International Paper Company (ISIN US4601461035) was quoted at USD 35.33 on the NYSE on September 21, 2026, while its market capitalization stood at USD 18.71 billion. The latest market snapshot also recorded a daily gain of 2.32 percent, giving investors a dated reference point for the stock.

Market value sets the frame

The USD 18.71 billion valuation places International Paper among the larger listed packaging companies. For comparison, Packaging Corporation of America had a market capitalization of USD 21.233 billion in the same September 21, 2026 market snapshot, a difference of USD 2.523 billion.

That comparison matters because both companies operate in packaging markets, but valuation alone does not establish equivalent earnings power. The available snapshot identifies International Paper at USD 35.33 and Packaging Corporation of America at USD 232.77, so the share prices themselves are not directly comparable without considering share counts and capital structure.

Packaging remains the central theme

International Paper's current market profile is tied to packaging and containers, while the September 21, 2026 data also listed Packaging Corporation of America under the same broad industry classification. The sector comparison provides a concrete reference for assessing valuation rather than treating the share move in isolation.

The 2.32 percent one-day change and USD 18.71 billion market capitalization are the clearest dated market figures available for International Paper in this report. Together they show both the immediate trading response and the company's equity value as of September 21, 2026.
