Our Top 5 VC Deals of the Week in AI featured funding announcements from CesiumAstro, Waabi, Genspark, PaleBlueDot AI and Decagon

This week we continue our series on the top 5 VC-funded deals in AI.

We saw a total of 9 fundraising deals come in above the $100 million threshold, continuing very strong and active venture capital activity in 2026.

The top reported deal, per FinSMEs, came from Toronto-based Waabi, which raised $750 million in a Series C, to "accelerate the continued advancement of Waabi’s Physical AI Platform, further accelerate its commercial progress in autonomous trucking, and support expansion into robotaxis" according to its announcement. Waabi also announced a partnership with Uber. Our second announcement is from Austin, Texas-based space and defense connectivity specialist CesiumAstro, which raised $470 million in a Series C of its own to "support expanded manufacturing, accelerated AI-enabled communications development, scaled production of Element, its LEO satellite, and growth of global technical and program teams," according to its announcement. The top five also included companies in the agentic AI, customer service and AI infrastructure spaces.

Smaller funding raises that did not quite make our top 5 this week included announcements from the real estate, defense and robotics sectors.
