Peter is speaking not Jesus.
In the parallel account in Matthew 16, Jesus tells Peter that he was correct.
62 And the high priest arose and said to Him, “Do You answer nothing? What is it these men testify against You?” 63 But Jesus kept silent. And the high priest answered and said to Him, “I put You under oath by the living God: Tell us if You are the Christ, the Son of God!” 64 Jesus said to him,“It is as you said. Nevertheless, I say to you, hereafter you will see the Son of Man sitting at the right hand of the Power, and coming on the clouds of heaven.”
65 Then the high priest tore his clothes, saying, “He has spoken blasphemy! What further need do we have of witnesses? Look, now you have heard His blasphemy! 66 What do you think?”
They answered and said, “He is deserving of death.”
67 Then they spat in His face and beat Him; and others struck Him with the palms of their hands, 68 saying, “Prophesy to us, Christ! Who is the one who struck You?”(NKJV)
Yes Jesus did confirm to those accusing Him He was the Messiah, the Son of God. Then look at Luke 24 where this is confirmed as well.
Luke 24:
44 Then He said to them,“These are the words which I spoke to you while I was still with you, that all things must be fulfilled which were written in the Law of Moses and the Prophets and the Psalms concerning Me.” 45 And He opened their understanding, that they might comprehend the Scriptures.
46 Then He said to them, “Thus it is written, and thus it was necessary for the Christ to suffer and to rise from the dead the third day, 47 and that repentance and remission of sins should be preached in His name to all nations, beginning at Jerusalem. 48 And you are witnesses of these things. 49 Behold, I send the Promise of My Father upon you; but tarry in the city of Jerusalem until you are endued with power from on high.”(NKJV)

Yes, but he spoke the truth.
Yeshua did his best not to reveal who he was. Had Satan figured out what the plan was, he may well have thwarted it.
