Yes and no. Hamlet claims that he is faking his madness, but there are times where the reader can't truly tell whether hamlet is mad or not. It is up to interpretation. Whether his madness was truly fake or not is up to the kind of interpretation the reader/actor puts into it.
Because Hamlet is behaving that way. Everyone sees him wandering around the castle like a looney. But most importantly, he broke into Ophelia's private room half-naked and behaved in a very weird way toward her. She thought it was creepy, apparently.
If you mean insane. No, when his father ( a ghost) told him that is uncle murdered him by putting the poison in his ear while he slept Hamlet decided that he had to trap his uncle and his mother. He did that by acting mad and making everyone think he didn't know what he was doing so they wouldn't kill him. If you remember his uncle did send men to kill him. It isn't until he stages the play about the murder that the uncle realizes Hamlet knows the truth and arranges for his death when he fights the duel and gets stabbed with the poisoned tip of the sword.
By badgering Polonius with half-babbling that could be wise insults, by violently confronting his mother and Ophelia, by seeing a ghost, by killing people...
Hamlet vows to affect madness in order to deceive others by putting "an antic disposition on" (1.5.172). This "mask" would enable Hamlet to observe the interactions in the castle.
Gertrude thinks Hamlet is mad because Hamlet bursts into Ophelia's personal dressing closet in less than the acceptable clothing for the Elizabethan time period and acts mad .
his love for Ophelia.
Claudius does not ask Hamlet what he has done with Polonius, although Rosencrantz and Guildenstern do. He asks Hamlet where Polonius is. His lines are "Now, Hamlet, where's Polonius?" and "Where is Polonius?". Hamlet answers, first that Polonius is at supper (not where he eats but where he is eaten) and second that Polonius is in heaven (where Claudius cannot go to find him). Then he adds, "But if indeed you find him not within this month you shall nose him as you go up the stairs into the lobby."
Polonius thinks that Hamlet has been driven mad because Polonius told Ophelia to reject all letters and gifts from Hamlet. He is, in Polonius's view, suffering from unrequited love. It is typical of someone as full of himself as Polonius is to imagine that whatever is going on is all due to something he himself did.
Polonius is sure that Hamlet has gone mad with love for Ophelia. See these lines by Polonius in Act 2 scene 1: ~Polonius: Come, go with me! I will go seek the King;This is the very ecstasy of love,...Ophelia: ... I did repel his letters, and denied His access to me.Polonius: That hath made him mad;~ So Polonius thinks Hamlet is suffering from the "ecstasy of love" for Ophelia, which has driven him mad.
Ophelia, who drowns (maybe a suicide as she is mad and so falls into the water). She is mad out of grief for her father polonius, who Hamlet killed accidentally.

Polonius is interested in seeing whether spying on Hamlet's conversation with Gertrude will justify his theory that Hamlet is mad for love. (see the end of Act 3 Scene 1)
Part of the answer has to depend on when you think Hamlet figures out that Polonius is listening in. If you think Hamlet knew from the start, then he may be saying "No, I never gave thee ought." to make Polonius think that their relationship was less serious than it really was. Or possibly the return of the love-tokens tips him off, and his lines "Are you honest?" and "Are you fair?" are really intended for Polonius. Perhaps "Get thee to a nunnery" is intended for Polonius (perhaps to make him think Hamlet as angry with Ophelia to try to save her from being implicated in Hamlet's problems), and "We are arrant knaves all; believe none of us" is to Ophelia so she knows he's not really mad at her. A number of people believe that Hamlet might become aware of Polonius's presence immediately before the line "Where's your father?" (Although possibly that may be when Hamlet discovers that Ophelia knows that Polonius is listening, or when he discovers that she has been planted by Polonius). In that case the lines "It hath made me mad", and "I say let us have no more marriages" may be directed to Polonius, the first to help reinforce the illusion that he's crazy and the second to get in a sly dig at Claudius and Gertrude.

Ophelia's father is Polonius, who is Claudius' advisor. Polonius is killed by Hamlet when he is hiding behind a tapestry, spying on Hamlet as he talks to his mother, Gertrude. After Polonius' death, Ophelia goes mad and eventually dies after she falls from a tree into a brook and drowns.
