Airwallex reached an $11bn valuation in June 2026 on annualised revenue of $1.3bn.

From data centre capacity rationed in Singapore to a four-year freeze on new grid connections in Ireland, this piece examines why compute, cloud access and energy reliability now belong inside the feasibility conversation, not after it. It also makes the case for the other side: where capacity is scarce, securing it early can become a durable competitive advantage rather than just a risk to manage.
