Activate Backspin+The same Backspin signals, from your own wallet. Setup takes about 10 minutes.

Settled tennis sides on Polymarket: Backspin (incl. overlays) since Jul 21, 2026 PT, unique signals bought by at least 3 wallets. Record is 107–57 across 164 settled signals (65.2% win rate); each game side is counted once regardless of the number of fills. The +767.5% figure is summed trade ROI, not portfolio return. Individual trade ROI is calculated from entry price to settlement, and losses are counted at −100%. The record above counts every closed signal. A share of the cards are sealed, wins and losses together, so the grid is not a complete tape. Open cards link to the market where they settled. Cards are ordered by entry time, not settlement time. Open positions are not shown. Past performance is not a guarantee of future results.

How Rainmaker works

Four steps, about 10 minutes. Backspin+ handles the games from there.
