# How does Panthalassa’s $140M stack up? Here are the largest Oregon startup funding rounds covered on Silicon Florist

I have a habit of forgetting things. Especially big things. The kind of things that you’d think should be hard to forget. Like nine-figure funding rounds. But that, kids, is why I write things down. So when [Panthalassa raised $140 million today](https://siliconflorist.com/2026/05/04/quietly-raising-one-of-the-largest-rounds-in-portland-startup-history-panthalassa-140m-series-b/), it got me thinking — how does that actually stack up against the largest rounds I’ve covered on Silicon Florist over the years…?

Time for a stroll down memory lane. (For my benefit as much as yours, frankly. Because I could definitely use a refresher.) Here are some of the biggest Oregon rounds I’ve covered, ranked by amount:
