Bristlemoon September 2026 Quarterly Letter – Bristlemoon Capital

Bristlemoon Capital shorts Campbell's, arguing Walmart's rollout of 11,000 price cuts will squeeze food suppliers and margins.

Walmart delivered more than 11,000 price rollbacks in its latest quarter, up from 7,200 just three months earlier, and Walmart's CEO called it part of a plan to "invest heavily in price" and gain market share.

Bristlemoon Capital reads that jump as an early signal that Walmart is pushing harder on suppliers to fund its discounting, and has built a short position in The Campbell's Company around that view. Bristlemoon, which discloses a short position in Campbell's, frames the retailer as the "juggernaut of U.S. retail" whose pricing moves ripple through the rest of the grocery sector. The thesis sits inside a broader quarterly letter in which the fund reported a 34.8% loss over the prior twelve months.

Ticker: CPB (The Campbell's Company)
Research Firm: Bristlemoon Capital

Position Disclosure: Bristlemoon Global Fund holds a short position in The Campbell's Company (CPB), one of 19 disclosed short positions in the fund as of September 30, 2026.


Thesis

Bristlemoon Capital, which is short The Campbell's Company, argues that Walmart's expanding price-cutting campaign will tighten the squeeze on food suppliers.

  • Rollback Surge: Walmart delivered more than 11,000 price rollbacks in its Q2 2027 quarter, up from 7,200 at the end of the prior quarter, with CEO John Furner saying Walmart was "investing heavily in price" to gain market share and widen its price gap versus conventional grocers.
  • Supplier Squeeze Read-Through: Bristlemoon interprets the rollback expansion as evidence Walmart is "pushing back harder on suppliers" to fund its discounts, a long-standing Walmart practice, though it cites no separate source confirming tougher terms specific to this period.
  • Follow-the-Leader Pricing: The firm contends that because Walmart is the "juggernaut of U.S. retail," the broader retail market typically matches its pricing moves, spreading supplier pressure beyond Walmart's own shelves.
  • Pre-Existing Cost Inflation: Bristlemoon claims food suppliers were "virtually all" already contending with cost inflation before Walmart's pricing push intensified, without citing filings or named industry data.
  • Narrow Market Backdrop: Bristlemoon frames its short book against a market where the 10 largest S&P 500 stocks produced 70% of year-to-date index returns and nine of eleven sectors fell in September 2026, per data it attributes to Bloomberg.
  • Breadth Breakdown: The same Bloomberg-sourced data shows 83% of S&P 500 constituents traded more than 10% below their 52-week highs as of September 30, 2026, even as the index itself sat just 2% off its high.

Catalysts

  • Walmart's next quarterly earnings call: further growth in rollback counts or a wider price gap versus conventional grocers would reinforce the supplier-pressure thesis.
  • Campbell's upcoming quarterly filing: commentary on pricing, margins, or retailer negotiations would show whether Walmart's rollback push is translating into supplier concessions.
  • Competitor pricing moves: if rival retailers match Walmart's cuts, as Bristlemoon expects, pressure would extend to other food suppliers beyond Campbell's.
  • Rising yields and Iran-war-linked inflation: Bristlemoon says these pressures remain unpriced into certain of its short positions, a gap it expects markets to close.

Company Response

The report describes no request for comment to Campbell's and reports no response from the company to Bristlemoon's analysis.


Notable Details

  • The proportion of S&P 500 stocks with negative beta over a three-month window approached 45% by late 2026, a level Bristlemoon frames as unprecedented in the data series stretching back to 1990.
  • Bristlemoon said current AI models now produce analysis that surpasses a junior investment analyst's work "in a mere fraction of the time."
  • The fund says some firms are already using AI to run "swarms of expert calls" to gather non-public, on-the-ground information at a scale it had not previously seen.
  • Bristlemoon's fund lost 34.8% over the 12 months through September 2026, leaving its unit price at $0.779 despite running 99.2% long exposure and 72.5% net exposure.

"The days of sleuthing through an annual report and crunching the numbers to uncover insights that the market might have missed were already numbered before AI's recent advances."

Bristlemoon uses this line to argue that traditional, filing-based investment research no longer offers a durable edge.
