Spectrum Sports requires anticompetitive conduct, specific intent to achieve monopoly power, and a dangerous probability that the attempt would succeed. Market definition and share evidence support the probability element.
Specific intent distinguishes it from monopolization.
Alternative Names:
Attempt to Monopolize|Attempted Monopoly
Why it Matters?
Dangerous probability requires substantial market share, and courts generally find shares below thirty percent insufficient regardless of intent evidence, which makes the element a threshold defense where the defendant's position is modest. Specific intent evidence in internal documents about defeating a rival is frequently the plaintiff's strongest material, and coaching sales and executive teams on competitive language is preventive rather than reactive.
