Is Bitcoin Undervalued? Elon Musk's Energy Money Vision and What Hashrate Data Says About BTC's Fair Value

Elon Musk just described Bitcoin without saying its name. In a podcast interview released on October 20, 2026, the world's richest person told his biographer Walter Isaacson that the money of the future will not be measured in dollars — it will be measured in watts, tons, and joules. Bitcoin, an asset whose entire existence is anchored to electricity, suddenly looks less like a speculative trade and more like an early prototype of exactly what Musk is describing. And according to one widely followed valuation model, it is trading at a steep discount to that idea.

This article breaks down what Musk actually said, why crypto analysts heard "Bitcoin" in every word, what the energy-based valuation math really shows, where the argument falls short, and what it means for BTC investors watching the $84,000 level.

What Elon Musk Actually Said About Energy Money

Musk's remarks came during an appearance on The Builders podcast with his biographer Walter Isaacson. The interview was recorded in early August but only published on October 20 — and it quickly went viral across crypto circles.

Musk argued that advances in artificial intelligence and robotics will eventually make human labor far less relevant, and that conventional money will lose its meaning in the process. But he stopped short of predicting the end of currency itself. Instead, he predicted its transformation:

"There will be still a currency, but I think currency will be measured in fundamental physics metrics like, power, like wattage and tonnage, mass and energy… conventional currency will not matter in the future."

In a separate clip that circulated on X, he put it even more bluntly: "Currency will be measured in mass, power and energy. Conventional currency will not matter. It's pretty obvious."

The idea is not entirely new for Musk. Back in June, he had already written on X that mass and energy would eventually take the place of dollars. The prediction carries extra weight because of who is making it — Business Insider reported that the Bloomberg Billionaires Index put Musk's net worth at roughly $920 billion, making him the richest person on the planet.

Crucially, Musk never mentioned Bitcoin in the interview. Not once. The crypto connection came from analysts who responded within hours — a detailed breakdown of Musk's energy-money remarks shows how quickly the Bitcoin community claimed the narrative.

Why Everyone Heard "Bitcoin" Even Though He Never Said It

Money anchored to energy describes the one property that proof-of-work already builds into Bitcoin. Unlike fiat currency, which a government can create with a keystroke, every new bitcoin must be "mined" by computers performing real, measurable work — burning electricity to solve cryptographic puzzles and secure the network.

Charles Edwards, founder of Capriole Investments, responded to Musk's remarks within hours, arguing that Bitcoin already operates according to an energy-based monetary concept. Edwards considers the relationship between energy and price to be one-to-one: the more energy the network consumes, the more "money" each bitcoin represents.

The resonance goes deeper than the podcast. Responding to a post by market commentator ZeroHedge about the global AI arms race, Musk previously stated: "Bitcoin is based on energy: you can issue fake fiat currency, and every government in history has done so, but it is impossible to fake energy." ZeroHedge had framed the AI race as a debasement story — governments in the U.S. and China will fund massive AI capital expenditure, which inevitably debases currencies — and concluded, "you can't print energy."

That logic ties into the growing macro conversation around energy, scarcity, and the digital economy. As AI data centers devour unprecedented amounts of power, the question of what constitutes "real" value is shifting. For Musk, Bitcoin represents a model of what cannot be artificially expanded — a system where energy expenditure equals trust.

It is worth noting that Musk has historically been cautious about making strong public statements on Bitcoin. His latest remarks suggest a renewed conviction in its fundamental value, especially as governments expand spending to fund technological competition. Tesla itself remains a major corporate holder, with its Q3 2026 earnings showing 11,509 BTC on the balance sheet — roughly $2.5 billion worth at current prices when combined with SpaceX's stack.

The Energy Value Model: Pricing Bitcoin in Joules

The valuation framework Edwards invokes is the Bitcoin Energy Value model, first laid out in his 2019 paper. It calculates a fair value for BTC using only physical inputs: the electricity consumed by miners, expressed through network hashrate, mining hardware efficiency, supply growth, and a constant measured in dollars per joule. An analysis of Capriole's Energy Value estimate puts the current fair value near $131,057, roughly 36% above the market price.

The model is disarmingly simple in concept. If Bitcoin is energy money, then its fair value should track the energy embodied in the network. When price runs far above the line, the market is paying a speculative premium. When it trades below the line, buyers are getting the embodied energy at a discount — and historically, price has tended to return toward the line over time.

That history is what makes the model worth watching:

• Speculative peaks came with premiums: BTC traded well above its Energy Value near the 2013, 2017, and 2021 cycle tops, when retail mania pushed price beyond anything the network's energy footprint justified.
• Bear-market bottoms came with discounts: Readings below the line lined up with the 2015, 2018, 2020, and 2022 lows — the moments of maximum fear that turned out to be the best buying opportunities.
• This cycle broke the pattern: BTC tracked the Energy Value line through 2024 and 2025 without ever developing the big speculative premium seen at previous tops. In other words, this cycle never overheated relative to the energy in the network.

That last point is the bull case hiding inside the model. If every previous cycle eventually pushed price above Energy Value — and this one hasn't — the missing premium is, arguably, still to come.

