Free agency by re-recruitment. No trade, immediate eligibility, an opaque price.
College player movement is an acquisition-and-retention market run by re-recruitment, not by trades, and it competes with the draft. The engine prices a portal target per destination, fit, and cost to land, at a wide band because the market is opaque and school-dependent, then reads retention as the same market from the other side, what it costs to keep a current player against his outside offers. A draft-eligible player carries the draft as a second outside option. And the moving portal rules, the windows, immediate eligibility, and tampering, ride the board as the contested, current-as-of constraints they are.
The same player is worth different amounts to different programs.
The same portal player is worth different amounts to different programs, because value is team-relative. His KR is translated within the Amateur engine across the amateur ladder to the target program's level, park, and role, and what matters is the team-KR delta he produces there. The acquisition price is a market read, wide-band because the portal market is opaque and school-dependent.
The same 80-KR outfielder translates to an 82 and a +2.4 move at the program with the hole, and a 78 and a +0.9 move at the one already deep, at acquisition prices that are wide bands because the market is opaque. Value is per-destination, and so is the price to land him. Per-destination value, per-destination price, both read as ranges because the market hides its numbers.
Illustrative engine read on the real per-destination portal valuation (the player's KR translated within the Amateur engine to each program's level, park, and role, the team-KR delta, the opaque wide-band acquisition price). Composite player and programs, demonstration figures; prices flagged v0 and current-as-of.
Keeping your own guy is an acquisition run in reverse.
The portal is also where a program loses players, so the read runs both ways: what it costs to retain a current player against his outside offers, priced the same way as an acquisition. And a draft-eligible player in the portal window carries the draft as a second outside option, so the retention price is read against both the portal market and the bonus.
Keeping a +2.0 player costs a package read against his best portal offer and, because he is draft-eligible, against his projected bonus too. Retention is an acquisition run in reverse, at the same opaque, wide band, and the draft is the second bid the retention number has to beat. Retention is acquisition from the other side, and a draft-eligible player has two outside options, not one.
Illustrative engine read on the real retention market (the cost to keep a current player against his portal outside offers, the draft as a second outside option for the draft-eligible, priced at the same wide band as an acquisition). Composite player, demonstration figures; prices flagged v0 and current-as-of.
Fast windows and immediate eligibility make it a free-agent market.
The rules ride the board as constraints: the entry windows, including the short window after a head-coaching change, unlimited transfers with immediate eligibility for academically eligible athletes, and the tampering risk that settlement-era enforcement raised. Together they make the portal a fast, low-friction free-agent market.
The windows gate when a player can move, immediate eligibility removes the friction that used to slow the market, and tampering enforcement is a live, contested risk, all flagged current-as-of. The rules make the portal fast and low-friction, which is exactly what makes it a free-agent market. Fast windows, immediate eligibility, an opaque price: free agency by re-recruitment, flagged current-as-of.

The portal is free agency by re-recruitment: no trade, immediate eligibility, an opaque price. The engine prices a target per destination and fit, reads retention as the same market from the other side, and carries a wide band because the market hides its numbers, treating the moving portal rules as the constraints they are. Value is team-relative and translated within the Amateur engine, a draft-eligible player has two outside options rather than one, and every dollar is flagged current-as-of and held in the Reference, because the portal prices itself in the dark.
Price the market from both sides.
The Transfer Portal prices a target per destination and fit at an honest wide band, reads retention as the same opaque market in reverse, treats the draft as a draft-eligible player's second outside option, and flags the moving portal rules current-as-of.
