Cycling is a keyword ability that functions specifically while the card is in a player's hand. According to CR 702.29a, cycling gives the card an activated ability that reads: '{cost}: Discard this card. Draw a card.' This ability can be activated any time you have priority and the card is in your hand.
CR 400.1 establishes that a card's abilities are active in whatever zone they function in. For cycling, CR 702.29b explicitly states the ability may only be activated while the card is in a player's hand. So the ability is 'on' the card while it sits in your hand — it doesn't require any prior action like drawing it during that specific turn's draw step.
The moment you draw the card and it enters your hand, the cycling ability is immediately available. There is no additional step or condition needed beyond simply having the card in your hand and having priority at an appropriate time.
Concrete example: You draw Archfiend of Ifnir during your upkeep off a cantrip. You now hold it in your hand. Before your draw step, you can immediately cycle it by paying its cycling cost — you don't need to wait or do anything else first.
One important note: cycling can only be activated at times you could normally play an instant (i.e., when you have priority), unless another effect changes this. But the ability itself is fully present on the card the entire time it remains in your hand (CR 702.29a, CR 702.29b).
