Oklo vs NuScale (SMR)? — what our data shows
⚡ TradesZ research ·Updated June 23, 2026 ·~2 min read ·Grounded in SEC data
Both SMR and OKLO are betting on small nuclear reactors as the future of clean energy — same big idea, but our data paints a pretty different picture between the two. One has caught the eye of some very serious money, and the other hasn't shown that same signal yet.
What our data shows
Our data shows SMR is playing in the small nuclear reactor space with no red flags, but it hasn't yet attracted the kind of big-fund attention that would show up in our institutional tracking data.
Nuclear SMR
Our data shows 734 major investment funds — including household names like Berkshire Hathaway — have reported owning OKLO, which is a strong sign that serious professional investors are paying close attention to this small nuclear reactor company.

The takeaway
⚪Neutral
If big-name institutional interest matters to you, OKLO has a clear edge in our data — but SMR is still in the same exciting space without that extra stamp of approval from major funds. Neither has any warning flags, so the main difference here really comes down to how much weight you put on who else is already at the table.
But watch out
Smart-money signals lag the market (13F filings ~45 days) and never guarantee direction — always check the latest price and news yourself.
