Analysts split on Google's merchant TPU: $100B vs $252.7B by 2028 forecasts

Analyst Beth Kindig sums up wildly divergent forecasts for Google's merchant TPU business: Barclays sees revenue ramping from $20B in 2026 to $252.7B by 2028, while Piper Sandler ($104B) and JP Morgan ($100B+) are far more conservative. Google booked first TPU systems revenue in Q2 on a small base, and Cloud revenue growth accelerated to 82% ($24.8B vs $22.5B expected). The piece argues custom silicon cuts Google's cost per token and opens a revenue stream beyond cloud rentals, with new TPU 8t/8i claiming big perf-per-dollar gains over TPU v7 Ironwood — and TPU strategy likely dominating next week's Q3 earnings call.
