower setting: the sports pools it limits to licensed gambling operators. The winners of any such pool must receive a 100% payout of the pool's value, with carve-outs for nonprofits, and the operator running it may not keep any portion of the money wagered or charge a fee to take part. Neither text settles whether a particular office pool is lawful, and other states draw the lines elsewhere. Both ask the same question: does anyone besides the winners get paid?
Online Contests Split the Pot Two Ways
Online contests moved the prize out of the players' hands by two routes. The first dropped the buy-in altogether. One of its legal roots is a 1954 Supreme Court case over broadcast giveaway shows such as ABC's Stop the Music, which phoned people at home and gave a prize to anyone on the line who could name a tune just played.
The Federal Communications Commission wanted such shows treated as lotteries. The Court started from the three essential elements both sides accepted, prizes, chance and consideration, and found the last one missing, because "the only effort required for participation is listening." Making the shows a crime, the Court wrote, "would be stretching the statute to the breaking point."
ESPN's 2026 sweepstakes was built the same way. Its rules opened with "NO PURCHASE, QUOTE, OR PAYMENT OF ANY KIND NECESSARY TO ENTER OR WIN," let an eligible entrant skip the bracket and enter by mailing a hand-printed 3-by-5-inch slip of paper, and allowed one entry per person. Online entrants also had to accept promotional emails from Allstate, a step the mail-in route skipped.
No entrant's money sat in that pot. ESPN Enterprises was the sponsor and Allstate the presenter, and the prize was a single $5,000 American Express gift card, with an IRS Form 1099 for the winner.
The second route kept the fee. Paid daily fantasy contests charge entrants, so they can't point to missing consideration; their case is that skill, not chance, decides the result.
A 2006 federal statute, the Unlawful Internet Gambling Enforcement Act, keeps a fantasy contest out of its definition of a bet only if it meets set conditions, and one of them turns a pool's arithmetic around: the prizes must be fixed and announced in advance, whatever the number of entrants or the fees they pay. In a pool, the fees are the prize. In daily fantasy the operator collects the money, and the prize is a promise posted before anyone plays.
A New Sweepstakes Site Can Show Its Rules on Launch Day, Not Its Payout Record
Sweepstakes casinos take both routes at once. They keep a free way to the redeemable coin, such as a mail-in request, and they sell a separate currency for play. Gold Coins, the usual name for that play currency, have no cash value. Sweeps Coins are the ones a player can cash in for prizes, under conditions each operator sets, and they also arrive bundled with Gold Coin purchases. The sites are for adults, with the minimum age set in each operator's terms.
That leaves the money with the operator from both ends. It takes the payments for Gold Coins, and its own rules decide when a Sweeps Coin balance can become a prize. A pool player would ask one more thing of whoever holds the money: have they paid out before?
A commissioner answers with last season. A site that opened in the summer of 2026 has a few months of history at best, unless its parent company already runs other brands. One launch log, PlayUSA's running list of new sweepstakes casinos, records when each site went live, holds pre-launch brands apart from sites already open to players and sets out the checks it applies to a newcomer, from ownership details and the sweepstakes rules to state restrictions and redemption terms.
In the copy read on October 5, 66 entries carried a 2026 launch month, the most recent dated August, and five more were still marked TBD. The guide says plainly that new sites haven't had as much time to prove their redemption process. A brand from an operator with other sites can be read partly through that operator's history, a point the same guide makes about sister sites. For a brand-new company, the rules are public on launch day, while a payout record takes time to build.
The Labels Came After the Launches
States have sorted the two online formats that take money after those formats reached the public, not before. On October 15, 2015, Nevada's Gaming Control Board concluded that daily fantasy "constitutes gambling under Nevada law," said offering it required a license to operate a sports pool and told unlicensed operators to cease and desist.
For sweepstakes casinos, that sorting is still under way. LD 2007, which Maine's governor signed on April 6, 2026, defines consideration two ways. The direct kind is a coin bought, or received as a bonus, and then used to play; the indirect kind is a coin given free, or with a purchase, that can be exchanged for a prize. The law prohibits casino-style online games that take either kind for play.
Those two terms have a history. In 1954 the FCC argued that "it is of no consequence whether such consideration be direct or indirect," and lost under a federal statute, as the Court's opinion records. Maine has now written the distinction into a law of its own.
The Pool Moved Online and Left the Money With the Commissioner
The pool made the trip online too and kept its oldest arrangement. OfficePoolStop's own history says its founder, Fred Williams, and fellow engineers invented a Bookie pool, also called a Play Money pool, in the early 1990s. The site's version gives each player $100 in play money a week to put on NFL games against the spread. Its first full-featured website launched in 2012, and in early October 2026 its homepage was announcing a mobile app.
Under its current rules, the site stays out of the money. Managers can track fees, add online payment support and enter prizes on a Player Accounts page, but OfficePoolStop's terms of use say it doesn't collect entry fees or distribute prizes. The same terms say the site doesn't support or permit gambling, cap entry fees at $150 a player, require leagues to run on a non-profit basis and bar managers from profiting. Those last two lines echo the no-cut condition in the Texas defense.
Set side by side, the four formats leave the money with three different holders.
| Format | Who pays to enter | Who holds the money | Which test applies |
| Office pool with a buy-in | Each player, through the buy-in | The commissioner, a person the players know | Turns on state law, such as Texas's private-place defense |
| Free bracket sweepstakes, such as ESPN's in 2026 | Nobody, since online and mail entries are free | The sponsor, ESPN Enterprises | Consideration removed, with the winner drawn at random |
| Paid daily fantasy | Each entrant, through the entry fee | The operator, which posts prizes in advance | Skill over chance, though Nevada required a sports pool license in 2015 |
| Sweepstakes casino, the model Maine's 2026 law bars | Nobody has to, though Gold Coins are sold for play | The operator, which sells the play coin and approves redemptions | Free entry to the prize coin, contested state by state |
The last column has shifted before and may shift again. The third is the one a player can check before paying anything: who will be holding the money when it's time to pay out, and what that holder has already shown.
