Every row, checked against its source

What each label means

• Confirmed: The brand is named on the cited page.
• Couldn’t check: The cited page blocked our check, has been taken down, or shows sponsors as logos we cannot read.
• Mentioned, not as sponsor: The cited page names the brand, but nothing near it says it paid for the slot.
• Not on source: The cited page loaded, but the brand is not named on it.
• Detection tool only: Only a third-party sponsorship-detection tool lists this; no independent page confirms it.

Every row carries one of these, confirmed rows included. Counts on the site use confirmed rows plus rows from trade press and official pages we could not re-read, the two kinds of source a hand audit found 3 to 6% wrong. Everything else sits in a closed "could not confirm" list at the end of each page. For podcasts and YouTube, the brand must sit next to words like "sponsored by", "use code" or "% off" to count as confirmed.

The check confirms the brand is on the page. It does not confirm every detail of the row (tier, year, amount).

Hand check, 5 October 2026

We read 40 random rows against their pages by hand:

• Confirmed, trade press and official pages in India and the Gulf: 10 of 10 right.
• Confirmed, Wikipedia only: 5 of 6 right. The miss was a team's own car model listed as its sponsor.
• Confirmed, podcasts: 8 of 10 right. A presenter's name and a host's own product were read as sponsors.
• Mentioned, not as sponsor: 5 of 6 right. The miss, a sponsor given only as a link with the show's name, is now caught.
• Not on source: 8 of 8 pages really do not name the brand. For podcasts and Wikipedia that often means the page has changed since.

What we leave out, and why

India and the Gulf are the product. International rows (mostly podcasts, YouTube and foreign clubs) stay in the Sponsorships table and on Indian and Gulf brands' own pages, not in counts or rankings. Rows whose "brand" was really a race or a tournament name were dropped. We publish no pages about individual marketers: they appear only as a dated, sourced line on their brand's page, or as credits they add themselves. We publish no celebrity fees and no estimated deal values; a value appears only when the source printed it.

Corrections

Brands and organisers can claim their page to correct it. Anyone can report an error from any page, or write to sg@c4e.in. We aim to fix confirmed errors within 7 days and note the change.
