How our forecast works.

We pull from four public sources and combine them into a single forecast for every set in our catalog.

• PriceCharting — sealed, complete, and loose set prices, current and historical.
• Rebrickable — set metadata: themes, piece counts, minifigs, retirement years.
• Community — Reddit mentions across r/lego, r/legomarket, and r/legomania.
• Google Trends — search interest in the set or theme over time.

Every forecast comes in three flavors so you can see the full range of what could happen, not just one guess.

• Pessimist — what the price might do if demand softens, the set sticks around at retail, or the market cools broadly.
• Moderate — our base-case estimate, in line with how similar sets have behaved historically.
• Optimist — what could happen if the set retires early, collector interest accelerates, or a related franchise catches fire.

Each set gets a single plain recommendation based on its moderate-scenario projection.

• Buy — projected appreciation comfortably exceeds what cash or a broad index would earn.
• Hold — projected appreciation roughly keeps pace with the broader market.
• Sell — projected appreciation is flat or negative; the cash could likely work harder elsewhere.

Confidence tells you how much weight to give the forecast. It reflects how much historical data we have, how many similar sets we can compare against, and whether our signals agree with each other.

• High — long price history, lots of comparable sets, signals pointing the same direction.
• Medium — enough history to be useful, but some signals disagree or peer data is thin.
• Low — thin price history or conflicting signals. Treat the forecast as a rough indication, not a hard call.

LegoFuture is informational. Forecasts are model estimates — not guarantees. LEGO set values can be moved by re-releases, licensing news, broader economic conditions, and collector trends none of us can predict. Always verify prices before buying or selling.
