## Question
How many trillion dollar companies will there be on August 31, 2026?
## Description / Resolution Criteria
## Description
As of July 15, 2026, there are 15 trillion-dollar public companies: NVIDIA, Apple, Alphabet (Google), Microsoft, Amazon, TSMC, Broadcom, SpaceX, Saudi Aramco, Meta Platforms (Facebook), Tesla, Samsung, Berkshire Hathaway, Eli Lilly and Micron Technology. The latter three are valued at less than \$1.1 trillion. Whilst four other companies (SK Hynix, JPMorgan Chase, Walmart and AMD) are currently valued above \$850 billion.
`{"format": "metac_reveal_and_close_in_period", "info": {"post_id": 44671, "question_id": 44830}}`
## Resolution Criteria
This question will resolve as the number of public companies which have a market capitalization of over \$1 trillion on August 31, 2026, according to [CompaniesMarketCap](https://companiesmarketcap.com/).
## Fine Print
If CompaniesMarketCap is unavailable or found to be inaccurate, another source may be used.
This question will consider market capitalization following market closure, intra-day values will not qualify.
***
This question's information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/44671) which opened on 2026-07-22 17:00:00. This question will resolve based on the resolution criteria and fine print of the linked original question. However, if this question would resolve differently than the original question, then this question will be annulled. Additionally, if the original question's resolution could have been known before this question opened, then this question will be annulled.
## Options
- 13 or fewer
- 14
- 15
- 16
- 17
- 18
- 19 or more
## Sub-question decomposition (planner)
- (w=0.30) Will all 15 companies currently above $1T (including the marginal ones: Berkshire Hathaway, Eli Lilly, Micron, Samsung, Tesla) still have market caps above $1T at the close on August 31, 2026? — Several incumbents are barely above $1.0-1.1T, so downside drift or a modest market pullback could subtract members, pus
- (w=0.30) Will at least one company not currently above $1T (e.g. SK Hynix, JPMorgan Chase, Walmart, AMD) close above $1T on August 31, 2026? — Four firms sit above $850B, needing only ~15-18% gains in ~6 weeks; the number of new entrants is the main upside driver
- (w=0.20) Will at least two new companies (net of any drop-outs implied) push the total count to 17 or more on August 31, 2026? — Distinguishes the upper tail of the multiple-choice distribution (17+) from the modal 15-16 outcomes.
- (w=0.20) Will broad equity indices (S&P 500 / Nasdaq 100 / semiconductor index) be flat-to-higher on August 31, 2026 relative to mid-July 2026, i.e. no >7% drawdown in mega-cap tech? — The count is dominated by aggregate market direction and AI/semiconductor sentiment over a ~6-week horizon; a correction

## Cross-Market Signals
### Polymarket
- "Will Trump meet with Netanyahu by August 31, 2026?" → Yes: 0.99, Volume: $161.6K
Information gaps:
- No precise mid-July 2026 market caps for the marginal names (Berkshire, Eli Lilly, Micron, Tesla, Samsung)
- No base rate for how often the trillion-club count changes over a ~6-week window
- Discrepancy between question's '15 companies' (July 15) and Motley Fool's '16' (July 24) unresolved
- No index-level price data (S&P 500 / SOX) for July-August 2026
Key uncertainties:
- Whether memory-chip stocks (Micron, Samsung, SK Hynix) hold or lose their ~$1T valuations
- Whether SK Hynix rebounds ~17% from $856B to above $1T by Aug 31
- Volatility of an AI-boom market at stretched valuations over six weeks
- Possible SpaceX-Tesla merger or other structural changes to the count
## Required pre-forecast walkthrough
Before giving probabilities, address these explicitly in your rationale:
(a) The time left until the question resolves.
(b) The status quo outcome — the option most likely if nothing changes from today.
(c) An outcome that would be SURPRISING but plausible.
## Calibration guidance
- **Status quo anchoring.** Good forecasters put extra weight on the status quo option because the world changes slowly most of the time.
- **Leave moderate probability on most options.** Good forecasters don't drop options to ~0% — leave ≥3-5% on every option to account for unexpected outcomes, unless you have strong specific evidence ruling them out.
- Avoid uniform-distribution laziness — most options are not equally likely.
- **Anchor on prediction markets.** If liquid market prices (Polymarket / Kalshi) for these options appear in the evidence, treat them as a strong prior and stay close to them absent specific contrary evidence.
## Output
Return ONLY valid JSON, no markdown fences:

(b) Status quo is 15, the count listed as of July 15, 2026 (though one source suggests 16 by July 24, hinting an entrant may already have crossed). (c) A surprising but plausible outcome is 13 or fewer \u2014 this requires the memory/AI-adjacent marginal names (Micron, Samsung) plus Berkshire and Eli Lilly to slip below $1T together, which a single correlated AI/semis drawdown of ~10% could accomplish; equally surprising on the upside is 18+ if SK Hynix rebounds and JPMorgan, Walmart and AMD all clear the threshold in a melt-up. Quantitatively, five incumbents sit within ~20% of $1T (Berkshire, Eli Lilly, Micron, Tesla, Samsung) with drop probabilities of roughly 10-40%, giving ~1.5 expected exits, while four candidates need only 14-18% gains (SK Hynix, JPMorgan, Walmart, AMD) giving ~1.0 expected entries \u2014 a mean near 14.5 with a standard deviation of ~1.5-2 once cross-sectional correlation is accounted for. The threshold-heavy structure makes the distribution wide and only mildly left-skewed relative to 15, so I spread mass fairly broadly across 13-17 with thin but non-negligible tails. I anchor near 15 for status quo but tilt slightly downward because more marginal incumbents sit near the line than plausible entrants, consistent with the Monte Carlo\u0027s downward mean while discounting its weak credibility.",
