Peter Thiel is betting big on AI-powered cow collars — and Canadian investors should be paying attention

For Canadian investors, the story is more than just a quirky tech headline — it's a signal about where serious capital is flowing in the agriculture sector, at a time when Canadian beef prices are at record highs and ranchers here at home are searching for ways to do more with less.

What Halter actually does

Halter's solar-powered collars use AI to create virtual fences for cattle, eliminating the need for physical barriers. The collars connect to a farmer's phone, allowing producers to monitor their herd's location and health indicators through an app — and even move cattle remotely using vibrations and audio cues from the devices.

It's a step beyond the typical livestock monitoring collar, which typically focuses on tracking digestion or breeding cycles. Halter's pitch: full herd management from a smartphone, at US$5 to US$8 (C$7 to C$11) per animal per month.

"The goal was to make pasture farming more sustainable and productive using technology,” Halter founder Craig Piggott told to Bloomberg in 2024.

The company's last funding round pulled in US$100 million (C$140 million) at a roughly US$1 billion valuation in June, led by BOND. Halter has since set up a Colorado office and said it's prioritizing expansion in the U.S.

Why Canadian farmers should be watching

Canada's cattle industry is at an inflection point. The national herd fell for three consecutive years before posting a modest 0.8% recovery in July 2025, when Statistics Canada counted 11.9 million cattle and calves — still among the lowest levels recorded since the 1980s (2).

Drought in western Canada, rising feed and labour costs, and an aging farming population have all squeezed producers. Meanwhile, retail prices for Canadian beef climbed 16% in 2025, according to research from Dalhousie University — and are expected to remain elevated into 2026 and 2027 (3).

Against that backdrop, technology that promises to cut labour costs and help producers do more with fewer workers has obvious appeal. Farm Credit Canada (FCC), an Ottawa-based federal Crown corporation that provides financial services to Canada's agricultural sector, committed US$2 billion through 2030 to accelerate agtech innovation (4).

Precision agtech outlier in a struggling sector

Halter's momentum is notable because agtech has had a rough few years globally. A wave of agricultural technology startups have declared bankruptcy, and venture capital firms are largely pulling back from the sector as companies struggle to convince farmers to adopt their products amid high operational costs.

But precision agriculture — the broader push to use technology to manage farms more efficiently and reduce labour needs — remains a fast-growing market. Industry estimates peg the global precision agriculture market at roughly US$9.5 billion in 2025, with projections to surpass US$17 billion by 2031 (5).

Closer to home, the Canadian precision farming market generated US$1.5 billion in 2023 and is projected to reach US$3.7 billion by 2030, growing at a compound annual growth rate (CAGR) of 13.4%, according to Grand View Research (6). Canada accounted for 14.6% of the global precision farming market in 2023.

More efficient farming could eventually translate to more stable food prices for consumers, though that connection is still playing out.

How Canadian investors can get exposure

Halter is private, so you can't buy shares directly. But several publicly traded companies are already deep in the precision agriculture space — and could benefit as the same tailwinds lift the sector.

For Canadian investors, the most direct domestic play is Nutrien Ltd. (TSX/NYSE: NTR), headquartered in Saskatoon, SK. Nutrien is the world's largest producer of potash and a major provider of crop inputs and services. Its Nutrien Ag Solutions division operates one of the largest precision agriculture retail networks in North America, providing soil testing, GPS-guided crop scouting, data analytics and agronomic planning tools to over 500,000 growers worldwide (7). The company reported full-year 2025 net earnings of US$2.30 billion and is forecasting continued growth in 2026. While Nutrien's core business is fertilizer, its expanding digital agronomy platform gives it meaningful exposure to the precision farming trend.

Deere & Co. (NYSE: DE) is the closest thing to a precision ag bellwether on public markets. Its See & Spray technology uses cameras and machine learning to identify and target weeds in real time, reducing non-residual herbicide use by nearly 50% across more than 5 million acres in 2025 (8). Deere is also pushing into autonomous tractors and AI-driven field analytics, making it the most direct large-cap play in the sector.

Merck & Co. (NYSE: MRK) is a name you might not associate with cow collars — but the pharmaceutical giant already makes them. Merck's Allflex and SenseHub divisions reached a milestone of 2 million dairy cows monitored globally in November 2025, and the company sells over 500 million animal identification tags per year (9). Merck paid US$2.4 billion (C$3.4 billion) to acquire this technology through its purchase of the Antelliq Group in 2019 (10). While it's a small slice of Merck's overall business, it's the most direct public comparison to what Halter is building — though Halter's virtual fencing capability is what sets it apart.

For broader exposure to the theme, AGCO Corp. (NYSE: AGCO) manufactures farm equipment and owns Precision Planting, a division focused on planting and application technology for row crops. CNH Industrial (NYSE: CNH) is similarly investing in digital farming tools across its Case IH and New Holland brands, both of which are common on Canadian farms. And Corteva (NYSE: CTVA) focuses on crop protection and precision application technologies, including partnerships with satellite imagery and data analytics platforms.

What Canadian investors should keep in mind

The themes driving Halter's valuation — labour shortages, drought-stressed herds, record-high beef prices — are not uniquely American. They're Canadian stories too. Here are a few practical steps investors can take to engage thoughtfully with this space:

1. Do your homework on Canadian-listed options first. Nutrien (TSX: NTR) is the most accessible Canadian-headquartered company with growing agtech exposure. Look at its Nutrien Ag Solutions division when evaluating the company's technology footprint.

2. Consider U.S.-listed agtech stocks through a Tax-Free Savings Account (TFSA) or Registered Retirement Savings Plan (RRSP). While U.S. dividends are subject to a 15% withholding tax in a TFSA, holding U.S. equities in an RRSP eliminates that withholding tax under the Canada-U.S. Tax Treaty. Deere, Merck and Corteva all pay dividends.
