Fusion week: Marathon Fusion's mercury-to-gold claim drew the pushback, while American Fusion's Texatron updates ran in parallel

Who was talking, day by day
What happened
@marathonfusion said it demonstrated high-rate alchemy turning mercury into real, stable gold, beating CERN's record by a factor of 10, and enriched isotopes in the world's most powerful plasma centrifuge, beating a 40-year-old Soviet record. @pdmytriiev argued that selling gold because of fusion alchemy front-runs a reactor that doesn't exist, using mercury costing 100,000x more than the gold it makes, and stated yields of 2–5 tonnes per gigawatt plant per year against 3,500–4,000 tonnes of annual mine supply.
+ 8 more in the evidence register ↓Why it matters
The fusion phrase trended for one week and then faded, driven by two unrelated uses of the word rather than a single sustained story.
Observed reaction
The gold-from-mercury thread dominated engagement, with pushback rather than enthusiasm: @pdmytriiev argued selling gold on it is front-running a reactor that doesn't exist, @bitcoinbombadil questioned "free energy" economics, and @trollstein and @iwantlambo treated it as one more alarming headline alongside AI agents in bank accounts. The $AMFN posts were promotional in tone.

Evidence register
@pdmytriiev argued that selling gold because of fusion alchemy front-runs a reactor that doesn't exist, using mercury costing 100,000x more than the gold it makes, and stated yields of 2–5 tonnes per gigawatt plant per year against 3,500–4,000 tonnes of annual mine supply.
[1]@pdmytriiev stated enriched mercury-198 sells for about $15,000 per milligram versus gold near $135 per gram, and that the gold would need 14–18 years of storage.
[1]@trollstein listed a fusion startup claiming it made gold from mercury as the first item in its past-24-hours roundup, alongside major banks reporting AI agents accessing customer accounts.
[1]@iwantlambo asked whether quantum computers cracking bitcoin or fusion turning mercury into gold is the bigger issue.
[1]@bitcoinbombadil said it has trouble with the idea of 'free energy' even in a world of fusion energy, arguing prices adjust and there is no free lunch.
[1]@deexra posted that American Fusion ($AMFN) announced an operational and commercial expansion for its Texatron fusion platform: four new Texas data center proposals under a Power-as-a-Service model, an occupancy permit for a new HQ/research facility, a planned North Texas research campus and investment banking negotiations.
[1][2]@icplegend1966 posted Internet Computer network metrics: 35.665 billion metered WebAssembly instructions per second, 5,991.71 transactions per second, 164.57 blocks finalized per second, 1,168,387 canister smart contracts and 3,307,008 Internet Identities as of 18 October 2026; and later 42 mainnet subnets across 33 countries, 618 node machines, 72 node providers, 92 data centres and over one million canister smart contracts.
[1][2]@darklord_gr said Bitcoin-backed USDC borrowing on @Morpho Base markets hit a record of about $1.6B outstanding, mostly through Coinbase's variable rate product using cbBTC collateral, with Spark supplying over $400M USDC into the cbBTC/USDC market on Base.
[1]@mjahangirifard commented that a hero fusion mechanic adds an interesting progression loop and that combining rarity upgrades with different skills could make team building more strategic.

- Explainer: why Marathon Fusion's mercury-198 route to gold is real physics but not a gold-supply event, using @pdmytriiev's yield and cost figures.
- Reaction roundup: how CT treated the fusion-gold claim as one of several alarming headlines this week, alongside AI agents in bank accounts and the $81k BTC print.
- Separate thread: American Fusion ($AMFN) Texatron commercialization updates and four Texas data center proposals, flagged as promotional.

Risks
- Marathon Fusion's mercury-to-gold and centrifuge claims are company claims quoted by @marathonfusion and relayed by @pdmytriiev; they are unverified outside the company's own posts.
- The @pdmytriiev cost, yield and storage figures are his own analysis, not market data.
- $AMFN posts by @deexra read as promotional expansion updates for a company with a ticker; treat as likely paid or coordinated promotion.

If you’re selling gold because of fusion alchemy, you’re front-running a reactor that doesn’t exist, fed with mercury that costs 100,000x more than the gold it makes, to produce bars you couldn’t legally sell for 15 years. Marathon Fusion’s idea is real physics, since fusion neuOpen on X →
