Berkshire Hathaway Class B shares hit intraday record $543.06

The significance here is less the record itself than the breadth: both share classes setting all-time highs in the same session points to demand across the investor base rather than a single order flow quirk. It matters most to long-term holders and to anyone tracking Berkshire as a defensive benchmark against crypto and other risk assets, since fresh highs in a diversified operating business can signal where capital is seeking shelter. Whether the move holds through the close, or fades as an intraday spike, is the open question worth watching.
