Affirm climbed steadily through regular trading hours, reaching $75.35 late in the session, with the sharpest leg of the rally arriving in the final hours of trading.

A 10% single-day gain on a stock with a market capitalization of roughly $22.4 billion translates to approximately $2 billion in added value. That kind of move in one session is significant for any large fintech, and it signals that buyers were willing to pay up persistently rather than fading the opening pop.

The stock ground higher through the morning with very little pullback, a sign that demand was broad and consistent across the session.

With the session not yet closed at the time of this update, the question for investors is whether the stock can hold the bulk of these gains into the final minutes of trading. Moves of this size that build steadily through the day have a different character than gap-and-fade sessions, and the closing level will matter for how the market interprets the day's move.
