U.S. states that previously incentivized data centers are now reconsidering their stance by withdrawing sales tax breaks, a move that could significantly increase the operational costs of AI computing. Arizona, Illinois, and Ohio are among the states that have paused or narrowed these tax incentives, which cover key components like computer equipment and server gear. The repeal of such incentives is expected to raise costs by approximately 7% or more, potentially increasing the price of IT equipment for a 1-gigawatt data center by billions of dollars.

This comes as NVIDIA’s market position is under scrutiny, with prediction markets assessing its likelihood of being the largest company by market cap by the end of August 2026. Current market pricing indicates a strong expectation that NVIDIA will achieve this, with a 79.5% YES probability, although the cost pressures from increased data center expenses might affect these odds.
