Marca has reported that the Portuguese has tied down his future at the Bernabeu until 2018, increasing his salary to 17million euros (£14.8million) per year after tax and negotiating a new arrangement over the sale of his image rights in the process.
Ronaldo has two years to run on his deal at Madrid, who paid a world record £80million fee to prise him away from Manchester United in 2009, but has courted speculation over his future by revealing that he misses English football. United have subsequently been heavily linked with the player.
Ronaldo said: "I'm not going to confirm anything - I'm just going to do my job like I always do.
"My future - I don't know. At this moment I'm a player of Madrid, the future, I really don't know.
"Let's see what's going to happen - but for the moment, I'm good where I am."
He also gave little away about his thoughts on Madrid's pursuit of the Tottenham star, who is expected to break the record Ronaldo set for being the most expensive player in the world.
Madrid are believed to be ready to pay £95m for Gareth Bale but Ronaldo added: "I'm not going to speak about that because I'm not the right person to say if he deserves that money - if it's a good deal or not.
"I'm happy here - I think the players I have beside me, they are great - I'm not going to speak about other players."
Ronaldo is in Los Angeles with the Madrid squad for their tour of the USA.
Ancelotti's side have won both games they have played in the United States so far this summer, against LA Galaxy and Everton respectively in the Guinness Champions Cup.
On Wednesday they will face Chelsea in the final of the tournament, a match which pits Blues manager Jose Mourinho against his old club, a little more than two months after he and Madrid parted ways.
Mourinho gave an interview to ESPN at the weekend, in which he declared: "Madrid is politics. Madrid is not about football, Madrid is not about sport."
He also belittled his compatriot Ronaldo, by declaring that "the real Ronaldo" was the former Brazil, AC Milan, Real Madrid and Barcelona forward, with whom he worked during his period as a translator and assistant coach at Barcelona between 1996 and 1997.
Asked what he had made of his former coach's comments, Ronaldo responded: "There are some things in life that don't deserve any mention. This is one of those things and I won't comment on it for obvious reasons. I always respect my coaches and try to learn from them.
As we say in Portugal: 'I don't spit on the plate I eat on.' That's how I feel. I prefer to try and remember the positive side [to Mourinho]."
And Ronaldo denied that Madrid will be desperate to get one over their former boss when they meet Chelsea in Miami.
He declared: "We are facing Chelsea, not their coach. Athough it's like any other game, we want to win."
