Inter had stated they were willing to offload the Sweden international, who was linked to Barcelona, Real Madrid and Manchester United, but no club was willing to meet an asking price of about €70m.
Moratti says that means the 27-year-old will be staying at the San Siro. The Nerazzurri chief said: "Zlatan Ibrahimovic is absolutely off the market."
Ibrahimovic, who had intimated he wanted a new challenge, is now "happy" to remain at Inter.
The former Juventus striker said: "What happens happens. I am happy to be here, I am as pleased as the first day when I came to Inter. "
Meanwhile, Moratti added that Chelsea centre-back Ricardo Carvalho and Blues midfielder Deco were unlikely to join Inter after talks broke down over the price tag.
"These targets are more and more difficult to obtain because they are players that are very useful only at the right cost," he said when asked about the pair. "Otherwise, they risk being bad buys."
Moratti also said there will be no excuse for failure in next season's Champions League after coach Jose Mourinho played down Inter's chances, saying he was not a magician like Harry Potter or Merlin.
"We can win the Champions League, I don't want excuses," Moratti said. "Miracles aren't needed, like it wasn't a miracle winning the Italian championship last year.
"I don't think it will be difficult or miraculous to do better than last season in the Champions League."
