Our Top 5 VC Deals of the Week in AI featured funding announcements from Celestial AI, IVIX, Titan, Medallion and EliseAI

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

This week's top-heavy venture capital funding is led by two big deals exceeding the $200 million threshold.

The top reported deal, per FinSMEs, came from Santa Clara, CA-based optical interface developer Celestial AI, which raised a $255 million Series C1 in part to "accelerate commercial deployment of its Photonic Fabric technology," according to its announcement. Celestial's optical interface technology hopes to underpin new generations of AI infrastructure, including data centers, networking and memory systems. Our second-place announcement came from the healthcare and housing space, where New York-based EliseAI brought in a $250 million Series E round. The top five also included companies in the AI infrastructure, crime and fraud prevention, and IT sectors.

Smaller funding raises that did not quite make our top 5 this week included announcements from the software development, fintech, manufacturing and retail spaces.

Below, we highlight the top five venture capital deals, ranked from the highest to the lowest funding amounts, showcasing the companies at the forefront of the AI revolution...
