Brazil’s year-end Mega da Virada lottery is poised to offer a record potential payout of approximately $200 million,and new analysis suggests how a windfall of that magnitude could perform in various investment vehicles. Simulations indicate that if fully invested in conservative fixed-income products, teh prize could generate net returns ranging from $16.7 million to $22.4 million in 2026, according to projections based on current market rates and Central Bank estimates. The prize pool has grown following the latest Mega-Sena draw, where no grand prize winner was selected.
A potential jackpot of approximately $200 million in Brazil’s Mega da Virada lottery, to be drawn on December 31st, could generate net returns between $16.7 million and $22.4 million in 2026 if fully invested in conservative fixed-income products, according to simulations based on official projections and current market rates.
The estimated prize amount was updated following the 2,954th Mega-Sena draw, which did not produce any winners of the six required numbers. Unlike regular draws, the Mega da Virada allocates a larger share of accumulated funds throughout the year, and the main prize does not roll over to subsequent draws. In the event of no six-number match, the prize money is distributed among those with the most correct numbers.
Simulation Assumptions
The simulation assumes full investment of $200 million throughout 2026, with no interim withdrawals, in low-risk products. The following assumptions were used for the calculations:
- Average Selic rate of 13.6% in 2026, calculated from market estimates for the rate at the end of 2026, according to the Central Bank’s Focus bulletin, and the prevailing expectation that rate cuts will begin with a 1 percentage point reduction at the Monetary Policy Committee (Copom) meeting in April, as indicated by Copom options traded on B3.
- Inflation (IPCA) of 4.06%, as per the median estimate from the Central Bank’s Focus bulletin.
- Post-fixed CDB at 100% of the CDI, with a minimum tax rate of 15% Income Tax, applicable to investments exceeding 720 days.
- LCI and LCA equivalent to 85% of the CDI, exempt from Income Tax, representing the net return of a CDB at 100% of the CDI.
- Short-term fixed-rate Treasury bond with a rate of 13.30% per annum, based on the shortest available term in the Treasury Direct program.
- Inflation-linked Treasury bond with a real rate of 7.82% per annum, based on the closing price of the shortest-term Treasury IPCA+ bond.
- TR of 0.17% per month for calculating savings account returns.
