“Same will happen with Anthropic and OpenAI.”
Our reading, the sentence that was checked:
As with SpaceX, Anthropic and OpenAI will be pushed into indices and index trackers and retail investors will suffer losses when reality catches up.

Conditions

From the speaker
- Same will happen
- Anthropic and OpenAI
- indices
- Index trackers will eat the loss
- retail investors will suffer
- when reality catches up
Our interpretation
- Same refers to the immediately preceding prediction: public offerings followed by index inclusion and losses borne by index trackers and retail holders.
- The prediction covers both Anthropic and OpenAI.
- The reference to relaxed rules concerns accelerated or loosened index eligibility generally; no particular index is named.
- When reality catches up describes the predicted correction, rather than an independently measurable antecedent that must occur before scoring.
- The following separate prediction about 2026 is not imported as a deadline for this sentence.
Counts as supported if: Both companies go public, enter major indices through the described accelerated or relaxed route, and subsequent losses are documented for tracking funds and retail holders at their actual acquisition prices.
Counts as contradicted if: A decisive terminal event makes the predicted sequence impossible for at least one named company, or the completed investment episode establishes that the specified holders did not incur the predicted losses. Temporary gains or delayed listings do not suffice.
Retrospective: these criteria were written after the outcome was public.
Current assessment
Did the forecast come true?
Outcome: Unresolved
The record was checked, and the evidence available by the cutoff does not settle it.
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
Anthropic's October 26, 2026 preliminary prospectus describes a proposed IPO and states that its Class A shares had no prior public market [e1]. On June 4, 2026, S&P retained the eligibility requirements for the S&P 500, MidCap 400 and SmallCap 600 [e2]. These records do not establish the predicted public offerings, index inclusion under accelerated or relaxed rules, and subsequent losses for index trackers and retail investors in both Anthropic and OpenAI [e1, e2]. They also do not document a terminal event preventing that sequence [e1, e2].
Limitations
- Anthropic's preliminary prospectus does not establish a completed offering, index entry or investor losses, and provides no evidence of OpenAI's status.
- The S&P decision covers only the named index family; the forecast names no particular index.
- The packet lacks matched holdings, actual acquisition prices, distributions and subsequent returns for funds and retail investors.
- No deadline or holding period is specified.
Evidence (2 items)
Context only: Anthropic, PBC / U.S. Securities and Exchange Commission,
no public market
Why it matters here: The filing documents preparation for an offering, rather than an already completed public-market and index-loss sequence. It neither confirms nor rules out the forecast.

Context only: S&P Dow Jones Indices,
no changes
Why it matters here: This index family retained its eligibility rules, limiting a blanket relaxed-entry reading. Other index families can have different rules, so this does not contradict the overall forecast.

What would settle it
Offering records and official index notices documenting the predicted entry route for both companies, followed by losses for tracking funds and retail holders measured from their actual acquisition prices, would support the forecast. A terminal event permanently preventing the sequence for either company, or a completed investment episode establishing that the specified holders did not incur the predicted losses, would contradict it.
