AI spending keeps climbing, and that's good news for the three chipmakers sitting at the center of it.

• Bank of America raised its forecast for the AI data center market through 2030 to $2.2 trillion, lifting expected yearly growth from 33% to 40%.
• TSMC now makes more than 72% of the world's made-to-order chips, locking in its lead as the factory everyone depends on.
• Nvidia still owns the AI computing chip market, with revenue expected to grow sharply into 2027.
• Micron is riding a memory chip shortage, which gives it pricing power it hasn't had in years.
• The bet rests on one thing: big tech keeping its data center budgets high for years, not quarters.

Outlook: The data center building boom is expected to run through 2030, so all three should keep benefiting unless AI spending suddenly cools.
