Pundit ClaimsAI claims by Gary Marcus and Ed Zitron, with the evidence

“NVidia is down by a third, so far in 2025. (Far more than the stock market itself.)”

Scaling is over, the bubble may be deflating, LLMs still can’t reason, and you can’t trust Sam, paragraph 4. The full statement is at the source.

Our reading, the sentence that was checked:

Nvidia's stock fell by about a third in 2025 through early April, far more than the overall market.

Conditions

  • year to date 2025 (qualifier, stated by the speaker)

From the speaker

  • NVidia is down by a third
  • so far in 2025
  • Far more than the stock market itself

Our interpretation

  • Read 'a third' as an approximate description of the share-price decline, consistent with the supplied normalized proposition.
  • Use conventional calendar-year-to-date price performance, measured from the preceding year-end close through April 4, the last trading close before the Sunday post.
  • Use the S&P 500 price index as an ordinary broad US market comparator.
  • This is a traded-security price-return claim, rather than a claim about Nvidia's corporate finances; metric_scope is therefore null.

Counts as supported if: Nvidia's year-to-date share-price decline is approximately one third and materially exceeds the broad market's decline over the same interval.

Counts as contradicted if: Nvidia's decline is materially smaller than approximately one third, or does not substantially exceed the broad market decline.

Retrospective: these criteria were written after the outcome was public.

Current assessment

Was it true for the period described?

Outcome: Supported

The dated evidence matches what the claim committed to, under the criteria frozen before grading.

Scored on a plain reading. The speaker named no measure for this claim, so it was judged on the reading an informed reader would take, stated below under our interpretation. Both reviews had to find that reading fair.

Rationale

Through April 4, Nvidia was down roughly 30%, compared with 13.7% for the S&P 500. That supports the ordinary approximate reading of 'a third' and clearly supports the market comparison. The wording slightly overstates the reported decline if read precisely.

Limitations

  • The supported result depends on accepting approximate language: 30% is not exactly one third.
  • The S&P 500 is an evaluator-selected benchmark.
  • The Nvidia figure comes from financial reporting rather than a directly retrieved exchange price series.

Evidence (2 items)

  • Supports the claim: TheStreet, syndicated by Yahoo Finance,

    down roughly 30% year-to-date.

    Why it matters here: The reported decline is close to one third, though it is not literally 33.33%. Financial reporting is used because the historical-price filing could not be read.

  • Supports the claim: Morgan Stanley Wealth Management, using Bloomberg market data,

    lost 13.7%

    Why it matters here: The matching broad-market decline was substantially smaller. Nvidia's approximately 30% decline was about 2.2 times as large.

    Secondary summary
    Arithmetic
    30 / 13.7 = approximately 2.19; 30 - 13.7 = approximately 16.3 percentage points (inputs: e1: Nvidia year-to-date decline approximately 30%; e2: S&P 500 year-to-date decline 13.7%; Ratio rounded to one decimal place in the explanation; precision limited by the approximate Nvidia figure.)
