The largest disclosed round in this Sunnyvale set is SiTime’s $1.2B (Series Unknown) on 2026-05-20, and it dwarfs the next-highest disclosed amounts that sit at $1.1B (Cerebras Systems, 2025-10-01) and $1.0B (Oklo, 2026-05-13; Figure, 2025-09-21). At the other extreme, the smallest disclosed amount is $140K for Maui Imaging (Series Unknown) on 2026-01-13, making the disclosed range in these rows span from six figures to the billion-dollar level.
Date-wise, activity is concentrated in a dense late-spring/summer window: within roughly the last six weeks shown (from 2026-04-29 through 2026-06-29), there are multiple large AI and infrastructure rounds (e.g., Scout AI $100M on 2026-04-29; Coram AI $35M on 2026-06-11; Straiker $64M on 2026-06-29). Sector-wise, AI appears in 25 of the 50 rows, while “Series Unknown” appears in 10 rows and “undisclosed” appears in 6 rows, creating recurring comparability gaps around stage and deal sizing.

Frequently asked
What are the biggest disclosed rounds in this Sunnyvale list, and how do they stack up against the rest?
SiTime’s $1.2B (Series Unknown) on 2026-05-20 is the only disclosed round above $1B in these rows; the next-largest disclosed amounts are $1.1B (Cerebras Systems, 2025-10-01) and $1.0B (Oklo on 2026-05-13; Figure on 2025-09-21). The rest of the disclosed deals generally cluster well below that level (for example, $250M BIG Fiber on 2026-05-19 and $140K Maui Imaging on 2026-01-13 mark the high-to-low end).
Are there time clusters where more funding closes, based on the most recent entries shown?
Yes. Between 2026-05-13 and 2026-06-16 alone, the list includes several high-velocity AI and hardware/infrastructure rounds such as Oklo $1.0B (2026-05-13), Coram AI $35M (2026-06-11), and YouArt $500K (2026-06-16), plus multiple mid-size AI deals (e.g., Sekai $20M on 2026-06-01; Straiker $64M on 2026-06-29).
Which sectors are most represented, and does the list show a clear mix skew?
AI is over-represented: it appears in 25 of 50 rows (e.g., Straiker $64M on 2026-06-29; Lyric $44M on 2025-08-05; Acuvity $9M on 2024-09-05). Non-AI sectors such as Hardware and Biotechnology appear but with fewer rows, while “Other” only shows up once (Modiqo, Pre-Seed, $3M on 2026-05-28).
How much of the list is hard to compare because the stage or amount is not disclosed?
10 of 50 rows are labeled “Series Unknown” (e.g., SiTime on 2026-05-20 for $1.2B; Cerebras Systems on 2025-10-01 for $1.1B; Oklo on 2026-05-13 for $1.0B), and 6 of 50 rows show “undisclosed” amounts (e.g., Noble Machines on 2026-03-04; Zibra AI on 2026-01-07; ANAFLASH on 2024-11-19). Together, these create repeated gaps right where an analyst would normally compare deal size and stage.
Is there an outlier that is both unusually large and not purely AI, suggesting different capital intensity drivers?
Beyond AI’s $20M–$110M range in multiple entries (e.g., Sekai $20M on 2026-06-01; Reka AI $110M on 2025-07-22), the standout outlier is Hardware-backed capital intensity: SiTime’s $1.2B (2026-05-20) and BIG Fiber’s $250M (2026-05-19) sit far above most other disclosed rounds. On the low end, Maui Imaging’s $140K (Biotechnology, 2026-01-13) provides the opposing extreme in disclosed sizing.
