Gambling.com Group (NASDAQ: GAMB) and SharpLink Gaming (NASDAQ: SBET) share a sports betting origin story, but their most recent earnings reveal two companies with almost nothing in common. One is building a recurring-revenue data business. The other has reinvented itself as a crypto treasury vehicle.
Sports Data Lifts GAMB. Ethereum Defines SBET.
Gambling.com just reported Q3 2025 revenue of $39.0 million, up 21.4% year-over-year, with the real story inside the segment breakdown. Its sports data services unit, powered by OpticOdds and OddsJam, posted 304% year-over-year revenue growth and now represents 24% of total quarterly revenue. That is a meaningful shift for a company historically dependent on affiliate marketing clicks.
CEO Charles Gillespie was direct:
“It is increasingly clear to us that OpticOdds has product market fit in a multi-billion-dollar sports data services market. The high-margin, high-visibility, recurring subscription revenue associated with our sports data services business is the fastest growing part of our business.”
Subscription revenue is stickier than performance marketing, and the enterprise sales pipeline at OpticOdds appears to be accelerating.
SharpLink’s story is completely different. The company pivoted to an Ethereum treasury strategy in June 2025 and has not looked back. By year-end, it held 864,597 ETH and had raised approximately $3.2 billion in capital to fund accumulation. Q4 staking revenue came in at $15.3 million, missing the $17.33 million consensus estimate by 11.7%, but the GAAP net loss of $734.6 million dominated headlines. Nearly all of that loss traces to a $616.2 million unrealized ETH markdown and a $140.2 million LsETH impairment, both non-cash.
One Builds a Media Moat. One Bets on Ethereum Cycles.
| Lens | GAMB | SBET |
|---|---|---|
| Core Business | Affiliate marketing + sports data subscriptions | Ethereum treasury accumulation |
| Revenue Driver | OpticOdds/OddsJam enterprise sales | ETH staking yield |
| Key Risk | Search quality headwinds in marketing segment | ETH price volatility, GAAP fair value distortions |
| Institutional Ownership | 43.4% | 46% (up from ~6%) |
GAMB’s vulnerability is its marketing segment, where search quality headwinds from spam websites began in July and persisted into Q4. Performance marketing revenue fell 4% year-over-year in Q3. Gillespie expects resolution in 2026, but that remains a forecast.
SBET’s vulnerability is more direct: ETH dropped roughly 45% from its January 2026 peak of $3,687 to around $2,013 currently. CEO Joseph Chalom’s response: “Crypto markets move in cycles, but our strategy is consistent and designed to endure.” That may be true, but it is also exactly what any ETH bull would say at the bottom of a drawdown.
Which Strategy Holds Up Through 2026?
The key question for GAMB is whether data subscription revenue can fully offset the marketing drag. North America grew 55% year-over-year and now represents 51% of revenue, a healthy sign. GAMB trades at ~1x price-to-sales, with analysts setting a consensus target of $8.50 suggests the market is pricing in continued pain before recovery.
For SBET, the metric that matters is ETH per share, which doubled from 2.0 to 4.01 during 2025. If ETH recovers, that compounding shows up fast. If it does not, GAAP losses keep piling up and the $1.5 billion share repurchase authorization looks misaligned for a company still accumulating crypto.
Two Very Different Investor Profiles
GAMB trades at ~1x price-to-sales, with analysts setting a consensus target of $8.50. The data subscription segment is growing rapidly while the marketing segment faces headwinds. The OpticOdds subscription model adds recurring revenue alongside the affiliate marketing business.
SBET carries a beta of nearly 12 and a 52-week range of $2.28 to $124.12, reflecting its direct exposure to ETH price cycles. Institutional ownership has risen to 46% since the ETH treasury pivot.
