Fact check: What was the closing price of GOOG stock on September 25, 2025?

Executive Summary — Direct Answer and Immediate Limitation

The three provided analyses and their underlying documents do not contain the requested fact: the closing price of Alphabet Inc. Class C (GOOG) on September 25, 2025 is not present in any of the supplied materials. The items supplied include a privacy/terms page and partial historical-price extracts covering spring 2025, but none report market data for the September 25, 2025 trading day, so the closing price cannot be confirmed from these sources ^{[1] [2] [3]}. Below I summarize what the supplied materials claim, identify the information gap, explain how to retrieve a verifiable closing price, and note verification pitfalls and possible agendas in common market-data providers.

1. What the supplied materials actually claim — a disappointing absence of the target date

All three supplied analyses explicitly state that their documents do not include the September 25, 2025 closing price. One appears to be a corporate policy or site page that carries a label referencing Alphabet historical prices yet contains no price data for that date ^[1]. A second item provides stock-price snippets for Alphabet Class A (GOOGL) but only through May 2025 and hence lacks September 2025 pricing ^[2]. The third covers Class C (GOOG) price history but only for a late-April to late-May 2025 window and therefore omits the requested September 25, 2025 closing value ^[3]. The supplied evidence is incomplete.

2. Why that absence matters — precision and auditability in market facts

Prices for tickers like GOOG can vary materially between dates and between data vendors depending on corporate actions, splits, or late corrections; a single-day closing price must be sourced to an auditable historical record. The supplied items fail to meet that standard because they neither cover the date in question nor include an explicit archival stamp for September 25, 2025. For questions about market prices, the standard is to cite a timestamped exchange or market-data vendor record showing the exact close, which none of these materials provide. The absence of a primary, date-specific entry prevents independent verification from the supplied documents ^{[1] [2] [3]}.

3. Where authoritative closing prices are normally found — practical, verifiable options

To obtain and verify a historical closing price for GOOG on September 25, 2025, the accepted approach is to consult timestamped records from regulated market venues or established financial-data vendors. Typical authoritative places include: exchange historical-data pages (e.g., Nasdaq/NYSE data feeds), consolidated tape archives, major financial-data services (e.g., Bloomberg, Refinitiv/Reuters), and well-known consumer-facing historical quotes on finance portals. For auditability, prefer a source that displays the close, the currency, the time zone, and any corporate-action adjustments such as splits or dividends. Document the exact URL, retrieval time, and any adjustment notes.

4. How to cross-check and resolve discrepancies across vendors

Different vendors can report different adjusted closing values due to corporate-action adjustments or corrections issued after market close; cross-check at least two independent, authoritative sources when you retrieve the number. Compare an exchange-native feed (which records the raw close) to a professional data terminal (which may show adjusted close). If the two differ, examine the vendor’s notes on adjustments or restatements. Keep copy of the page or a screenshot with timestamps, because intraday corrections and data-provider backfills are common and can change archived values in vendor databases.

5. Common pitfalls and the agendas behind data presentation

Market-data vendors and portals sometimes display multiple price fields—last trade, close, adjusted close, and close in different currencies—without clear labels; this can create apparent disagreement. Vendor agendas can include promoting premium services (restricting detailed historical data) or driving traffic by making full archives available only to subscribers. Public-facing pages may show truncated date ranges, and site structures labeled “historical prices” do not guarantee full coverage. Treat any single vendor’s historical table as potentially incomplete and corroborate across different classes (GOOGL vs GOOG) because Alphabet maintains Class A and Class C listings that can have different trading patterns.

6. Recommended next steps you can act on immediately

I cannot state the September 25, 2025 closing price based on the supplied evidence. To resolve this precisely, pull the historical quote for GOOG from one or more authoritative sources and capture the following fields: date, close price, currency, and any adjustment flag. Archive the page or download the CSV with timestamp. If you want, provide one authoritative screenshot or CSV and I will confirm consistency, flag adjustments, and explain any discrepancies between sources.

7. Bottom line — what we know and what remains to be done

From the supplied materials, the requested closing price for GOOG on September 25, 2025 is not present and therefore cannot be affirmed. The correct path is to consult timestamped exchange or reputable market-data archives, capture the close and adjustment notes, and cross-check across vendors to ensure auditability. Once you supply a concrete vendor output or allow me to fetch the data, I will compare multiple sources, identify any adjustments, and provide a firm, sourced closing price with provenance and any caveats.
