The largest disclosed round in this Palo Alto AI set is SambaNova’s $1.0B on 2026-07-08, which dwarfs the next-largest disclosed amount ($900M at Luma AI on 2025-11-22) and sits far above the rest of the disclosed range (top eight are $250M and higher: Modular at $250M on 2025-09-28 through Luma AI at $900M). The biggest outlier by scale is therefore concentrated at the very top, while the minimum disclosed amount is $100K (Buzz Solutions on 2026-06-04), emphasizing a wide spread between small and mega-rounds within the same geography. Timing is also skewed toward recent months: the page window runs from 2025-07-07 to 2026-07-08, with multiple entries clustered in mid-2026 (for example, Architect at $24M on 2026-06-18, SandboxAQ at $500M on 2026-06-17, and Proception at $11M on 2026-06-29).

Frequently asked
How does the largest disclosed AI round in Palo Alto compare to the rest of the disclosed deals shown?
SambaNova’s $1.0B (2026-07-08) is the only disclosed round on this list above $900M, and it exceeds the next-largest disclosed amount of $900M (Luma AI on 2025-11-22). The next tiers are still high but not in the same league: the top eight disclosed amounts are $250M–$1.0B (e.g., Modular $250M on 2025-09-28; Genspark $275M on 2025-11-20).
Are there meaningful concentration clusters in time within the most recent entries?
Yes. Several large and mid-size rounds are packed into June 2026, including SandboxAQ $500M (2026-06-17), Architect $24M (2026-06-18), and Proception $11M (2026-06-29). The overall window spans 2025-07-07 to 2026-07-08, with the newest single entry on 2026-07-08 (SambaNova $1.0B).
Which entries look like scale outliers on the downside as well as the upside?
On the downside, the smallest disclosed amount is $100K for Buzz Solutions on 2026-06-04. On the upside, the mega-round outlier pattern is explicit: SambaNova’s $1.0B (2026-07-08) sits above the entire disclosed “tail” that tops out at $900M before that (Luma AI, 2025-11-22).
What stage mix dominates this list, and where do ultra-large rounds show up?
Ultra-large disclosed rounds appear at multiple later-stage labels, including Series F (SambaNova $1.0B on 2026-07-08), Series C (Luma AI $900M on 2025-11-22), and Series B/Unknown classifications for other very large amounts such as SandboxAQ $500M (2026-06-17, Series Unknown) and Rhoda AI $450M (2026-03-10, Series A). Smaller disclosed seed/pre-seed entries also appear (e.g., Zive AI $150K on 2026-06-15, Seed; Mesoware $2M on 2026-06-09, Pre-Seed).
Is there a notable pattern in undisclosed funding amounts versus disclosed ones?
Undisclosed amounts account for 7 of 50 rows, while 43 of 50 rows have disclosed amounts. Several of the largest disclosed rounds are still clearly visible as disclosed amounts (e.g., SambaNova $1.0B on 2026-07-08; Luma AI $900M on 2025-11-22), suggesting the biggest scale signals come from disclosed entries rather than the undisclosed group.
