Polymarket announces building its own L2, does this mean Polygon's flagship is gone?

On December 22, news about prediction-market leader Polymarket triggered widespread market attention—Mustafa, a member of the Polymarket team, confirmed in the Discord community that Polymarket plans to migrate from Polygon and launch an Ethereum Layer2 network called POLY, which is the project’s top priority for now.

A Breakup That Wasn’t Exactly Unexpected

Polymarket choosing to jump out of Polygon isn’t particularly surprising. One is a representative of an up-and-coming application-layer hit, and the other is an old underlying layer that’s gradually fading into obscurity—so the market heat and value expectations between the two were already somewhat mismatched. As Polymarket grows into a new behemoth, Polygon’s lack of network stability (the most recent outage occurred on December 18) and the relatively weak ecosystem have objectively become constraints on the former.

For Polymarket, building its own portal means a win-win choice across two dimensions: product and economics.

On the product side, besides seeking a more stable operating environment, building its own Layer2 network can help Polymarket tailor underlying characteristics in reverse according to the platform’s needs, making it more flexible in adapting to future upgrades and iterations of the platform.

And more importantly, the significance shows up on the economic side. Building its own network means Polymarket can bring together the economic activities and surrounding services derived from its platform into its own system, preventing related value from spilling over to external networks—so that, step by step, it becomes a systemic advantage of its own.

Explicit and Implicit Economic Contributions

As an application-layer player, Polymarket’s explosive surge once brought Polygon objective, direct economic contributions. Data analyst dash’s data compiled on Dune shows the following historical trends:

· Polymarket’s monthly active users are 419,309, with a historical total user count of 1,766,193;

· The total number of monthly transactions is 19.63 million, with a historical total of 115 million transactions;

· The total trading volume for the month is $1.54B, with a historical total of $14.3 billion.

As for how to assess Polymarket’s share of contributions to Polygon’s ecosystem economy, Odaily Planet Daily found a rather coincidental ratio when compiling both parties’ data.

· First, with regard to capital that gets settled/locked in: Defillama data shows that the current total value of Polymarket’s positions across the whole platform is about $326 million, roughly a quarter of Polygon’s total value locked of $1.19 billion;

· Second, regarding gas consumption: Coin Metrics reported last October that transactions related to Polymarket were expected to consume 25% of Polygon’s total network gas;

· Considering that this data is somewhat outdated, we checked recent changes again: a statistical chart drawn by data analyst petertherock on Dune shows that in November, the total gas consumed by Polymarket-related transactions was about $216k, while Token Terminal’s statistics show that Polygon’s total gas consumption for that month was about $939k, with the proportion similarly close to one quarter (about 23%).

Of course, there may be coincidence caused by differences in statistical scope and time windows, but cross-dimensional similarities can still, to a certain extent, serve as a reference for estimating Polymarket’s economic significance to Polygon.

Beyond measurable indicators such as active users, settled capital, trading flow, and gas contributions, Polymarket’s economic significance to Polygon also lies in a series of implicit contributions that are harder to quantify directly, yet are equally real.

First is activating stablecoin liquidity. All Polymarket transactions are settled in USDC. Its high-frequency, continuous trading behavior objectively and significantly increases the demand for, and the usage scenarios of, USDC circulating on the Polygon network; second is the added behavioral value of retained users—besides the prediction market itself, these users may also, for convenience, shift toward using other products in Polygon’s DeFi ecosystem, thereby increasing the overall ecosystem value of the Polygon network. These contributions may not be easily quantified into very concrete data, yet they form the “real demand” that the underlying network cares about the most—and that is also the rarest.

Why Now? The Answer Isn’t Hard to Guess

In fact, purely in terms of user scale, data performance, and market noise, Polymarket has already fully built the confidence to go independent. This has long ceased to be a question of “whether it should leave,” and instead is a question of “when it should leave.”

The reason it chose to start the migration at this time point is **most likely because Polymarket’s TGE is approaching. On the one hand, once Polymarket finishes issuing its token, its governance structure, incentive system, and economic model will become relatively fixed, and the costs and complexity of migrating the underlying layer afterward will rise significantly; on the other hand, upgrading from a “single application” to a “full-stack system of application + underlying layer” inherently means a change in valuation logic—**building its own Layer2 will undoubtedly give Polymarket a higher ceiling in both narrative and capital terms.

In short, Polymarket leaving Polygon is, in essence, not just a simple underlying-layer migration—it’s a snapshot of structural changes across the crypto industry. When top-tier applications start to be able to independently carry users, traffic, and economic activity, if the underlying network can’t provide additional value, it will inevitably get “stabbed in the back.”

No other reason—people are just after profit.
