ONE Friday Fights 166 & The Inner Circle 26 took place on August 14, 2026 at Lumpinee Stadium, Bangkok. This source-led report turns 14 active official-source bout rows into a readable result inventory, including no championship classification inferred beyond the source rows. Every named winner, method, round and time below comes from the retained promotion record. When a field is absent, the report leaves it absent instead of completing the story from assumption.
Ten of the fourteen retained outcomes were decisions: nine unanimous and one split. The four finishes comprised three knockouts and one submission, so the record shows a decision-heavy card without reducing every contest to the same ruleset.

What the retained pattern shows
Across 14 results, 10 are classified here as decisions and 4 as stoppages by the stored method wording. Every retained method falls into one of those two broad descriptive buckets. These totals are descriptive navigation aids. They do not measure entertainment value, competitiveness, judging quality or the technical merit of a performance, and they do not change the exact method text shown beside each fight.
The combined event name matters here because the source presents ONE Friday Fights and The Inner Circle as one inventory. This report keeps all fourteen results under that official event identity rather than splitting or duplicating the card.
Sources, freshness and limitations
The local source row was last observed on August 29, 2026. Primary evidence: ONE Championship official event or results page. The complete retained card is available on the Fights Now event record. Verification here means the result fields match the retained official-source record; it is not a claim that promotional commentary is independent analysis. Corrections, overturned decisions and later source changes should be handled through the normal correction workflow. No featured image is attached because this batch has not performed a separate image-rights review.
This report is intentionally narrower than a conventional recap. The local inventory does not contain a complete independent account of momentum, tactics, injuries, crowd response or disputed moments, so none of those are invented. It also avoids presenting a source's marketing language as Fights Now's conclusion. Readers get a durable result index, direct access to the promotion source and a clear boundary around what the retained evidence can and cannot establish.
