Bill Cipher's IQ, what the methodology actually says.
"Bill Cipher's IQ" is a popular search. TV Intelligentsia doesn't invent IQ numbers for fictional characters. Here's the honest answer, the show's IQ Score, and what it tells you about how seriously the work treats his mind.
The honest answer
TVI scores shows and films, not characters. Assigning an IQ to a fictional character would be fabrication, we don't have a methodology for that. What we do have: a 0–200 rating of the work's structural intellectual quality, and that score tells you something real about how seriously Gravity Falls treats Bill Cipher's mind.
Who Bill Cipher is, and what kind of intelligence the show actually depicts
Bill Cipher (Alex Hirsch (voice)) is the interdimensional dream demon and primary antagonist, a being of pure information whose intelligence is manipulation rendered as something close to omniscience. The character's intellectual signature in the show is manipulation-as-omniscience, deal-making logic that trades in what people most want, the predatory cognition of an entity that understands every mind in the room better than the minds understand themselves.
This is the part of the question "what is Bill Cipher's IQ" that the search engine flattens. The real question, the one viewers are circling, is whether the show treats his mind seriously. That's the question TVI can actually answer.
What the IQ Score reveals about the portrayal
Gravity Falls scores 158/200 (Stimulating tier), and Bill Cipher is the reason the show's threat architecture reads as genuine rather than as cartoon villainy. The rubric rewards how seriously Hirsch's series treats Bill's intelligence: his deals carry real stakes, his foreknowledge is dramatized rather than asserted, and the second-season turn where his long game becomes visible recontextualizes earlier episodes. The Cognitive Stimulation score of 44/50 reflects exactly this, a children's show that asks its audience to track a manipulator whose plans were laid in plain sight episodes earlier.
