"Six years in a standard regime penal colony and USD 30,000 fine," Navalny tweeted from the courtroom in the central Russian city of Kirov as the prosecutor read out the charges.
The prosecutor had moments earlier told the court that he wanted Navalny found guilty "and arrested in the courtroom" after the verdict is read out.
Navalny was expected to issue his final statement later today. A scheduling of the verdict was also expected.
But Navalny, who plans to run for Moscow mayor later this year, and his supporters see the case as part of the Kremlin's bid to silence critics of President Vladimir Putin.
Navalny, a lawyer by training, has been leading his own defence and has repeatedly tried to prove that no one was hurt in the business deal. He has also argued that his own role in the deal was very limited.
