Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.
The board of Helbor, a São Paulo property developer, on Tuesday 20 October 2026 recommended that shareholders accept a share-swap offer from HBR Realty to take the company private and leave the B3 stock exchange. The offer values each Helbor share at R$2.52 (about US$0.50), and the auction is set for Wednesday 28 October at 2 p.m. ET.
Both companies sit under the same controlling family, which makes the deal a test of how minority investors in Brazil’s economy are treated when a controller buys out its own listed company. Helbor trades on B3 under the ticker HBOR3, and we found no US listing for it.
What the Board Decided
Helbor’s board of directors issued a favourable opinion on the offer on 20 October and told shareholders to accept it. The company published the opinion in a filing, and Brazilian media reported it late that evening.
The offer is a share swap, so no cash changes hands. Each Helbor share is exchanged for 0.81553398 ordinary shares of HBR Realty, which values Helbor at R$2.52 per share (about US$0.50, converted at R$5.02 per dollar, the RT rate on 20 October).
Who Is Buying and Why
HBR Realty owns income-producing property such as shopping malls and corporate offices. Helbor is a developer that builds and sells housing.
HBR said in July that the combination would create a land bank, the plots held for future projects, concentrated more than 80% in São Paulo city, with less exposure to the swings of the building cycle. HBR’s own board approved the offer on 3 July, and the CVM cleared the registration of the offer on 5 October.

How the Auction Works
The auction takes place on Wednesday 28 October 2026 at 3 p.m. in Brasília, which is 2 p.m. ET, on B3’s electronic trading system. Shareholders would take part through their brokers.
The deal settles only if HBR ends up controlling Helbor and holders of more than two-thirds of the shares eligible to take part accept the swap. If it succeeds, Helbor’s registration with the CVM is cancelled and the company leaves B3’s Novo Mercado, the exchange’s top governance tier.
The valuation report was prepared by the consultancy Apsis under CVM rules, BTG Pactual acts as the intermediary and guarantees the financial settlement, and Bradesco BBI issued an independent opinion on the exchange ratio.
What It Means for US Readers
Helbor trades on B3 as HBOR3 and we found no US listing, so most dollar investors will watch this deal rather than trade it. It matters as a signal, because Brazilian companies have been leaving the Brazil stock market, a trend we explain in our guide to why companies keep leaving B3.
Holders of HBR shares received through the swap would own a larger company that adds Helbor’s housing business to HBR’s rental property. Investors who want the background can read our Helbor company profile and our earlier report on the HBR takeover vote.
What Is Not Known
It is not yet known how many minority shareholders will accept, which decides whether the two-thirds test is met. It is also unknown how HBR shares will trade once the swap is complete.
The result of the auction will follow on 28 October, and we will report it.
What Comes Next
- Wednesday 28 October, 2 p.m. ET: the auction on B3’s electronic system.
- After the auction: whether the two-thirds threshold was met.