What the Numbers Say Today: $83,000 Price vs $131,000 Energy Value

Capriole's current Energy Value estimate puts Bitcoin's fair value at approximately $131,057 to $137,000, depending on the exact reading used. With BTC trading near $83,000–$84,400, that implies:

• Discount to energy value: roughly 36% to 38.5% below the model's fair value.
• Upside to reach the line: a gain of about 57% to 63% from current levels.
• Independent confirmation: JPMorgan's recent estimate of Bitcoin's production cost sits near $85,000 — just above today's price — meaning miners, on average, are producing bitcoin at roughly what the market will pay for it.

Put differently, buyers today are acquiring the network's embodied energy at a deeper discount than at any point since the 2022 bear-market lows — and without the speculative excess that marked previous tops.

That does not make the Energy Value a price target on a calendar. The model describes a gravitational center, not a date. Price can trade below it for months, as it has through much of 2026. But for long-horizon investors asking whether Bitcoin is "cheap" or "expensive," the model offers an answer grounded in physics rather than sentiment: cheap, by its own measure.

It is also instructive to compare this with the other big institutional valuation now in the headlines. JPMorgan Asset Management's first-ever long-term Bitcoin forecast projects 10% annualized returns over a decade — and JPMorgan's three Bitcoin scenarios for 2036 put the bull case as high as $386,000 against a $25,000 bear case. Two very different methods — one rooted in energy, one in macro finance — both pointing above today's price.

Hashrate at 1 ZH/s: The Network's Energy Meter Keeps Climbing

The most striking part of the energy-money story is not the price at all. It is the network behind it. Blockchain.com data shows Bitcoin's hashrate — the computing power securing the network — topping 1.1 zettahashes per second (ZH/s) in October 2025, dipping toward 900 exahashes per second under pressure on miners, and climbing back above 1 ZH/s in October 2026.

Meanwhile, price nearly halved from its October 2025 record before building a floor near $60,000 in June 2026. The energy behind the network barely moved while its dollar price swung wildly. That divergence is the entire thesis in one chart: the network's energy commitment is sticky and structural, while the price is emotional and cyclical.

The stickiness showed up again this month: Bitcoin's mining difficulty hit a record 140.58 trillion as hashrate reclaimed the 1 ZH/s level. The full hashrate and valuation data behind the debate shows miners kept the power on through the drawdown — difficulty adjusts every two weeks to keep blocks arriving every ten minutes, and a new record means more miners are competing for the same block reward than ever before, even at current prices. Miners do not keep the power on out of optimism — they do it because the economics still work.

This is also why the "you can't fake energy" line resonates. Hashrate cannot be printed, faked, or conjured by a central bank. It represents real-world computation, real electricity bills, and real hardware — a physical cost basis that no fiat issuer can replicate.

The Irony: Musk Attacked Bitcoin's Energy Use in 2021

There is a delicious irony in Musk now framing energy as money's future virtue. In May 2021, Tesla suspended Bitcoin payments for its cars, citing the fossil fuels burned in Bitcoin mining. Musk's criticism helped trigger one of the nastiest sell-offs in crypto history.

Five years later, the debate has flipped completely. The energy use Musk once cited against Bitcoin is now the very property that ties it closest to his vision of future money. By his own measure — money measured in wattage and joules — Bitcoin resembles future money more than the dollar does.

To be fair, the network Musk criticized in 2021 is not the network of today. The post-China mining-ban era pushed miners toward stranded hydroelectric power, flared-gas capture, and increasingly renewable-heavy mixes in the U.S. and elsewhere. Whether that fully answers the environmental critique is debatable — but it is no longer the coal-heavy network of 2021.

The market, notably, has not priced in Musk's endorsement. Bitcoin's reaction to the podcast was subdued, trading in the low $80,000s. That may be the most telling detail of all: the "Musk effect" of 2021 — when a single tweet could move the market 20% — has faded. Today's market wants data, not vibes.

Where the Energy-Money Argument Falls Short

A good thesis needs its strongest objections stated plainly. Here are the ones that matter:

• Bitcoin answers only half of Musk's formula. Proof-of-work ties Bitcoin to energy, but nothing ties it to mass. Musk mentioned wattage, tonnage, and mass together — Bitcoin covers the energy leg, not the rest.
• Hashrate is a proxy, not a power meter. Newer mining machines extract more hashes per watt than older ones, so rising hashrate does not translate one-for-one into rising electricity consumption. The model's dollars-per-joule constant needs constant recalibration.
• Musk may mean energy itself as the unit of account. He may be imagining a world where kilowatt-hours are the currency — no token, no blockchain, just energy credits. In that reading, Bitcoin is an analogy, not the answer.
• Unlike scarcity models, Energy Value can fall to zero. If every miner switched off, the model says Bitcoin is worth nothing. Stock-to-flow and similar models make no such concession. The energy anchor is real, but it is conditional on the network surviving.
• Energy cost is a floor, not a magnet. Production-cost models famously failed in 2018 and 2022, when BTC traded below miner break-even for extended stretches. Miners capitulating can push price down toward the line — not always bounce off it.

