Canadian Pacific Kansas City Limited vs Union Pacific Corporation
WatchlistCP / UNPPrices through Oct 22, 2026
Why these are rivals: #1 and #3 by market value ($171B vs $77B) in Nasdaq's "Railroads" industry; SEC SIC 4011 / 4011 (same major group); #1 and #3 by market value ($171B vs $77B) with SEC SIC 4011 (Railroads, Line-Haul Operating).
Rivals, but right now the price gap does not have a measured habit of closing, so there is no paper idea, whatever the gap.
