Jesse Eckel says lab-grown gold could strengthen Bitcoin's scarcity edge

In short

• On 21 October 2026, Marathon Fusion said it turned mercury into real, stable gold, beating CERN's record by a factor of 10.
• Analyst Jesse Eckel said lab-grown gold could become cheap like synthetic diamonds, while Bitcoin's supply stays capped at about 21 million coins.
• Eckel argued artificial gold could weaken gold's scarcity and strengthen Bitcoin's long-term scarcity edge, according to U.Today and TradingView.
• Reactions on X ranged from scepticism about radioactivity and cost to warnings that gold is not yet in trouble.

Marathon Fusion's mercury-to-gold claim

Marathon Fusion, a San Francisco startup, announced on 21 October 2026 what it called 'high-rate alchemy: turning mercury into real, stable gold, beating CERN's record by a factor of 10', in a post seen by InvestIn.News. Jesse Eckel, a US market analyst, then argued that lab-made gold might eventually cost little, as synthetic diamonds do, leaving Bitcoin's capped supply the stronger of the two, according to U.Today and TradingView. At 11:14 UTC on 22 October 2026, Bitcoin (BTC) traded at $81,945, down 1.71% in 24 hours, with a market value of $1.65tn, according to InvestIn.News market data.

Marathon Fusion is a San Francisco startup that in 2025 outlined a process to produce roughly 5,000 kilograms of gold a year from a gigawatt-scale fusion power plant, using high-energy neutrons to turn a specific mercury isotope into gold through nuclear transmutation, according to TradingView. The company says it is now building a fusion reactor in San Francisco to achieve record power density, but its latest experimental claims do not establish that artificial gold can be produced cheaply or at industrial scale.

Eckel's synthetic diamond comparison

Eckel's argument leans on a parallel with synthetic diamonds. He wrote on X on 21 October: 'The reality is lab grown gold will eventually happen and be cheap just like diamonds' and 'There will never be lab grown $BTC', according to TradingView. If technological progress weakens gold's scarcity, he said, Bitcoin's mathematical supply cap would stand out, CoinNess reported. KuCoin and Bitbase also covered the analyst's comments.

Why Bitcoin's 21 million cap matters

For ordinary savers who compare gold and Bitcoin as stores of value, the difference is supply. Gold can increase through mining discoveries, technological improvements and potentially nuclear transmutation, while Bitcoin has a maximum supply of about 21 million coins, according to TradingView. Bitcoin's issuance follows a set schedule, with mining rewards halving roughly every four years, and changing the cap would require altering the network's consensus rules. Eckel's point is that if artificial gold ever grows supply, gold may behave more like a commodity, while Bitcoin's scarcity stays written in its code.

Scepticism on X about cost and radioactivity

On X, respicepostte (@respicepostte1) said gold bugs would be upset when they read about this in a newspaper in a month. Axonera (@axonera_ceo) said the gold would be radioactive for 14 years and cost close to the current price. Graham (@Shenanigrahams) said Peter Schiff's thesis was under attack, while trading_axe (@trading_axe) argued that alchemy was never a meme, pointing to the diamond chart for gold's future. RAB-SWFL (@RABSWFL) said gold is not in trouble: beating CERN by a factor of 10 is still an intangible amount.

The fusion reactor still to be built

Marathon Fusion says it is now building a fusion reactor in San Francisco to achieve record power density, according to TradingView. The startup's latest experimental claims do not show that artificial gold can already be made cheaply or at industrial scale, and TradingView noted that commercial production remains a distant prospect. Eckel's argument is therefore about the long-term direction of gold supply rather than a near-term change in the market.

Questions readers ask

Can Bitcoin eventually replace gold as currency?

This report does not say Bitcoin will replace gold as a currency. Analyst Jesse Eckel argues that if artificial gold increases gold's supply, gold may look less scarce and Bitcoin's fixed 21 million coin cap may become more valuable, according to U.Today and TradingView.

How did Marathon Fusion claim to make gold?

Marathon Fusion said it used high-energy neutrons to convert a mercury isotope into real, stable gold through nuclear transmutation, and that it beat CERN's record by a factor of 10, according to TradingView. The startup has not shown cheap industrial-scale production.

Why is Bitcoin's supply capped at 21 million?

Bitcoin's code sets a maximum supply of about 21 million coins, with mining rewards halving roughly every four years. Increasing that limit would require changing the network's consensus rules, according to TradingView, so its scarcity is mathematically fixed rather than dependent on production.

Our view

At InvestIn.News, we think Eckel's argument is sound but conditional. If artificial gold actually increases gold's supply on a meaningful scale, people may come to see gold as an ordinary commodity rather than a scarce store of value. In that scenario, Bitcoin's mathematically fixed supply of about 21 million coins would look more durable.

We consider Bitcoin's scarcity easier to verify than gold's. New gold could come from mining, new discoveries or, in theory, nuclear transmutation, while Bitcoin's cap is written into its code and cannot be raised without changing its consensus rules. That is a structural difference, not just a price story.

The present claims from Marathon Fusion do not yet show cheap industrial-scale production. A demonstration of artificial gold at low cost and meaningful scale would confirm the view that gold's scarcity is weaker than Bitcoin's.
