Anthropic's $64bn IPO is pricing into a 5% Treasury yield. Its valuation is taking the hit.

Anthropic put a price on itself on Tuesday: $70 to $78 a share for 825mn Class A shares, a raise of up to $64bn that would rank among the largest initial public offerings on record. Within hours, the Labor Department reported that consumer prices rose 0.4% in October, more than expected, and the 10-year Treasury yield climbed 14 basis points to 5%.

Those two facts belong together. A company valued at as much as $1.4tn on a fully diluted basis, against a run-rate revenue of about $81bn and a $104bn net loss for the first nine months of the year, is being priced almost entirely on profits it expects to earn years from now. The higher the rate at which investors discount those profits, the less they are worth now.

Traders have drawn the same conclusion. As of the evening of 10 November, they put the chance that Anthropic's market value closes its first day of trading below $1.5tn at 65%. A week earlier, it was about one in five.

A price range that already gave ground

The terms Anthropic set out are themselves a retreat. The company is selling 801mn new shares, with existing holders selling 23.6mn, and has applied to list on Nasdaq as "ANT". People familiar with the deal told CNBC that pricing is planned for 18 November, with trading to start the next day.

On the roughly 13bn shares outstanding after the offering, the range values Anthropic at roughly $1tn. Counting all shares on a fully diluted basis, the top of the range is $1.405tn, and the midpoint works out at roughly $1.33tn. Until recently, Anthropic had been looking toward $2tn; shareholders told CNBC that even $1.5tn was now in doubt, with one calling it a "stretch".

"What we are seeing is essentially a reassessment of Anthropic's value in a more challenging AI environment," Ipek Ozkardeskaya, a senior analyst at Swissquote Bank, told Reuters.

The rate shock arrived on roadshow day

October's inflation report did the damage. Core prices rose 0.3%, against forecasts of 0.2%, and the two-year yield jumped 19 basis points to 4.74%. Fed governor Christopher Waller said a half-point rise "should be considered" at the December meeting, adding that "hiking only 25 basis points would put our credibility at risk". Futures fully price a quarter-point December rise.

What matters for Anthropic is how long rates stay high. Traders now give about 50% to a further quarter-point Fed rise in January, up 32 points in a day. They put the chance of the 10-year yield falling below 4.7% before the end of this year at only 31%, down 17 points.

The arithmetic is unforgiving for companies whose value lies far in the future. A business expected to generate most of its cash in the 2030s loses proportionally more value from each extra point on the discount rate than one paying dividends now. At about 17 times annualised revenue at the top of the range, and with close to $900bn of computing commitments, Anthropic sits at the long end of that spectrum.

Where traders think the first day ends

Traders give 41% to a first-day closing value between $1.25tn and $1.5tn, up 12 points, and 24% to one below $1.25tn, up 10 points. The chance of $1.5tn to $1.75tn fell 10 points to 22%, and $1.75tn to $2tn dropped to 6.6% from 30% a week ago.

The centre of expectations, $1.25tn to $1.5tn, roughly matches the fully diluted value of the price range itself, about $1.26tn to $1.4tn. Traders are no longer counting on the first-day surge that would carry the company well past $1.5tn.

None of this casts doubt on the listing itself. Traders put the chance of an IPO by 30 November at 96%, and by 20 November at 91%, both up sharply as the roadshow confirmed the timetable. The question is price, not whether.

The broader AI trade is moving the same way. Traders now give Apple an 82% chance of being the world's largest company at the end of December, against 35% a week ago; Nvidia's has fallen to 16% from about 65%.

Why the first day could still surprise

The case for a stronger debut is real. People familiar with the deal told CNBC the offering was already fully subscribed across the range, with institutional demand stronger than for SpaceX at the same stage. Seven companies, including Google, Nvidia, Microsoft and AMD, have agreed to buy $26bn of non-voting stock at the IPO price. Nine-month revenue rose roughly 1,200%, and most of the net loss reflects non-cash changes in the value of convertible notes. A planned retail allocation of about 20%, well above the usual 5-10%, could add first-day buying.

For traders to be wrong on the downside, a cooler inflation reading or softer Fed rhetoric before 18 November would need to pull yields back, or demand would need to force the price above the range. Eight days leaves little time for the first, but strong early demand makes the second possible.

Anthropic will almost certainly list this month. The bond market has already decided it will cost less than its backers once hoped.
