Polygon’s MATIC token was the standout large-cap crypto asset on December 26, 2021, gaining 9.1% over 24 hours in two independent market records while bitcoin was nearly flat and ether declined. The move put MATIC close to $2.88 and gave the network token a market capitalization above $20 billion in CoinMarketCap’s dated snapshot.
The advance mattered because it arrived during unusually thin holiday trading and four days after Uniswap v3 went live on Polygon’s proof-of-stake chain. That juxtaposition supplied a plausible ecosystem narrative, but the available event-day evidence does not prove that the Uniswap deployment caused the token move.
What the market records show
Kraken’s report for December 26 listed MATIC at $2.8805, up 9.1%, with $38.0 million traded on the exchange. Among Kraken’s five most-traded assets, MATIC had the largest percentage gain; bitcoin rose 0.7% to $50,797, ether fell 0.8% to $4,064.30 and polkadot gained 8.7% to $31.35.
Kraken reported $579.6 million of total spot volume across all its crypto and fiat markets, compared with a 30-day average of $1.36 billion. The day’s total was therefore about 43% of that average, a Coinburn calculation using Kraken’s two published figures. Kraken also reported $208.0 million in futures notional. These are single-venue measurements, not totals for the global crypto market.
CoinMarketCap’s December 26 historical snapshot independently placed MATIC at $2.8768, up 9.10% over 24 hours and 29.45% over seven days. It ranked the asset 14th by market capitalization, at $20.412 billion, based on a reported circulating supply of about 7.095 billion MATIC. Its aggregated 24-hour volume was $3.215 billion. In the same snapshot, bitcoin gained 0.75% and ether lost 0.63% over 24 hours.
The close agreement between Kraken’s price and return and CoinMarketCap’s aggregated snapshot supports the direction and approximate scale of the move. The volume figures are not comparable: Kraken measured activity on its own markets for the dated session, while CoinMarketCap aggregated a rolling 24-hour window across venues. Crypto trades continuously, so there is no official consolidated close, and daily results depend on the venue, currency pairs, snapshot time and treatment of questionable volume.
The protocol context
On December 22, Polygon announced that all Uniswap v3 contracts had been deployed to Polygon PoS mainnet and that the network was available through Uniswap’s interface. Polygon said the deployment had passed Uniswap’s three-stage governance process. The expansion gave users another venue for decentralized swaps and liquidity provision without settling each interaction on Ethereum mainnet.
That was meaningful context for MATIC because the token was used for fees on Polygon PoS and Uniswap was a prominent Ethereum decentralized exchange. It was not, by itself, evidence of new token demand on December 26. Polygon’s announcement included publisher-supplied figures for wallets, transactions, applications and total value locked, but those claims are not needed to establish the market move and are excluded here because their methodologies were not provided in the release.
What can and cannot be concluded
The verified conclusion is narrow: MATIC rose about 9.1% on December 26 while bitcoin changed less than 1%, ether declined and Kraken’s overall spot activity remained well below its recent average. The token’s near-$2.88 mark and $20.4 billion snapshot capitalization made the move institutionally visible even on a low-volume holiday session.
The records do not identify the buyers, establish net capital inflows or isolate a catalyst. A rising token price after a protocol deployment can reflect expectations, market positioning, broader altcoin rotation or thin liquidity rather than measured adoption. Without venue-by-venue order books, dated fund flows and a defined event study, attributing the move to Uniswap would exceed the evidence available on December 26, 2021.
