And so as a result of that, they're able to actually take the MRI images, and they can do fewer and fewer scans to get the equivalent resolution. So two things will happen. One is the scan time will come down, right? So it was an hour and a half. Now it's sort of right under an hour. It can probably be as low as 40 minutes, which is relatively tolerable for most people. And then the cost will come down into the hundreds of dollars because you'll be able to very rapidly assess.View on YouTube
Chamath argued that as companies like Prenuvo gathered more data and improved ML, two things would happen: (1) full‑body MRI scan times would fall from ~60–90 minutes to roughly 40 minutes, and (2) prices would drop from ~$1,500–$2,500 into the low hundreds of dollars while preserving diagnostic quality.
For Prenuvo itself, neither target has been reached as of late 2025. Prenuvo markets its whole‑body MRI as “fast (under 1 hour)” with typical scan times around 45–60 minutes, not ~40 minutes.(prenuvo.com) Its current U.S. pricing for a comprehensive whole‑body scan is about $2,499, with enhanced packages at $3,999–$4,499, i.e., still in or above the original $1,500–$2,500 range rather than in the low hundreds.(prenuvo.com) Industry reporting likewise places Prenuvo’s full‑body scans around $2,400–$2,500.(bodyspec.com)
Across the broader “full‑body MRI” market, typical consumer preventive scans remain roughly $1,000–$2,500, with some lower‑cost offerings like SimonMed’s simonONE Body scan at ~$650 and about an hour of scanner time—cheaper, but still not “low hundreds.”(goodhousekeeping.com)
At the same time, newer AI‑driven services such as Ezra/Function Health have introduced substantially faster and cheaper MRI‑based screening. Function Health now offers an MRI scan (covering head, neck, abdomen, and pelvis) that takes about 22 minutes and costs $499, explicitly described as a reduction from earlier 60‑minute, ~$1,500 scans, and marketed as screening for hundreds of conditions.(functionhealth.com) However, this product does not cover the entire body in the same way as Prenuvo’s flagship scan (it omits chest, lungs, and limbs), and there is not yet clear, independent evidence that its diagnostic performance is fully equivalent to longer, more expensive protocols.
Because Chamath’s prediction was framed around Prenuvo‑style full‑body MRI but the outcomes differ depending on which provider and definition of “full‑body” you use—and because equivalence of diagnostic resolution is not yet well established—the evidence is mixed rather than clearly validating or falsifying his claim.
