Bitcoin Logged Its First UTC Daily and Weekly Close Above $100,000

Coinbase’s BTC-USD market completed December 8, 2024 with a closing price of $101,174.99, the first time its UTC daily record—and the Monday-through-Sunday UTC week assembled from those daily records—finished above $100,000.

The close turned the six-figure threshold from an intraday breach into a completed-period market milestone. Bitcoin had first traded above $100,000 during the December 5 UTC session, but Coinbase’s candle for December 5 ended at $97,044.23 after ranging as high as $104,000. The distinction mattered to market participants using daily and weekly charts, although a chart close is a convention rather than a change to Bitcoin’s protocol or legal status.

What the Coinbase record shows

Coinbase’s 86,400-second candle beginning at 00:00 UTC on December 8 records a $99,919.20 open, $98,729.66 low, $101,435.05 high and $101,174.99 close. The exchange reported 4,230.35225168 BTC of base-asset volume in that bucket.

Coinburn calculates a 1.26% open-to-close gain for December 8: ($101,174.99 / $99,919.20 − 1) × 100. For the UTC week beginning December 2, the comparable return was 4.03%, measured from Coinbase’s $97,259.17 December 2 open through the December 8 close. Adding Coinbase’s seven displayed daily volume fields gives 114,187.97430796 BTC for the same interval. That sum is venue volume, not global bitcoin turnover or dollar value.

The sequence around the threshold was uneven. Coinbase recorded closes of $97,044.23 on December 5, $99,891.35 on December 6 and $99,929.32 on December 7 before the December 8 finish above $100,000. Contemporaneous December 8 reporting likewise identified the move as bitcoin’s first weekly close above the round-number level.

A close depends on the clock and venue

Bitcoin trades continuously and has no consolidated global closing auction. “Daily close” here means the last Coinbase BTC-USD trade grouped into a UTC calendar-day candle. “Weekly close” means Coinburn’s aggregation from 00:00 UTC on Monday, December 2 through the end of Sunday, December 8. A platform using another exchange, index, timezone or cutoff can report a different number.

Coinbase’s documentation says candle arrays contain time, low, high, open, close and volume. It also warns that historical rates can be incomplete and that no candle is published for intervals without ticks. Those limitations do not undermine the existence of active BTC-USD trading in this heavily traded week, but they prevent the Coinbase figures from being presented as a universal benchmark.

Why six figures carried institutional weight

The December 8 finish followed the January 10 approval of exchange-rule changes that allowed U.S. spot bitcoin exchange-traded products to list and trade. That decision expanded access through conventional securities accounts without making bitcoin government-backed, eliminating spot-market risks or turning an exchange price into fundamental value.

Associated Press reporting on December 5 also placed the first $100,000 crossing in the context of Donald Trump’s November 5 election victory, his stated crypto-policy ambitions and his December 4 plan to nominate Paul Atkins to chair the Securities and Exchange Commission. Those were contemporaneous explanations for market sentiment, not proof that any one political announcement caused the December 8 close.

What December 8 established

The narrow conclusion is strong: on Coinbase BTC-USD and under a stated UTC convention, bitcoin completed its first daily and weekly period above $100,000 on December 8, 2024. The milestone showed that buyers sustained six-figure pricing through a period boundary after the sharp December 5 reversal.

It did not establish that $100,000 had become permanent support, identify the investors behind the closing trades, or show that exchange-traded products or politics caused the result. It was a verified market record bounded by venue and clock—not a forecast.
