In the last three months, B3 has seen a significant increase in large lot trading, with monthly volumes exceeding R$1.5 billion, and in July 2025, reaching a record of over R$3 billion. Investor confidence has grown, reflected in the increased trading of Real Estate Investment Funds (FIIs) and the implementation of new functionalities in the Midpoint Order Book, which aim to enhance privacy and efficiency in operations. The solutions are available for stocks, FIIs, BDRs, and Units, with minimum and maximum size rules set by the regulator.

In the last three months, the solutions for block trading on B3 have reached new heights, with volumes exceeding R$1.5 billion per month. In July 2025 alone, the volume traded on the BBT hit a record of over R$3 billion in a single month, highlighted by a transaction that moved R$2.3 billion, where one of the trades had a premium of 0.98 BRL (or 4.8%). Overall, as of July 11, the total volume traded has already surpassed the amount recorded for the entire year of 2024: there are now 9.2 billion in traded volume in 2025, compared to 6.5 billion in 2024. Another highlight is the increasing trading of REITs (FIIs) in blocks, available since February 2025, which has already moved over R$347 million.

The volumes of recent months have demonstrated the growing confidence and knowledge of investors in operating within these solutions, which allow for greater flexibility in trading significant volumes, protecting operations by preventing prior disclosure of offers and mitigating impacts on the central book. Below, it is possible to observe the five transactions with the highest premiums and discounts relative to the last trade of the central order book in the last three months, showcasing the flexibility provided by the BBT that has facilitated the operation of large volumes.

In addition to the BBT, the Midpoint Order Book has also stood out with the recent implementation of new features:

1. Removal of offer alerts from the news channel, allowing trading in the Midpoint to occur entirely privately, without disclosing any information about the existence of offers in the book;
    
2. Trading from the minimum size defined by the regulator, not just in multiples of that size, as was previously done. In case of partial execution, residual quantities below the minimum are automatically canceled by the platform;
    
3. Configuration of the minimum execution quantity, offering investors the option to define a minimum quantity for the execution of their orders. This configuration is especially useful for those who wish to ensure that their orders are executed under specific conditions, such as in an "all or nothing" format, where only the negotiation of the total amount is acceptable.

These improvements aim to meet the main demands of clients and evolve block trading solutions for an increasingly efficient trading experience aligned with investors' needs.

It is worth noting that solutions for block trading on B3 are available for stocks, REITs, BDRs, and Units, with minimum size rules per asset defined by the regulator (starting at R$500,000 for assets that trade less than R$5 million per day) and a maximum size of up to 1.99% of the asset's capital stock.
