As Bitcoin reaches a recent peak, analysts seek the advice of quite a lot of charting instruments to foretell the trajectory of main digital currencies. Amongst these are the well-known rainbow charts and inventory circulate (S2F) fashions. The next evaluation examines the present value of BTC via the lens of those two frameworks.
The Bitcoin mannequin reveals explosive development, however does actuality cooperate?
At present, Bitcoin (BTC) is buying and selling at $103,046 on Friday, Could ninth, with many observers foreseeing a brand new document stage earlier than the yr. Market contributors will overturn the charts with ardent scrutiny, however analysts seek the advice of a forecast mannequin to determine the following transfer within the asset. This evaluation examines two particular charting strategies and prediction frameworks that may present insights regardless of these instruments being beforehand known as incomplete.

Creator of Plan B, Inventory-to-Stream (S2F) Bitcoin pricing mannequin.
Inventory-to-flow (S2F)
The Inventory-to-Stream (S2F) mannequin quantifies shortages by linking current provides (shares) to annual manufacturing (flows). Within the case of Bitcoin, “circulate” refers to a newly mined coin every year. When Bitcoin provide is halved each 4 years, the circulate decreases and the scarcity is intensified. It’s hypothesized that growing rarity results in strain on costs.
At present, the value trajectory is within the shades of crimson to orange, that means that it handed half the occasion a yr in the past (crimson = 0 days, half, blue = previous few days). Traditionally, these phases noticed a violent value of half the sparks rise over the following 12-18 months. The proximity of Bitcoin’s market value to S2F projection signifies that present belongings are extra devoted to the mannequin than in earlier cycles.

Advances the S2F sample after historic demolition will predict exponential climbing, probably touchdown round $275,000 by the second half of 2026. Its trajectory displays a uncommon paper on the coronary heart of S2F. This dynamic is being deployed in firms equivalent to Alternate-Taded funding and methods like earlier MicroStrategy.
This mannequin offers visible readability and demonstrates historic consistency, nevertheless it ought to be thought-about in collaboration with different metrics because it doesn’t take into consideration exterior market shocks or macroeconomic disruptions from wars and Trump’s commerce selections. Like all fashions and technical evaluation, S2F has seen a good portion of the criticism.
Rainbow Chart
In accordance with the unique Rainbow Chart, Bitcoin costs for the following 18 months may go from the “FOMO” band to “Is that this a bubble?” zone. That trajectory is simply above $100,000 and is shifting in direction of the $290,000-$365,000 vary by the second half of 2026. The colored band represents long-term log development, and as Bitcoin follows historic patterns, it strikes earlier than coming into extra speculative territory earlier than it passes these thresholds of feelings. Rainbow charts aren’t excellent both and shouldn’t be towards different markets or different financial components.

Unique rainbow chart from Could 9, 2025.
It’s widely known that the Bitcoin Rainbow Chart has been compiled and adjusted to mirror market maturity and extra measured development pathways. The preliminary model relied on scarce knowledge and assumed a sudden speculative value enhance. As extra knowledge emerged after which tapered in subsequent cycles, the chart was tuned with enhanced statistical strategies to keep away from a extra intently matched and extra intently aligned with precise efficiency.
These enhancements will make the chart extra affordable, much less pushed by hype, and permit customers to kind reasonable expectations. Although many critics argue that fashions such because the Rainbow and S2F don’t have empirical grounding.
The framework might illuminate the trail, nevertheless it doesn’t essentially decide the vacation spot
To sum up, the 2 approaches present that Bitcoin maturation is approaching one other inflection, however reminders that arithmetic alone can’t seize all of the catalysts fueling the digital asset market. By incorporating liquidity change, regulatory attitudes and investor psychology, forecasts sharpen each prediction, permitting readers to deal with coloured bands and rarity ratios as information posts, moderately than iron-like units that keep belongings for technique.
Conversely, deviations from modeled paths can set off debate about knowledge integrity and encourage practitioners to mix conventional finance instruments with on-chain metrics earlier than enhancing their methodology or staking excessive stakes positions throughout the shift section.
