Just a few months ago, a top Rio official said $700 million in government aid would be needed to make up for a shortfall in balancing the local operating budget. That's no longer politically tenable.
On-going violent street protests, which began five months ago during the Confederations Cup, the warm-up for next year's World Cup, have focused on Brazil's poor schools, shabby hospitals and soaring costs. Protesters have questioned why the country is spending $15 billion on the World Cup and a similar amount on the Olympics.
The protests, at their peak, brought 1 million people to the streets across Brazil on a single day. They have grown smaller, but more violent, and show no sign of going away. Neither do charges of political corruption, which President Dilma Rousseff is sensitive to as she faces re-election just after the World Cup.
Ciuchini said $1.5 billion was the level at which government aid might not be needed to meet the Olympic budget. With "luck," he might raise even more, he said.
"Even at this level ($1.5 billion) we cannot guarantee," he said. "We are working with all the variables of the budget to make sure that we have no need for public money."
Ciuchini was upbeat, saying Brazil's sluggish economy — and distractions such as the World Cup and the threat of violence — did not harm potential sales. He pointed to Brazil's large population of 200 million and described the famous Olympic brand as one that allows "you to ring anybody in the world and they will take the call."
The countdown to the Rio Olympics reaches 1,000 days on Saturday, a big reminder the clock is ticking.
"We love to have this very high target," Ciuchini said. "This is adrenaline for a sales organization."
Income from local sponsorships should make up 20 percent of the Rio budget, which has yet to be announced. The operating budget was $2.8 billion in the original bid in 2009, but is expected to rise to at least $4 billion. Some think it could be much higher. Other major income sources are ticket sales, licensing, merchandising and a large contribution from the IOC.
The operating budget is to run the games themselves, not to build supporting infrastructure. Olympic host cities are bound by contract to pay for any cost overruns and deficits.
Rio organizers met an early sponsorship target of $500 million — including deals with Nissan, Banco Bradesco and Claro, a telecommunication company operated by Mexican billionaire Carlos Slim. Since then, things have slowed, which is worrying the top marketing official of the Switzerland-based International Olympic Committee.
"It started out very well, but they unfortunately had some economic challenges in Rio and the situation is not as it used to be," Gerhard Heiberg, head of the IOC marketing commission and an IOC member from Norway, said in an interview with the AP. "It is challenging. We still think we will get sponsors in Rio. It hasn't come up as quickly as we had hoped."
Heiberg said protests were apparently making some local sponsors skittish.
At least six deaths were connected to June's Confederations Cup protests. Jerome Valcke, the top FIFA official in charge of the World Cup, said recently the soccer tournament would have "the highest level of security you can imagine" to contain any violence.
"I know that some sponsors are waiting to see how things are going to be at the World Cup." Heiberg said. "Will it be a success? Will it be chaotic? If people feel things are going to be very good for the games, it's easier to get the sponsors. If people feel things are not going to be 100 percent, they will hold back on the Olympics. First they want to see what's going to happen with the World Cup."
