Across several ticket-resale marketplaces, get-in prices for Game 3 are hovering around $700, before fees, while lower-level tickets in many instances are surpassing $2,000 each—a sum not dissimilar to the final pricing for Super Bowl LIX in February. The get-in figure is also more than double the $300 low-end cost for the initial second-round Knicks playoff home game against the Pacers last year.  Monday’s Game 4 and a May 16 Game 6, if it happens, have a similar dynamic, with get-in prices starting at around $600. All of these figures have risen by about half just since the start of the Knicks-Celtics series three days ago.
