It gets proposed fairly often. The tricky part is detecting enough neutrinos in a coincidence window to make a meaningful trading signal.

Such an experiment is also very expensive.

A $300 million cable is being laid across the Atlantic just to cut off 5ms for high-frequency trading.[1] Bandwidth will cost 50x normal on that cable.

Neutrino experiments cost of order a billion dollars. The event rate for anthropogenic neutrinos sources at the MINOS detector (from the article) is a few hundred events over 1 year.

So the bandwidth for this state-of-the-art billionish-dollar detector is measured in μbps :)

Flipped over, if you can invent a reliable neutrino detector and influencer that costs say $150M you have a very risk tolerant market to sell into.

So you're saying there's a chance? /s

Spread Networks built a $300m line between Chicago and NJ just to save 3 milliseconds. That project involved building a tunnel.

Expensive for HFTs?

Expensive enough to not be profitable

Thankfully!
