ATH
All-Time High: the highest price an asset has ever reached.
Definition
All-Time High (ATH) is the highest price an asset has ever recorded. When someone asks what ATH means or what Bitcoin's ATH is, they are referring to exactly that: the historical price ceiling the asset has never exceeded to date. It is one of the most searched terms among investors because it sets the psychological reference point against which everything else is measured.
Bitcoin's all-time highs. Bitcoin has set successive all-time highs across its cycles: around $20,000 in late 2017, roughly $69,000 in November 2021, near $109,000 in January 2025, and its current all-time high of around $126,000, reached in October 2025. Each ATH has been followed by significant corrections — after the October 2025 peak, Bitcoin drew down roughly 50%, in line with prior cycles — and the subsequent recovery beyond the previous high is what defines Bitcoin's long-term adoption pattern.
What the ATH means for Bitcoin treasury companies. For a corporate treasury company, Bitcoin's ATH directly impacts the value of its balance sheet: the closer BTC trades to (or above) its all-time high, the larger the NAV of the reserve and, in turn, the mNAV at which the company trades. That is why moves near the ATH tend to be amplified in treasury company stocks, which behave as leveraged exposure to the underlying asset. And it is why, during deep post-ATH corrections, many treasury companies shift to trading at a discount to NAV.
ATH versus ATL. The opposite of the ATH is the ATL (All-Time Low), an asset's lowest price ever. Together they bound the full range the asset has traded in over its lifetime.
In Context
Strategy accumulated more than 100,000 BTC before Bitcoin broke above its 2021 ATH.
Frequently Asked Questions
