Former U.S. President Barack Obama’s presidential center in Chicago is projected to cost around $1 billion, according to reporting that the price has risen far above early estimates. Initial figures described the project as significantly cheaper, and multiple outlets say the budget has repeatedly increased as construction faced delays and higher-than-expected costs.

The outlets differ slightly in the specific earlier numbers they cite—some reference an initial estimate as low as about $300 million or about $500 million—before later projections moved upward (including figures around the mid–hundreds of millions). The project’s site selection dates to 2016, when Obama chose Jackson Park in Chicago’s South Side for the center. Sources also describe years of building complications that contribute to the change in the final spending outlook.

Overall, the coverage converges on one point: the Chicago campus is entering completion or continued development with a budget that is roughly three times some initial projections, though the cited intermediate and starting estimates vary by outlet.
