Here is a hint of what has happened to the Ark of the Covenant.
Jeremiah 3:16
16In those days, when you multiply and increase in the land, declares the LORD, no longer will they say, The ark of the LORDs covenant. It will never come to mind, and no one will remember it or miss it, NOR WILL ANOTHER ONE BE MADE.
[1] One finds in the records that Jeremiah the prophet ordered those who were being deported to take some of the fire, as has been told, [2] and that the prophet after giving them the law instructed those who were being deported not to forget the commandments of the Lord, nor to be led astray in their thoughts upon seeing the gold and silver statues and their adornment. [3] And with other similar words he exhorted them that the law should not depart from their hearts.
[4] It was also in the writing that the prophet, having received an oracle, ordered that the tent and the ark should follow with him, and that he went out to the mountain where Moses had gone up and had seen the inheritance of God. [5] And Jeremiah came and found a cave, and he brought there the tent and the ark and the altar of incense, and he sealed up the entrance. [6] Some of those who followed him came up to mark the way, but could not find it. [7] When Jeremiah learned of it, he rebuked them and declared: The place shall be unknown until God gathers his people together again and shows his mercy. [8] And then the Lord will disclose these things, and the glory of the Lord and the cloud will appear, as they were shown in the case of Moses, and as Solomon asked that the place should be specially consecrated. (2 Maccabees 2:1-8)
So, no. That could not be any sort of hint as to where it is today.
On the nose.. Jeremiah hid it and intended it to stay hidden because it had become an object of idolatry itself.
I’ve read that a verse in Jeremiah indicates the Ark of the Covenant will be found in the end times (possibly Ireland). The sons of Zedikiah were slain who were heirs to the throne of David, but not his daughters who escaped to Egypt. They had to flee Egypt after a warning from God.
In the ancient annals of Ireland, there is mention of a white haired patriot (Jeremiah) bringing, a harp, an ark, and a stone.
