How big is it?

Marathon Petroleum bought back $4.9B of stock in the twelve months to Jun 30, 2026. At that pace, $5.0B covers about 1.0 years of buybacks.

The amount equals 39% of its free cash flow over the same twelve months ($12.9B).

Its diluted share count is down 5.5% from a year earlier.

An authorization is permission, not a promise: the company can buy less, more slowly, or not at all, and usually doesn't have to say when it buys.
