Bitcoin Stock‑to‑Flow model predicts $440k price by April 2025

Bitcoin’s Stock‑to‑Flow (S2F) model now projects a price peak of $439,981 for Bitcoin on 19 April 2025, a figure that dwarfs the current market price of $62,795.98, which slipped 0.80% in the latest 24‑hour session【1】. The forecast underscores how the model ties Bitcoin’s scarcity to long‑term valuation, a point of focus for investors tracking macro‑level price drivers.

How the S2F model works

The S2F metric divides the total mined Bitcoin (“stock”) by the annual new issuance (“flow”). Using the example in the source, 18 million BTC in circulation divided by an annual flow of 0.33 million yields an S2F of 54, meaning it would take 54 years to double the existing supply at the current mining rate【1】. The model argues that a higher S2F signals greater scarcity, analogous to gold’s high S2F, and thus a higher price potential.

Context and caveats

Historically, Bitcoin’s price has roughly followed the S2F trajectory, though the source notes “occasional fluctuations” that have caused deviations from the curve【1】. The forecast does not guarantee future results; regulatory shifts and macroeconomic conditions could alter the price path, a disclaimer the source explicitly includes【1】. The projected $439,981 peak represents a roughly seven‑fold increase over today’s price, highlighting the model’s long‑term bullish bias.

What to watch

• April 2025 price target – monitor Bitcoin’s trajectory toward the $439,981 level as the date approaches.
• Supply dynamics – track the annual Bitcoin issuance (flow) and any changes to the halving schedule that would affect the S2F ratio.
• Regulatory and macro news – major policy announcements or economic shifts could cause the price to diverge from the S2F projection.

The S2F model’s stark price forecast places Bitcoin’s future value squarely on its scarcity narrative, but the uncertainty around external factors means the actual outcome remains open to debate.
