Getting the verb right is only half the job with escalate -- the preposition that follows it carries just as much meaning, and getting it wrong can quietly change what your sentence claims. "To" marks the recipient when you're routing ("escalate to your manager"), "to"/"into" mark a result or endpoint when nothing is being routed to a person ("escalate into a formal dispute," "escalate from a disagreement to a grievance"), "for" marks the purpose of an escalation ("escalate it to Legal for review"), and "by" marks the degree of a quantity change ("costs escalated by 12%") as distinct from "to," which marks the endpoint ("costs escalated to $2m").
Four prepositions, four different jobs
"To" marks the recipient when you're routing a matter to a person: "escalate to your manager." The same word, "to," also marks a result or endpoint when nothing is being routed to a person at all: "escalate into a formal dispute," "escalate from a disagreement to a grievance" -- here "into" and "to" both mark where the situation ended up, not who it was sent to. "For" marks the purpose behind an escalation: "escalate it to Legal for review" names why the matter is going to Legal, not just that it is. And "by" marks the degree of a quantity change, distinct from "to," which marks the endpoint: "costs escalated by 12%" describes the size of the change, while "costs escalated to $2m" describes where the number ended up.
Why mixing these up creates real confusion
Swapping "by" and "to" in a cost sentence is a common, consequential mistake -- "costs escalated to 12%" and "costs escalated by 12%" describe two entirely different situations, and a reader who catches the swap will reasonably wonder which one you meant. The same risk applies to confusing the recipient "to" with the endpoint "to": "escalated to my manager" and "escalated to a formal dispute" use the identical word for two different kinds of destination, and only context disambiguates them -- which is exactly why naming a clear recipient or a clear endpoint noun matters as much as picking the right preposition.

The fastest way to choose correctly in the moment is to check what follows the preposition, not just which preposition feels natural. If what follows is a person or a team, you almost always want "to" for the recipient. If what follows is a state or an outcome -- a dispute, a formal process, a more serious stage -- "to" or "into" mark that endpoint instead, and no recipient is implied at all. If what follows is a number describing the size of a change, "by" is the word doing that job, distinct from "to" marking where the number ended up. Running this quick check before finishing the sentence catches most preposition errors before they happen, rather than after a reader has already flagged one.
Four small words, four distinct jobs. Getting them right is what makes an escalation sentence read as precise rather than approximately correct.
