Robert Shiller on Meta
Same guidance shape, four months apart — the market shrugged once and punished it once, with nothing else in the fundamentals to explain the gap.
Shiller’s argument is that a market’s response to a piece of news depends less on the news than on which psychological anchor it happens to break — the same information can arrive twice and land twice as differently as it does (Irrational Exuberance). Meta’s 2026 capex guidance is close to a controlled version of that claim. In January, Meta guided full-year capex to $115–135 billion, above the Street’s $110.6 billion estimate and nearly double 2025’s $72.2 billion — and the market’s reaction went largely unremarked in the record (texxr.com/1162353). In April, on the same day Meta reported a record quarter — revenue up 33% to $56.31 billion, net income up 61% — it raised the range again, to $125–145 billion, and the stock fell more than 10% (texxr.com/1168007, texxr.com/1168006).
Nothing about the second number was uniquely worse than the first; both were increases on already-large figures, both arrived alongside strong underlying results. What changed, in Shiller’s account, is the anchor itself — a prior spending range holds until a second data point forces the market to read a pattern rather than a one-off, at which point the shift in sentiment is “rapid and discontinuous” rather than proportional to the new information (Irrational Exuberance). The January number could still be read as an ambitious plan. The April number, repeating the same shape three months later, read as a trend — the same “how much is already priced in” reversal Shiller’s new-era chapter describes at market peaks, just running on a single company’s guidance cycle instead of an entire market’s price-earnings ratio (Irrational Exuberance). Whether a third re-guide in Q3 or Q4 breaks the same way, or the market has now fully priced the pattern in, is the test the next print will run.
