Bruno Mars holds overwhelming market-implied odds at 99.8% to finish as the top Spotify artist for October 2026, driven by his sustained dominance in monthly listeners. He has led the platform’s daily artist rankings with roughly 127 million listeners as of October 30, a margin of about 10 million over Rihanna and The Weeknd, after holding the top spot for at least 90 consecutive days. Strong ongoing streams for tracks such as “Risk It All” and continued Billboard chart success have anchored this position through the month. With only hours remaining before October ends, an upset would require an unprecedented final-day surge from a competitor that overcomes the existing gap, a scenario traders view as highly improbable given current momentum.
