Significant divergence exists. Mainstream media reports (e.g., Axios, Politico) confirm Musk has become a major GOP donor in early 2026, shifting his strategy entirely to 'internal influence.' However, the prediction market still assigns a ~14.5% probability to him registering a new party. This pricing represents a classic 'tail risk overestimation,' where the market is pricing in a premium for Musk's personal volatility and unpredictability rather than the actual political probability.
