Sunnyvale’s disclosed rounds are dominated by a clear top end: SiTime’s $1.2B (2026-05-20) is the only disclosed round above $1.0B, with the next-largest disclosed amounts clustering at $1.1B (Cerebras Systems, 2025-10-01), $1.0B (Oklo, 2026-05-13; Figure, 2025-09-21), before dropping to $550M (Antora Energy, 2026-07-30) and $400M (Meshy AI, 2026-07-20). The date window in the most recent rows is also dense: multiple large and mid-size rounds land in 2026, including Antora Energy (Series C, $550M on 2026-07-30) and Meshy AI (Series B, $400M on 2026-07-20), while the oldest shown disclosed entry dates back to 2024-09-23 (Altimate AI is undisclosed; MiLaboratories shows $10M on 2024-10-10). Sector-wise, AI is the largest cluster among labeled categories, with several entries appearing as Series Unknown as well, and there are nine undisclosed rounds among 50 rows, which can materially affect how “size” rankings are interpreted across the list.

Frequently asked
What round-size outliers stand out in Sunnyvale’s disclosed data?
SiTime’s $1.2B (2026-05-20) is the only disclosed round above $1.0B, followed by Cerebras Systems’ $1.1B (2025-10-01) and two $1.0B rounds: Oklo ($1.0B on 2026-05-13) and Figure ($1.0B on 2025-09-21). After that peak band, the next-largest disclosed amounts drop to $550M (Antora Energy, 2026-07-30) and $400M (Meshy AI, 2026-07-20).
How concentrated are funding rounds in the most recent part of the timeline?
The listing spans 2024-09-23 to 2026-07-30, and the top of the disclosed-size ranking includes multiple 2026 closings: SiTime ($1.2B on 2026-05-20), Oklo ($1.0B on 2026-05-13), Antora Energy ($550M on 2026-07-30), and Meshy AI ($400M on 2026-07-20). Even the disclosed $1.0B tier is split across 2026 and 2025 (Oklo in 2026; Figure in 2025-09-21).
Which stage labels appear most often, and is there a “classification gap” that affects sizing?
Several entries are labeled “Series Unknown” across hardware and energy-like categories (e.g., SiTime is Series Unknown at $1.2B on 2026-05-20; Oklo is Series Unknown at $1.0B on 2026-05-13; BIG Fiber is Series Unknown at $250M on 2026-05-19). There are also 9 undisclosed rounds out of 50 rows, so comparisons based strictly on disclosed amounts may under-sample rounds that have no dollar figure.
Does AI dominate the thematic mix of these Sunnyvale-funded companies?
AI is the most repeated labeled category among the shown entries, including large rounds like SiTime (Hardware, but with broader tech proximity) and multiple explicitly AI-tagged companies such as Meshy AI ($400M on 2026-07-20), Straiker ($64M on 2026-06-29), Coram AI ($35M on 2026-06-11), and Dify.AI ($30M on 2026-03-09). The same pattern continues deeper into the list with AI-labeled names like Reka AI ($110M on 2025-07-22) and Lyric ($44M on 2025-08-05).
Are there clearly identifiable funding-size clusters within 2025 versus 2026?
2026 disclosed-size leaders cluster at the upper end of the distribution, including $1.2B (SiTime, 2026-05-20), $1.0B (Oklo, 2026-05-13), $550M (Antora Energy, 2026-07-30), and $400M (Meshy AI, 2026-07-20). In 2025, the top disclosed amounts are $1.1B (Cerebras Systems, 2025-10-01), $1.0B (Figure, 2025-09-21), and other substantial but lower figures like Reka AI at $110M (2025-07-22), indicating 2026’s upper tail is more concentrated in the most recent months shown.