None of these invalidate the framework. But they explain why professional investors treat Energy Value as one input among many — alongside on-chain data, ETF flows, and macro conditions like the October 31 price outlook and the Fed's rate decision — rather than a standalone buy signal.

What Would It Take for Bitcoin to Reach Energy Value?

Closing a 36% discount to Energy Value requires roughly a 57% rally — from ~$83,000 to ~$131,000. That is not a prediction, but it is worth mapping what would need to happen:

• A macro all-clear: The October 28 Fed decision is the near-term gate. A dovish signal would weaken the dollar and lift risk assets; a hawkish surprise would do the opposite. Rate expectations remain the single biggest driver of BTC's price over weeks, not years.
• ETF flows turning positive: U.S. spot Bitcoin ETFs have seen choppy flows through October. Sustained inflows would provide the marginal buying pressure a 57% move requires — no rally of that size happens without institutional-sized bids.
• The speculative premium returning: This cycle's defining oddity is the missing mania. Previous Energy Value overshoots came with retail frenzies. A return of broad risk appetite — the "Greed" phase of the cycle — is historically what carries price above the line.
• Time: Mean reversion to Energy Value has historically taken months, not days. The model rewards patience, not leverage.

Conversely, the discount could widen. If miners face another profitability squeeze and hashrate rolls over, the Energy Value line itself would fall — the model is dynamic, and fair value drops when the network's energy commitment drops.

What Traders and Investors Should Watch Next

For readers deciding what to do with this information, three practical takeaways stand out:

• Watch hashrate, not just price. Price tells you what the crowd feels; hashrate tells you what the network costs. As long as hashrate holds above 1 ZH/s and difficulty keeps printing records, the energy floor under Bitcoin is intact.
• Watch the miner break-even zone. With JPMorgan's production-cost estimate near $85,000 and BTC trading just below it, miners are operating at roughly zero margin on average. Extended trading below cost has historically preceded miner capitulation — and capitulation bottoms.
• Treat Musk as a thesis, not a signal. The 2021 Musk premium is gone. What remains is the idea, and ideas compound slower than tweets. Energy money is a decade-scale argument; position sizing should reflect that.

Frequently Asked Questions

What did Elon Musk say about Bitcoin and energy?

Musk never mentioned Bitcoin by name in the October 20 Builders podcast. He said future currency will be measured in "wattage and tonnage, mass and energy" rather than dollars. Analysts connected the remarks to Bitcoin because proof-of-work makes BTC the only major asset whose value is anchored to real energy expenditure.

What is Bitcoin's Energy Value?

It is a valuation model developed by Capriole Investments' Charles Edwards that estimates Bitcoin's fair value from the electricity miners consume — using network hashrate, hardware efficiency, supply growth, and a dollars-per-joule constant. The current estimate sits near $131,000–$137,000, about 36–38% above BTC's market price.

Is Bitcoin undervalued right now?

By the Energy Value model's measure, yes — BTC trades roughly 36% below the model's fair value, a deeper discount than at any point since the 2022 bear-market lows. JPMorgan's production-cost estimate near $85,000 also sits just above the current price. No model guarantees future returns, and price can remain below fair value for extended periods.

Why didn't Bitcoin's price rally on Musk's comments?

The market reaction was muted, with BTC holding in the low $80,000s. The "Musk effect" of 2021 — when tweets moved the market dramatically — has faded. Today's Bitcoin market is dominated by ETF flows and macro data like Fed rate decisions, which carry more weight than any single endorsement.

Can Bitcoin's Energy Value go down?

Yes. The model is dynamic: if miners shut down and hashrate falls, the Energy Value line falls with it. Unlike scarcity-based models, it would read zero if the entire network went offline. The energy anchor is real but conditional on miners keeping the network running.

How does the Energy Value model compare to JPMorgan's Bitcoin forecast?

They use completely different methods. JPMorgan's Long-Term Capital Market Assumptions project 10% annualized returns over a decade (~$215,000 by 2036 in the base case). The Energy Value model is physics-based, pricing BTC from mining energy inputs. Both currently point to upside from today's ~$83,000, but on very different time horizons.

Conclusion

Elon Musk set out to describe the money of the future and accidentally wrote Bitcoin's investment thesis. Whether or not he intended it, the logic is hard to dismiss: in a world where AI makes labor abundant and governments print money to fund it, the one monetary property that cannot be faked is energy expenditure — and Bitcoin is the purest expression of energy converted into money that exists today.

The data backs the poetry, at least partially. Hashrate above 1 zettahash per second, mining difficulty at an all-time high, and an Energy Value model reading 36% above the market price all say the same thing: the network's energy commitment has never been stronger, while its price has never been cheaper relative to that commitment in this cycle.

But the objections deserve the last word. Energy is a cost, not a destiny. Hashrate can fall, miners can capitulate, and Musk himself may have meant kilowatt-hours as the currency — not a token at all. Treat the energy-money thesis as a valuation lens, not a prophecy. In a market driven week to week by ETF flows and Fed decisions, the wattage argument is a reason to think in years, not days.
