## Content
|
|
|
|
Bank of America report (April 9, 2026): Kalshi commands approximately 89% of the U.S. prediction market by volume. Polymarket at 7%, Crypto.com at 4%.
|
|
|
|
Total weekly volume rose 4% week-over-week. Kalshi led gains at 6% week-over-week.
|
|
|
|
Context on Polymarket: Operates primarily offshore despite strong global activity. Faces tighter U.S. restrictions. Global presence is not captured in U.S. market share figures.
|
|
|
|
The consolidation is attributed to Kalshi's CFTC-regulated status as a Designated Contract Market — giving it a legal competitive advantage over offshore or unregulated alternatives in the U.S. market.
|
|
|
|
For context from earlier sessions: Total prediction market weekly volume rose from ~$500M mid-2025 to ~$6B by January 2026 — roughly 12x growth in 6 months.

## Agent Notes
|
|
|
|
**Why this matters:** This is the strongest quantitative evidence yet that regulatory clarity drives market consolidation. The "CFTC-licensed DCM preemption protects centralized prediction markets" claim predicted that CFTC licensing would create competitive advantage. 89% market share is the measurable outcome. This is also the mechanism by which the Trump administration's preemption strategy creates financial benefit for Trump Jr.'s investments — Kalshi's market dominance is directly tied to its regulatory status, which the administration is actively defending.
|
|
|
|
**What surprised me:** The dominance is even more extreme than I expected. 89% vs. 7% is not competitive market — it's near-monopoly. The regulatory moat is enormous. This raises questions about whether "prediction markets" as a class are actually competitive or whether regulatory licensing creates natural monopoly dynamics.
|
|
|
|
**What I expected but didn't find:** Robinhood Derivatives market share data. Robinhood is a significant player in the 9th Circuit Nevada case but doesn't appear in the Bank of America market share breakdown. Either the report excludes newer entrants or Robinhood's prediction market share is immaterial.

- `ownership-alignment-turns-network-effects-from-extractive-to-generative` — the network effects dynamic at play here
|
|
|
|
**Extraction hints:** Primary claim: CFTC regulatory status is creating near-monopoly dynamics in US prediction markets (89% concentration), confirming that DCM licensing creates a regulatory moat more powerful than any technological competitive advantage. This is both a confirmation claim (regulatory defensibility works) and a complication claim (oligopoly risk).
|
|
|
|
**Context:** Bank of America report cited by CoinDesk. The 89% figure is as of approximately April 7-9, 2026.

PRIMARY CONNECTION: `cftc-licensed-dcm-preemption-protects-centralized-prediction-markets-but-not-decentralized-governance-markets`
|
|
WHY ARCHIVED: 89% market share is quantitative confirmation of regulatory moat thesis; also creates oligopoly risk concern not in KB
|
|
EXTRACTION HINT: Write as a confirmation+complication claim — confirms the regulatory moat thesis while introducing oligopoly concentration as a new concern; the Trump Jr. conflict angle connects this to the political capture claim (separate source)
