The base rate (sq3) sets a low anchor for any two-month window, while sq1 and sq2 capture whether the specific active speculation (Nike/Berkshire) or another reconstitution actually converts into a confirmed announcement in the window; these are correlated signals blended via weighted average.

## Question
Will another company get dropped from the Dow Jones Industrial Average in July or August 2026?
## Description / Resolution Criteria
## Description
CNBC (June 23, 2026) [Alphabet added to Dow Jones Industrial Average, replacing Verizon](https://www.cnbc.com/2026/06/23/alphabet-verizon-dow-djia.html):
> Alphabet will replace Verizon in the Dow Jones Industrial Average, S\&P Global said Tuesday, further expanding mega-cap technology’s presence in the blue-chip average.
> S\&P Global said the Google parent’s Class A shares, which trade under the ticker GOOGL, will take Verizon’s spot in the 30-stock index ahead of the start of Monday’s trading. Shares of Alphabet rose about 1% after the bell Tuesday following the announcement.
> The California-based company will join mega-cap technology peers Nvidia, Amazon, Apple, and Microsoft in the Dow. S\&P Global said Alphabet’s inclusion will bolster the index’s exposure to themes including artificial intelligence, cloud infrastructure, and advertising.
In the wake of the announcement, there has been other speculation such as by [Barron's](https://finance.yahoo.com/m/d868ebcd-ca45-3467-aef7-ffd4c0a62cb7/could-nike-get-the-boot-from.html) that Nike may be dropped from the Dow and replaced by Berkshire Hathaway. 
`{"format": "metac_reveal_and_close_in_period", "info": {"post_id": 44244, "question_id": 44253}}`
## Resolution Criteria
This question resolves as **Yes** upon any official announcement or confirmation or [credible source ](https://www.metaculus.com/faq/#definitions)reporting after June 30, 2026 and before September 1, 2026 that one of these companies will no longer be a component of the Dow Jones Industrial Average (DJIA) index:
3M 
Alphabet
American Express
Amgen
Amazon
Apple
Boeing
Caterpillar
Chevron
Cisco
Coca-Cola
Disney
Goldman Sachs
Home Depot
Honeywell
IBM
Johnson & Johnson
JPMorgan Chase
McDonald's
Merck
Microsoft
Nike
Nvidia
Procter & Gamble
Salesforce
Sherwin-Williams
Travelers Companies
UnitedHealth Group
Visa
Walmart
If no such announcement or reporting occurs before September 1, 2026, this question resolves as **No**.
## Fine Print
Although removals from the DJIA are generally effective immediately in order to forestall frontrunning, this is not a requirement for this question. All that is required is for there to be an announcement or confirmation before in the time listed that a company will be removed from the index at any point in time. Therefore this question will resolve based on the announcement or confirmation, not on the actual removal date.
***
This question's information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/44244) which opened on 2026-06-26 18:00:00. 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.
## Sub-question decomposition
- (w=0.50) Will there be an official S&P Global/DJIA announcement between July 1 and August 31, 2026 removing a current Dow component? — This is the primary resolution pathway — an official index reconstitution announcement in the window.
- (w=0.30) Will credible reporting (e.g., Barron's, CNBC) specifically about Nike being replaced by Berkshire Hathaway materialize as a confirmed removal announcement in the window? — The Nike/Berkshire speculation is the most concrete named candidate, driving elevated probability.
- (w=0.20) Does the historical base rate of DJIA changes occurring within any given two-month window (especially right after a prior change) suggest another removal is likely? — Dow reconstitutions are infrequent and rarely clustered; base rates anchor the estimate.
Combination rule: **weighted_average**

## Cross-Market Signals
### Polymarket
- "Will there be no change in Fed interest rates after the July 2026 meeting?" → Yes: 0.92, Volume: $7.9M
- "Will the Fed decrease interest rates by 25 bps after the July 2026 meeting?" → Yes: 0.01, Volume: $6.0M

