Merger arbitrage is a mature, decades-old absolute-return strategy riding a near-record 2025-2026 M&A supercycle and a friendlier antitrust posture, but genuine public-equity exposure is thin — most specialist capital sits inside private multi-strategy funds, and the largest retail-accessible vehicle manages only around $2.4B.

| Indicator | Score | Reading |
|---|---|---|
| Maturity higher is better · high confidence | 82/100 | A decades-old, fully institutionalised absolute-return strategy riding a near-record 2025-2026 M&A cycle. |
| Evidence Strength higher is better · high confidence | 85/100 | SEC-filed fund disclosures plus reputable M&A/antitrust research houses; no peer-reviewed tier beyond index methodology. |
| Commercial Proximity higher is better · high confidence | 75/100 | Fee revenue is real and recurring at the largest named vehicles, but the public wedge is small and unevenly scaled. |
| Capital & Policy Support higher is better · high confidence | 59/100 | No public-funding analogue at all; the only relevant 'policy' lever is antitrust/merger-control posture, which is a completion-risk factor rather than a spend driver. |
| Crowding Risk lower is better · high confidence | 50/100 | Institutional capital is visibly crowding into the strategy even as the small public-vehicle sleeve shows no inflow surge. |
| Reflexivity Risk lower is better · high confidence | 43/100 | Position-level tail risk is genuinely high (deal breaks), but the theme is otherwise self-funding and earnings-grounded in contractual deal terms. |
