Satellite‑imagery firm SynMax says the United States is clearing land for new AI‑focused data centres faster than before. The company estimates total installed capacity will climb from about 11 GW in 2025 to between 16 GW and 18 GW in 2026. That is a bit higher than earlier forecasts, but still far short of the more than 80 GW some planners have announced for 2028.

Investment bank Jefferies warns that the pace of construction is limited by three factors: permits, power access, and especially the supply of packaged AI accelerators. Advanced packaging – the step where chips are combined with high‑bandwidth memory – is a bottleneck. Most US‑made dies still need to be sent to Taiwan for this step, creating a choke point.

## How much can current packaging support?

SynMax calculates that existing advanced‑packaging capacity can handle accelerators that draw roughly 13 GW of power. After accounting for CPUs, memory, cooling and other loads, that translates to about 17.5 GW of total datacenter power. Two new packaging projects slated for 2027 could add another 6 GW, pushing the practical ceiling into the low‑20 GW range unless capacity expands faster.

## Why the limit matters

If packaging cannot keep up, new AI workloads may be throttled or delayed, affecting cloud‑service pricing and availability. Operators in power‑tight regions like Texas may have to accept occasional curtailment – temporary power cuts – to stay on the grid, which can complicate service‑level agreements.

## The facts

- SynMax estimates US AI‑datacenter capacity will rise from ~11 GW in 2025 to 16‑18 GW in 2026.
- Jefferies reports only half of the 2026 capacity is under construction and up to 80 % of the 2028 pipeline has not started.
- Current advanced‑packaging capacity can support about 13 GW of accelerator power, or ~17.5 GW of total datacenter power.
- Two new packaging projects expected in 2027 could add roughly 6 GW, setting a practical ceiling in the low‑20 GW range.
- The report notes most packaging still occurs overseas, mainly in Taiwan, creating a supply choke point.

## Why it matters

For everyday users, slower rollout of AI‑ready data centres could keep cloud‑service costs higher and limit the speed at which new AI features arrive. In power‑constrained states, operators may face occasional power cuts, which could affect the reliability of services you depend on.
