The time complexity of inserting a new node at the beginning of a singly linked list is O(1).

Here's why:

1. In a singly linked list, we always maintain a pointer to the head of the list.
2. To insert a new node at the beginning, we simply create a new node, set its 'next' pointer to the current head, and then update the head to point to the new node.
3. Each of these operations takes constant time, i.e., their time complexity is O(1).
4. Therefore, the overall time complexity of the operation is O(1).
