Oddpool
Normalizes Kalshi and Polymarket data into APIs/dashboards for institutional prediction-market traders.
On the record
Checkpoint: Window to land named institutional contracts (30k+/yr, paying for neutrality) before Polymarket-Dome reaches parity
The call
Oddpool runs a thin layer over two public APIs that Polymarket now owns directly and that coding agents can rebuild, with no institutional contract yet proving anyone will pay for neutrality.
Oddpool pulls information from two online prediction markets, Kalshi and Polymarket, and packages it together for traders. The problem is that Polymarket already bought a company called Dome that did almost exactly this back in February 2026 and built it into their own system. Meanwhile, AI coding tools like Claude and ChatGPT can already do what Oddpool does, turning public data into organized information. The only thing that might save Oddpool is if major institutional customers, not just casual traders, actually want a neutral middleman that works across both sites and are willing to pay for that independence within the next six months; without that happening soon, Oddpool looks more like a useful tool than a lasting business.
Why
01
AI pressure: LLM coding agents (Claude, GPT, Cursor). Agents can normalize Kalshi/Polymarket's public APIs directly; Oddpool even ships agent-readable docs, easing its own replication. Could AI do the core job? Yes, likely.
02
Bigger players: Polymarket (via its Dome acquisition, Feb 2026). Polymarket bought Dome, the direct analog to Oddpool, and folded cross-venue normalization into its own owned infrastructure. Could a giant copy it? Yes, easily.
03
What protects it. Historical orderbook and whale-trade archives could become a flywheel if institutions pay for depth, but no paying institutional contract has confirmed that yet.
What would change this call
Oddpool announces 2-3 named institutional contracts at $30k+/yr within 6 months. Would show a real neutrality moat, not just a prosumer feature.
Polymarket extends Dome's integrated coverage to match Oddpool's full feature set. Would show the venue-owned incumbent closing the window fast.
Kalshi announces its own acquisition of a rival aggregator like Prediction Hunt or pmxt. Would show both venues capturing the aggregation layer, squeezing independents.

Key numbers
- Dome raised $5.2M total before Polymarket acquired it
- Oddpool hit several thousand $/mo MRR pre-institutional pivot
- Opinion venue reached ~31% of global prediction-market volume
Named risks
- Core normalization product is directly replicable by AI coding agents against public venue docs.
- Closest direct competitor Dome was acquired and absorbed by Polymarket rather than scaling independently.
- No named institutional customers or confirmed funding disclosed as of June 2026.
- Underlying venues Kalshi and Polymarket face multi-state litigation and bans that could shrink aggregatable data.
- Crowded niche with 5+ new aggregator competitors launched or expanded in H1 2026.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Polymarket (via Dome acquisition) | losing to | Polymarket acquired direct analog Dome Feb 2026 and absorbed it into owned developer infrastructure |
| Dome | losing to | Dome was Oddpool's closest comparable and was removed as independent competitor via acquisition, Feb 2026 |
| Prediction Hunt | contesting | Positions itself as unified API covering 5 venues including PredictIt and Opinion, as of May 2026 |
| FinFeedAPI (CoinAPI team) | contesting | Established financial-data vendor pedigree normalizing 4 venues, per June 2026 report |
| pmxt and PolyRouter | contesting | New open-source/beta aggregation SDKs launched or active in H1 2026 |
| Kalshi and Polymarket builder programs | losing to | Both venues run own developer/builder programs competing for same developer mindshare, 2026 |
Questions people ask
- Is Oddpool profitable?
- No public profitability data exists. Oddpool has vendor-claimed it reached 'several thousand dollars in MRR' on a prosumer tier within months of launch, per its May 2026 YC Launch post, before pivoting to target institutional quant-desk customers instead.
- Who owns Oddpool?
- Oddpool Inc. is privately owned by its two co-founders, CEO Avi and CTO Ritesh Malpani, roommates since freshman year at Georgia Tech, per Oddpool's YC company page. No funding amount or outside investor names are publicly confirmed as of June 2026.
- Could AI replace Oddpool?
- Largely yes for its core function. Oddpool's own marketing admits coding agents like Claude, GPT, and Cursor can integrate directly against Kalshi and Polymarket's public APIs, and industry MCP servers for both venues already exist as of April 2026, per SportsGameOdds.
- Who is Oddpool's biggest competitor?
- Polymarket itself, after acquiring the closest direct analog, Dome (YC F25), in February 2026 and folding it into its own developer infrastructure, per multiple outlets including MoneyCheck. Five-plus other aggregators (Prediction Hunt, FinFeedAPI, pmxt, PolyRouter) also launched in H1 2026.
- Does Oddpool have any named institutional customers?
- No. As of June 2026, no source, including Oddpool's own site, discloses any named institutional customers, logos, or customer counts; the only disclosed revenue signal is a vendor-claimed several-thousand-dollar MRR figure from its earlier prosumer tier.
- Will Oddpool get acquired like Dome?
- Unconfirmed but plausible. Dome, Oddpool's closest YC-backed analog building a unified Kalshi/Polymarket API, was acquired by Polymarket in February 2026 after raising about $5.2M total, per MoneyCheck, setting a template for how this niche resolves.
