On November 7, 2026, a post from Coin Bureau claimed that AI stocks had lost $13.2 trillion in market value from their 2026 highs, a figure relayed the same day by CryptoBriefing and Hokanews. We checked the six companies the post named against market data, company by company, from each one's 2026 high to the November 6 close. The verified total is about $5.3 trillion. The viral number is nearly two and a half times the real one, and it does not even match the post's own list of losses, which adds up to $5.95 trillion.
The ledger
| Company | 2026 peak | Nov 6 close | Verified loss | Claimed loss |
| Alphabet | $4.88T, May 13 | $3.50T | $1.38T, 28% | $1.62T, 32% |
| Nvidia | $5.88T, Oct | $4.52T | $1.36T, 23% | $1.49T, 25% |
| Broadcom | $2.35T, Jun | $1.40T | $0.96T, 41% | $0.97T, 41% |
| TSMC | $2.53T, Oct | $1.95T | $0.58T, 23% | $0.70T, 28% |
| Micron | $1.42T, Jun | $0.78T | $0.64T, 45% | $0.68T, 48% |
| Meta | $1.98T, Sep 24 | $1.56T | $0.42T, 21% | $0.50T, 25% |
| Total | $19.04T | $13.70T | $5.34T | $5.95T (parts); $13.2T (headline) |
Three ways the number fails
First, the parts do not add up to the headline. Add the six claimed losses together, $1.62 trillion for Alphabet, $1.49 trillion for Nvidia, $965 billion for Broadcom, $700 billion for TSMC, $678 billion for Micron and $501 billion for Meta, and the sum is $5.95 trillion. The headline claims $13.2 trillion, which is 2.2 times the sum of its own components. A number that disagrees with its own parts list by $7.25 trillion is not a rounding error. It is a number with no working behind it, and Coin Bureau published no working: no peak dates, no share counts, no as-of date beyond "through November 7," which was a Saturday, when markets were closed.
Second, the components themselves are overstated. All six claimed losses are higher than the verified loss. Broadcom is the closest, $965 billion claimed against $957 billion verified, a gap of $8 billion. The gap is largest at Alphabet. The claimed 32 percent decline and $1.62 trillion loss imply a peak market value of about $5.06 trillion. Alphabet's all-time high market capitalization is $4.88 trillion, set on May 13, 2026. The claimed figures describe a peak that never existed. Nvidia's claimed 25 percent implies a peak near $5.96 trillion; the verified peak, from the October price high of $243.37 times 24.147 billion shares, is $5.88 trillion. Meta's claimed 25 percent implies a peak of about $2.00 trillion; Meta's 2026 high is $1.98 trillion, set on September 24, and its all-time high is $1.99 trillion, set in August 2025. Every claimed percentage is at or above the verified one, and none of the six is understated. That pattern is what an inflated number looks like: the errors all point the same way.
Third, the comparison built on the number fails too. Coin Bureau's post said only the United States and China have annual GDPs larger than the $13.2 trillion erased. For the verified $5.34 trillion, that line no longer holds. The International Monetary Fund's October 2026 World Economic Outlook puts 2026 nominal GDP at $32.64 trillion for the United States, $21.55 trillion for China, and $5.47 trillion for Germany. Germany's economy is $0.13 trillion larger than the verified loss, so the "only America and China" framing depends entirely on the inflated figure. And the comparison itself needs a warning label, which Hokanews included: lost market value is not cash withdrawn by investors and not a decline in economic output. It is a repricing. A stock can lose a trillion dollars of market value while the company behind it keeps earning the same money.
How we checked
Market value is price times shares outstanding, so each company's peak is a price and a share count, and each closing value is the same multiplication on November 6. Peak prices come from Finnhub market data: Nvidia $243.37 in October 2026, Broadcom $495 in June 2026, TSMC American depositary receipts $487.47 in October 2026, and Micron $1,255 in June 2026. Alphabet's peak market value of $4.88 trillion on May 13, 2026 and Meta's 2026 peak of $1.98 trillion on September 24, 2026 come from Wall Street Numbers, which also gives the November 6 values of $3.50 trillion and $1.56 trillion; Finhacker corroborates Alphabet's $4.88 trillion all-time high. November 6 closing values for Nvidia ($4.52 trillion), Broadcom ($1.40 trillion) and Micron ($0.78 trillion) come from FinanceCharts. TSMC's November 6 value of $1.95 trillion is the closing ADR price of $375.44 times 5.186 billion ADR equivalents (25.93 billion ordinary shares at five per ADR), which matches FinanceCharts' $1.9 trillion. All arithmetic in the table is ByteHerald's, rounded to the nearest $10 billion in prose and shown to two decimals in the table. The as-of date is the November 6 close because November 7, 2026 was a Saturday. Two limits apply. Share counts move slightly with buybacks, so peak values computed from current share counts are estimates, good to about 1 percent. And vendors disagree by material amounts on individual names: published values for TSMC run from $1.59 trillion to $1.95 trillion depending on the vendor, the share count and the date, which is why the table shows the price-times-shares figure and names the method. Neither limit changes the verdict: even the most generous reading of the six companies, using the highest vendor figure for each, cannot reach $13.2 trillion, because their combined peak value was only $19.04 trillion and their combined November 6 value was $13.70 trillion.
What actually happened on November 5
The correction itself is real. The number is not. On November 5, two days after the United States midterm elections, the Nasdaq 100 fell 6.4 percent in a single session, its steepest one-day decline since March 2020, and roughly $2.3 to $2.5 trillion in value vanished from the index in that session, according to CryptoBriefing. The VIX, which tracks expected volatility in the S&P 500, jumped 70 percent the same day. Broader United States equities have lost about $5.7 trillion since an October 6 peak, according to CryptoBriefing. We covered that day on November 5, when the triggers were the Democratic midterm sweep, ballot measures limiting data-center construction, and doubts about whether AI spending will earn its return. CryptoBriefing's account of the cause matches: the trigger was not an earnings miss or a technical breakdown but the election, and specifically the fear that Democratic gains could bring tougher rules on data-center construction and AI development. That concern is a fear, not a law: no specific legislation is cited as the cause, and markets priced in the possibility of a stricter environment quickly. Underneath sits the older worry, which our November 3 ledger of $3.2 trillion in off-balance-sheet AI obligations documented: the buildout is increasingly paid for with debt and signed future commitments, so any doubt about returns hits valuations twice, once for the spending and once for the borrowing. The October 30 SaaS selloff showed the same doubt reaching software. A $5.3 trillion correction across six companies is already historic. It does not need $13.2 trillion to matter.
The test for the next viral number
Viral market numbers will keep arriving, and most of them will be wrong in the same four ways, so here is the test to run before sharing one. First, add up the parts. If the headline does not match its own list, stop there; no further checking is needed. Second, check the peak. A claimed percentage implies a peak value, and if that implied peak is above the company's all-time high, the numbers were invented, as Alphabet's were. Third, check the date. "From 2026 highs" to when: a Friday close, a midweek trough, or today? A loss measured to the worst day of the week is bigger than one measured to the close, and the choice is usually hidden. Fourth, ask what the basket is. Six named companies, the whole sector, or an undefined list? If the basket is undefined, the number cannot be verified at all, which is exactly the position Coin Bureau's $13.2 trillion is in: as a claim about the six named companies it is wrong by $7.9 trillion, and as a claim about some larger unnamed basket it is uncheckable. The honest version of this story is the ledger above, with dates, share counts, and a method anyone can repeat. That is the version worth citing.
