What Susan Athey and Robert Mitchnick actually calculated in June 2018 โ reconstructed from their published paper. Their result: $1.59 โ $8.23 per XRP, probability-weighted. No ETFs existed. No DTCC patent existed. Here's exactly how they got there.
โ ๏ธ This Was Written Before Any of This Existed
In June 2018, none of the following existed: spot XRP ETFs (first approved 2025), the DTCC patent naming XRP/XLM (filed 2025), RLUSD (launched Dec 2024), Hidden Road acquisition by Ripple (2025), or the CLARITY Act. Athey and Mitchnick built their model purely from XRP's cross-border payment use case and SWIFT-replacement thesis โ using transaction volume data from 2017โ2018 ODL pilots, not institutional custody data. This calculator reconstructs exactly what they had access to.

๐ The Exact Formula From the Paper
D = Yt + I (Total Demand = Transaction Demand + Storage Demand)
S = (N + ฮณ) / ฯ (Total Supply, incl. future issuance + lockups, รท reserve ratio)
v = ฯ(Yt + I) / (N + ฮณ) (Fundamental Value per Unit)
P = v ร (1 + i)โปแต (Present Value, discounted)
Where Y = daily transaction volume, t = average hold time between transactions (days), I = storage/store-of-value demand, N = current supply, ฮณ = future issuance or locked supply, ฯ = "fractional reserve ratio" (a key concept absent from most later XRP calculators).
XRP "Success Case" โ As Defined in the Paper (Section 3.2)
Athey/Mitchnick defined the XRP Success Case as: "a state of the world in which XRP is adopted as part of a widely-used cross-border payments standard, and in which XRP is adopted for use by financial institutions, corporations, and individuals to effect FX transactions."
25% probability assigned to this Success Case
75% probability assigned to Failure Case, broken down as:
Failure Mode
Probability
Description
No crypto adoption
30%
Cross-border crypto never gains meaningful adoption, or governments build alternatives instead
SWIFT defends position
20%
SWIFT consortium innovates and successfully defends its incumbent position
Fragmented competitors
15%
A scattered set of alternative networks emerge instead of one winner
Other failure modes
10%+

๐ What's Changed Since June 2018
The model's structure hasn't changed. But nearly every input variable has โ which is exactly why a second, updated calculator is needed rather than just re-reading the same numbers.
โ New Since 2018
7 US spot XRP ETFs (923.7M XRP locked) ยท DTCC Patent naming XRP+XLM ยท RLUSD stablecoin ($1.7B+) ยท Hidden Road acquired by Ripple ยท BIS mBridge ยท CLARITY Act progress
โ ๏ธ Reduces Effective Supply
ETF lockup + long-term holders + DeFi protocols absorb far more supply than the paper's simple "ฯ reserve ratio" anticipated in 2018 โ before any of these existed
๐ New Demand Sources
DTCC $4.7Q annual volume ยท $846T derivatives market context ยท 130+ CBDC programs ยท None of these were modeled in 2018 โ XRP was purely a SWIFT-replacement thesis then
โ Still Unresolved
SWIFT has not been displaced. Most banks still use correspondent banking. The "Failure Case" probabilities from 2018 may still apply in part โ adoption remains the open question
Susan Athey โ "The Future of Currency" โ Stanford GSB, October 2018 ยท Recorded roughly four months after the valuation paper was published. Key moment: when asked directly about competing cryptocurrencies, Athey explains why she believes there is no "one size fits all" winner โ and specifically describes why Ripple abandoned a pure-cryptocurrency pitch to banks after they pushed back on regulatory risk. "A lot of banks said: we love this idea, could you do this for us but without the cryptocurrency?" This is the most important nuance missing from most retail XRP discourse: Ripple's own banking partners, as late as 2018, often wanted the ledger technology without XRP itself.
๐๏ธ The Most Important Quote From This Talk
"The interesting thing that happened with Ripple is that they went out and tried to sell this to banks... and some banks were interested, but actually a lot of banks said, hey, we're a little worried about this cryptocurrency thing, it's got regulatory risks... so could you do this for us but without the cryptocurrency? [...] So Ripple introduced something called an interledger protocol... it's a protocol that basically will say, if I want to get money from one into the other, there might be a bunch of middlemen, market makers... and we're going to have a protocol that ensures the money instantly goes from A to B, but it never gets stuck in the middle."
โ Susan Athey, Stanford GSB, October 2018
This directly explains the tension in today's debate: was XRP ever meant to be the only path? No โ Athey describes how, even in 2018, many banks adopted Ripple's underlying ledger and routing technology (which became Interledger Protocol) without ever touching XRP. The bridge-currency use case for XRP specifically depends on banks choosing to use it for FX conversion โ not merely using Ripple's software.
This is also the talk where she discusses XRP's transaction volume directly: "Ripple... we were having lots of $4 billion days... and then more recently it's been about a half a billion dollars a day." โ giving us the actual 2018 volume data the original valuation model would have used for the Y (transaction volume) parameter.
Step 2 of 2
Now See the Same Formula With 2026 Data
ETFs exist now. The DTCC patent exists now. RLUSD exists now. Use the same Athey/Mitchnick formula โ but with the institutional infrastructure that has been built since this paper was written.
