Brazil’s record lottery draw delayed by betting system failure

• Caixa Econômica Federal postponed the Mega da Virada draw from 31 December 2024 to 1 January 2025 due to unprecedented betting volumes.
• Systems experienced peaks of 120,000 transactions per second on digital channels as bettors wagered R$3.05bn on the R$1.09bn jackpot.
• The delay affected the draw itself, not prize collection, with six winners eventually splitting the historic jackpot.

Caixa Econômica Federal postponed Brazil’s Mega da Virada lottery draw after its systems struggled to process approximately 112 million bets submitted before the deadline on 31 December 2024.

The state-owned bank transferred the draw to 1 January 2025 to ensure all valid wagers were fully registered before the extraction of numbers.

Record volumes strain lottery infrastructure

The R$1.09bn (US$186m) jackpot generated unprecedented betting activity in the final hours before the 8pm deadline on 31 December.

Caixa’s digital platforms recorded peaks of 120,000 transactions per second, according to official data published by Portal Terra da Luz. Physical lottery outlets processed 4,745 bets per second during peak periods.

The total betting volume reached approximately R$3.053bn across 112 million wagers, representing an average ticket value of R$27.26. The final day alone accounted for roughly 33.5 million bets, heavily concentrated in the closing hours.

Sources familiar with the process said that Caixa decided to postpone the draw to safeguard legal certainty. Officials concluded that proceeding whilst millions of valid wagers remained unprocessed could expose the bank to legal challenges or undermine confidence in the contest.

During the official broadcast at 17:11 on 31 December, presenter Pereira Júnior informed viewers that scheduled draws had not occurred due to technical failures. Later, at 23:25, presenter Nadiara Pereira confirmed all contests would take place the following day, according to Portal Terra da Luz.

The postponement also affected other lottery products, including Quina, Lotofácil, +Milionária, Lotomania and Super Sete, which were transferred to 1 January starting at 10am.

System failures during betting period

In the days preceding the draw, Caixa’s digital systems experienced substantial instability. Users reported difficulties accessing the lottery app and website, with the Downdetector platform recording peaks in error reports on 30 and 31 December, according to TudoCelular.

Bettors encountered error messages, virtual queues lasting over an hour, and transaction failures when attempting to place wagers through digital channels. Social media users posted screenshots showing error codes including “1MPS25-99BIH40-INT” with messages stating operations could not be completed.

Caixa acknowledged the instability in a statement to TudoCelular, attributing the issues to high user flow on digital betting channels. The bank confirmed physical lottery outlets continued operating normally during the disruption.

Six winners split record jackpot

The draw proceeded on 1 January at approximately 10:55am, revealing the winning numbers: 09, 13, 21, 32, 33 and 59. Six bets matched all numbers, with each winner receiving R$181,892,881.09.

Winners included bettors from João Pessoa (PB), Ponta Porã (MS), and Franco da Rocha (SP), plus three bets placed through electronic channels. Two winners participated through group bets: one from Ponta Porã with 10 shares and another from Franco da Rocha with 18 shares.

An additional 3,921 bets matched five numbers, receiving R$11,931.42 each. Some 308,317 bettors matched four numbers, winning R$216.76 each.

The 2025 draw surpassed the previous record set by the 2024 Mega da Virada, which distributed R$635.4m amongst eight winners on 31 December 2024, according to Caixa Notícias.

Prize collection procedures remain standard

Winners must present themselves at Caixa Econômica Federal branches to claim prizes exceeding R$10,000. The bank stipulates a minimum waiting period of two business days for payment processing.

All winners must present the original winning ticket, official identification with photograph, and their CPF (Brazilian tax registry number). For physical tickets, Caixa recommends that winners complete their identification details on the reverse before visiting branches.

The standard 90-day collection period applies from the draw date. Unclaimed prizes are transferred to Brazil’s federal student financing fund (FIES) after this deadline. In 2020, one Mega da Virada winner forfeited R$162m after failing to claim within the statutory period, according to BNLData.

Infrastructure capacity under scrutiny

The 2025 Mega da Virada represented the first edition without television broadcast, with coverage exclusively through Caixa’s YouTube and Facebook channels. The transition to digital-only distribution coincided with the heaviest betting volumes in the contest’s history.

Brazil’s lottery sector contributed more than R$10bn to federal social programmes in 2023, according to industry data. For 2025, estimates suggest lottery proceeds exceeded R$1bn for allocation to education, sport, cultural development, and public security initiatives.

The technical challenges occurred as Brazil’s regulated gaming sector continues expanding following sports betting legalisation in 2018. Full regulation took effect on 1 January 2025, introducing licensed operators alongside Caixa’s lottery monopoly, according to the Brazilian government’s official announcement.

Caixa has not announced specific infrastructure improvements following the 31 December disruption. The bank confirmed regular Mega-Sena draws resumed on 6 January with contest number 2,956, returning to the standard Tuesday, Thursday and Saturday schedule.

The incident highlights operational pressures on state-controlled gaming infrastructure as betting volumes increase year-on-year. With licensed sports betting operators investing heavily in digital platforms, Caixa faces growing expectations for system reliability during peak demand periods such as the annual New Year’s Eve draw.
