What if the SEC approves spot Solana and XRP ETFs?
Spot SOL and XRP ETF approvals broaden institutional access; the cleanest expression is altcoin beta (ETH/SOL) outrunning BTC, with MSTR and COIN as levered equity proxies. The direct rhyme is the Jan-2024 spot-BTC ETF launch and the Oct-2025 first SOL ETFs — 'buy the rumor' ran into post-launch profit-taking. Forward angle: with approval increasingly priced, the inflow-vs-expectation gap matters more than the headline — fade the knee-jerk pop if Day-1 flows disappoint.
how we built this number — every step
The class rate is measured from our dated, sourced event library (decade-normalized Poisson — the full table is public at base_rates.json). The variant’s share within its class is the analyst’s editorial call, published so you can audit it. A wider range means thinner precedent. Full recipe: methodology · scored at Reality Check.
The butterfly cascade
How this trigger trickles across markets, left → right — the root shock, its first‑order moves, then the ripple effects. Drag any node; tap a market for its real price history.
Resolution timeline — how this probability is moving
Our model's odds (gold) over time vs the crowd's (Polymarket, blue), from the past toward the 0–6 months horizon. Each dot is a real macro event that nudged the probability — green pushed it up, red pushed it down. Tap a dot for the source. The gold path is an illustrative reconstruction anchored to today's estimate — real dated events, not a live re-estimate history.
What it would mean
If this plays out, it is a mixed shock. The SEC approves spot Solana and XRP ETFs, broadening institutional access. The trigger decomposes into signed root‑shocks — Crypto liquidity ▲ · Crypto confidence ▲ — which propagate through our causal graph to the markets below.
If it happens — the markets it would move
Biggest moves first. Projected moves are cascade-model priors; hist A–B% = what comparable past events actually did (measured abnormal returns), and model prior · unmeasured marks markets with no analogue backing yet. Tap any market for its price history.

Probable recommendation
Why we may diverge from history
Trust the cascade long on SOL/BTC/ETH/MSTR: negative prints are post-ETF-launch 'sell-the-news' single days inside a structural bull — exactly the asymmetry an XRP/SOL approval inverts; sample swamped by crypto beta.
Historical precedent — what analogous events actually did
Across 23 analogous events (overlap‑weighted), as abnormal returns — market beta stripped, so it's the event's own effect, not the market backdrop. Shown at 20 days (persistent) and 5 days (immediate); ↺ fades = the two horizons disagree. Confidence = consistency × sample × significance.

Why this probability
SOL ETFs already trading; XRP approvals imminent under friendly SEC, near-certain in 6mo. A base‑rate‑anchored prior, continuously scored against what actually happens — not a forecast.