- "Will the Fed decrease interest rates by 50+ bps after the July 2026 meeting?" → Yes: 0.00, Volume: $7.0M
Information gaps:
- No historical data on how often DJIA changes cluster within 2 months of a prior change
- No indication S&P has scheduled or is actively considering another change in July-August 2026
- No confirmed reporting of an imminent Nike removal timing
- Whether S&P prefers to bundle changes vs. make them individually
Key uncertainties:
- Whether Nike's low price triggers a near-term rather than 12-month removal
- Whether S&P makes back-to-back changes shortly after Alphabet/Verizon
- Timing sensitivity — analyst 'next 12 months' vs. the 2-month window
- Possibility of an unexpected non-Nike reconstitution
## Required pre-forecast walkthrough
Before giving probabilities, walk through these explicitly:
(a) The time left until the question resolves.
(b) The status quo outcome — what happens if nothing changes from today.
(c) A brief scenario that results in NO.
(d) A brief scenario that results in YES.
## Calibration guidance
- **Estimate each sub-question in isolation.** Do not let your answer to one sub-question anchor your answer to another. This is the core of Fermi decomposition — independence forces more careful reasoning per factor.
- **Anchor on the status quo.** Require strong specific evidence to move far from it.
- 0.05 / 0.95 require strong, multi-source evidence. Avoid >0.97 or <0.03 unless the outcome is already settled or near-tautological — overconfident misses are punished heavily by the log score.
- **Anchor on prediction markets.** If liquid market prices (Polymarket / Kalshi) or a community forecast appear in the evidence, treat them as a strong, well-calibrated prior. Your final estimate should rarely sit more than ~15 percentage points from a liquid market on the SAME question — move further only with specific evidence the market lacks.
- **Treat research as fallible, not ground truth.** A single-source or "very recent" claim — especially one the evidence flags as unverified, possibly AI-generated, or low-credibility — must not drive you to near-certainty. When a load-bearing fact is unverified, keep at least 10-15% on the chance it is wrong.
- **Also provide a holistic estimate** — your overall gut feeling about the main question, BEFORE you see the mathematical combination. This serves as a sanity check: if the Fermi result and holistic estimate diverge wildly, something is wrong.

However, back-to-back changes within weeks of a prior one are historically rare, and the concrete speculation is framed on a 12-month horizon, not imminent.",

"description": "## Description\nCNBC (June 23, 2026) [Alphabet added to Dow Jones Industrial Average, replacing Verizon](https://www.cnbc.com/2026/06/23/alphabet-verizon-dow-djia.html):\n\n\u003e Alphabet will replace Verizon in the Dow Jones Industrial Average, S\\\u0026P Global said Tuesday, further expanding mega-cap technology\u2019s presence in the blue-chip average.\n\n\u003e S\\\u0026P Global said the Google parent\u2019s Class A shares, which trade under the ticker GOOGL, will take Verizon\u2019s spot in the 30-stock index ahead of the start of Monday\u2019s trading. Shares of Alphabet rose about 1% after the bell Tuesday following the announcement.\n\n\u003e The California-based company will join mega-cap technology peers Nvidia, Amazon, Apple, and Microsoft in the Dow. S\\\u0026P Global said Alphabet\u2019s inclusion will bolster the index\u2019s exposure to themes including artificial intelligence, cloud infrastructure, and advertising.\n\nIn the wake of the announcement, there has been other speculation such as by [Barron\u0027s](https://finance.yahoo.com/m/d868ebcd-ca45-3467-aef7-ffd4c0a62cb7/could-nike-get-the-boot-from.html) that Nike may be dropped from the Dow and replaced by Berkshire Hathaway.\u0026#x20;\n\n`{\"format\": \"metac_reveal_and_close_in_period\", \"info\": {\"post_id\": 44244, \"question_id\": 44253}}`\n\n## Resolution Criteria\nThis question resolves as **Yes** upon any official announcement or confirmation or [credible source ](https://www.metaculus.com/faq/#definitions)reporting after June 30, 2026 and before September 1, 2026 that one of these companies will no longer be a component of the Dow Jones Industrial Average (DJIA) index:\n\n3M\u0026#x20;\nAlphabet\nAmerican Express\nAmgen\nAmazon\nApple\nBoeing\nCaterpillar\nChevron\nCisco\nCoca-Cola\nDisney\nGoldman Sachs\nHome Depot\nHoneywell\nIBM\nJohnson \u0026 Johnson\nJPMorgan Chase\nMcDonald\u0027s\nMerck\nMicrosoft\nNike\nNvidia\nProcter \u0026 Gamble\nSalesforce\nSherwin-Williams\nTravelers Companies\nUnitedHealth Group\nVisa\nWalmart\n\nIf no such announcement or reporting occurs before September 1, 2026, this question resolves as **No**.\n\n## Fine Print\nAlthough removals from the DJIA are generally effective immediately in order to forestall frontrunning, this is not a requirement for this question. All that is required is for there to be an announcement or confirmation before in the time listed that a company will be removed from the index at any point in time. Therefore this question will resolve based on the announcement or confirmation, not on the actual removal date.\n\n***\nThis question\u0027s information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/44244) which opened on 2026-06-26 18:00:00. 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\u0027s resolution could have been known before this question opened, then this question will be annulled.",
